This paper describes research on peripheral technologies for hydrogen. For the cost of manufacturing hydrogen from different primary energies, coal gasification could be the lowest at the present time. In the nuclear power field, the thermo-chemical method and the water electrolysing method may be assumed, but they depend greatly on future technological development. Particularly the water electrolysing method is dependent on electric power cost. In the hybrid method, hydrogen is obtained from electrolysing reaction with water of sulfur dioxide derived by paralyzing sulfuric acid (oxygen is also generated). The method requires two forms of energies, heat and electric power, whereas combination with a very high temperature reactor (VHTR) is being discussed as a heat source. This method may not be said greatly more advantageous than the direct water electrolysis, but may have future possibility. Hydrogen manufacturing utilizing living organisms is an interesting matter in terms of science and engineering, with a large number of research achievements beginning to appear. Expectation is drawn on the mechanism based on co-work of photosynthesis and a hydrogen generation system, alga and bacterium strain search, separation, cultivation, and applied research and development. Research is also under way to obtain hydrogen by converting photo-energy by using an electrochemical photo-cell utilizing semiconductor electrode to electrolyse water (color sensitizing) (NEDO)

With relation to the coal of the Philippines, where the expansion of the use of coal as a substitute for petroleum/plant fuel is aimed at, the paper grasped the situation of coal production/development, the trend of coal import and domestic distribution, the coal utilization trend, and environmental problems, and analyzed the situation of coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to draw up a master plan for the introduction of the environmentally-friendly coal utilization system. As to the use of environmentally-friendly coal technology which should be adopted to the coal mining industry and commercial/residential sector, cited are the introduction of coal preparation technology and power transmission technology, and the development/spread of briquette as a firewood substituting fuel. In the electric power sector, the problem is the treatment of ash after combustion and the effective use. Relating to the treatment of flue gas, there is no installation at all of desulfurization facilities and denitrification facilities. In the cement industry sector, they wish to return fuel from heavy oil to coal. For it, it is necessary to study dust preventive measures. In the other sectors, coal hasn`t been used very much. An increase in coal demand is not expected also in the future, and big problems concerning coal haven`t occurred. 42 figs., 64 tabs.

For every solar energy utilization field, its background, feasibility, impact in practical use, and R and D policy in Japan were studied. Heating and hot water supply by solar energy are already practical because of less technical problems and reasonable profitability, and cooling is also practical as far as a technical viewpoint. At present, the technical level of solar heat power generation is in the stage of basic technology, however, in the future, development of economically reasonable systems will be demanded as well as establishment of its technology. The most difficult problem for realizing practical solar cell power generation systems is cost reduction. It is also another problem that a big demand of Si for solar cells further exceeds the current yield of Si in a semiconductor industry. A small-scale hybrid solar cell power generation system applicable to the roof of general residences is already feasible. Although a solar furnace is still poor in application to industrial fields, it is expected as the leading part for a future solar heat chemical industry. (NEDO)

Grasping the present situation of coal utilization technology in the Philippines, the paper proposed a feasibility study of introduction of the environmentally friendly type coal utilization system which seems to be needed in the future. (1) Introduction of the environmentally friendly type coal utilization system in the electric power generation sector: there are only four full-scale running coal thermal power plants in the Philippines. In the future, several coal thermal plants are planned to be constructed by 2005, but for the new installation, it is desirable to adopt fluidized bed boilers with wide application to coal kinds. In case of 0.3-1.0 million MW class plants, it is planned to adopt high grade import coals, and it will be natural to fire pulverized coal. For the processing of flue gas, it is a must to install desulfurization facilities and smoke/soot removal devices. (2) Utilization/development of domestic low grade coals: at the mine-mouth generating plant, it is necessary to investigate the economically minable amount of coal, confirm productivity, survey coal quality, etc., and select boiler. As to coal briquetting technology, it is necessary to examine coal quality for tests and make a thorough study of what technology is most suitable. 50 figs., 78 tabs.

This survey arranged the status of coal utilization technology and the status of coal production, supply, etc. in Malaysia and Vietnam, examined/studied coal utilization systems in both countries, and finally assessed feasibility of introducing the environmentally friendly type coal utilization system. As a country of primary energy source which is abundant in crude oil, natural gas, hydroelectric power, coal, etc., Malaysia now depends on crude oil and natural gas for 80% of its energy, and places emphasis on exploration of natural gas and oil refining. In electric power and cement industries where coal is consumed, effectiveness and environmental issues in association with coal utilization are future subjects. In Vietnam, the north is abundant in hydroelectric power and anthracite, and the south in oil and gas resource, but the north and central districts are in a state of undevelopment. Coal is used for coal thermal power generation, cement industry, and residential/commercial fuel. In the future, effective coal utilization and environmental issues will be subjects. 16 refs., 38 figs., 75 tabs.

A survey was made in India which is a coal producing/consuming country following China in Asia and where coal is used for about 60% of the primary commercial energy. The survey was conducted on coal production/distribution/utilization and environmental issues, aiming at studying feasibility of introducing the environmentally friendly coal utilization system into every industry including the residential/commercial one, and at implementing a comprehensive master plan including Japan`s international cooperation. Total power source facilities in fiscal 1995 are 83.3 million kW, 64% of which are coal thermal power facilities and generated 260 TWh, 69% of the total output energy. Main commercial energy sources are coal, oil and natural gas, and oil is self-sufficient. The survey this time did not examine very well the actual state of the environmental pollution problem caused by the coal utilization. Indian coal is high in ash content but low in sulfur content, and therefore, SOx polluting air has not been a very important problem so far, but soot/smoke is almost the problem. Further, ash treatment after combustion at boilers, etc. is expected to be a big problem in the future. 49 figs., 88 tabs.

Taking the area of the clean coal technology (CCT) effective for energy conservation and environment preservation as the object, a feasibility survey has been performed on executing a model project in India. About 70% of the total power generation capacity in India depends upon coals existing in abundance inside the country. Since the local coals are high in ash, low in sulfur, and low in calorie, the environmental problem related to thermal power plants is the disposition of fly ash. The Central Electricity Authority of India expects solving this problem by CCT introduction. It also expects increase in combustion efficiency by using ultra-critical boilers. The Indian cement industry often uses in-house electric power generation facilities because of high electric power cost, wherein the produced coal ash is used as a cement raw material. The matter of the strongest interest is the introduction of a high-efficiency combustion system that depends on low-grade coals. Among the CCTs, strong interest was shown in the fluidized bed cement kiln and the circulating fluidized bed boiler. The iron and steel industry has expectations toward effective coal washing technologies and coke manufacturing technologies. (NEDO)

For collecting solar radiation data necessary for the prediction of power to be outputted by photovoltaic power systems in Japan, detailed experiments and observations were conducted with an emphasis placed on the amount of solar radiation on a slope facing north and on the amount of solar radiation broken down by wavelength. Models were analyzed, and the fiscal 1999 results were compiled. In the validation of a model of solar radiation on an inclined surface, a review was conducted using the 1-year data observed at the Takasaki station for all directions, including solar radiation on the slope facing north, and the validity of the model was confirmed. As for the validation of a model for estimating solar radiation by duration of sunshine, it was examined for accuracy using the same data, and was found to be fairly high in accuracy. For the maintenance of solar radiation data for each wavelength, continuous observation was conducted for each wavelength of solar radiation at the Takasaki station using a multi-filter spectroradiometer, and a technique was established to determine spectral distribution using the observed data. Moreover, continuous observation of global diffused solar radiance was conducted using a sky scanner at the said station and solar cell power generation characteristics was continuously monitored.

An apparatus is developed to establish a system which allows utilization of hydrogen safely and easily, and its applicability to a hydrogen system for domestic purposes is tested. The system converts solar energy by the photovoltaic cell unit into power, which is used to generate hydrogen by electrolysis of water at the hydrogen generator, stores hydrogen in a metal hydride , and sends stored hydrogen to the burner and fuel cell units. It is found that a hydrogen occluding alloy of LaNi4.8Al0.2 stores hydrogen to approximately 80% when cooled to 20 to 25degC, and releases it to 10% when heated to 40degC. The fuel cell uses a solid polymer as the electrolyte. The hydrogen gas burner is a catalytic combustion burner with a Pt catalyst carried by expanded Ni-Al alloy. The optimum distance between the burner and object to be heated is 22mm. High safety and fabrication simplicity are confirmed for use for domestic purposes. The system characteristics will be further investigated. 4 refs., 8 figs.

This research and development project is aimed at treatment of sewage, industrial waste water and the like at lower cost for reutilization, while efficiently producing methane or the like by the systems annexed to the water treatment systems with high-concentration bio-reactor systems incorporating separation membranes. The waste water types studied to be treated by these systems include sewage discharged in large quantities and waste water containing oil/fat and protein (low-concentration waste water), and starch-, alcohol and paper/pulp-containing waste water, and excrements (medium-concentration waste water). The project has found the optimum systems, by adequately configuring the separation membrane modules, and combining dissolution of suspended solid with methane fermentation reactors for selective treatment of organic substances; improved efficiencies of removing organic substances and producing methane by fermentation, and realized reduction in quantities of discharged sludge; and thereby established the bases for the new waste water treatment techniques. The reactor systems developed for water treatment are those based on biological removal of nitrogen. They greatly reduce treatment time to produce treated water of high quality. For treatment of sludge, the techniques have been developed to convert sludge into oil. These results are well applicable to various areas, e.g., sewage treatment, and food and pulp industries.

Surveys and studies were performed on chemical utilization of hydrogen regarding its status of development and utilization inside and outside the country, as well as its future prospect. This paper describes chemical utilization of hydrogen in ammonia, methanol, petroleum refining and other industries as the existing fields. It also describes chemical utilization of oxygen in iron and steel, chemical and other industries. It describes methanol as a pollution-free auxiliary fuel for electric power plants as a new type of hydrogen application. Acetic acid made by using the Monsanto method which carbonylate methanol is drawing attention in terms of economy, and is in the phase of discussing commercialization. Synthesizing ethylene glycol from carbon monoxide and hydrogen may be conceived economically. Methanol for synthesized protein depends on the possibility of future development. In the iron and steel industry, electric furnace steel makers are planning production of reduced iron, where the direct reduction process using hydrogen is considered as a complementary process, including countermeasures for scrap iron. This paper estimates hydrogen amount as a raw material for ammonia to remove NOx by using the ammonia reduction process. It also describes possibility of other types of utilization. (NEDO)

This paper reports on the present situation of the chemical use of hydrogen and oxygen, and the short-term, medium-term, and long-term forecast. The main usage of hydrogen is ammonia synthesis, petroleum refining, and methanol synthesis. In the usage of these three, there are factors of structural changes now and in future, and it is extremely difficult to predict the amount in a short term up to around 1980. In a medium term prediction, from the result of predicting the demand of ammonia, methanol and hydrodesulfurization, the total 1985 hydrogen demand is estimated at approximately 60 billion Nm{sup 3}, and approximately 67 billion Nm{sup 3} as the gross hydrogen demand. Further, judging from that synthetic protein, fuel use methanol, and reduced iron are estimated to reach a certain production size in and after 1985, new demand for hydrogen is expected to be approximately 100 billion Nm{sup 3} mostly including fuel use methanol. In a long term prediction, it is extremely hard to predict the demand because of various factors existing in Japan and abroad. As predicted in a medium term, the amount of chemical use of hydrogen is expected to increase more and more, even if calculating it only in the field of ammonia synthesis, petroleum refining, and methanol synthesis.

A permanent borehole energy storage system utilizing solar energy and waste heat from coolers is simulated, to be used as an air conditioning system for super-tall buildings. A 100m-long pipe is buried vertically into the ground, and a heat medium is caused to circulate in the pipe for the exchange of heat with the soil. Thirty borehole units are used, each measuring 9m{times}9m (with the pipe pitch being 3m). Solar cells occupying half of the wall surface facing south and solar collectors installed on the roof supply electric power and heat for cooling and warming. Heat in the ground is transferred mainly by conduction but also is carried by water and gas in movement. So, an analysis is carried out using an equation in which heat and water move at the same time. Because waste heat from cooling and warming systems is accumulated in the ground and none is discharged into the air, big cities will be protected from warming (from developing heat islands). As compared with the conventional boiler-aided air conditioning system, a hybrid borehole system incorporating solar collectors and solar cells will bring about an 80% reduction in CO2 emission and annual energy consumption. 7 refs., 3 figs., 4 tabs.

Values given to global environment and economy by utilization of photovoltaic power generation are evaluated, and quantified to make clear the significance of the utilization thereof. Specifically, trial calculations were performed on LCA and damaging characteristics of photovoltaic systems, and reducible amount of carbon dioxide emission. Taking up thin film CdTe cells as the object, estimation was made on the energy payback time (EPT) and CO2 emission amount. The production scale ranges over 10 MW/ 30 MW/ 100 MW annually, the useful life is 20 years, and the unit requirement for CO2 emission originated from the charged electric power is 114 g-C/kWh. The EPT was 1.74 in the annual production of 10 MWp, 1.08 in 100 MWp, the unit requirement for CO2 emission was 14.0 in the annual production of 10 MWp, and 8.9 in 100 MWp. This is one of severals of that in the existing power supply source. For heavy metals, particularly Pb, the trial calculation resulted in 0.15 g/Wp in the crystalline type, and 0.1 g/Wp in the amorphous type. The problem therewith is separation and recovery. The reducible amount of carbon dioxide, or in other words, the amount of power that can be generated latently is 37,235 GWh/year, or 3.10 million tons when converted into carbon dioxide. (NEDO)

Described herein are the final evaluation results obtained by the 7-year R and D project, beginning in the FY 1976, established by the national project system for developing the techniques for treating urban solid wastes. This project has developed a semi-wet type selective crushing/sorting unit for sorting the wastes, and established the elementary techniques for recycling the wastes into various products, e.g., compost, pulp, combustible gases, aggregates, methane gas, or fuel oil. Two types of total treating systems, in which these elementary techniques are integrated, have been developed; one is to recover materials and the other energy. They can comprehensively, efficiently treat the wastes, adapting themselves to various situations. Pyrolysis which discharges reduced quantities of flue gases is adopted. Waste water is treated, mainly by biological treatment which is supported by the conventional methods, e.g., coagulation and adsorption. The cost estimation results indicate that the total system developed by this project can compare favorably with the conventional incineration system under general conditions, at a capacity of 300 t/d or more, when taking into consideration the secondary effects brought by the recycling/reutilization. This system is commercially feasible, when it meets with local characteristics, e.g., garbage collecting systems, market values of recycled resources, treatment/disposal conditions, and natural and social environments. This project has sufficiently achieved the original objectives. (NEDO)

As for their outputs, the 3kW separately-excited and self-excited photovoltaic power plants yield daily averages of 7.8kWh and 6.9kWh, respectively, and this means that the self-excited type is inferior to the separately-excited type in terms of conversion efficiency. Automatic measuring devices for photovoltaic characteristics are installed at Sapporo, Sendai, Nagoya, and Miyazaki, which will elucidate regional difference in photovoltaic characteristics. A simulation of photovoltaic characteristics is performed and the resultant value is compared with the yield of an experimental 3kW system, and the result of the comparison is found reasonable. Cell arrays are subjected to investigation for configurations lowest in output loss for the respective shadow patterns. Harmonic characteristics are analyzed under plural-interconnection circumstances. Studies are made to miniaturize and simplify system constituents, and it is found that a 3-hour storage is proper for a 3kW-class storage battery. It is also found that a self-excited type suffers less voltage fluctuation in interconnected operation on a small short-circuit capacity system. Possibilities are that independent operation is started when output is larger than load, which is to be detected by checking changes in phase, frequency, etc. Array configuration, arresters, and shielding wires are taken up for the study of measures to cope with direct thunder strokes.

This project is aimed at surveys and researches on operation, economic efficiency and performance evaluation of solar thermal power generation systems, and test methods, e.g., for aging the materials for their devices, in order to establish the methods for evaluating their performance. For operation of solar thermal power generation systems, a feasible system is a hybrid with another system, e.g., thermal power or nuclear system. For economic efficiency, heat-storage capacity will be based on power generation for around 4 hours a day for a solar system to be installed in Japan. The construction and light/heat-collecting costs should be reduced to around 300,000 yen/kW and 13,000 to 21,000 yen/m{sup 2}, respectively, in order to keep the power generation cost at around 23 yen/kWH. The energy analysis of solar thermal power generation, based on the data given by the industrial correlation tables, indicates that the total energy required for construction of the system can be recovered in 2 to 3 years. Also outlined are construction of a 1MW pilot plant and its facilities, and designs of the pilot plants with a curved surface or tower type light collector. A total of 12 types of reflection mirrors are screened for establishing the air-exposure testing methods. Methods for treating back surface edges of the reflection mirrors are also investigated.

Wastewater reuse can be considered as a type of water resource development which is expected to improve the aquatic environment, as well as the stability and reliability of municipal water supply systems. To this extent, wastewater reuse has been taken into account in the planning of water supply systems in several Japanese cities. However, to date the effect of wastewater reuse on water supply system stabilization has not been discussed quantitatively, and the relation between waster water reuse rate and water supply system stability has not been analyzed. In this study, a stochastic model has been presented to evaluate the stability of water supply systems with optimal wastewater reuse rate. Some theoretical analyses and numerical studies were performed, and all of the results have shown that the model is reliable for not only basic studies on water supply system stability, but also for practical use as well. 5 refs., 5 figs., 3 tabs.

This metal melting system is a process to efficiently melt and regenerate scraps of aluminum, copper and iron by utilizing high-temperature energy obtained from pulverized coal-oxygen combustion. The process is intended to utilize coal in place of petroleum for reduced fuel cost. Joint studies have been carried out as a subsidy operation of the Agency of Natural Resources and Energy with a schedule of six years starting fiscal 1992. Development tests are being performed using a 5-ton/ch pilot plant facility since fiscal 1995 after having gone through experiments using a 1-ton/ch bench scale furnace. This paper reports the results obtained to date. Using the pilot plant facility, fiscal 1995 has achieved the initial target values, such as thermal efficiency of 55% or higher, and yield of 96% or higher for non-ferrous metals and 94% or higher for iron. The melting behavior in the furnace has improved the thermal efficiency as a whole by retaining the conditions in the preheating step for an extended period of time. The thermal efficiency has been improved better than with the bench furnace as a result of upscaling effect. 9 figs., 3 tabs.

In fiscal 1974, analysis was made on the concept design of solar furnace hardware, and utilization and use purpose of solar furnaces as high-temperature industrial heat source. Detailed survey was also made on the history of high- temperature solar furnaces. Based on the history of large- scale solar furnaces and the current state of some industries consuming a large amount of thermal energy, wide consideration was made on the applicability of large-scale solar furnaces as heat source in the future. Although various applications of large-scale solar furnaces are expected in the future, their current main applications are production of high-melting point materials, research on high-temperature physical properties, production of silicon, and solar heat power generation. A solar furnace is mainly composed of a parabolic reflector and heliostat plane reflector as optical system. It is necessary for practical industrial use of solar furnaces to study on furnace core design, profitability, installation site, temperature control, and reflector maintenance enough. (NEDO)

To cope with the energy issue and global environmental issue, it is necessary to forcibly promote energy conservation. In the light of the present situation that in Japan only 1/3 of the primary energy consumed is effectively used, policies are being prepared for promotion of the introduction of high efficiency thermal utilization systems including `a project for formation of the environmentally friendly type energy community` promoted by NEDO. However, it is hard to say that the introduction is being actively promoted. The cause is that they do not fully understood the present status of high efficiency thermal utilization systems, procedures for introduction, subsidy system, etc. Therefore, a manual was made to present to self governments and enterprisers who are planning to introduce the system. To be concrete, there are the six systems: cogeneration use thermal supply system, unused energy use thermal supply system, heat storage use thermal supply system, waste use thermal supply system, plant surplus energy use thermal supply system, and cascade type thermal supply system. 28 refs., 38 figs., 42 tabs.

Studies have been made about a heat accumulation tank type cooling system making use of radiation cooling that is a kind of natural energy. The daily operating cycle of the cooling system is described below. A heat pump air conditioner performs cooling during the daytime and the exhaust heat is stored in a latent heat accumulation tank; the heat is then used for the bath and tapwater in the evening; at night radiation cooling is utilized to remove the heat remnant in the tank for the solidification of the phase change material (PCM); the solidified PCM serves as the cold heat source for the heat pump air conditioner to perform cooling. The new system decelerates urban area warming because it emits the cooler-generated waste heat not into the atmosphere but into space taking advantage of radiation cooling. Again, the cooler-generated waste heat may be utilized for energy saving and power levelling. For the examination of nighttime radiation cooling characteristics, CaCl2-5H2O and Na2HPO4-12H2O were tested as the PCM. Water was used as the heating medium. In the case of a PCM high in latent heat capacity, some work has to be done for insuring sufficient heat exchange for it by, for instance, rendering the flow rate low. The coefficient of performance of the system discussed here is three times higher than that of the air-cooled type heat pump system. 8 refs., 5 figs., 4 tabs.

This paper introduces two out of six theses related to hydrogen fueled aircraft engines presented at the First World Hydrogen Energy Conference held in Miami in March 1976. One thesis mentions several initial prospects related to terrestrial requirements on hydrogen fueled transport aircraft. Liquefied hydrogen is attractive for large long-distance transport aircraft. Its high energy content can reduce the take-off full load weight by more than 30%, enhancing the economic effect of the aircraft. Saving fossil fuels will require national policy decisions in the near future, where introduction of liquefied hydrogen is more advantageous for long-distance aircraft. However, its introduction into wide-body transport aircraft being the major consumer requires transportation companies and airport authorities to carry out joint development with transport aircraft makers and liquefied hydrogen suppliers. The second thesis describes special natures of fuel subsystems for liquefied hydrogen fueled aircraft. Requirements to major fuel system elements and operation characteristics require evaluation as a comprehensive system, rather than as individual component criteria. In addition, hardware, experience and fuel systems as they are now in space development may not necessarily serve for the purpose. (NEDO)

This paper reports the study results on the standard weather data necessary for simulation of PV power generation systems in fiscal 1994. In the study on the selection criterion of the standard weather data from the viewpoint of PV power generation systems, three typical years are used; a year with average solar radiation, and two years with extremely less and more solar radiation for safe simulation. The standard weather data are arranged for output calculation of PV power generation systems by selecting the most typical year based on long-term observation data. The data to be arranged are as follows; total, direct and scattered solar radiations incident upon a horizontal surface, solar radiation upon a slope surface, sunshine duration, air temperature, wind direction, wind velocity, amount of precipitation, and snow depth. For arrangement of the nationwide standard weather data, estimation of total solar radiation is necessary based on sunshine duration data observed by all weather bureaus. In this study, the estimation model was developed of the total solar radiation integrated with time from rotary pyrheliometer data. 5 figs.

This paper describes comprehensive discussion on hydrogen utilizing subsystems. Hydrogen combustion is characterized by how low the ignition energy is, and how fast the flame propagates. In addition, flame stability is high also in diffusion combustion. However, the diffusion combustion produces a great amount of NOx, the amount varying depending on the degree of air pre-mixture. Since it causes reverse ignition very easily in the pre-mixture degree corresponding to low NOx zone, development of a burner with drastically new mechanism is demanded. In hydrogen fuel cells, the ratio of hydrogen fuel cost accounting for in the power generation cost is very high. As an automobile fuel, very much leaner combustion is possible than in conventional internal combustion engines, and ignition energy is small. However, such abnormal combustion as reverse ignition and early ignition may occur, and their prevention is an important assignment. Issues in aircraft engines are verification of safety, and cost of liquefied hydrogen. Steam turbines have reached their limit already, but gas turbines are expected of exciting efficiency improvement. This paper describes prospects on chemical utilization of hydrogen in the existing fields and new fields. (NEDO)

From the sonic prospecting on the ground, it was confirmed that faults distributed in the inner part of Suruga Bay extend near the Fujigawa river mouth. While, faults in the sea bottom were found by the sonic prospecting using a single air-gun. However, continuity of faults running from the land to the sea has not been reported. This paper describes the continuity of Fujigawa fault system running from the land to the sea around Fujigawa river mouth along the subduction zone of Philippine Sea Plate using single air-gun seismic reflection records. Locations of the faults can be expressed as fracture information of linearment obtained from the satellite remote sensing images, which agreed well with those found by the Active Fault Research Association. As a result of the image processing, they agreed distinctly with the topography of Fujigawa fault system. Thus, much more accurate analysis can be performed by comparing the regional information by the remote sensing with the sonic seismic reflection profiles. 3 refs., 2 figs.

Efforts are made under this project to develop a wastewater treatment/regeneration system, easy to operate and maintain and low in cost, jointly with a Philippine research institute. Technologies are transferred to this institute concerning research and development, system designing, operation, maintenance, and management. The goal is to disseminate such technologies in the Philippines. As for fiscal 1999 endeavors, emphases are placed on the items described below. The Container Corporation which regenerates waste paper and the RAM Food Corporation which manufactures canned foods and pickles are selected as the sites for pilot plant research. Wastewater discharged by the two corporations is subjected to laboratory-scale wastewater treatment (combination of aerobic/anaerobic treatment and activated carbon adsorption), by which a pilot plant wastewater treatment process is determined and designing conditions are defined. As for activated carbon for advanced wastewater treatment, a fine grain sample, which is the lowest in price among activated coconut shell charcoals produced in the Philippines, is acquired, and tested for performance. A wastewater treatment pilot plant is complete at the Container Corporation, and has started operation. (NEDO)

The paper investigated and studied the present situation and future trend of coal utilization and distribution in Thailand, and the present situation of environmental effects and the measures taken for environmental protection. Around 2010, coal will probably be produced only at EGAT`s Mae Moh (MM) coal mine. Demand for overseas coal is expected to be 40-50 million tons in 2011, and preparation of the coal center becomes a subject. For general industry use coal, pretreatment such as coal preparation, coal blending and briquetting is needed, considering coal quality, usage, transport distance and environmental effects. Brown coal of MM coal mine is a lignite with high sulfur, high ash content and low heating value. Wide spread of its use can be expected if upgrading is possible such as desulfurization, deashing, increasing heating value. In the electric power generation field, the absorber was installed at the existing boiler of the mine-mouth generating plant to conduct a verification test on high grade desulfurization of ultra-high sulfur lignite. In the industry field, the circulating fluidized bed boiler was adopted. In the residential/commercial field, introduction of briquette was proposed. 80 refs., 84 tabs.

In recent years, a system has been proposed that utilizes river heat, air-heat, exhaust heat from a cooler, etc., in addition to natural energy for the heat pump. With the introduction of such system, the amount of energy used and that of CO2 exhaust will be greatly reduced, but annual expenses will be increased as it stands. In order to improve the cost efficiency of the system, a proposal has been made for the introduction of an economic policy such as the carbon tax and a low interest financing system. With these matters in the background, the subject study predicts the production of solar cells in the future and, on the basis of this production, determines the price, conversion efficiency and equipment energy of solar cells in the future. Using these values and taking into consideration the introduction of the carbon tax and the low interest financing system, the optimum area was determined for solar cells and heat concentrators in a future residential solar/air-heat energy system. The carbon tax, being imposed on all CO2 discharges, had a large effect. Moreover, as the tax increased, annual expenses decreased for the solar/air-heat system. 3 refs., 6 figs.

This paper reports the study results on R and D of nickel-hydride storage battery for photovoltaic generation systems in fiscal 1994. (1) On the study on low-cost electrode materials, the physical properties and electrode characteristics were studied of the prototype hydrogen absorbing alloys prepared by substituting Cu or Ni for Co in Mm(Ni-Co-Mn-Al)5 (Mm: mixture of rare earth elements). The result clarified that it is difficult to reduce Co content in the alloy to 0.4 atom or less. Simple heat treatment and milling processes in production of hydrogen absorbing alloy electrodes were achieved by adopting an improved metal mold and gas atomization method. Characteristics and cycle life of the Ni positive electrode prepared by applying active paste material of Ni(OH)2 were studied, however, the result showed only lives of nearly 300 cycles. (2) On the study on electrode structure for high-performance (long-life) battery, the 3-D porous metal electrode support was evaluated, and various battery configurations were studied. 11 figs., 1 tab.

Described herein are the results of the FY1994 research program for analysis and evaluation of new storage batteries for photovoltaic power systems. Quantitative analysis and evaluation are made for introduction of intermittent operational mode in the conventional power supply system in which electrolyte units are connected in parallel and for improved performance by bubbles flowing into the line that supplies the electrolyte to the stack, in order to establish the configurations of and operational procedures for the redox flow batteries. The study on development of redox battery compares the Pb-Sn alloy felt collector with carbon fiber, Pb-Sb alloy felt and the lattice for the conventional lead acid battery, in order to optimize the new lead felt battery. As a result, it is found that the Pb-Sn alloy felt collector is better than any other device tested, because of its higher freedom with respect to electrode shape and battery size. The study on reliability evaluation of amorphous solar cells tests photoelectric conversion efficiency of a-Si solar cells, in order to elucidate the phenomena where degradation and rejuvenation compete with each other under weak light irradiation conditions. 8 figs., 1 tab.

The paper surveyed the present situation and future trend of economy, energy supply/demand, coal production/distribution/utilization and the environmental effects in Thailand. The survey on the coal utilization and its environmental effects was partially requested of the environmental research institute in Thailand. The amount of coal utilization in Thailand rapidly increased to nearly four times as large as that ten years ago mainly in terms of domestic lignite under the government`s policy on expansion of the domestic energy use. However, most of this domestic lignite is low-grade coal with low calories and high sulfur content, and the use of it was rapidly increased mostly in power generation sector without no adequate environmental measures taken. This caused an environmental problem on air pollution due to sulfur oxides at Mae Moh power plant in the north several years ago, and the damages to the regional residents, etc. were given much publicity by journalism and developed the social problem. Accordingly, Thai people are now critical of the coal resource exploration and the coal use expansion. Under the circumstances, the Ministry of Industry and the energy related ministries/offices are obliged to review their development/promotion plans. 84 figs., 99 tabs.

This paper discusses hydrogen fueled automotive engines. Because hydrogen has a very wide ignition mixture ratio limit for spark ignition engines, very lean combustion is possible without a need of throttling, and thermal efficiency in partial load is high. Thermal efficiency while a car is being driven is reportedly higher by 30% to 50%. Values for CO and CH in exhaust gas are negligible, while NOx is at about the same degree as in gasoline engines, which can be made extremely low during lean burn operation. The spontaneous ignition temperature is higher by about 200 degrees C than that of light oil, which presents difficulty in use for diesel engines. Because of small ignition energy and high combustion velocity, excessively early ignition and reverse ignition can occur easily. Hydrogen would be promising if new manufacturing systems are developed and production cost is reduced, and on the other hand, if petroleum price rises sharply. Hydrogen is also expected as a measure to prevent pollution, including that from soot, odor and CO2. The largest difficulty is in the transportation method, and the only possible method at the present is transportation in liquefied hydrogen form. However, practical application will have such problems as tanks, feeding devices, and cost. Development is desired on light-weight metallic hydrides. Technologies for safety and engine performance must also be developed. (NEDO)

The coal cartridge system (CCS) is a series of the total system, in which coal is processed centrally at a supply base for each unit of consumer areas, supplied as pulverized coal in bulk units, and coal ash after combustion is recovered and treated. The system is expected of advantages resulted from the centralized production, elimination of handling troubles, and cleanliness. Following a small scale demonstration test, a large demonstration test for practically usable scale has begun in 1990, and completed in fiscal 1995. This paper introduces the CCS and reports the result of the test. In the large demonstration test, a supply station (with manufacturing capability of 200,000 tons a year) was installed in the Aichi refinery of Idemitsu Kosan Co., Ltd., and systematization on quality design and system technologies has been carried out. Long-term continuous operation for five years was achieved (operation time of the supply facilities was about 19,000 hours) without a failure and accident, to which every elemental technology was evaluated highly, and convenience and reliability of the system was verified. 13 figs., 3 tabs.

Large scale and effective utilization of renewable energy including hydroelectric power, photovoltaic power, and wind power which are abundant on the earth can contribute to the solution of global environmental issues as well as the release of energy demand and supply. Hydrogen can be produced from the renewable energy, and is converted, transferred and stored if necessary. Such hydrogen can be used in various fields for power generation, fuel for transport, and city gas. In order to establish the technology by which worldwide energy network can be introduced for wide range of fields, conceptual design of a total system has been conducted, and elemental core technologies have been developed. Conceptual design of a practical scale system (total system) including a wide range from production of hydrogen to its utilization has been conducted, and its constitution has been illustrated. In addition, the energy balance and cost of hydrogen have been calculated and analyzed as a trial. Hydrogen production technology, transport and storage technology, and hydrogen utilization technology are introduced as individual elemental technologies. Research results of innovative and leading technologies obtained in FY 1996 are reviewed. 80 figs., 56 tabs.

With the aim of formulating a strategy for introducing hydrogen, assessment was carried out on the energy consumption, environmental impacts and cost effiectiveness concerning various hydrogen utilization systems. In regard to soda-electrolysis by-product hydrogen and coke-oven by-product hydrogen, hydrogen supply capacity and cost effectiveness were evaluated. As a result, the two systems were found to have an annual hydrogen supply capacity of 11.52 GNm{sup 3} in total. As to the cost effectiveness, transportation by pipeline was 34 yen/Nm{sup 3}-H{sub 2} in the case of soda-electrolysis by-product hydrogen, and 40 yen/Nm{sup 3}-H{sub 2} in the case of coke-oven by-product hydrogen. An estimated cost of power generation showed 56 yen to 67 yen/kWh in such a system on remote islands as replacing diesel power generation by wind power generation, storing part of the electric energy produced in the form of hydrogen through water electrolysis, and using it as fuel for power generation by the fuel cell unit if wind conditions are unfavorable. Power generation cost on remote islands at present is sometimes in excess of 50 yen/kWh; therefore, this combined system showed promising results.

For the purpose of the improvement of coal utilization technology and environmental preservation, the paper conducted the pre-survey of the introduction of coke oven gas desulfurization facilities in China and pre-survey of potentiality of the environmentally friendly type coal utilization system in India. The pre-survey in China was made for Anyang Steel Group Co. Ltd. and Laiwu Steel Group Co. Ltd. to judge their adaptability as site for the demonstrative project on the introduction of coke oven gas desulfurization facilities. As a result, it was confirmed that the former satisfied the conditions on Japan side such as the space for installation and prospect for fund raising. However, the amount of COG treatment was larger than that planned at Japan side, and it was found that as to the recovered sulfur, the company wanted the solid sulfur different from the fused sulfur planned at Japan side. In the survey in India, explanations were made to India of CFBC and the fluidized bed cement sintering system, bio-briquette production facilities, facilities for environmental measures, coal reforming technology, etc. At the same time, the site survey was made to examine/analyze possibilities of spread/development of Japan's CCT.

This paper reports the result obtained during fiscal 1994 on a survey to prepare scenario for the diffusion of photovoltaic power generating systems. Introduction target planned with help of a diffusion simulation was verified by calculations using simulation models. The calculations made the following points clear: facility costs and power generation costs for photovoltaic power generation systems, amount of introduced photovoltaic power generation systems, number of facilities introducing photovoltaic power generation systems, policy cost to achieve the target, annual power generation amount, oil substituting effect, carbon dioxide reducing effect, and market sizes. Power generation cost in fiscal 2000 would drop down to 53 yen per kWh in new installation in independent houses and down to 31 yen per kWh in systems used in schools. These reductions are the result of progress in mass production as a result of positively implementing the aiding policies. The required diffusion aiding policies revealed from the simulation results include expansion of subsidy operations for house construction, introduction of the systems into public facilities performed by public organizations, aid to system introduction into private business entities, subsidy to facility investments, and enforcement of power purchase institutions. 3 figs.

The research is conducted in cooperation with Industrial Technology Development Institute of the Philippines, and aims to solve water related problems such as unstable water supply and water quality pollution though developing a waste water treatment and recycling system which is easy to operate and maintain, low in cost, and usable in the Philippines. Fiscal 1998 is the second year of the project. Statistics are studied about the load that each industrial branch imposes on water for its pollution, and it is found that food manufacturers, paper pulp mills, and fiber dyeing plants are heavily responsible for water pollution. A method consisting of single-tower UASB anaerobic treatment and activated sludge treatment is applied as a water treatment process to Ram Food Products Corporation, and its optimization is studied. A removal rate 60% is achieved after a 12-hour treatment period at a COD (chemical oxygen demand) rate of 8g/liter/day. A method consisting of coagulating sedimentation and activated sludge treatment is applied to the waste water from a Solid Mill Corporation dyeing plant, when it is found that the water after ultimate treatment is almost colorless and that COD is 76mg/liter and BOD (biological oxygen demand) 13mg/liter, and these suggest that the waste water is recyclable. Since it is low in COD removing rate, the application of anaerobic treatment to high-concentration water after washing is not appropriate. (NEDO)

For the purpose of prevention of water pollution, stable water supply in the Philippines, etc., developmental study was made of a waste water treatment/water recycling system, and the FY 2000 results were summed up. In the operational study of Pilot Plant 1, for the waste water in the papermaking process of used paper recycling plant, development was studied of a waste water treatment/water recycling system. There occurred problems on minuteness, outflow, etc. of anaerobic granules, but those were caused by malfunction of SS removal equipment at plant side. The problems were solved by increasing flocculation/precipitation facilities. As to Pilot Plant 2 of which the R and D are planned to be started in April 2001, the food processing plant was surveyed for study, and SYSCORE was selected. Relating to the waste water treatment test of Pilot Plant 2, researchers of the Industrial Technology Development Institute (ITDI) of the Philippines conducted it under the guidance of the experimental data analysis. Besides, the paper carried out the training for technology spread/acceptance, technology spread seminar, support study in Japan, etc. (NEDO)

Researches were conducted for the goal of proposing a totally new process enhanced in efficiency and energy saving, and capable of CO2 separation. In fiscal 1997, hydrocarbon materials were reformed by oxygen separated within a system allowing fuel cells to generate power efficiently, when all the emitted CO2 was separated and recovered within the system. Furthermore, cold heat was utilized for the acquisition of liquefied CO2 gas products. A part of oxygen separated at the fuel cell cathode was recycled into the combustion section external to the tubular reaction reformer, and CO2 was separated by mere cooling from the combustion products for the simultaneous production of by-products such as high-purity nitrogen gas and liquefied CO2 for a great improvement in economy. In fiscal 1998, the system was improved. Proposed then was a new system in which an oxygen partial oxidation type reformer assumed the nuclear role, separating all the oxygen at the cathode, reusing part thereof for oxygen enrichment, and feeding the rest thereof into the reformer. The design realized the recycling of the whole of the products of the two cell electrodes into the reformer for the maximum reuse of the products of the hydrogen/oxygen separation function. (NEDO)

The paper studied a solar heating system with thermal core type soil heat storage (combining a thermal core composing of a water tank and an underground pebble tank and the soil around the heat storage tank and also using solar energy). Solar energy is stored by temperature level in the high temperature water tank, the low temperature pebble heat storage tank and the soil around the heat storage tank. Heat is recovered according to temperature as direct ventilation space heating (utilization of pebble tank air), floor heating (utilization of hot water of the heat storage water tank) and heat pump heat source (utilization of pebble tank air). A study was made of performance and regional effectiveness of the system under different weather conditions. A study was also made of effects of the water tank for short term heat storage by changing the water volume. Using the same structure, etc. for the system, the system was evaluated using weather data of Sapporo, Tokyo and Kagoshima. In terms of efficiency of the system, the system structure was found to be most suitable for weather conditions in Tokyo. However, the air heat source heat pump which cannot be usually used in the cold area has come to be used. Such effect except efficiency is also considered, and the amount of performance to be targeted in each region changes. 2 refs., 14 figs., 1 tab.

Polders have no basin of their own, and the supply of irrigation water in polders is always short and unstable. The irrigation water system is so structured that the conflicting objects of both the insurance of irrigation water and drainage of rainwater can be achieved. Quoting an example at the surrounding area of the Kojima Bay in the southern area of Okayaja Prefecture where inning (land reclamation by drainage) has been practiced for a long time, problems in drainage improvement required for better use of low-lying flat lands are discussed. There are complicate relations among the safety against flood, rainwater drainage capability, stock capacity, and critical leveling time, therefore, the basic operation which must be performed at first in making a drainage plan is to determine the basic framework of the plan taking those relations into consideration. In low-lying flat lands, safety of the total area against flood has been established basing on the stock capacity of the paddy fields, and it is important to secure paddy field areas to a certain extent. 8 refs., 7 figs., 1 tab.

This paper reports the survey results on evaluation of PV power generation in fiscal 1994. (1) On the evaluation technique of energy pay-back time, foreign trial calculation examples by integration method were surveyed. However, there were not many study examples, and the calculation basis of input energy was also ambiguous. The calculation result by input-output analysis in Japan gave the value more than that by integration method, pointing out that indirect input energy is essential. (2) On the evaluation technique of the degree of environmental contribution, CO2 emission of the PV generation system installed on ordinary housing roofs was calculated to estimate reduction of CO2 emission and cost. As a result, PV power generation as reduction measures against CO2 brought a little cost increase. (3) On the latent scale of PV power generation, it was estimated to be nearly 191GW although under no restriction. It was a considerably large value as compared with the current power generation capacity in Japan. 4 tabs.

As carbon dioxide-related environmental measures, method was explained to chemically convert and utilize carbon dioxide. Synthesis is possible of methanol, carbon monoxide, different carbohydrates, etc. by catalytic hydrogenation of carbon dioxide, using hydrogen produced by the electrolysis of water. Task consists of heightening in both convertibility and selectivity, and abundant supply of low cost hydrogen. Methane, alcohol, etc. can be synthesized by electrochemical reducion of carbon dioxide. Because of effectively inserting multiple electron, discssion is being made of catalyst, intergrated with electrode, and electron transmitter. The photoelectrochemical reduction of carbon dioxide can be also made by utilizing photoelectric current, generated upon photoradiation on the semiconductive electrode. However, task consists of heightening in both efficiency and selectivity. Photochemical reduction of carbon dioxide, actually made by green plant, consists of oxidationlike decomposition of water and reduction of carbon dioxide. Both those reactions are skillfully separated by intermediation of very quick electron transmission system. Reduction is being studied with semiconductor, metallic colloid, enzyme, metallic complex and other various catalysts. 10 refs., 3 figs., 4 tabs.

This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-5, the development of a hydrogen fueled automobile system. For a fast filling method using a hydrogen absorbing alloy as the fuel tank, a rare earth system, the Laves system, and a body-centered cubic system were selected to discuss filling time when the plate-fin system tank and the divided system tank are used. Either system was found capable of filling 80% of the effective hydrogen absorbing amount within 10 minutes, having achieved the target. Guidelines were obtained for the design aiding method by using the cooling water flow rates, temperatures, and simulations. In the safety assessment, even the spontaneously combusting alloy of Category 1 in the Fire Fighting Law did not cause ignition even if the tank was damaged and the alloy was discharged in the dropping/falling weight tests. It was inferred that the ignition temperature is not reached because of the self-cooling made when hydrogen is discharged from the alloy. In the fire resistance test, the tank temperature was found not to rise as long as hydrogen is discharged from the alloy. Since the temperature rise and damage could occur if the discharge has been finished completely, discussions are required on materials and the soluble plug. Deformation may occur in the initial stage of the hydrogen absorbing and discharging cycles, but it would not occur after 5,000 cycles. (NEDO)

For the effective utilization of solar energy at houses, a heating system using an air hybrid collector (capable of simultaneously performing heat collection and photovoltaic power generation). As the specimen house, a wooden house of a total floor area of 120m{sup 2} was simulated. Collected air is fanned into a crushed stone heat accumulator (capable of storing one day`s collection) or into a living room. The output of solar cell arrays is put into a heat pump (capable of handling a maximum hourly load of 36,327kJ/h) via an inverter so as to drive the fan (corresponding to average insolation on the heat collecting plate of 10.7MJ/hm{sup 2} and heat collecting efficiency of 40%), and shortage in power if any is supplied from the system interconnection. A hybrid collector, as compared with the conventional air collector, is lower in thermal efficiency but the merit that it exhibits with respect to power generation is far greater than what is needed to counterbalance the demerit. When the hybrid system is in heating operation, there is an ideal heat cycle of collection, accumulation, and radiation when the load is light, but the balance between accumulation and radiation is disturbed when the load is heavy. 4 refs., 8 figs., 3 tabs.

Observations are being made in Takasaki City, Gunma Prefecture on insolation, putting emphasis on the north side, and insolation by wavelengths to put insolation estimation model on the north side slope into order. This is an attempt to put into order by using the model the data for insolation on slope in all azimuth, taking the meteorological offices all over the country as the object. With regard to monthly average insolation, it was verified that the existing estimation model can be applied to the north slope in the Takasaki area, whereas trial calculations were performed on the average daily cumulative insolation by azimuth and inclination angle in the Takasaki observation points. As a result, it was made clear that the insolation onto north side roofs in Japan is about 70% of that on the south side. With respect to the time cumulative slope insolation, it was made clear that the Perez's cumulative model can be applied to the Takasaki area. Spectral distribution of global and scattered solar radiation was put into order by insolation to have verified that the stronger the global solar radiation intensity, the greater the occupation ratio of shorter waves increases, or in other words, the spectral distribution of the global insolation can be formulated. Sky distribution of radiation is being measured by means of measuring the sky scanning type radiation and luminance distribution. (NEDO)

A study was made of the periodic steady state of the annual cycle solar energy system with seasonal heat storage at a practical operation. Cold heat in winter and warm heat in summer are stored in the seasonal storage tank, and these are each used in shift until when demand for cold/warm heat appears. Moreover, gap in quantity of cold/warm heat going in/out of the heat storage tank during a year is filled by natural energy such as solar energy, so that the system can be operated in annual cycles. Studies were conducted of the periodic unsteady term and the problem on lowering of performance during the term such as the periodic unsteady term of water temperature inside the seasonal heat storage tank and temperature of the soil around the storage tank, and the level of lowering of performance during the term, necessity of additional operation/control at the start of operation and aged deterioration of the system. Within the assumption, even if starting operation in any time of the year, the system could show the performance almost expected from the first operation year with no additional system operation and control required only at the start of operation. It is thought that the heat source selection control of heat pump largely contributes to this. 4 refs., 5 figs., 3 tabs.

Described herein are the results of the FY1994 research program for international joint technology development for solar energy utilization systems. The joint study with an Indonesian research institute takes a model of lumber drying plant for the design and feasibility study. All the parts it needs are technically available in Indonesia, except carbon fiber sheets and electronic devices for controlling purposes. The drying cost is higher than that of a plant which procures charge-free wood fuel, but lower than that of a plant which procures fuel at 30$/t. A cacao drying plant model is also studied. The feasibility study shows that the initial investment for the blowing-up model is much higher by 60% to 100% than that for the conventional plant. Its fuel cost is lower by 11% than that of residual oil but 27% higher than that of wood. 4 figs.

An airborne gamma-ray survey was carried out to investigate the active fault system in the central structure line in the peripheral area of the city of Wakayama. At the same time, with an objective to enhance applicability of the airborne gamma-ray survey to active fault investigation, fundamental data were acquired and discussed. The measurement data were processed according to the standard method specified by IAEA. An ID-FFT filter and a nonlinear filter were employed to extract anomalous gamma-ray intensity values. The gamma-ray intensity distribution chart shows a noticeable positive anomalous area extending from the central part of the western edge to the north-east direction. This area agrees nearly well with the Negoro fault, but its peak portion is positioned slightly more to south than the position of the Negoro fault shown in existing data. The Sakuraike fault and the vicinity of the central structure line also show positive anomaly as a whole, particularly remarkably in the vicinity of their converging portion. However, differing from the vicinity of the Negoro fault, the areas are not extracted as an anomalous area which has directionality and extends in a line form. One of the factors for this would be that it is a fault in unsolidified deposits with low opening trend, differing from the one in solidified rocks. 1 fig., 3 tabs.

The recovered gas is to be supplied to the cities of Tiefa and Tieling as town gas, for which compressed gas feeding and controlling technologies and facilities will be introduced. This paper lists the gush-out quantity (1,000 Nm{sup 3}), the recovery quantity (1,000 Nm{sup 3}), the recovered gas concentration (%), the utilization quantity (1,000 Nm{sup 3}), and the utilization rate (%). The figures for the respective items before and after the implementation are 128366, 32949, 44.5, 7000, 5, 123500, 43890, 49.1, 39826, and 32. The quantity of gas gushing out at facings decreases in association with increase in the recovered gas quantity, whereas the gas concentration at facings in the Daixing mine in 2003 is estimated to decrease to 0.1%, contributing to safe mining operation. The test drilling for medium measure horizontal degassing expands the degassing assured scope per one test drilling seat, and can reduce the total test drilling length and construction amount.

This paper introduces the polymer dispersed liquid crystal (PDLC) ACT'' sheet, a liquid quartz light modulating film, developed by the Ajinomoto Company in Japan. A mixture of liquid crystal and polymer precursor is sandwiched between polyethylene terephthalate films imparted with transparency conductor made of indium tin oxide (ITO), which is then polymerized by heating or irradiating ultraviolet rays to obtain a PDLC. The film has a thickness as thin as about 0.3 mm, and good processibility. The sheet uses light modulating elements functioning on scatter and permeation of light. Clarification was made on the voltage dependence of cloudiness, total light permeability, straight and parallel light permeability, the response, and the operating voltage. The system consumes small amount of power with a threshold value of about 35V, and is suitable to operate large areas when working on the utility power supply. An incident light having a high diffusion capability when the electric field is turned off exhibits a high clouding function. The system gives an excellent feel of colorlessness and transparency when the electric field is turned on. The performances in heat insulation, infrared reflection capability and noise resistance are expected to be compounded for a functional versatility. 4 refs., 6 figs., 2 tabs.

As a research on systematizing ECO and ENERGY cities, surveys and analyses were performed on the actual state of introducing district heat supply systems utilizing difference waste heats including factory waste heat. Waste heat from electric power generation is utilized for district heat supply in Japan at 122 points or about 20% of the district heat supply points in operation as of March 1998. The number is in the increasing trend in recent years, and the future potential of its introduction can be said high as the history thereof is still short. Its introduction form is accounted mostly for by building cogeneration or plant cogeneration. Back-up facilities for the case when waste heat supply stops because of regular facility checks are provided by the heat supply business operators, which impede the economy of the system. In the U.S., the Public Utility Regulatory Policy act motivated installation of cogeneration and off-peak power generation systems for district heat supply. Technical maps (for waste heat sources and different waste heat utilization systems) were prepared based on the surveys to discuss the future measures. (NEDO)

Technology development was conducted for production of useful substances using the bioconsortia system. In FY 1998, the development of element technology was studied. As to the utilization technology of gut symbiotic microorganisms such as termite and longhorn beetle, clone types of gut microorganism complex system were analyzed to find out the diversification. In the decay of wood, co-culture of two species of mold fungus was increased in efficiency than single culture. More than 90% was classified/identified of the mold fungi accumulated (in wood piece)/separated for the utilization of plant symbiotic microorganisms. For the production of petroleum substituting useful resource, conditions were established of callus induction from immature embryos of tropical oil crops, especially oil palm, and of regeneration of a lot of small plants from the callus. To establish the Agrobacterium-mediated transformation system of oil palm, the binary vector harboring the reporter gene and selectable marker gene was constructed. Using the vector, oil palm tissues are inoculated and infected with agrobacteria. To heighten the function of palm oil, 10 particular clones were selected from the complementary DNA library obtained from oil palm fruit tissues. The genetic study of germs was also made. (NEDO)

This paper describes development of hydrogen production technology as a part of the WE-NET project. For the solid polymer water electrolysis method higher in efficiency and lower in cost than the previous methods, 5 companies have developed element technologies for improving electrolysis cells and synthesis technologies of hot solid polymer electrolyte based on each proper catalyst electrode production method. In fiscal 1996, the initial study on large-scale systems by middle laboratory cells was made as well as improvement of electrolysis performance by small laboratory cells and endurance tests. Among the previous methods such as a hot press method (bonding of an ion exchange membrane to an electrode), an electroless plating method (preparation of porous surface onto a membrane electrode assembly), a zero gap method (preparation of high-efficiency high-current density cells), and a sintered porous electrode method (carrying of the mixture of catalytic powder and ion exchange resin-dissipated solution onto sintered metallic porous electrode surface), the former two methods were adopted for development of bench-scale cells as effective promising methods. 192 refs., 183 figs., 108 tabs.

Practical application of subsurface crack characterization by the borehole radar measurement to which the radar polarimetric method was introduced was attempted to measuring objects for which the borehole radar has not been much used, for example, the inside of low loss rock mass or fracture zone where cracks tightly exist. A system was trially manufactured which makes the radar polarimetric measurement possible in the borehole at a 1000m depth and with a about 10cm diameter, and a field experiment was conducted for realizing the subsurface crack characterization near the Nojima fault. For the measuring experiment by the polarimetric borehole radar, used were Iwaya borehole and Hirabayashi borehole drilled in the north of Awaji-shima, Hyogo-ken. In a comparison of both polarization systems of Hirabayashi borehole, reflected waves at depths of 1038m and 1047m are relatively stronger in both polarization systems than those with the same polarization form and at different depths, whereas reflected waves around a 1017m depth are strong only as to the parallel polarization system. Characteristics of the polarization in this experiment indirectly reflect crack structures. 6 refs., 6 figs., 1 tab.

This paper summarizes materials for aircraft engines. Jet engines are the mainstream today, which are classified according to their operation process into a turbo jet engine, a turbo prop engine, a turbo shaft engine, and a turbo fan engine. Japan has produced 1543 engines in the past decade, almost all of which are supplied to the Defense Agency. Jet engines use mainly Ni-group heat-resistant alloys, titanium alloys and steels. Improvement of engine efficiency has caused turbine inlet temperatures to rise to 1400[degree]C to 1500[degree]C that give rise to grain boundary cracking. To prevent this, discussions are in progress on monocrystal blades replacing the conventional polycrystal precision casts. Intermetallic compounds including Al/Ti are expected especially of use as jet engine constructing materials from their high melting point and formability. Discussions are preceding on ceramics as to coating them intended of improving heat resistance. Composite materials have a problem of insufficient mechanical strength remaining unsolved. 8 figs., 5 tabs.

In this study, taking the all factors involved in the energy consumption in residential houses as subjects, the effectiveness of the solar PV system and solar thermal utilizing system in residential houses has been studied by simulating a model residential house considering the improvement of the residual environment in the future. Therefore, a model residual house is assumed, 18 kinds of combinations of construction style, cooling and heating type and solar energy utilizing form are assumed and year round simulation is carried out. The conclusions obtained by the simulation are as follows. The energy consumption in residential houses may decrease greatly by using a solar hot water supplying system. If combined with a solar PV system, the energy consumption in one year is about 8.7 to 9.7 MWh. The combined use of a solar thermal utilizing system and a PV system is more effective to reduce the second-time energy in comparison with the PV system only. 36% of the space heating energy consumption may be decreased by using the solar space heating system, but the decrease effect of the energy consumption of the solar space heating system is smaller than the solar hot water supplying system. 12 refs., 26 figs., 3 tabs.

The paper made an investigational study of the data of a wide range which seems to be related to the use of hydrogen as automobile use fuel. The advantage is that the exhaust can almost be non-pollutant. The engine performance can be on the same level as that of the present gasoline engine or can be improved. The reasons are that the compression rate is heightened and that automobile can be driven at lean mixture rate. As to weak points, the volume and weight increase when it is loaded on vehicle. The cost of hydrogen is higher than that of petroleum. The problems to be quickly solved are as follows. Improvement of the combustion method: a wide range of development not only the electric ignition method, but the diesel method, and the basic study for it. It is necessary to establish the basis for a method to connect the storage method and engine. It is also necessary to comprehensively review rules related to safety. For the future, the conversion to artificial fuel is indispensable, and hydrogen has the most characteristics as energy medium. The problem is much larger sizes of fuel tank and pump, but there will be a possibility of producing a new technology together with the hydrogen production technology. The fundamental research should be promoted without any hesitation. (translated by NEDO)

The coal utilization is expected to make substantial growth according to the long-term energy supply/demand plan. To further expand the future coal utilization, however, it is indispensable to reduce environmental loads in its total use with other energies, based on the coal use. In this survey, a regional model survey was conducted as environmental load reduction measures using highly cleaned coal which were taken in fiscal 1993 and 1994. Concretely, a model system was assumed which combined facilities for mixed combustion with coal and other energy (hull, bagasse, waste, etc.) and facilities for effective use of burned ash, and potential reduction in environmental loads of the model system was studied. The technology of mixed combustion between coal and other energy is still in a developmental stage with no novelties in the country. Therefore, the mixed combustion technology between coal and other energy is an important field which is very useful for the future energy supply/demand and environmental issues. 34 refs., 27 figs., 48 tabs.

This project is aimed at development of technologies for effective utilization of power produced by polymer electrolyte fuel cell (PEFC) systems and waste heat, to spread cogeneration systems incorporating PEFC systems for residential purposes. Described herein are the FY 2000 results. The program for high-efficiency peripherals for residential PFEC systems attempts use of GaN-FET as the semiconductor device of wide band gap and high breakdown voltage to realize conversion efficiency over 90% by improving inverter efficiency. Two types of the prototype heat recovery systems are developed for the PEFC, one incorporating a latent heat cooling system and the other a water cooling system, to improve heat recovery efficiency and increase heat recovery temperature. The program for technology to fit PEFC output to energy demand develops hot water supply systems provided with a hot water storage function for stable supply of hot water irrespective of the heat recovery conditions, and also with a back-up function with burners. The program also develops the PEFC system of fine load following characteristics, for which pure hydrogen is used as the fuel to allow the system to instantaneously follow fluctuating loads. The program for high-efficiency partial load operation technology studies a 1kW-class residential PEFC cogeneration system incorporating a power storage device for high-efficiency operation at partial loads, where the former operates in a high output mode while the latter absorbs fluctuating loads.

This paper describes interactions between wall rocks around magma and hot water. The paper discusses effects of hydrothermal environments on dynamic properties of rock minerals with respect to hydrolytic weakening (decrease in dynamic strength of a mineral under presence of water) and reaction enhanced deformation (deformation accelerated by chemical change occurring in a mineral itself). It also explains chemical reactivity of minerals under hydrothermal enviroments with respect to four types of chemical changes in minerals, factors governing mineral dissolution rates, and importance of equilibrium and non-equilibrium in main components in reactions between minerals and waters. These statements quote mainly results of indoor experiments. The paper indicates the following matters as problems to be discussed on interactions between wall rocks around intrusive rocks and hot waters: Deviation from chemical equilibrium in reactions between rocks and waters; change in permeability as a result of reactions between rocks and waters; and possibilities of hydrolytic weakening in rocks around intrusive rock bodies. 52 refs., 6 figs.

For the realization of urban society respecting enhanced energy efficiency and environmental protection, cities and surrounding industrial facilities are investigated for the development of element technologies involving energy recovery, conversion, transportation, storage, delivery, utilization, etc., and for the compounding of urban energy systems. In the study of the effect of introduction, assumption is made of delivery of heat to an urban heat accumulation district from a plant equivalent to a district air-conditioning system which is covered by the existing technologies. Also assumed are the delivery of exhaust heat to the said plant utilizing eco-energy element technologies and the replacement of existing technologies by eco-energy element technologies. Comparison is established in terms of energy efficiency, environmental protection, and economy, and then it is found that the eco-energy element technologies for the utilization of exhaust heat are in all cases superior to the conventional technologies as far as energy efficiency and environmental protection are concerned. It is found, however, that they are inferior from the economic viewpoint. The energy efficiency technology in heat transportation is superior to the existing technology in energy efficiency and environmental protection but roughly equal to the existing ones in economy.

The paper introduced the present situation and future task of the tackling with effective use of coal ash discharged from coal thermal power plants. Making the use of the characteristics, coal ash is mostly used in the fields of cement/concrete, civil engineering/construction, and agriculture/forestry/fisheries. In the case of using fly ash to concrete, the effects are the heightening of long-term strength, increase in workability, decrease in hydration heat, control of alkali aggregate reaction, etc. In the civil engineering/construction field, coal ash is allowed to be used for road bed material and mixed civil engineering material as road materials, for revetment back-filling material, soft ground surface layer treatment, soft ground/soil improvement materials, FGC deep layer mixing treatment process, SPC (sand compaction pile) material, etc. as earth work materials. Besides, it is used for light coarse aggregate, light sand, etc., as construction materials, for material substituting ceramics products, etc. as building materials, and for agricultural material, potassium silicate fertilizer and ocean structure in the agriculture/forestry/fisheries field. 4 refs., 2 tabs.

The solar energy utilizing technologies having been developed under the Sunshine Project were used to have executed the international joint technology development on the 'solar heat utilizing drying system' in the Republic of Indonesia. This paper summarizes the achievements in fiscal 1998. In operating the pilot plant, three operational experiments out of seven experiments were carried out only by Indonesian engineers. As a result of the drying experiments, the heat collecting characteristics of the collector were as about half at 19 to 30% as the efficiency assumed in the design of 50%. The reason for this can be attributed to the fact that the cover glass used in the demonstration test in Japan had light permeability of about 87%, but the cover glass used in the test plant was made of frosted glass whose light permeability was about 37%. This glass is the only glass available for a heat collector in the solar heat hot water device in Indonesia, but is unsuitable for the heat collector. Another cause was that the insolation at the site was lower by about 30% than the one used at the design stage. (NEDO)

The WE-NET Project is a long-term project designed to ensure that an energy network technology using hydrogen becomes a reality not later than 2020. So the project cannot remain effective unless constant efforts are made to foresee future trends of technology and optimize it as the making of entire system for the project. In this project, new technologies which are not up for development are also investigated. Their feasibility should be studied, if necessary. From the foregoing point of view, new technologies are studied, collected and evaluated. Thus, useful suggestions and proposals may be made as to the course for the project to follow, as well as its research and development. Proposals highly evaluated up to FY 1995 are the hydrogen-oxygen internal-combustion Stirling`s engine, hydrogen production by solid oxide electrolysis, magnetic refrigeration technology for liquefaction of hydrogen, solar thermal hydrogen production with iron sponge technology, and hydrogen producing technology with photocatalyst. Conceptual investigation themes in FY 1996 are the hydrogen internal-combustion Stirling engine, solar thermal hydrogen production, phototransformation process, and high-temperature steam electrolysis. 9 figs., 54 tabs.

For the realization of the cycling recycle society, it is important to promote recycling using glass waste for CO2 reduction and effective use of resources. The paper described the FY 1998 results of the development. It included the classification by which the composition of the particle sizes required for recycled products will be made possible, basic studies for low-cost pulverization/separation of foreign substances, and tests on heightening of process accuracy. Relating to the artificial synthesis of feldspar/pottery stone using glass waste/alumina waste as starting materials, vitrification behavior was studied to find out the optimum synthesis conditions. Glass waste of 60% and aluminum hydroxide of 40% were mixed at calcination temperature of 1,100 degrees C for more than 1 hour. Properties of the artificial feldspar/pottery stone were similar to those of the natural one. As to the utilization of glass waste to hydrothermally solidified materials, high-strength solidified matter without crack was obtained in the three-component system of G powder/hydrated lime/gypsum. Concerning the production of eco-glass block, a study was made on the size and mixing ratio of the cullet waste which is very soluble and has no effects on performance. The paper touched also on the R and D of the environmentally friendly type system using multi-functional hybrid materials. (NEDO)

Actualities of exhaust heat and demand for heat in the area are investigated on the result of which a wide-area energy utilization network system will be built. In fiscal 1998, further questionnaires are distributed in addition to last fiscal year's, and door-to-door visits are made on leading factories representing 10 types of industries. The result of data analysis places the nationwide total of exhaust heat at 320,000 Tcal/year including heat generated by electric power generation. When it is so defined that usable heat be above 150 degrees C for exhaust gas, above 40 degrees C for hot water, and above 200 degrees for solids, the total will be reduced to 230,000 Tcal/year. Cleaning plants (plants that treat refuse or sewage) as the sources of exhaust heat besides the factories are investigated for the amount of heat they discharge, and then it is found that the amount of heat they discharge is the fourth largest following electric power plants, iron and steel mills, and chemical plants. It is also found that most of their exhaust heat is of good quality because it is latent in steam or hot water. It is acknowledged, partly because many of such plants are situated relatively near to the urban district, that their role is important when studies are made on the utilization of exhaust heat.

At COP3 in 1997, an agreement was made to the innovative technical development/promotion by international cooperation, and the promotion of transfer of environmental technology to developing countries. Under the agreement, a feasibility study of international cooperation was made, and especially a study was conducted of the utilization/development of solar energy by the innovative solar thermochemical process. The main reason for global warming is emissions of a large amount of CO2 caused by the direct combustion of fossil fuels. Therefore, a CO2 recycle system taken up in the study enables a more substantial decline in CO2 emission (kg/kWh) per unit generation than the conventional thermal power system by composing solar methanol or solar dimethyl ether using fossil fuels including coal, water, CO2, etc. as raw materials and using solar energy as heat source, and by using this as fuel (solar fuel). CO2 can be reduced by 13% to 14% by substituting solar methanol or solar dimethyl ether produced from petroleum/methane equivalent-mol mixed raw materials for the equivalent mol coal and natural gas of the thermal power plant (CO2 recovery is not necessary). 34 refs., 47 figs., 34 tabs.

With an objective to utilize hydrogen fuel in aircraft engines, a conceptual design survey was carried out on medium size transport aircraft. Large size long-distance aircraft and SST loaded with a great amount of fuel have the jet fuel (JP) increase take-off weight, affecting largely the selection of wing area and engine thrust. If the hydrogen fuel can be liquefied, large reduction can be achieved and the economic effect can be increased. However, for short-distance transport aircraft, the fuel weight ratio is small, where no large advantage is anticipated even if hydrogen is liquefied. Nevertheless, considering oil depletion in the future, a conceptual design was performed on the YX2688 short-medium distance aircraft being discussed of development. Even the short-medium distance aircraft that can be developed and commercialized as civilian use aircraft has a number of common points with large aircraft development, such as hydrogen fuel using technologies and safety. Although the advantage of using liquefied hydrogen as fuel may of course be smaller in the short-medium distance aircraft than in larger aircraft, the trend of using hydrogen fuel is historical necessity, whose development plans should be moved forward.

With an objective to prepare a strategic technological development program for solar heat utilization, evaluations and discussions were given on solar heat utilization from the viewpoints of 'utilizing applications', 'demand' and 'possibility of the proliferation thereof'. In the solar heat utilization, the cost rising in approximate proportion with scale of the heat utilization must be considered as one of the predestined conditions. What can be conceived as a means to enhance the economic performance by using engineering approaches would include heat storage, elementary technologies for transportation and the standardization thereof, and the scale economy on the production side in mass production. As a required step in which the series of favorable circulation of standardization to mass production, cost reduction and large quantity proliferation can be induced, it is appropriate to assume household use with high calorie unit price as the target. The household area covers room heating and hot water supply, in which the temperature level is much lower than in industrial use. In this area, a system may be established with a conception to use solar heat as the main heat source, and calorific power by fossil fuel as the supplementary heat source. Solar heat utilization may be considered utilizable in foodstuff factories and school lunch supply centers. (NEDO)

The capacity and performance of the existing system that recovers the overall heating and cooling exhaust heat completely into a seasonal storage tank and the system that discharges the exhaust heat slightly to the outside and recovers it partially were compared and investigated. The system uses a central single-duct discharge system as an air-conditioning system. A heat pump and a flat-plate solar collector installed on the roof of a building are used as the heat source. The seasonal storage tank in the ground just under the building is a cylindrical water tank of 5 m deep with the concrete used as body. The upper surface of a storage tank is heat-insulated by a stylo-platform of 200 mm, and the lower side surface by a stylo-platform of 100 mm. Calculation when the difference in temperature used in a seasonal storage tank is set to 35{degree}C and 25{degree}C was performed for the system that has two control methods. The overall exhaust heat recovery system is almost the same in energy performance as the partial exhaust heat recovery system. The partial exhaust heat recovery system is more advantageous on the economic side. 4 refs., 6 figs., 3 tabs.

As a part of the WE-NET project, the tanker for liquid hydrogen transport was studied. In fiscal 1996, some experiments and numerical analyses were proposed which are necessary to solve technological issues extracted in fiscal 1995 for heat insulation structure. The issue was roughly classified into vacuum and non-vacuum insulation, and their basic functions and required performance were arranged. Boil-off rate of 0.2-0.4%/d was targeted. The insulation system which applies polyurethane form (PUF) to tank surfaces and injects atmospheric N2 gas into the surrounding hold space, could achieve the targeted insulation performance by PUF of 1m in thickness. The system of vacuum panel insulation and atmospheric N2 gas injection into a hold space required the panel of 500mm in thickness because of the large effect of metallic outer panel material. The system of vacuum hold and PUF panels was faced with the essential issue for realizing and maintaining vacuum hold. The super insulation system featured by layered insulation materials and vacuum layer spaces was also strongly affected by degree of vacuum. 23 figs., 8 tabs.

For the investigation of calibration system of acceleration and force sensor, one-dimensional interferometer system has been developed, which is standardized in ISO5347 accelerometer calibration. Thus, an interference fringe processing software has been made. Moreover, construction of a three-dimensional interferometer system has been started. For the characterization evaluation of pressure sensitive papers, it was succeeded in obtaining an elasticity wave pulse maximum about 1 msec by adopting the flight body made of resin. As a result, evaluation of the force sensor in the frequency area has become possible. To calculate the displacement of a body structural material in the collision experiment, an acceleration sensor has been made for trial purposes. For the international research cooperation, the working plan of a joint research with US Texas Christian University has been concluded. 11 refs., 73 figs., 23 tabs.

With an objective to prepare a strategic technological development program for solar heat utilization, evaluations and discussions were given on solar heat utilization from the viewpoints of 'utilizing applications', 'demand' and 'possibility of the proliferation thereof'. In the solar heat utilization, the cost rising in approximate proportion with scale of the heat utilization must be considered as one of the predestined conditions. What can be conceived as a means to enhance the economic performance by using engineering approaches would include heat storage, elementary technologies for transportation and the standardization thereof, and the scale economy on the production side in mass production. As a required step in which the series of favorable circulation of standardization to mass production, cost reduction and large quantity proliferation can be induced, it is appropriate to assume household use with high calorie unit price as the target. The household area covers room heating and hot water supply, in which the temperature level is much lower than in industrial use. In this area, a system may be established with a conception to use solar heat as the main heat source, and calorific power by fossil fuel as the supplementary heat source. Solar heat utilization may be considered utilizable in foodstuff factories and school lunch supply centers. (NEDO)

A desiccant cooling system uses concentrated aqueous solution of an absorbent to reduce humidity, hence the resultant absorbent solution becomes dilute. Regeneration of the dilute solution uses solar heat, where the regeneration characteristics are affected by solution temperature, vapor pressure, water content, air-liquid flow rate, and other factors. Therefore, mutual relationship among these different factors were investigated, and an optimum operating condition was discussed. The regeneration characteristics of the absorbent is strongly affected by temperature of triethylene glycol (TEG). This is because vapor pressure, Ps, in the TEG aqueous solution increases as the TEG temperature rises. This means that preheating the solution is effective in regenerating the absorbent. As the regeneration progresses, the water content, Ww, decreases, and the regeneration rate decreases. This is because of reduction in the Ps in association with decrease in the Ww of the TEG. This suggests that it is important in the absorbent regeneration to reduce flow rate of the TEG aqueous solution as low as possible. Raised air temperature reduces difference in vapor partial pressure between the TEG and the air, resulting in reduced regeneration rate. 5 refs., 9 figs.

Technologies of producing useful substances using the substance decomposing/producing functions of complex biosystems and methods of their handling are developed. In the utilization of microbes in the digestive tracts of termites and longicorns, it is made clear that several kinds of termites cleave the {beta}-O-4 ether linkage. In relation to technologies for wood decomposing complex microbial system construction and complex vector system development, a screening system is constructed in which strains that exhibit complex actions are combined. Concerning the advanced utilization of tropical oil plants, conditions are determined for inducing callus out of oil palm tissues. Out of oil palm sarcocarp tissues, mRNA (messenger ribonucleic acid) is isolated for the construction of a cDNA (complementary deoxyribonucleic acid) library. For the purpose of isolating a powerful promoter, a partial base sequence is determined for ubiquitin that frequently expresses itself in cells. A pathogenic bacterium ailing the oil palm is sampled for identification, and it is inferred that the bacterium is a kind of Ganoderma boninense. (NEDO)

In order to utilize more effectively coal ash whose generation amount is increasing year after year, studies have been made on a technology to manufacture and utilize a high-strength substance solidified under normal temperature by utilizing hydration reaction of pozzolan system (Poz-O-Tec). The study works have been done as a subsidy operation of the Agency of Natural Resources and Energy, and were completed in fiscal 1995. Poz-O-Tec is a wet powder made of coal ash and stack gas desulfurization sludge (gypsum) added and mixed with lime and an adequate amount of water, which solidifies by hydration as pozzolan does. The same method as used for ordinary sands may be used as the basic application method. Because this is the material whose strength increases after construction, thickness of construction may be reduced smaller than in constructions using soils and sands. Test constructions of about sixty cases have been carried out to date, typically represented in use as a road bed material, banking, and a base material for water-barrier gutters. High-strength solid material which is stable under normal temperature may be obtained by adjusting calcium content. As a result of its effectiveness in practical use having been verified, a certificate of technological judgment has been issued for the material by the Civil Engineering Research Center. 3 refs., 11 figs., 2 tabs.

To suppress the emission of environmental pollutants from coal utilization in China and to contribute to stable security of Japan`s energy, demonstration of clean coal technology and consolidation of diffusion base to be introduced into China have been promoted. Demonstration program for diffusing simplified desulfurizers has been promoted. For accelerating the achievement, experts of desulfurizers were delegated to Weifang Chemical Industry Works, to support the program. Exhaust gas is introduced from boiler via water spray dust remover, suction fan and centralized stack into absorption tower of the simplified wet-type desulfurizer. In the ascending process, the exhaust gas contacts with absorbent, to remove SO2 and dust. The absorbent is blasted up through the spray nozzle. The absorbent is oxidized by the air into sulfate ion in the liquid chamber at the lower part of tower, and neutralized by hydrated lime to form gypsum. Through the continuous operation for two years, understandings were remarkably increased. However, good treatment of the tax system is required for further diffusion. Though there are no problems for ordinary start and stop, emergency operation is insufficient. There are some problems in the maintenance due to the delay of finding failures. 16 figs., 1 tab.

This paper describes development of hydrogen gas turbines from among the comprehensive discussions on hydrogen utilizing subsystems. Hydrogen and oxygen gas turbine cycle has varying optimal conditions of plant efficiency depending on fuel patterns. The regenerative cycle may have the turbine inlet temperature at about 1,000 degrees C. The inlet pressure would be ten and odds atmospheric pressure. It is better to keep the inlet temperature higher in order to obtain high specific power. Reduction of power generation cost in using this plant requires that construction cost be decreased, and the specific power be increased if the plant efficiency (in other words, running cost) is assumed constant. Further development is required on technologies to use higher temperatures and pressures. For that purpose, discussions should be given on material development, structural design, and inspection. Hydrogen gas turbines, which present low pollution depending on combustion methods, have great significance for such social problem as environmental contamination. In terms of economy, since hydrogen gas turbines depend on efficiency and fuel unit cost, the evaluation thereon may vary depending on how well the regenerative gas turbines have been established, in addition to future change in hydrogen price and the technologies to use higher temperatures and pressures.

Described herein are results of survey on brown coal liquefaction techniques and peripheral techniques, centered by COSTEAM process under development in USA, solubilization by alcohol and liquefaction and cracking with the aid of tetrahydroquinoline as the hydrogen donor under development in Japan, and low-temperature carbonization and new promising techniques. The COSTEAM process shows higher reaction rates, conversions and oil yields for brown coal liquefaction than the one using hydrogen gas. Some of the problems involved in this process high viscosity and oxygenated compound content of the product oil. The product oil is acceptable as fuel for power generating plants and can be produced at a moderate cost, but may be unsuitable as vehicle fuel. Coal liquefaction and solubilization processes are mainly represented by those which use hydrogen. The hydrogen cost, which is high, determines the product price. The processes which use alcohol or tetrahydroquinoline are still in the experimental stage. (NEDO)

This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-1. Technologies drawing attentions relate to fuel cell driven automobiles and hybrid automobiles in the field of utilizing hydrogen derived from reproducible energies and fossil energies, and fuel cell co-generation and micro gas turbine co-generation in the field of electric power generation. Hydrogen reformed from gasoline on board the automobile as the fuel for fuel cell driven automobiles, hydrogen as a by-product of coke furnace off-gas (COG), and reproducible energy hydrogen have the same fuel consumption performance as in the hybrid automobiles. Particularly the COG is low in cost, and has large supply potential. Liquefied hydrogen is as promising as compressed hydrogen in view of the cost for automotive hydrogen supply stations. What has high economic performance as the self-sustaining systems for islands are photovoltaic and wind power generation, and the system using hydrogen as the secondary energy. Since much of the reproducible energies is used for electric power demand in Japan, the by-product hydrogen and the reformed hydrogen in an amount of 9.3 billion Nm{sup 3}/year would take care of majority of the demand in view of the short time period. For a longer time span, hydrogen originated from the reproduced energies in the Pan-Pacific Region should be introduced. (NEDO)

For the purpose of contributing to working out a master plan for the introduction of the environmentally friendly type coal utilization system in the Philippines, analysis was made of the state of coal use/the state of spread by industry mostly including the electric power industry, cement industry and residential/commercial use fuel sector. In the Philippines, the amount of coal use has rapidly been increasing since coal-fired power plants started operation. For the promotion of the use of domestic coals, it is important to reform low grade coal. Moreover, the technology is required which copes with the reinforced regulation against SOx emissions. In the cement industry, coal and coal ash have not yet been effectively used. Therefore, the following measures should be taken to increase the competitive force: energy conservation measures, reinforcement of environmental measures such as dust prevention, and effective use of the fly ash emitted from power plants. In general households and small-/medium-sized industries such as tobacco drying, they still use a large amount of charcoals and firewood, which is approximately 86% of the residential/commercial use energy. There is a growing tendency for the development/spread of coal briquette as substituting energy. (NEDO)

The refuse-derived fuel (RDF) has been holding public attention not only as the energy resource of stable high calorific value for local energy development, but also as the effective method for waste treatment. As one of the effective utilization methods for waste treatment, this investigation was conducted to industrialize and establish the RDF power generation system, in which power generation and ash treatment are integrated in Tochigi Prefecture which is located inland. The base supply type was adopted as a way of operation from the menu of the electricity wholesale project of Tokyo Electric Power Co. and its rate of operation is 80 percent a year. Then, the fluidized bed combustion method, a dry exhaust gas treatment method, and continuous electric melting furnaces were decided as the RDF power generation system. According to this system, it is possible to obtain 26 percent gross thermal efficiency by conventional generation facilities. It was estimated that the expenses reduction for 15 years will be 17.6 billion yen compared with the ordinary combustion system. Also, the following effects can be expected; the reduction of CO2 emission, improvement of energy efficiency, and the extension of life of landfills capacity. 36 figs., 51 tabs.

This paper describes the measurement and analysis for clarifying solution structure of supercritical water and exhibition mechanism of solvent functions. It also describes the development of new processes using supercritical water as reaction solvent. The PVT measurements were conducted in the supercritical region using pure water and NaCl aqueous solution, to confirm the reduction of molar volume of the electrolyte solution. The hydration structure was examined in the supercritical aqueous solution by the molecular dynamic simulation. As a result, presence of hydrogen bond structure, where the contribution of two branching hydrogen bond can not be ignored, was suggested under the supercritical condition. Characteristics of supercritical aqueous solutions are analyzed through in-situ Raman and scattered X-ray spectral measurements. Moreover, this paper introduces developments of some processes in the supercritical water, such as decomposition of wasted polymers, recovery of chemical materials, reforming of heavy hydrocarbons by contact hydrogenation, and synthesis of fine powders of metal oxide by reaction crystallization.

The paper described the fiscal 1996 developmental results of hydrogen burning turbine combustion technology in the hydrogen utilization international clean energy system (WE-NET) project. A test was conducted on an annular type combustor where oxygen is mixed with steam (inert gas) at burner and fired with hydrogen. Appropriate flame shape and cooling/dilution vapor distribution were attempted, and various data on combustion were measured for improvement. Mixture and flame holding were improved by developing a can type combustor (1) where oxygen is diluted with steam after firing oxygen and hydrogen around burner and by strengthening circulation in the combustor. Improvement such as appropriate steam distribution, etc. is needed. A can type combustor (2) was tested in which the premixed oxygen and hydrogen is supplied from scoop and fired with hydrogen. By supplying part of oxygen from the primary scoop, the residual hydrogen and oxygen concentration around the stoichiometric ratio can be reduced. Concentration of the residual oxygen can be measured by the absorption light method, but it is difficult to adopt the non-contact measuring method to hydrogen. An outlook for the gas temperature measuring method was obtained. 12 refs., 121 figs., 27 tabs.

This report summarizes the fiscal 1999 research result on the safety of hydrogen absorbing alloy tanks for hydrogen vehicle systems and the measuring method of a fuel consumption rate of hydrogen fuel cell powered vehicles. In the impact rupture test of (mini-scale) hydrogen absorbing alloy tanks, the impact 3-point bending test result by drop weight showed no ignition caused by impact and friction energy acting on hydrogen released by rupture of tanks, and the necessity for taking spontaneous ignition of alloys due to fuel leakage into account. The experiment result on deformation and rupture of alloy tanks caused by expansion and contraction of crystal lattices due to hydrogen absorption and desorption showed relatively large deformation due to grain fining only within earlier 10 cycles, and no cracks nor other defects even after 1000 cycles. In the measurement of a fuel consumption rate of hydrogen fuel cell powered vehicles, the study result on flow rate measurement method, full tank method, electric current method, hydrogen balance method and oxygen balance method showed that the electric current method is most simple, accurate and practical.

To introduce the power generation system fueled by animal waste (excrements), one of the so-called industrial waste, its feasibility has been studied in Koyu and surrounding area located in Miyazaki Prefecture. This report includes the technical feasibility of available quantity of animal waste, chemical analysis of the waste, and basic design of the power generation system containing the furnace model and also its economical feasibility. The available quantity of animal waste in Koyu area is about 169,000 tons a year, which can generate 10.5 MW of electric power. That including the surrounding area is about 219,000 tons a year, which can generate 15.0 MW. The heating values of animal excrements in average and as received are 970 kcal/kg for pigs and 1,230 to 2,700 kcal/kg for broilers. In the case of combustion of mixed broiler and pig excrements, both of the stoker and fluidized-bed model furnaces become refractory furnace construction and provide with heat recovery boiler due to their high moisture content. In addition, the stoker furnace model requires an excrement dryer system as pre-treatment of fuel. For the fluidized-bed furnace of 15 MW grade power plant using the mixed fuel of 50% broiler excrements and 50% pig excrements, the power generation efficiency of 23% can be expected at generator end. The generating cost is around 10 yen/kWh. 27 refs., 61 tabs.

The paper described the result of the fiscal 1996 development relating to hydrogen combustion turbines, as one of the hydrogen utilization technologies, which have excellent environmentality and are expected of remarkably high efficiency. In the film cooling system of first-stage moving/stationary blades, the smaller the pitch of film pore is, the higher the mean cooling efficiency becomes, indicating 0.7 at maximum. As compared with the conventional shower head type, the metal temperature can be reduced 30-40degC. In the recovery type inner (convection) cooling system, by reducing the blade number, the consumption amount of coolant can be reduced 6% in stationary blade and 13% in moving blade, as compared with the result of the preceding year. In the element test of the hybrid cooling system, film cooling efficiency was actually measured by the porous module test equipment, and the result well agreed with the calculation result. In the water cooling system, studied were water (stationary blade) and vapor (moving blade) of the closed cooling structure for realization of a cycle efficiency of 60%. In rotor/disk cooling, analyses were made of seal characteristic grasp tests and characteristics of the rotor. The effect of deflection in the mainstream was small.

This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for Task-4, the development of a motive power generation technology. The objective is to build a 100-kW class single cylinder hydrogen-argon circulating diesel system. For a hydrogen injection valve being the key to the system, development was made on the conventional hydraulic system with quick compression, expansion, and electronics control. Discussions were given on an exhaust gas condenser and a gas-liquid separator to handle gas mixture with low steam concentration. In order to assure the mechanical strength to deal with the argon working gas, super-chargers and expansion turbines were also discussed. When the hydrogen injection pressure is increased from 20 to 25 MPa in the basic test, the combustion speed has increased, and the indicated thermal efficiency has been improved. The same effect was obtained also when the oxygen/argon ratio was increased. Although the thermal loss increases if the oxygen/argon ratio is increased, the loss in the indicated thermal efficiency is compensated by the gain derived from increasing the combustion speed. When argon is used as the working gas, the temperatures in parts of the combustion chamber rise much higher than that in the case of a light oil diesel system. Therefore, discussions were given on materials and structures that can withstand elevated temperatures, and assessments and tests were performed on high-temperature lubricants. (NEDO)

Development is intended on an efficient management and control method for EV car rentals in tourist resort areas using the ITS technology from the viewpoints of reducing road traffic load and global environment problems. The development items include a control center system, a system to control battery charging status at the center, a battery charging determination algorithm, and a car navigation and bi-directional communications mounting system. The system development has been completed nearly completely, having attained relatively high user satisfaction. However, because of the experimental rented cars having long mileage, there were few chances of verifying the charge determination algorithm and the functions of the ITS. Investigations were carried out on technological trends in overseas countries on EV and ITS, and on commuter car introduction projects. Structuring the hardware for a commuter EV system is not too difficult if the presently available EV and ITS technologies are used. However, in advancing commercialization, there are such assignments as establishment of software, operation patterns, and interfaces that enhance user convenience and profitability. (NEDO)

Mutnovsky is a geothermal field which lies to the south of and about 80km away from Petropavlovsk, Kamchatsky, the state capital of Kamchatka. The geothermal survey has been conducted since 1978 in this field. In this study, the self-potential variation was observed by monitoring the potential difference between places near and far from a well in the same region. Then, the self-potential associated with spurting vapor from a well was analyzed using a model of the self-potential generated from the steaming current coupled with the flow of hot water in the porous medium. As results of an experiment on the spurt of stream, vapor containing 80% stream in weight was exhausted at a mass flow rate of 30kg/sec at 100degC from wells. Since the specific enthalpy of this vapor is 2225kJ/kg, the underground geothermal storage layer was estimated to be a state of liquid and vapor two-phase. 9 refs., 6 figs.

An intercellular transport technology (artificial manipulation of an intracellular protein transport system in eucaryotes) is studied for the accumulation of cytotoxic proteins, whose expression has so far been difficult, and activated proteins, which have avoided decomposition, in appropriate intracellular minute organs. The aim is to construct a system to allow foreign proteins high in productivity and quality to express themselves for production in eucaryotes. Basic surveys were conducted of the intracellular biological functions of single-membrane organelles (endoplasmic reticulum, peroxisome, vacuole/lysosome, and Golgi body), the molecular mechanism of protein transport to each organelle, and protein activation and quality control, and element technologies were extracted. For the development of novel pharmaceuticals making use of the intracellular protein transport technology, an activated protein production system was built and a search was made for transport activity impeding substances. Research tasks relative to the development of the new technologies were isolated, such as the visualization of intercellular transport. A survey was made of the market for pharmaceuticals, cosmetics, enzymes, and visualizing equipment (fluorescence microscope provided with new functions), etc. (NEDO)

This paper describes a possibility of geothermal utilization in Tomakomai City. The Tomakomai area has an extremely great amount of hot water existing in deep layers, leading to a consideration that it is very highly possible to develop the hot water. As seen from the underground structure and ground temperature gradient in the Tomakomai sedimentary basin, the development depth would be considerably great, being assumed to be about 2,000 meters. The acquisition amount per well is estimated 100 m{sup 3}/hour or more at 65 degrees C. Rise in petroleum price in the future is an unavoidable fate, hence geothermal water utilization has a fully bright future. The water has relatively low temperature, and is effective for use in room heating, hot water supply, and agricultural and livestock industries. It is worth considering utilization as a local energy system. It has also large secondary effects. According to the latest trial calculation, the unit price for hot water for room heating and hot water supply would be 10 to 20 yen per 1,000 kilo-calories. If the same amount of hot water should be supplied from a boiler, fossil fuel of 20,470 kl/year would be required. If converted by using a kerosene price of 75 yen per liter, the cost would be 1.3 billion 35 million yen, comparatively higher than the geothermal water utilization. (NEDO)

R and D has been performed on a system to detect well bottom information during geothermal well drilling (MWD) to identify items of well bottom information during drilling on a real time basis. This paper summarizes the achievements in fiscal 2000. This device measures and transmits to the ground surface the following items during geothermal well drilling at good accuracy under the mud water temperature of 200 degrees C: azimuth, inclination, tool face, bit load, bit torque, temperatures in the device, downhole temperature, and downhole pressure. The current fiscal year has performed improvement of the sonde, including decrease of the sonde length, electric power conservation, enhancement of anti-noise performance, and enhancement of operability. For the sonde performance evaluation, high-temperature test, long distance loop test, and vibration test were carried out. In addition, the experiment analyzing program (for noise processing) was improved. With regard to the well trajectory control aiding system and the well evaluation aiding system, an operation manual was prepared, entitled the 'MWD analyzing system'. Unification was attempted on the hardware of the ground surface detection device system and the analyzing system. (NEDO)

This is aimed at making an investigational study on the hydrogen production from water by means of quinone compounds. The paper studied a preparation method in case of using n-TiO2 photosemiconductor and p-GaAs and Gap photosemiconductor to photoelectrode as catalysts of this reaction. The reaction from p-benzoquinone to p-hydroquinone by reaction with H2O were studied in terms of photochemical reaction, and light reaction/dark reaction of photosemiconductor electrode. As a result, it was found out that this reaction easily advances by the photochemical reaction by solar light, and also that it advances by the counter electrode Pt electrode reaction in the water electrolysis of n-TiO2 photosemiconductor electrode. The H2 production reaction from p-hydrogquinone was studied in terms of the photochemical reaction, photosemiconductor electrode reaction, and effects of the catalysis of electron transport of metal salts, methylviologen, etc. As a result, in the n-TiO2 photosemiconductor electrode reaction, H2 formation was not as great as it can be confirmed. However, it was found that p-hydroquinone can produce H2 under the existence of methylviologen or Fe salts. (NEDO)

The paper outlined the present situation of industrial waste all over Japan and the present situation of industrial waste of large urban areas where it is most difficult to secure places for the final disposal, and conducted an analysis on the present and future amount of final disposal waste. According to the literature from the Ministry of Health and Welfare, `research report on the discharge/treatment situation of the industrial waste` and `research results of administrative organizations for industrial waste,` the situation of final disposal from the past to the present was outlined and analyzed to study the future trend. Out of the administrative divisions of Japan, four divisions, which are all typically called large urban areas, were selected, and the situation of industrial waste in large urban areas was outlined and analyzed according to the questionnaire survey and the literature on industrial waste obtained from each administrative division. The survey by the Ministry of Health and Welfare indicated that the volume of the industrial waste discharged from the whole country amounted to approximately 400 million tons in fiscal 1992. However, helped by the improving recycling of waste construction materials, the amount of final disposal around 2000 is presumed to be less by 20% or so than that in 1992. 58 refs., 5 tabs.

This report describes the results of effective fixing technique of CO2 by utilizing solar energy. First of all, the investigation was directed to the technique for synthesizing ethylene, hydrocarbons and alcohol by electrochemical reduction of CO2. The power required for this process is supplied by photovoltaic power generation. Development of excellent electrode catalyst is needed because the reduction of CO2 requires a high overvoltage. It is desirable to enhance the selectivity of the reaction for specific material and improve the transport process in the electrolytic cell. Next, designing of material and reaction of photocatalysts using semiconductor electrode and semiconductor particulate was examined. A semiconductor electrode made of FeS2 is inexpensive and has a high ability of collecting solar light. In the category of photocatalysis system, a photocatalytic system in which semiconductor particles are embedded in vesicle and a photpocatalyst based on potassium niobate are noteworthy. As biosystem, the method of reducing CO2 by calcareous algae which simultaneously advances fixing and calcification of CO2 by photosynthesis is noteworthy. 129 refs., 45 figs., 20 tabs.

The effort of fiscal 1997 at isolating the best way to introduce a relatively small amount of hydrogen into urban fuel economy was carried over to fiscal 1998. In the research of fiscal 1998, comparison was made between Tokyo and London in connection with hydrogen introduction, and a transition scenario was proposed for introducing hydrogen into Tokyo. Models were built for Tokyo and London, and studied. The result of this study was different from that obtained in the previous study, and places the two cities under similar conditions. The difference is attributed to the rapid progress in the development of the fuel cell and to the resultant reduction in cost. It is inferred that, in consideration of the transportation situation, the introduction of pure hydrogen will be the most cost-effective for both cities at least for some time to come. According to the revised data, natural gas may be procured in Tokyo as in London but the size of supply available in Tokyo is fairly smaller than that in London. Several transition scenarios covering the period up to 2025 were subjected to discussion. (NEDO)

Survey and experimental research have been carried out on coal gasification using a pressurized internal circulation fluidized bed, spouted bed hydrogenation pyrolysis, supercritical water gasification, and a possibility of efficiency improvement by utilization of catalyst in chemical raw material production spouted bed gasification system. In the coal gasification using the pressurized internal circulation fluidized bed, an experiment was performed by using active alumina and Ni catalyst, where outstanding effect was identified. In the spouted bed hydrogenation pyrolysis, an experiment was executed by using iron hydroxide catalyst, but no noticeable effect was recognized. In the supercritical water gasification, an experiment was carried out by using Na{sub 2}CO2 and K{sub 2}CO{sub 3} catalysts, where it was found that the effect of the catalysts is little in the supercritical gasification reaction area of 800 degrees C. The power generation system composite with the chemical raw material production spouted bed gasification is a one-path system in which coal is gasified by the spouted bed gasification furnace, catalyst and steam are put into a heat exchanger to perform DME synthesis, and non-reacted gas is supplied as gas turbine fuel. Estimation was made on the possibility by an on-the-desk study, which requires experiments in the future. (NEDO)

Introduction of geothermal heat pump systems, which depend on temperature differential, is investigated for urban areas, which have large energy demands. Results of the surveys on the current situations of geothermal heat pump (GHP) systems indicate that they have already numbered 300,000 units in USA and totaled more than 50,000 units in Switzerland and Northern European countries, and that they are increasing at an annual rate of higher than 10%. The results also indicate that introduction of these systems are well feasible in Japan, which generally has better topographical conditions than American and European countries, and the GHP system with vertical ground heat exchanger is investigated for its topographical and environmental considerations. These systems could annually abate approximately 52 million tons of CO2 (4.3% decrease), if disseminated to all households. They are also expected to help control the heat island phenomenon, and reduce peak power consumption. The technological problems to be solved before these systems are massively disseminated including development of small scale drilling rigs and preparation of drilling manuals. System standardization and introduction of subsidy systems are also needed to massively disseminate these systems. (NEDO)

Various surveys were conducted for the area around the Nojima fault, including ground surface, two-dimensional electrical and boring surveys and elastic wave tomography, in order to grasp properties of the ground around the `Nojima earthquake fault.` The resistivity image method as one of the two-dimensional electrical methods was used to grasp fault shapes over a wide range of the 1.6km long section extending between Esaki and Hirabayashi. The courses of traverse were set in the direction almost perpendicular to the fault. Boreholes were excavated and elastic wave tomography was conducted between the boreholes on the 9th and 17th courses of traverse, to confirm ground/mountain conditions and to compare the results with observed elastic wave velocities. Very low resistivities are observed at places where granite is distributed, suggesting that the fault-induced changes are not limited to the area around the fault. The zone in which elastic wave velocity decreases is narrow, 10m at the longest, at a velocity of 2.4km/s or lower, which is a low velocity for that propagating in granite. 5 refs., 4 figs.

Supply capacity of practical size of 1/10, 30 Nm{sup 3} was selected as the object. For the natural gas reformed type hydrogen generator, discussions were given on design and manufacture of a reforming unit and a PSA device. The PCT diagram method was discussed to estimate the capacity of a hydrogen absorbing alloy type storing facility. Interface between fuel cell driven automobiles and the station was adjusted. For the solid polymer electrolyte water decomposition type, safety measures were discussed with a high-pressure filling system kept in mind. Detailed design was made on a water decomposing hydrogen generator. Fabrication was completed on the hydrogen absorbing alloy type storing facility, and verifications were given on the storage amount, hydrogen absorbing speed, and discharge capability. In the high-pressure refueling system, temperature rise was simulated at a pressure of 35 MPa. Refueling for ten minutes raised the gas temperature by 75 degrees C, and the container surface by 65 degrees C. Local temperature rise was forecasted in the actual work, which is a future discussion assignment. An outline method was discussed for the verification test. (NEDO)

The purpose of the project in FY 1998 is 'Experimental verification for EV spread promotion.' Two of a 3-month experiment were conducted in Yokohama MM21 area (Yokohama, Kanagawa) and in Tama Newtown (Inage, Tokyo) using a total of 100 (50 each) small EVs. The development was aimed at of an urban type rental-car system in Yokohama and of a car-sharing type second-car system for residential in Inage. As to these responses to ITS technology, the basic vehicle operation system was made common in both areas, and the daily use system was made a regional system considered of purposes of use, regional characteristics, etc. The experimental verification was worked on as almost expected in terms of the vehicle management, monitor assessment, responses from persons concerned in both areas. Therefore, it is said that the R and D have almost reached a point where there can be seen a possibility of system commercialization. Through the experimental verification, the development was able to be smoothly promoted of the basic technology and element technology which are thought to be needed for the commercialization of EV. From the experience of this experimental verification, it is judged that it is desirable to tackle the commercialization by a membership system when the commercialization of EV joint use system is planned in future.

Survey was made of the case of applying the low grade coal reformation technology to commercial plants in Indonesia. In the survey, supposing the UBC process as reformation technology and 5,000 t/d as size of the commercial plant, studies were made of companies to be applied, schemes on the usable fund raising/governmental supporting policy, potential diffusion/effects of diffusion, facilities which can be domestically manufactured/subjects in promoting the domestic manufacture, economic F/S, etc. Different from the first generation coal companies, the second generation coal companies own low grade coal for the most part of the coal resource. Therefore, the companies are very much interested in the reformation technology. In the financial plan, the equipment cost of a commercial plant of this size was estimated at approximately 10 billion yen. This is a large initial investment for coal companies in Indonesia. So, it is necessary to consider a system of joint venture with Japanese users, etc. As to the study of the economical efficiency, the trial calculation indicated that the reformation cost was 7.35 US$/product ton and the price of reformed coal briquette product was 19.85 US$/product ton. In this case, ROI (return on investment) of 8.40%/year was expected. (NEDO)

The target storage capacity of 50,000m{sup 3} was reasonable, however, the performance of loading arms should be examined. The capacity around 5,000m{sup 3} of coastal localized bases was reasonable for control delivery loss caused by coastal tanker or LH container system to 2.6%. The capacity of 500m{sup 3} was suitable for inland bases, resulting in the loss of 1.2%. The concept design of the storage tank of 50,000m{sup 3} extracted confirmation of low-temperature characteristics of adiabatic materials and structures, and development of leakage inspection technology and vacuum holding technology as issues. The concept design of the underground storage tank showed that the material specifications for LNG ones are applicable to it by using proper adiabatic structures. 4 refs., 72 figs., 27 tabs.

The geographical position or environment is set on the assumption that the natural energy of a detached house is used in a hybrid state. Moreover, the energy consumption of the house and the natural energy supply obtained from the geographical position were compared and investigated. As a result, the energy consumption is 10,617 kWh, and the energy supply is 8,236 kWh. About 78% of the whole consumption can be theoretically made from natural energy. The energy supply is calculated on the low side during prediction. Therefore, an increase in the energy supply is expected by installing a solar collector based on solar energy, expanding the solar panel area, and increasing the number of wind mills. However, this energy is partially lost via an inverter while it is supplied to the general domestic equipment. At the six main points in Tokyo and its districts, the adaptability of natural energy used based on the regional characteristics is investigated presently and the installation of a system is examined. 13 refs., 2 figs., 6 tabs.

This paper describes the achievements in fiscal 2000 from the WE-NET Phase II for research and development Task-6. The objective is to verify performance and reliability, by means of field tests, of a power generation plant using fuel cells of pure hydrogen fueled solid polymer type with power transmission terminal efficiency of 45% and output of 30 kW. The fuel cells were developed by using the cathode humidification process as a humidification method suitable for operation at high utilization rates. With a three-cell stack made by using this humidification process (having an effective area of 289 cm{sup 2}), verification was made on the current density of 0.2A/cm{sup 2}, the characteristics of 0.75V or higher, and the uniform voltage distribution performance being the immediate targets. In order to mitigate the hydrogen utilization in the fuel cells, discussions were given on the serial flow system that divides the laminated cells into two blocks. Thus, operation was found possible with the utilization rate in each block reduced to about 80% by selecting an adequate division rate even if the hydrogen utilization rate is 96% in the entire stack. Stable operation has been performed in the 5-kW class power generation test using the cathode interior humidifying system. Specifications for 30-kW class power plant, system configuration, safety, and material balance were discussed. The basic design was made on the hydrogen gas humidity adjusting system. (NEDO)

Discussions were given on mass cultivation in a water tank using sea water of an alga Ulvales used as feed for sea urchins and abalone. A fertilizer composed of ammonium sulfate and superphosphate of lime was used, and a water temperature was set as the environmental condition. Two kinds of Ulvales produced in different areas were used. One of the two kinds had full growth periodical and weight increasing rate low, but the other Ulvales had high weight increasing rate and no blights in alga bodies, and was found suitable for mass production. The result of a test on stocks of the latter species may be described as follows: multiple regression formulas for harvest, water temperature and illumination intensity were introduced for each cultivating condition for four cases regarding accommodation density and harvest frequency; and if a cultivating condition by which the harvest is maximized is adopted, a one cubic meter water tank placed on a place with good sunlight may be expected of producing as much harvest as 2181 grams at water temperature of 15{degree}C and 4899 grams at 25{degree}C. The cultivation requires the following precautions: aeration is required; sea water should be introduced into the tank; a mixed fertilizer with ratio of ammonium sulfate at 100 to superphosphate of lime at 15 may be used; water temperatures suitable for mass cultivation are 13 to 15{degree}C or higher; and light must be irradiated evenly. 14 refs., 9 figs., 5 tabs.

To verify the clean coal technology to be diffused in China and consolidate its diffusion basis, demonstration project of circulating fluidized bed boiler was conducted through the cooperation with China which is positive in its introduction. This report describes its characteristics. Coal and limestone are supplied in a lower part of combustion chamber, and are mixed with circulating ash by fluidized air for combustion. Densely fluidized bed the same as the bubbling fluidized bed is formed in the lower part of combustion chamber, which provides excellent stability in ignition and combustion. Particles including ash, char and limestone formed during the combustion are discharged into the cyclone through the convection heat transfer part at the outlet of combustion chamber with the combustion gas flow. Since the gas temperature is lowered to 400 to 500degC at the convection heat transfer part, troubles of the ash circulating system can be prevented. The combustion gas separated from ash at the cyclone is discharged through the heat exchanger and precipitator, and the collected ash is returned to the lower part of combustion chamber. In FY 1997, design, fabrication, procurement/inspection, field survey/meeting, survey of visitors/meeting, and education were carried out. 4 figs., 4 tabs.

Research and development has been performed on a technology to manufacture hydrogen effectively from water utilizing solar beam and using an organics oxidizing and reducing system as the intermediary, and its achievements in fiscal 1984 was reported. With regard to the process in hydrogen generation stage as the first step, water dissolvable rhodium complex was synthesized to improve the process having been developed in the previous fiscal year. Its photo-hydrogen generation capability was discussed. In the rhodium complex of ligand having sulfonic acid group for water solution, a system using only water as a solvent was discovered to show the photo-hydrogen generation capability equivalent to or greater than the system of organic solvent and water using non-water dissolvable rhodium complex. In the stage of reduction of oxidized type organics by water as the second step, discussions were given on photo-electrochemical behavior of iron oxide sintered electrodes. Photo-hydrogen generation was investigated by retaining the electrode potential to a potential generated by beam irradiation onto the iron oxide sintered electrodes, and using a system of water dissolvable rhodium complex and rhuthenium complex. As a result, a possibility of recycling the materials was discovered. (NEDO)

The paper studied a system to effectively use unused and low-grade thermal energy (cold heat and hot heat) in the Tokyo-Yokohama seaside area. For transportation of thermal energy, the batch transportation, that is, off-line system was discussed which uses insulated tank loaded barges and railroad freight trains. Thermal energy supply sources are 1) 0.3 million kW class thermal power plant, and 2) LNG storage base of 3 million ton/year class. Thermal energy users are Tokyo (Haneda) Airport D.H.C. (District Heating/Cooling Co.), MM 21 D.H.C. and Shin-Kawasaki D.H.C. The cold heat energy supplied to these three is about 1.5 million Mcal/daytimes300 days/year, and the hot heat energy supplied is about 1.33 million Mcal/daytimes150 days/year. Cold heat is obtained from seawater after the LNG vaporization, and hot heat from heat extracted from thermal turbine. Subcooled ice was selected for cold heat medium, and PCM-120A for hot heat medium. For batch transportation, an STL heat storage system is used which transports plastic capsules sealed with heat medium. Oil saving of 62,000 tons/year and CO2 reduction of about 53,000 tons/year can be expected. 85 figs., 98 tabs.

With relation to the energy supply/demand in Japan toward the second half of the 21st century, an analysis was made using the MARKAL model to predict the amount of hydrogen introduction in the future. As in the last fiscal year, conditions of the study of IEA/ETSAP were continuously used. It was decided on that hydrogen was produced by hydroelectric/photovoltaic power generation overseas. Prices were made 14 yen and 27 yen/103 kcal. The limit price of introduction of import hydrogen was calculated. During the period from 2030 to 2050, if the hydrogen price is less than 7 ten/103 kcal, the result showed that hydrogen can be introduced in a lot of scenarios (case of the severe control of CO2 emissions, case of high priced fossil fuels, case of the low capacity of the development of nuclear power generation, etc.) As the form of hydrogen use, promising are the hydrogen combustion turbine power generation, mixture with town gas (hythane) and hydrogen cars. However, a precondition for the introduction is that the cost of hydrogen car should be more economical than the competitive means of transportation. As to hydrogen combustion turbines and hythane, the quantity of hydrogen introduction depends little on variations of characteristics of the equipment used. 11 refs., 55 figs., 21 tabs.

Efforts are made to grasp the parts remaining technically unsolved of the ozone-aided technology for creating a comfortable environment, such as ozone-aided enhancement of the decomposition of nondegradable organic matters in the urban sewage and industrial wastewater. Efforts are also made to put in order and analyze data about the said technology, to isolate the current problems and the objects of technical deliberation for the future, and to examine the feasibility of the introduction of this technology. Case studies were conducted for a novel ozone-aided system and the effect is examined of the introduction of ozone-aided treatment into crowded towns, water supply systems, sewerage, and industries that handle paper and pulp, chemicals, electric power, and foods. Findings are mentioned below. The ozone utilizing technology when introduced improves the efficiency of water circulation, reduces pollutants at an excellent rate, suppresses the generation of carbon dioxide, and enhances safety of water resources and water environments. To realize such good results, however, it is important for the ozone to be high in concentration, for the accelerated oxidation and enhanced biofunction processes to be further studied, and for the system to be optimized. It is also found that a technology of appropriate ozone storage will help enhance cost reduction. (NEDO)

For the establishment of the basis of supercritical fluid technology, we perform elucidation of the specific feature of the supercritical fluid as a reaction media and development of some new process. In this study, we first studied the fluid structure of SCF through in-situ spectroscopy and MD simulation. As a result, significant hydrogen bonding amongst water molecules and a solvation structure around the solute were observed in the supercritical state. This fluid structure has new features different from that of high temperature steam or liquid water. We found that this is closely related to the difference of bulk properties of SCF and local one around the solute. On the basis of these fundamental findings and with the better understanding of the specific features of SCF as a reaction media, development of some new process had been conducted more efficiently and successfully. The processes being developed in this study include 1) waste biomass and plastic conversion to recover chemicals, 2) hydrogenation of heavy oil for desulphurization through partial oxidation 1 and 3) hydrothermal synthesis of metal oxide fine particles.

Cellulose produced by bacterial is called bacterial cellulose (BC). The morphology and physical properties of BC are found to be quite unique in comparison with those of higher class plants. The properties are elucidated and a study is made to utilize the properties. The outline of this study is introduced in the sequence of BC production, BC morphology, elucidation of the physical property, and study on the application. BC consists of ultrafine fibers, and the widths of fibers are in the range from (1/199) to (1/1,000) of cotton fibers, forming distinctive network structure. It is assumed that the high Young`s modulus is based on the structural features of BC. Researches have been made on various applications to such fields as audio, paper, food, and compounds where the features of cellulose are utilized effectively. The morphology of cellulose can be varied by adding drugs which can change a part of the protein. It is expected that cellulose structure can be controlled in the future by the application of this technology. 18 refs., 6 figs., 2 tabs.

At the present stage, however, it is still early to enter into the stage of discussing the standardization. Therefore, in this fiscal year, only in the field of the storage/transportation/handling of liquid hydrogen, standards/laws abroad and in Japan were comparatively investigated for the basic study toward the standardization. Further, concerning ISO/TC197, studies were proceeded with of the liquid hydrogen land vehicle fueling system interface/fuel tanks/transportation containers/hydrogen fuel product specifications/airport hydrogen fueling facilities. Some are at the stage of drafting the international standard. Three drafts for the new standard were added such as gaseous hydrogen/hydrogen blend vehicular fuel systems, gaseous hydrogen fuel tanks, and basic requirements for safety of hydrogen systems. The standardization is indispensable to introducing the developed technology to the commercialization. 9 refs., 5 figs., 13 tabs.

Twenty six years have passed since the first geothermal power station was constructed in Matsuo-mura of Iwate Prefecture, Japan. This paper describes the history, the present situation and the future conception of the geothermal energy utilization in this village. This village includes Hachimantai of a vantage ground in the center and has the gross area of 233.8km[sup 2], the annual average temperature of 8.3 centigrade and the continuous snow cover period of about 100 days. The hot water leading facility was cooperatively constructed by Japan Metals and Chemicals, Hachimantai Hot Spring Development and Matsuo-mura. The total working expense is 539.3 million yen. Hot water sources are the condensate from the condenser of geothermal power plant and hot spring. This mixed hot water of 4.3 t/min is led to respective facilities. The hot water supplying channel has the length of 12.8km from the power station through the Hachimantai hot spring resort, Kamiyogi to Takaishino. Respective total areas of greenhouses using hydrothermal fluid in both districts are 1,075ha and the inlet temperature of hot water is 60 centigrade and kinds of crop are 5 like green pepper and others. Takaishino agricultural park has selected flower and ornamental plant culture such as poppy anemone, stock and statice which are suitable for this district of low temperature and insufficient sunshine.

This paper describes the verification test on power generation by using natural gas driven micro gas turbines (rated at 28 kW) in Thailand. The turbine presented excellent result of providing a maximum power generation output of 25 kW, having no efficiency deterioration even at the 50% output point (about 22%). Its exhaust gas emitted under the normal operation is clean. The waste heat is as low as 290 degrees C, which can be used for hot water supply, but may be difficult for steam generation. Under the severe condition for building large power plants in remote areas due to environmental issues and power transmission loss, proliferation of the discrete power generation system in the suburbs of the city of Bangkok draws expectation. This system can be more advantageous than the existing facilities if the end user gas price is 6.7 Bht/m{sup 3} or less. Discussions were given on a hybrid electric vehicle (HEV) bus driven by electric power generated from the gas turbine mounted on the bus. The bus is overwhelmingly superior in the environmental aspect to diesel fueled buses. The HEV bus emits no black smoke at all, and NOx emission is as low as about 1/70. Fuel consumption is less than half (when regenerative braking is used). However, the vehicle body cost is higher by 40%. Smooth operation of the buses requires indispensably deployment of compressed natural gas service stations (to be located at 40-km interval ideally). Assistance is required also on the fund for gas line installations, and civil engineering construction technologies. (NEDO)

Survey was conducted on the actual state and the potentiality of reusable energy (RE) in the South Pacific nations. The countries to be surveyed were Australia, New Zealand, Papua New Guinea, the Fiji, the Republic of the Marshall Islands, and the Republic of Nauru. The subject RE are photovoltaic power (PV), solar heat, wind force, biomass, hydraulic power and geotherm. The survey items were as follows; RE policy and promotion programs, technical level of makers, RE supply areas and population for independent/linking type electric power systems, population of non-electrification areas, meteorological data, foreign investment policy, feasibility for introduction if RE not yet introduced, and potential of promotion if RE already introduced. Propositions are as follows. Australia and New Zealand, having a comparatively large population and a stable government, are the two most important markets for RE technologies. The South Pacific nations have a markedly small population, providing a limited market for RE systems. Papua New Guinea, being a country possessing natural gas resources, has a chance of developing photovoltaic and fossil energy hybrid systems. The Fiji shows possibility for hydraulic, wind force and biomass power generation. (NEDO)

Efforts are put into the study of direct iron making for use in a closed system where heat energy from a multi-purpose high-temperature gas furnace expected to be developed in the near future will be utilized for iron making. The researches, carried out for the establishment of technologies necessary for designing, building, and operating a pilot plant dimensionally suitable for connection to a 50MWt multi-purpose high-temperature gas furnace, cover the plant total system, a high-temperature heat exchanger, ultrahigh-temperature alloys, high-temperature insulating materials, a reduced gas generating unit, and a reduced iron making unit. When the effort is evaluated as a whole, it is found that the newly developed system is effective in preventing pollution, emitting but 0.1Nm{sup 3} of SOx per 1 ton of crude iron against the 0.4-0.9Nm{sup 3} emitted by a blast furnace/converter iron making mill. It is also found effective in reducing fossil fuel dependence and in enhancing energy source diversification. When it comes to energy conversion efficiency, furthermore, it is shown that the new system achieves a rate of 60% or more while only approximately 30% is attained by light water reactor power generation and approximately 40% by a high-temperature gas furnace.

For conversion of solar heat to transportable energy, hydrogen production by direct thermal decomposition of water using concentrated high-temperature solar heat was studied. Water vapor is injected into the tubular target with high melting point and high oxygen permeability at high temperature while heating the target by concentrated solar heat over 2000K. Oxygen in decomposed gas is discharged through an oxygen permeable membrane to extract hydrogen. Solid electrolyte is used as one of the target materials. Oxygen gas in the high-oxygen partial pressure site changes into oxygen ion by accepting two electrons at the target surface, and returns to neutral oxygen gas in the low-oxygen partial pressure site by discharging two electrons at the surface after permeation through oxygen vacancy. In the case of n-type solid electrolyte, to obtain constant permeation of a large amount of oxygen, flow of a large amount of electrons is indispensable in the opposite direction to oxygen ion. Among [(ZrO2)(1-x)(CeO2)x](0.9)(CaO)(0.1), materials of 0.4-0.5 in x seems to be useful as the target material. 7 refs., 7 figs.

This paper describes the achievements in fiscal 2000 from the development of candidate low-temperature materials for liquid hydrogen transportation and storage (including mother materials and welds) for WE-NET. Evaluation tests were performed on material properties (mechanical properties, low-temperature embrittlement, and hydrogen embrittlement sensitivity) under room temperature and low temperature regions including liquid hydrogen atmosphere. Low temperature toughness of welds was assessed particularly to identify characteristics of different welding methods developed newly for improvements. The stainless steels and the mother materials of aluminum alloy selected as the candidates have sufficient characteristics even under the liquid hydrogen atmosphere, but the welds have lower low-temperature toughness, requiring improvement. For the stainless steels, since the amount of {delta} ferrite in welds affects greatly the low-temperature toughness, adoption of complete austenite type welding metal is effective. The reduced pressure electron beam welding method can enhance drastically the low-temperature toughness of stainless steel. For the aluminum alloy, it can be one of the alternatives to use an alloy system with composition of high low-temperature toughness. The friction stir welding method for the aluminum alloy was found to provide extremely high low-temperature toughness, which can be evaluated as a new welding method. (NEDO)

The technical art `Bekko` is one of the traditional technologies in Japan, and the materials of `Bekko` are shells of hawksbills. However, the industry of `Bekko Work` has been facing a crisis recently, because the import of turtleshell is restricted. We have therefore tried to develop new materials as substitutes for the turtleshell by utilization of horn. The noteworthy aspects in this study are as follows: (a) It has been clearly established that the horn could be reformed with amber color similar to that of turtleshell by chemical treatment using hydrogen peroxide (H2O2). (b) It is also of interest that we produced new materials like `Bekko` by mixing horn powder and turtleshell powder at the appropriate ratio and molding them in the temperature range of 110-120{degree}C. 1 ref., 6 figs., 3 tabs.

Processing of a large amount of coal ash is a serious problem in considering the locational conditions of coal firing power generation plants. 46% of the coal ash was effectively used in 1985, and the remaining 54% was disposed at landfills on land and sea. Positive promotion of the effective use of coal ash is the necessity. A production method for an artificial lightweight aggregate utilizing coal ash was established by a joint research. The history of the research and development of this artificial lightweight aggregate (brand name: FA-lIGHT), outline of the manufacturing facilities, physical properties and result of use are introduced. The lightweight aggregates are used not only for the construction of multistoried buildings but also used as most suitable aggregates for making lightweight large scale panels and concrete secondary products such as lightweight blocks. FA-LIGHT is most suitable for use in the production of concrete lightweight aggregates, and can be used for hydroponic agriculture and for the improvement of drainage of land. Spread of its use is expected. 5 figs., 5 tabs.

Several kinds of silica gel modified by alkoxyalcohols were synthesized by refluxing and dehyration and the organic reactions were studied when these silica gels were used as the catalyst. It could be confirmed by FT-IR spectra, DTA and elementary analysis that alkoxylalcohols adhere to the surface of silica gels without any decomposition. The acetate was produced by using alkyl halides. It was found that the modified silica gels had clearly the catalytic action for the reaction with n-hexyl bromide and dibromoethane although unmodified silica gels did not show the catalytic action. The reducing reaction of carbonyl compounds was carried out. The reaction proceeded at 25 centigrade for acetophenone, cyclohexanone, 1-indanone and 2-octanone to produce the corresponding reduction products. 11 refs., 5 figs., 4 tabs.

Petropavlovsk-Kamchatky (P-K) city in Kamchatka, Russia is operating hot-water district heating using heavy oil boilers and waste hot water of thermal power plants as heat sources. Feasibility study was made on district heating using natural geothermal hot water and/or geothermal heat pump systems as heat sources of hot water supply for reduction of greenhouse effect gas emission. Among 3 areas including geothermal hot water, use of hot water in K area was impossible because of lower temperature and less spring water. Use of hot water in P and UP areas was impossible as primary hot water because of temperature drop to 64 degrees C during hot water supply toward P-K city. The building heating operation test was carried out using the geothermal heat pump system installed in a newly drilled heat exchange well of 100m deep. As a result, sufficient heat recovery was achieved for heating. If all of 49 boiler houses for heating are replaced with such geothermal heat pump systems, CO{sub 2} reduction was estimated to be 520,000t/y. (NEDO)

A research study was done on MHD generation by coal gasificating combustion. MHD generation is a very attractive power generation system such that efficiency is as high as 55%, that preservation of the environment is superior, and that coal can be used as fuel. The open cycle seems suitable for a one million kW class as a base load following up load fluctuation of approximately 20%, while the closed cycle for 200-300 thousand kW class doing daily start-stop. With a mind to a scale of 30 MWt, in the open cycle, R and D is required in such items as a coal gas combustor, generation channel, high temperature air heater, and seed/slag recovery device. In the closed cycle, R and D is required in the generation channel, high temperature helium heater/high temperature valve, seed injection/recovery device, operation technique of helium closed loop, etc..

Oil demand is expected to substantially grow in the future, and the use of oil with combustibles such as hull, baggase and waste is considered from an effective use of energy. A regional model survey was conducted as measures to reduce environmental loads where the fuel mixing combustion with coal and other energy is made the core. The domestic production amount of hull is 2.4-3.0 tons/year, which have a heating value of 3,500 kcal/kg. If hull can be formed into the one storable for a the long term (the one mixed with low grade coal, etc.), it can be a fuel for stable supply. Bagasse is produced 100 million tons/year, which have a heating value of 2,500 kcal/kg. Among wastes, waste tire, plastics, waste, sludge, etc. have a lot of problems in terms of price and environment, but each of them has a heating value during 3,000-10,000 kcal/kg. As to the coal combustion, the pollutional regulation on it is strict, and much higher processing technology is needed. The technology of coal fuel mixing combustion with other energy has not risen higher than the developmental level. Though the technology is a little bit higher in price than the coal fuel single combustion, it is viable. 38 refs., 32 figs., 65 tabs.

A development was intended of an alga reef block that is suitable for adherence of algae and difficult of shore-burning by utilizing coal ash. Concretes with different coal ash displacement rates were used to install alga reef blocks embedded with natural rocks, steel plates, and the used desulfurizing agents on three areas (the Usubetsu area, the Tamagawa offing, and Chatsu Bay) including shore-burned sea areas along the coast of Tomari Village. Investigations were made on the states of adherence of useful algae as a result of difference in materials and locations of installation. The best adherence of edible kelp was observed at the Usubetsu area, followed by the Tamagawa offing and Chatsu Bay in that order. Growth conditions of the kelp by locations were conceived of the correlation with how extensively the natural kelp colonies are formed around each location, and how many nutrient salts are present and sea urchins are grown. No remarkable difference was observed in the adherence of algae due to the difference in the coal ash displacement rates. Porous blocks, however, showed less adherence amount. Kelp adherence condition was found good in the order of concrete, natural rocks, and the used desulfurizing agents. No kelps have adhered on the steel plates. 10 refs., 13 figs., 3 tabs.

The utilization in Japan and abroad is discussed of desalination methods using evaporation, reverse osmosis (RO) membranes, and electrodialysis membranes, out of various desalination techniques for seawater and others containing more salt. A new seawater desalination plant built in Okinawa, Japan, is outlined, and the future trend of Japan`s efforts for desalination is predicted. The said plant in Okinawa is the largest ever built in this country, and occupies 4th or 5th place in terms of capacity among similar facilities across the world. It was completed in April, 1997, and produces pure water at a rate of 40,000m{sup 3}/day. This plant, operating on RO, comprises eight RO membrane units each capable of 5131{sup 3}/day. The membranes are of the spiral type, consisting of Toray`s crosslinked aramid-base composite membranes and Nitto Denko`s membranes composed totally of crosslinked aromatic polyamide. The greatest of the pending tasks is to reduce the desalination cost. As for the operating cost of the desalination facility at the current stage, it costs 120-130 yen/m{sup 3} on the 40,000m{sup 3}/day scale, and the power cost occupies approximately 60% of the total operating cost. It is concluded that the consumption of electric power and chemicals per pure water produced have to be reduced. 8 refs., 5 figs., 5 tabs.

For the river structures, such as slice gates and slice pipes, constructed on the weak ground, structures often come out due to forced settlement of embankment, which results in the formation of cavity and loose ground. These deformations can cause disasters due to leakage by water channel and fracture of bank. It is significant to detect and grasp these situations in early stage. In this study, resistivity imaging was conducted around slice gate in several times, to estimate the loose region based on the difference in the obtained resistivity data. Resistivity was measured in two times with a certain interval using the same line. The loose region around the slice gate was estimated from the change of saturation condition and the saturation line by considering the difference. Even in the case when judgment was hard by a single measurement, it was possible to estimate the loose region based on the difference from multiple measurements. 3 refs., 6 figs.

A study was conducted on a technology to melt shredder dust and non-combustible wastes directly by using coal, reduce their volume and re-utilize them. The elementary study on a high-temperature melting and treating technology set such targets as optimizing the melting and treating technology in correspondence with properties of materials to be treated, by using a small melting test plant, achieving a volume reduction rate of 1/200, and reducing treatment cost. In order to make innoxious the different kinds of environmental loading materials contained in exhaust gas from a high-temperature gasification and direct melting system, discussions were given on an optimum control condition for the exhaust gas system facilities. Furthermore, physical properties of discharges (slags nd metals) were investigated to discuss material re-utilization. In discussing optimal systems, three kinds of systems including two types utilizing fuels were proposed as high-temperature gasification and melting treatment process from a viewpoint of technology and cost. Respective systems were compared with each other on treatment cost, and their priorities were identified. 56 refs., 50 figs., 55 tabs.

This R and D project is aimed at stable production of high-quality, important machine members, which are difficult to sufficiently achieve the required properties by a single material, by carburization while minimizing use of expensive alloy metals, where high-temperature carburizing time is reduced by a plasma-aided system to save energy, and, at the same time, the conventional oil-hardening system is replaced by a He gas cooling/recycling system to solve the environmental problems involved in the former. The exhaust gases released from the plasma-aided system are adequately treated to prevent the problems caused thereby. The conditions of the plasma itself and treated surfaces are sensed in-situ, and the data are fed back to the process controlling system, to keep the treated object stable and high in quality, while minimizing energy consumption. The FY 1998 efforts were directed to studies on methods for sensing the plasma and treated surfaces, and specifications of a mini-plant for the demonstration tests, and to collection of characteristic data for development of some new products to be produced.

Described herein are the FY 1999 results of the feasibility study on the blast furnace top pressure recovery turbine (TRT) technology in China. Government of China is promoting the steel industry policies to weed out outdated, inefficient production systems while preparing the priority guidance list to promote introduction of advanced technologies, for which the government is implementing or planning the preferential measures, including exemption from the import taxes and VAT, and subsidization of interest on investment. This feasibility study predicts the commercial based investment in the case where the dry dust collector and TRT that are the principal components of a dry type TRT system are manufactured in China and its acquisition ratio is increased on the condition that a suitable number of the systems are installed and on the premise that a dissemination model project is implemented. The results indicate that the system can be introduced at a cost a little less than 60% of the predicted investment in the dissemination model project. The cost-effect ratio varies with power price, which widely varies by region in China, and the dissemination feasibility is studied over a wide range of power price. The system has high dissemination potential, because almost all of the Chinese steel makers will have a sufficient cost-effect ratio which satisfies their investment standards, if they are granted the preferential measures from the government.

Enzymatic and chemical methods were combined and methods were developed for synthesizing mucin type sugar chains and glycopeptides. The influence of sugar chain positions and structures on glycoconjugate stereo structures and physiological activities was analyzed, and glycopeptide structural activities and glycoconjugate remodelling were studied. To create an industrial advantage in a glycoprotein production system by use of zooblasts, sugar chain structure control through sugar transfase occurrence control was studied. For the production of man-adaptive sugar chains using yeast, new yeast variations were subjected to molecular breeding, and tested for the resultant improvement on productivity. Sugar chain marking and refining techniques and various responding mechanisms on the solid surface were elucidated, which enabled structure analyses using sugar chain recognition molecules such as lectins and antibodies. A database on interactions between sugar chains and sugar chain recognition molecules was constructed using the said findings. An analyzing program was also formulated tentatively. This paper also covers general surveys and studies on technologies of producing and utilizing glycoconjugates. (NEDO)

In developing hydrogen transportation and storage technologies based on the WE-NET project under the theme of the 'development of different common devices', surveys and discussions have been performed on four themes with high urgency. It was revealed that, with respect to the large liquid hydrogen pump, the survey report should be reported on the pump models, motors, reduction of NPSH, and bearings, and that the cryogenic pump technology has a necessity of further development because the technology is biased to pumps for rocket with high head. With regard to the vacuum heat-insulated piping with large diameters, such strict problems in the technological development were made clear as high heat insulating performance, optimization of the shield structure, measures for thermal stress, anti-seismic measures, and sealing mechanism at joints, in addition to the vacuum heat insulating piping technology that has been built to date. The liquid hydrogen valve is subjected to a technological problem of the very low temperature and combustion performances of liquid hydrogen, which requires further researches. With respect to the instrumentation facilities, as a result of discussing the liquid level meter system and the flow rate meter system, it was found that there is no almighty method, whereas selection of the method should be as required in particular situation.

The CASDAC (Containment And Surveillance Data Authenticated Communication) system has been developed by JAERI for nuclear safeguards and physical protection of nuclear material. This system was designed and constructed as an upgraded RECOVER system, design concept of which was based on the original RECOVER system and also the TRANSEAVER system. Both of them were developed several years ago as a remote monitoring system for continual verification of security and safeguards status of nuclear material. The system consists of two subsystems, one of them is a Grand Command Center (GCC) subsystem and the other is a facility subsystem. Communication between the two subsystems is controlled through the international telephone line network. Therefore all communication data are encrypted to prevent access by an unauthorized person who may intend to make a falsification, or tapping. The facility subsystem has an appropriate measure that ensure data security and reliable operation under unattended mode of operator. The software of this system is designed so as to be easily used in other different types of computers. This report describes the outline of the CASDAC system and the results of its performance test. This work has been carried out in the framework of Japan Support Programme for Agency Safeguards (JASPAS) as a project, JA-1. (author)

In relation to the circulating fluidized bed boiler which reduces the amount of sulfur oxides emitted in coal utilization, a verification project was carried out on installation of the equipment and spread activity in China and the Philippines contributing to the control of environmental pollutant associated with coal utilization and the effective use of energy. At the Fanshan area, installed was a 10t/h internal circulating fluidized bed boiler. At the performance test, coal includes around 7% of impurities such as stone, and the impurities should be excluded continuously at the time of actual run. Therefore, the boiler efficiency had to be changed from 89.5% to 85.8%. Further, power generation facilities have not yet been finished, and the overall operation of boiler turbine has not been executed. At the Zibo area, a 30t/h external circulating fluidized bed boiler was installed. The boiler efficiency reached 86.1%, over the targeted value. At the Batangas area in the Philippines, a 10t/h internal circulating fluidized bed boiler was installed. The boiler efficiency reached 85.8%, over the designed value. About the coal produced in the Philippines, slagging was feared, but the combustion state was favorable. 82 figs., 21 tabs.

Decisive parts of the Western political system have demonstrated a seemingly surprising misinterpretation of military might. As Madelaine Albright has suggested, the mighty perceived themselves as "almighty". Political power seems to have invested in instrumental coercive power relations and found...... military coercion to be the appropriate mean. Using the system theory and the theory of systemic risks displayed by the German sociologist Niklas Luhmann the article demonstrates how military systems due to their own autonomy and autopoiesis do not fit into the idea of political government....... The Clausewitzian ideal of a political system that could continue its power games by means of war was moderated by Clausewitz' own analysis of "friction". How can a political system be so blind towards the possibilities of another system? What are the risks of systemic blind spots? The argument of the paper...

Systems Biology is about combining theory, technology, and targeted experiments in a way that drives not only data accumulation but knowledge as well. The challenge in Systems Biomedicine is to furthermore translate mechanistic insights in biological systems to clinical application, with the central aim of improving patients' quality of life. The challenge is to find theoretically well-chosen models for the contextually correct and intelligible representation of multi-scale biological systems. In this review, we discuss the current state of Systems Biology, highlight the emergence of Systems Biomedicine, and highlight some of the topics and views that we think are important for the efficient application of Systems Theory in Biomedicine.

Study was made on creation of new functional inorganic materials under micro-gravity condition in an underground non-gravity experiment center to develop new production techniques of inorganic crystalline thin film, fine glass particle, anharmonic alloy, spherical semiconductor and surface modified semiconductor thin film. The micro-gravity observation result was analyzed numerically of interference fringes of Cu ion around an electrode during electrolysis. Experimental data relatively well agreed with computer simulation data. Prototype CdTe thin film was prepared by electrolysis. The size control condition of fine true spherical glass particles was clarified by micro-gravity evaporation/condensation of glass. Pb-Zn system alloys as an anharmonic alloy were prepared under micro-gravity condition, however, no compound of Pb and Zn was found. A production equipment of true spherical single-crystalline semiconductor by melting cubic Ge under micro-gravity condition, and basic data of heating condition were obtained. Surface modified semiconductor thin film was also obtained by micro-gravity laser annealing of SiGe prepared by plasma CVD. 23 refs., 65 figs., 6 tabs.

Search and assessment were carried out on innovative and leading technologies which are outside the development objects at the present, but are promising for the future. This paper describes the achievements in fiscal 2000. In the hydrogen manufacturing method using natural gas as the raw material, but not generating carbon dioxide, a method using plasma has the hydrogen conversion rate of more than 90%, capable of providing carbon black with added value. On a hydrogen selective enzyme hydrogenase sensor, verification was given on its sensitivity and response speed, but the discussion was interrupted because of difficulty in obtaining the enzyme. Naphthenic hydrogen storage and transportation media (easy in hydrogenation and dehydrogenation) were discussed, whereas the reaction promoting effect was identified in both of the super heating liquid film process and the membrane reactor system. Enhancement in output and efficiency may be anticipated if hydrogen-rich reformed gas is obtained by reforming methane (natural gas) by utilizing waste heat from a gas turbine of several MW capacity. Hydrogen liquefaction technologies using the magnetic freezing process was discussed as the fundamental research assignment, wherein fiscal 2000 has studied the basic design and optimal magnetic materials.

Hazardous wastes contaminated with radionuclides, chemicals, and explosives exist across the Department of Energy complex and need to be remediated due to environmental concerns. Currently, an opportunity is being developed to dramatically reduce remediation costs and to assist in the acceleration of schedules associated with these wastes by deploying a Hot Spot Removal System. Removing the hot spot from the waste site will remove risk driver(s) and enable another, more cost effective process/option/remedial alternative (i.e., capping) to be applied to the remainder of the site.

Hazardous wastes contaminated with radionuclides, chemicals, and explosives exist across the Department of Energy complex and need to be remediated due to environmental concerns. Currently, an opportunity is being developed to dramatically reduce remediation costs and to assist in the acceleration of schedules associated with these wastes by deploying a Hot Spot Removal System. Removing the hot spot from the waste site will remove risk driver(s) and enable another, more cost effective process/option/remedial alternative (i.e., capping) to be applied to the remainder of the site. The Hot Spot Removal System consists of a suite of technologies that will be utilized to locate and remove source terms. Components of the system can also be used in a variety of other cleanup activities.

A survey was made in relation with joint utilization of welfare device development data using an international network. Developing welfare devices requires data from ergonomic and medical systems, while the cope of the objects is wide, and the kinds are various. For proliferation of welfare devices, system compatibility evaluation including that on using environment is important, including living environments that are different by countries. The present survey has identified how data for aged, handicapped and help-needing persons are accumulated and utilized in research organizations in America and Europe for both of the ergonomic and medical areas. The survey also investigated major academic societies in overseas countries, and collected database and academic network information that support the advanced research and development. At the same time, investigations were also made on organizations and corporations who are moving forward the efficient data utilization. Welfare device and service information providing systems in Japan were investigated to compare them with the trends in other countries. Conceptions and methods were compiled to utilize data internationally and jointly. Database models for device development were considered, and a proposal was made on structuring a research and development supporting database, and the operation method thereof. (NEDO)

Research and development is conducted to collect intermediate products from Okinawan herbs for the production of antioxidant products usable for various purposes. Substance-producing plants are screened and the substances they offer are assessed for antioxidant activity, extracted, processed, prepared for market, and checked for safety. At the Okinawa Industrial Technology Center, a DPPH (1,1-diphenyl-2-picrylhydrazyl)/microplate method has been established, which promptly measures the antioxidant activity of the substances. Using this technology, the divisions concerned of industrial, academic, and governmental organizations cooperate with each other over the optimization of herb cultivation technology, development of a herbal ingredient analyzing technology, efficacy of herbs, development of a safety assessment system, development of a technology for the effective extraction, processing, and preparation of herbal ingredients, and the development of a technology of assessing antioxidant intermediate products for their efficacy. As the result, a technology is established of producing intermediate antioxidant products from Guava, Ryukyuyomogi, and Ukonisomatsu. They are unique Okinawan products, and sell at 40,000-50,000 yen. Since the prices are equal to or lower than the prices of other antioxidant intermediate products, probabilities are very high that they will get into markets in Japan proper. (NEDO)

System design in an evolving system-of-systems architecture and concept of operations

Science.gov (United States)

Rovekamp, Roger N., Jr.

Proposals for space exploration architectures have increased in complexity and scope. Constituent systems (e.g., rovers, habitats, in-situ resource utilization facilities, transfer vehicles, etc) must meet the needs of these architectures by performing in multiple operational environments and across multiple phases of the architecture's evolution. This thesis proposes an approach for using system-of-systems engineering principles in conjunction with system design methods (e.g., Multi-objective optimization, genetic algorithms, etc) to create system design options that perform effectively at both the system and system-of-systems levels, across multiple concepts of operations, and over multiple architectural phases. The framework is presented by way of an application problem that investigates the design of power systems within a power sharing architecture for use in a human Lunar Surface Exploration Campaign. A computer model has been developed that uses candidate power grid distribution solutions for a notional lunar base. The agent-based model utilizes virtual control agents to manage the interactions of various exploration and infrastructure agents. The philosophy behind the model is based both on lunar power supply strategies proposed in literature, as well as on the author's own approaches for power distribution strategies of future lunar bases. In addition to proposing a framework for system design, further implications of system-of-systems engineering principles are briefly explored, specifically as they relate to producing more robust cross-cultural system-of-systems architecture solutions.

This system enables a driver to park the car at a predetermined spot without the driver seeing the outside scene. The system shows on a driver seat display the steps that the driver is to follow and thereby supports the driver when visibility is poor, when the parking space is difficult to approach, when the driver is a novice, or when the driver is aged. The system ensures accurate positioning of the car by showing the steering direction and angle, the car speed, and the force of braking to the driver. For this purpose, the system knows the absolute car position by the use of an RFID (Radio Frequency Identification) tag which is a kind of IC (Integrated Circuit) card and D-GPS (Differential-Global Positioning System), grasps the relative car position by the use of a gyroscope, and collects data from plural sensors, which are complementary to each other, such as a car-speed sensor and a steering sensor.

Lewkowicz, Paul E.

Very large integrated systems have always posed special problems for engineers. Whether they are power generation systems, computer networks or space vehicles, whenever there are multiple interfaces, complex technologies or just demanding customers, the challenges are unique. 'Systems engineering' has evolved as a discipline in order to meet these challenges by providing a structured, top-down design and development methodology for the engineer. This paper attempts to define the general class of problems requiring the complete systems engineering treatment and to show how systems engineering can be utilized to improve customer satisfaction and profit ability. Specifically, this work will focus on a design methodology for the largest of systems, not necessarily in terms of physical size, but in terms of complexity and interconnectivity.

Highlights: • A novel solar cascade system using both trough and dish collectors is proposed. • Heat rejected by the Stirling engines is collected by the condensed water. • The directions to increase the efficiency improvement has been pointed out • Influence of flow type of heating/cooling fluids of Stirling engines is considered. - Abstract: This paper represents a novel solar thermal cascade system using both trough and dish systems for power generation. An effective structure using the condensed fluid of Rankine cycle to cool the Stirling engines to use the heat released by Stirling engines was proposed. The cascade system model with different fluid circuits was developed. The models of some important components of the system, such as dish collector, trough collector and Stirling engine array, are presented with detail explanation in this paper. Corresponding stand-alone systems were also developed for comparison. Simulations were conducted with the models to find out efficiency difference between cascade system and corresponding stand-alone systems. The directions to increase the efficiency difference were also considered. Results show that the cascade system can achieve a higher efficiency with a high solar irradiance (>550 W/m"2). The flow type of fluids between heating and cooling Stirling engine array is also required to concern on designing a cascade system with Stirling engine array.

Systems biology is today such a widespread discipline that it becomes difficult to propose a clear definition of what it really is. For some, it remains restricted to the genomic field. For many, it designates the integrated approach or the corpus of computational methods employed to handle the vast amount of biological or medical data and investigate the complexity of the living. Although defining systems biology might be difficult, on the other hand its purpose is clear: systems biology, with its emerging subfields systems medicine and systems pharmacology, clearly aims at making sense of complex observations/experimental and clinical datasets to improve our understanding of diseases and their treatments without putting aside the context in which they appear and develop. In this short review, we aim to specifically focus on these new subfields with the new theoretical tools and approaches that were developed in the context of cancer. Systems pharmacology and medicine now give hope for major improvements in cancer therapy, making personalized medicine closer to reality. As we will see, the current challenge is to be able to improve the clinical practice according to the paradigm shift of systems sciences.

Reynolds, Martin; Holwell, Sue

Each of the five systems approaches discussed in this volume: system dynamics (SD), the viable systems model (VSM), strategic options development and analysis (SODA), soft systems methodology (SSM) and critical systems heuristics (CSH) has a pedigree. Not in the sense of the sometimes absurd spectacle of animals paraded at dog shows. Rather, their pedigree derives from their systems foundations, their capacity to evolve and their flexibility in use. None of the five approaches has developed out of use in restricted and controlled contexts of either low or high levels of complicatedness. Neither has any one of them evolved as a consequence of being applied only to situations with either presumed stakeholder agreement on purpose, or courteous disagreement amongst stakeholders, or stakeholder coercion. The compilation is not a celebration of abstract ‘methodologies', but of theoretically robust approaches that have a genuine pedigree in practice.

Complex Adaptive Systems of Systems, or CASoS, are vastly complex physical-socio-technical systems which we must understand to design a secure future for the nation. The Phoenix initiative implements CASoS Engineering principles combining the bottom up Complex Systems and Complex Adaptive Systems view with the top down Systems Engineering and System-of-Systems view. CASoS Engineering theory and practice must be conducted together to develop a discipline that is grounded in reality, extends our understanding of how CASoS behave and allows us to better control the outcomes. The pull of applications (real world problems) is critical to this effort, as is the articulation of a CASoS Engineering Framework that grounds an engineering approach in the theory of complex adaptive systems of systems. Successful application of the CASoS Engineering Framework requires modeling, simulation and analysis (MS and A) capabilities and the cultivation of a CASoS Engineering Community of Practice through knowledge sharing and facilitation. The CASoS Engineering Environment, itself a complex adaptive system of systems, constitutes the two platforms that provide these capabilities.

The paper described the fiscal 1997 result of the study of scenarios for introducing hydrogen to the urban area. In the case of studying it in London, it was found that hythane (mixture of hydrogen into town gas) was effective, but in the case of doing in Tokyo, it was found that the scenario was undesirable because of the increasing infracost. Accordingly, another scenario was studied. It was assessed from the aspects of environmental advantages, infracosts, and potential advantageous values in urban areas associated with hydrogen utilization (hydrogen premium). It is most effective to use hydrogen as a fuel of transportation means from the aspect of environmental merits as the decrease in external cost. In Tokyo, the dependence upon electric power is large, and therefore it is attractive to introduce highly efficient fuel cells which enable the dispersed cogeneration using hydrogen. The value of hydrogen is determined by the avoidance of environmentally influential substances and the surplus generated output by fuel cells (substitution for the existing natural gas). When the high external cost can be assumed, the value of hydrogen becomes large. The paper also considered the arrangement of infrastructures in Tokyo. 187 refs., 14 figs., 18 tabs.

System integration (SI) is defined as combining hardwares and softwares as the infrastructures with know-hows for their use comprehensively to respond to high-level needs of users. This paper reports the features of an SI being developed by a company (E Company), its concept on the systematized development methodology, and the conceptual models. With the primary policy placed on creative integration standing on customers positions, the SI concept comprises three parts of models for evaluations as seen from the customers, evaluations as seen from the E Company, and the development object systems to link both parts. The third part is further consisted of several lower hierarchies including a customer controlled system hierarchy (this enables customers to control the system through visualization, for example, and includes three logic models (multiple solution selection, optimal solution under restricted conditions, and numerical solution)). 2 refs., 9 figs.

Fiscal system analysis - contractual systems

Production sharing contracts are one of the most popular forms of contractual system used in petroleum agreements around the world, but the manner in which the fiscal terms and contract parameters impact system measures is complicated and not well understood. The purpose of this paper is to quantify the influence of private and market uncertainty in contractual fiscal systems. A meta-modelling approach is employed that couples the results of a simulation model with regression analysis to construct numerical functionals that quantify the fiscal regime. Relationships are derived that specify how the present value, rate of return, and take statistics vary as a function of the system parameters. The deepwater Girassol field development in Angola is taken as a case study. (author)

System Entropy Measurement of Stochastic Partial Differential Systems

Directory of Open Access Journals (Sweden)

Bor-Sen Chen

2016-03-01

Full Text Available System entropy describes the dispersal of a system’s energy and is an indication of the disorder of a physical system. Several system entropy measurement methods have been developed for dynamic systems. However, most real physical systems are always modeled using stochastic partial differential dynamic equations in the spatio-temporal domain. No efficient method currently exists that can calculate the system entropy of stochastic partial differential systems (SPDSs in consideration of the effects of intrinsic random fluctuation and compartment diffusion. In this study, a novel indirect measurement method is proposed for calculating of system entropy of SPDSs using a Hamilton–Jacobi integral inequality (HJII-constrained optimization method. In other words, we solve a nonlinear HJII-constrained optimization problem for measuring the system entropy of nonlinear stochastic partial differential systems (NSPDSs. To simplify the system entropy measurement of NSPDSs, the global linearization technique and finite difference scheme were employed to approximate the nonlinear stochastic spatial state space system. This allows the nonlinear HJII-constrained optimization problem for the system entropy measurement to be transformed to an equivalent linear matrix inequalities (LMIs-constrained optimization problem, which can be easily solved using the MATLAB LMI-toolbox (MATLAB R2014a, version 8.3. Finally, several examples are presented to illustrate the system entropy measurement of SPDSs.

Daylight responsive dimming systems have been used in few buildings to date because they require improvements to improve reliability. The key underlying factor contributing to poor performance is the variability of the ratio of the photosensor signal to daylight workplane illuminance in accordance with sun position, sky condition, and fenestration condition. Therefore, this paper describes the integrated systems between automated roller shade systems and daylight responsive dimming systems with an improved closed-loop proportional control algorithm, and the relative performance of the integrated systems and single systems. The concept of the improved closed-loop proportional control algorithm for the integrated systems is to predict the varying correlation of photosensor signal to daylight workplane illuminance according to roller shade height and sky conditions for improvement of the system accuracy. In this study, the performance of the integrated systems with two improved closed-loop proportional control algorithms was compared with that of the current (modified) closed-loop proportional control algorithm. In the results, the average maintenance percentage and the average discrepancies of the target illuminance, as well as the average time under 90% of target illuminance for the integrated systems significantly improved in comparison with the current closed-loop proportional control algorithm for daylight responsive dimming systems as a single system.

With an intention to establish a technology required to build a hydrogen storage tank with a storage capacity of 50,000 m{sup 3} as the target shown in the basic plan for WE-NET, the current fiscal year has performed the technical literature surveys to identify the existing technologies. In the survey on the similar large storage system, a liquefied natural gas (LNG) was taken up, and the survey on the LNG bases in Japan was carried out. With regard to the existing liquefied hydrogen storage system, surveys were performed on the test site for developing the liquefied hydrogen/liquefied oxygen engines, the rocket launch sites, and liquefied hydrogen manufacturing plant. In relation with peripheral technologies for the underground storage tank being an excellent anti-seismic form, the LNG underground storage facilities were surveyed. Regarding the rock mass storage tank, surveys were carried out on the LPG rock mass storage having been used practically, and the LNG rock mass storage that is in the demonstration phase. In the research on storage facilities, surveys were executed on the forms and heat insulation structures of the similar large low-temperature storage tanks, the use record of the existing liquefied hydrogen storage tanks, heat insulating materials, and heat insulating structures.

Amotosalen: Allogeneic Cellular Immunotherapies system, INTERCEPT Plasma System, INTERCEPT Platelet System, S 59.

Science.gov (United States)

2003-01-01

Adis CommentsCerus Corporation is developing a variety of pathogen-inactivation systems, based on its Helinx technology. Three of the systems include amotosalen [S 59] as the inactivation compound. Amotosalen is a light-activated, DNA-, RNA-crosslinking psoralen compound, which is used to neutralise pathogens. The systems that utilise amotosalen are called the INTERCEPT Platelet System, the INTERCEPT Plasma System and the Allogeneic Cellular Immunotherapies (ACIT) system. The INTERCEPT Platelet System and INTERCEPT Plasma System are two of the systems that make up Cerus' INTERCEPT Blood Systems. The other system is the INTERCEPT Red Blood Cell System, which contains S 303 as the inactivation compound rather than amotosalen. Cerus' Helinx technology is able to prevent replication of DNA or RNA that is present in pathogens but not in the blood components being treated (e.g. platelets and plasma). When added to the blood components, the inactivation agent (in this case amotosalen) crosses the membrane or cell wall of the pathogen. When activated by light, amotosalen binds to the nucleic acid of the pathogen and prevents replication. This process prevents infection. INTERCEPT Platelet System: Cerus developed its INTERCEPT Platelet System, in collaboration with Baxter Healthcare, for use in blood centres. Platelets are an essential component of the coagulation process and may be required by patients undergoing surgery, cancer chemotherapy, transplantation or with bleeding disorders. The system is made up of an illuminator device, a compound absorption device and a processing kit containing amotosalen. In October 2002, the two companies announced that CE Mark approval had been received for the illuminator device for the INTERCEPT trade mark Blood System. Application of this technology to platelets is the first to be approved. As it is a new technology, the system is currently undergoing process validation in accordance with European Blood Bank GMP requirements. This

Today’s electricity grid is the most complex system ever built—and the future grid is likely to be even more complex because it will incorporate distributed energy resources (DERs) such as wind, solar, and various other sources of generation and energy storage. The complexity is further augmented by the possible evolution to new retail market structures that provide incentives to owners of DERs to support the grid. To understand and test new retail market structures and technologies such as DERs, demand-response equipment, and energy management systems while providing reliable electricity to all customers, an Integrated Energy System Model (IESM) is being developed at NREL. The IESM is composed of a power flow simulator (GridLAB-D), home energy management systems implemented using GAMS/Pyomo, a market layer, and hardware-in-the-loop simulation (testing appliances such as HVAC, dishwasher, etc.). The IESM is a system-of-systems (SoS) simulator wherein the constituent systems are brought together in a virtual testbed. We will describe an SoS approach for developing a distributed simulation environment. We will elaborate on the methodology and the control mechanisms used in the co-simulation illustrated by a case study.

The application of photonics in space systems requires tight integration with the spacecraft systems to ensure accurate operation. This requires some detailed and specific system engineering to properly incorporate the photonics into the spacecraft architecture and to guide the spacecraft architecture in supporting the photonics devices. Recent research in product focused, elegant system engineering has led to a system approach which provides a robust approach to this integration. Focusing on the mission application and the integration of the spacecraft system physics incorporation of the photonics can be efficiently and effectively accomplished. This requires a clear understanding of the driving physics properties of the photonics device to ensure proper integration with no unintended consequences. The driving physics considerations in terms of optical performance will be identified for their use in system integration.

Full Text Available A nonlinear robust control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving nominal system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear system over a prescribed range of system uncertainty by robustly stabilizing a collection of nonlinear controlled uncertain subsystems. The robust switching nonlinear controller architecture is designed based on a generalized (lower semicontinuous Lyapunov function obtained by minimizing a potential function over a given switching set induced by the parameterized nominal system equilibria. The proposed framework robustly stabilizes a compact positively invariant set of a given nonlinear uncertain dynamical system with structured parametric uncertainty. Finally, the efficacy of the proposed approach is demonstrated on a jet engine propulsion control problem with uncertain pressure-flow map data.

The numerical analysis program based on the difference method for dynamics of sea water with sea-surface displacement, flow rate, salt content and temperature as the parameters is modified to more accurately assess the effects of a huge marine structure on surrounding environment by adding the effects of insolation and boundary conditions of the sea-covering effects of the floating structure. The numerical simulation was done for summer and winter seasons, not in a sea area but using a rectangular bay with the floating structure at the center. A new flow evolves around the floating structure, due to the sea-covering effect. The flow patterns in summer and winter are clearly different, due to difference in insolation. The predicted flow is also sensitive whether stratification is considered or not, by which is meant that it is important what stratification effect is taken into account. Daily insolation changes are accompanied by vertical distribution of water temperature and its temporal change. These effects are also observed under the floating structure which shields insolation. 10 refs., 17 figs., 4 tabs.

Mitsui Kushikino Mine previously processed two gold ores from Kushikino and Iwato ore deposits by the all slime cyanidation method, where the ores were ground to fine size smaller than 75 {mu}m and leached with sodium, cyanide. A large amount of slimes were produced as waste and discarded in tailings ponds. To save the costs of grinding and waste treatment it is desirable to process coarse sized ores. The Iwato ore is gold and silver bearing silicified porous rock. As most gold and silver in the Iwato ore are concentrated in the pores, leaching of coarse sized ore is expected to be possible. Laboratory tests and pilot plant tests of vat leaching for the Iwato ore were carried out using 0.15-8.0 mm feed. These results showed that the gold dissolution rate was similar to that by the all slime cyanidation and the decrease in gold recovery was a few %. The properties of these tailings can be used in fine aggregate of concrete. Based on the results vat leaching of the Iwato ore was adopted in the plant. The tailings are sold and used as fine aggregate. Utilization of slime tailings from the other ores was also developed and they are used as flux in copper smelters. Now, there is no tailings pond at Mitsui Kushikino Mine. 9 refs., 10 figs., 5 tabs.

To reduce SOx with coal utilization, a desulfurizer is introduced in Thailand as diffusion activities in the demonstration program. The purpose is to reduce the environmental pollutants. For this desulfurizer, lime mud mainly composed of lime stone is used as an absorber. SO2 in the flue gas is absorbed by the slurry of lime mud, to form calcium sulfite. The calcium sulfite blown in the bottom of recycling tank is oxidized by oxygen in the air, to form gypsum. The gypsum is recovered as a by-product. In this fiscal year, a feeder of lime stone, spray nozzles, and various analysis apparatuses were supplied. Supervisors for electric instrumentation/control were also dispatched as well as for main body construction, to carry out the instrumentation setting works, check of sequences, and adjustment of apparatuses. After the test operation, supervisors for the demonstration operation were dispatched up to March 1998, to conduct the cooperation works between Japan and Thailand sides. Thus, successful and successive demonstration operation was confirmed. 21 figs., 6 tabs.

As a WE-NET subtask, a study has been conducted of the solid polyelectrolyte water electrolysis method by which higher efficiency and lower cost hydrogen production is expected than in the conventional hydrogen production method. Production methods of electrode, electrolyte, etc. were studied. In the electroless plating method, the manufacturing process of membrane-electrode assemblies was realized in a large area of 2500 cm{sup 2} by the porous-surfaced method by studying manufacturing conditions for slurry membrane/membrane assembly/electroless plating processes. In the hot-press method, the refining degree and dispersibility of iridium dioxide powder were studied to improve characteristics of anode catalyst. A method was developed to form polyelectrolyte coatings homogeneously on the surface of electrode layer catalytic powder, and a large area of 2500 cm{sup 2} was realized. Beside the performance test using large single cells, FS was conducted to discuss optimum operating conditions and optimum structures of plants. Both methods indicated the performance exceeding the energy conversion efficiency of 90%, a WE-NET target, at current density of 1A/cm{sup 2} and electrolysis temperature of 80degC. A key was found to a bench-scale development (electrode area of 2500 cm{sup 2}, about 5 layers) to be planned in fiscal 1998. 136 figs., 50 tabs.

Studies are conducted about the feasibility of the above-named technology in China, its energy conservation and environmental protection effects, and so forth. To be expected upon conversion of shaft kilns in China to fluidized bed kilns using this technology are energy conservation of approximately 30%; resultant reduction in greenhouse effect gas emissions, in the scattering of coarse particulates, and in NOx and SOx emissions, these in combination contributing to reduction in environmental pollution; stable production of high-quality clinker; preference to inexpensive fuels and the effective utilization of resources; reduction in the cement manufacturing cost; and so forth. On-site surveys were conducted at existing shaft kiln plants, and studies were made about conversion to fluidized bed cement kilns with a 1,000 tons/day capability. The conclusion was that the period of return on invested capital would be 3.94-8.98 years, dependent upon the degree of facilities renovation, showing the presence of high possibilities of a successful return on invested capital. It was estimated that the shaft kilns would bring about a yearly reduction of 840 tons of coarse particulates, 105 tons of SO{sub 2}, and 68,281 tons of CO2. (NEDO)

This paper describes the demonstrative project for coal preparation technology, as a part of the measures against environmental pollution due to the structuring of demonstration and dissemination basis for clean coal technologies in China, The results for fiscal 1999 is reported. In the utilization of coal in China, a problem of urgency is the highly efficient selection and removal of sulfur contents in raw coal. Coal production in Chongquing City is yearly 30 million tons, of which 90% contains sulfur contents of 3% or higher. At Jinjia Colliery of Panjiang Coal and Electric Co. Ltd., Guizhou Province, a site for the present project, a number of coal seams are unsuitable for single utilization because of high sulfur contents. The coal preparation technologies to be introduced are expected to improve coal preparation efficiency and desulfurization ratio in terms of both the washability of raw coal and the accuracy of the coal washer. This is the third year of the project, with the following activities performed, namely, research/design, manufacturing/procurement of equipment, design for construction work, training of operators or the like, and documentation. The manufacturing and procurement are for such equipment as vacuum disk filter with accessories, waste water thickener, pressure filter for tailings with accessories, flocculant pump/piping, slurry tank/pump, high-shear mixer with accessories, and electric instrumentation. All the equipment arrived at the site in January, 2001. (NEDO)

An environmentally friendly refuse energy utilizing business, for which RDF (refuse derived fuel) produced out of wastes discharged by industries belonging to a Fujieda city environmental protection council will provide the heat source, is proposed by the said council. The proposal is subjected to a study, a basic plan is drafted, and a decision is made on its profitability. In the study, surveys are conducted on the actualities of wastes and of demand for heat, and specifications are worked out relating to transportation and storage of RDF, production of steam by an RDF-fired boiler, routing of pipes for transmitting the steam to the industries in the district, facility costs, operating costs, etc. It is found that the amount of RDF produced out of the wastes discharged by the council member industries is so small that it can meet the demand of only one industry and that, even if more wastes are collected from a wider area, the increased amount will but meet the demand of two industries and a hot water pool. It is found that the system will be economically feasible, however, if the shortage of RDF-generated energy is covered by an oil-fired boiler and thereby impartiality is established in steam distribution and steam production unit price is reduced. In view of the intensification of control over dioxin, etc., the business will be gaining profit in 2002 and after. (NEDO)

Sail GTS ground system analysis: Avionics system engineering

A comparison of two different concepts for the guidance, navigation and control test set signal ground system is presented. The first is a concept utilizing a ground plate to which crew station, avionics racks, electrical power distribution system, master electrical common connection assembly and marshall mated elements system grounds are connected by 4/0 welding cable. An alternate approach has an aluminum sheet interconnecting the signal ground reference points between the crew station and avionics racks. The comparison analysis quantifies the differences between the two concepts in terms of dc resistance, ac resistance and inductive reactance. These parameters are figures of merit for ground system conductors in that the system with the lowest impedance is the most effective in minimizing noise voltage. Although the welding cable system is probably adequate, the aluminum sheet system provides a higher probability of a successful system design.

Physical analogs have shown considerable promise for understanding the behavior of complex adaptive systems, including macroeconomics, biological systems, social networks, and electric power markets. Many of today's most challenging technical and policy questions can be reduced to a distributed economic control problem. Indeed, economically based control of large-scale systems is founded on the conjecture that the price-based regulation (e.g., auctions, markets) results in an optimal allocation of resources and emergent optimal system control. This report explores the state-of-the-art physical analogs for understanding the behavior of some econophysical systems and deriving stable and robust control strategies for using them. We review and discuss applications of some analytic methods based on a thermodynamic metaphor, according to which the interplay between system entropy and conservation laws gives rise to intuitive and governing global properties of complex systems that cannot be otherwise understood. We apply these methods to the question of how power markets can be expected to behave under a variety of conditions.

The implementation of an integrated system health management (ISHM) capability is fundamentally linked to the management of data, information, and knowledge (DIaK) with the purposeful objective of determining the health of a system. It is akin to having a team of experts who are all individually and collectively observing and analyzing a complex system, and communicating effectively with each other in order to arrive at an accurate and reliable assessment of its health. In this paper, concepts, procedures, and approaches are presented as a foundation for implementing an intelligent systems ]relevant ISHM capability. The capability stresses integration of DIaK from all elements of a system. Both ground-based (remote) and on-board ISHM capabilities are compared and contrasted. The information presented is the result of many years of research, development, and maturation of technologies, and of prototype implementations in operational systems.

Villaran, M.; Subudhi, M.

1989-01-01

As part of ongoing efforts to understand and manage the effects of aging in nuclear power plants, an aging assessment was performed for the Instrument Air (IA) system, a system that has been the subject of much scrutiny in recent years. Despite its non-safety classification, instrument air has been a factor in a number of potentially serious events. This report presents the results of the assessment and discusses the impact of instrument air system aging on system availability and plant safety. This work was performed for the US Nuclear Regulatory Commission (NRC) as part of the Nuclear Plant Aging Research (NPAR) program. To perform the complex task of analyzing an entire system, the Aging and Life Extension Assessment Program (ALEAP) System Level Plan was developed by Brookhaven National Laboratory and applied successfully in previous system aging studies. The work presented herein was performed using two parallel work paths, as described in the ALEAP plant. One path used deterministic techniques to assess the impact of aging on compressed air system performance, while the second path used probabilistic methods. Results from both paths then were used to characterize aging in the instrument air system. Some conclusions from this work are: compressors, air system valves, and air dryers were found to make up the majority of failures; the effectiveness and quantity of preventive maintenance devoted to a component significantly affected the amount of failures experienced; review of compressed air system designs and studies using a PRA-based system model revealed that the redundancy of key components (compressors, dryers, IA/SA crossconnect valve) was an important factor in system availability; total loss of air events are uncommon

This document provides both functional and physical descriptions of a conceptual high-level waste management system defined as a Basic MRS System. Its purpose is to provide a basis for required system computer modeling and system studies initiated in FY 1990 under the Systems Integration Program of the Office of Civilian Radioactive Waste Management Office (OCRWM). Two specific systems studies initiated in FY 1990, the Reference System Performance Evaluation and the Aggregate Receipt Rate Study, utilize the information in this document. The Basic MRS System is the current OCRWM reference high-level radioactive wastes repository system concept. It is designed to accept 3000 MTU per year of spent fuel and 400 equivalent MTU per year of high-level wastes. The Basic MRS System includes a storage-only MRS that provides for a limited amount of commercial spent fuel storage capacity prior to acceptance by the geologic repository for disposal. This document contains both functional descriptions of the processes in the waste management system and physical descriptions of the equipment and facilities necessary for performance of those processes. The basic MRS system contains all system components, from the waste storage facilities of the waste generators to the underground facilities for final disposal of the wastes. The major facilities in the system are the waste generator waste storage facilities, an MRS facility that provides interim storage wastes accepted from the waste generators, a repository facility that packages the wastes and then emplaces them in the geologic repository, and the transportation equipment and facilities for transporting the waste between these major facilities

A business feasibility survey was performed on introduction of an RDF electric power generation system utilizing general wastes in the Noto area. Wastes quantity was estimated by accounting for large-sized wastes to be generated newly as a result of enforcement of the container package recycling law, and transfer of non-combustible wastes to incineration. The quantity was estimated to be 84,000 tons annually. Quantities of RDF and heat were calculated from this estimation to be 103 tons per day and 400 lkcal/kg respectively. According to the result of discussing the RDF transportation systems, time-based freight was found advantageous for short distance, and distance freight system for long distance in terms of cost. Discussions for RDF power systems were carried out on an RDF circulation fluid bed furnace plus ash melting furnace, a fluid bed gasification melting furnace, and shaft furnace type gasification melting furnace. In a comprehensive view, it is difficult to distinguish them in terms of merit and demerit. Molten slag was assumed to be re-utilized, but cost for the re-utilization should be considered. According to the result of discussing the business feasibility, it was found difficult to make it profitable by operating the RDF power generation business alone, and wastes incineration charge should be collected.

Verification and Validation Issues in Systems of Systems

Eric Honour

2013-11-01

Full Text Available The cutting edge in systems development today is in the area of "systems of systems" (SoS large networks of inter-related systems that are developed and managed separately, but that also perform collective activities. Such large systems typically involve constituent systems operating with different life cycles, often with uncoordinated evolution. The result is an ever-changing SoS in which adaptation and evolution replace the older engineering paradigm of "development". This short paper presents key thoughts about verification and validation in this environment. Classic verification and validation methods rely on having (a a basis of proof, in requirements and in operational scenarios, and (b a known system configuration to be proven. However, with constant SoS evolution, management of both requirements and system configurations are problematic. Often, it is impossible to maintain a valid set of requirements for the SoS due to the ongoing changes in the constituent systems. Frequently, it is even difficult to maintain a vision of the SoS operational use as users find new ways to adapt the SoS. These features of the SoS result in significant challenges for system proof. In addition to discussing the issues, the paper also indicates some of the solutions that are currently used to prove the SoS.

Full Text Available Systems theory is product of the efforts of many researchers to create an intermediate field of coexistence of all sciences. If not for anything else, because of the magnitude that the use of systemic thinking and systemic approach has taken, it has become undisputed among the theories. Systems theory not only provides a glossary of terms with which researchers from different fields can be understood, but provides a framework for the presentation and interpretation of phenomena and realities. This paper addresses a systematic approach to leadership, as an attempt to dredge leadership and systems theory literature to find the meeting point. Systems approach is not an approach to leadership in terms of a manner of leader’s work, but it’s the leader's determination to factorize in his leadership the external environment and relationships with and among elements. Leader without followers is unable to exercise his leadership and to ensure their conviction he should provide a system, a structure, a purpose, despite the alternative chaos. Systems approach clarifies the thought on the complexity and dynamism of the environment and provides a framework for building ideas. If the general system theory is the skeleton of science (Boulding: 1956, this article aims to replenish it with leadership muscles by prominent authors who have written on systems theory and leadership, as well as through original ideas. In this work analytical methods were used (by analyzing approaches individually as well as synthetic methods (by assaying individual approaches in context of entirety. The work is a critical review of literature as well as a deductive analysis mingled with models proposed by authors through inductive analysis. Meta-analysis has been used to dissect the interaction and interdependence between leadership approaches.

Siemieniuch, C E; Sinclair, M A

2006-01-01

The paper presents a view of systems integration, from an ergonomics/human factors perspective, emphasising the process of systems integration as is carried out by humans. The first section discusses some of the fundamental issues in systems integration, such as the significance of systems boundaries, systems lifecycle and systems entropy, issues arising from complexity, the implications of systems immortality, and so on. The next section outlines various generic processes for executing systems integration, to act as guides for practitioners. These address both the design of the system to be integrated and the preparation of the wider system in which the integration will occur. Then the next section outlines some of the human-specific issues that would need to be addressed in such processes; for example, indeterminacy and incompleteness, the prediction of human reliability, workload issues, extended situation awareness, and knowledge lifecycle management. For all of these, suggestions and further readings are proposed. Finally, the conclusions section reiterates in condensed form the major issues arising from the above.

The solar power satellite system is a system that converts solar energy into electric energy in the space, transmits power to earth through wireless resort such as microwave and supplies energy of new concept. In order to realize this system it is necessary to have new technologies such as space power transmission at low cost, construction of large space buildings and wireless high power transmission. In this paper, the principles, characteristics and the necessary technology of this system were explained. Besides Japan`s SPS2000 Plan (cooperative research by universities, government agencies and private corporations on the model of solar power satellite) the group of Europe, Russia and the United States has also proposed some ideas concerning the solar power satellite system. As far as the microwave power transmission, which is the key technology for solar power satellite system, is concerned, ground demonstration tests at the level of several tens of kW are discussed in Canada and France. 3 refs., 3 figs.

International Nuclear Information System (INIS)

Krantz, E.A.; Russell, K.D.; Stewart, H.D.; Van Siclen, V.S.

1986-01-01

Utilization of Probabilistic Risk Assessment (PRA) related information in the day-to-day operation of plant systems has, in the past, been impracticable due to the size of the computers needed to run PRA codes. This paper discusses a microcomputer-based database system which can greatly enhance the capability of operators or regulators to incorporate PRA methodologies into their routine decision making. This system is called the System Analysis and Risk Assessment (SARA) system. SARA was developed by EG and G Idaho, Inc. at the Idaho National Engineering Laboratory to facilitate the study of frequency and consequence analyses of accident sequences from a large number of light water reactors (LWRs) in this country. This information is being amassed by several studies sponsored by the United States Nuclear Regulatory Commission (USNRC). To meet the need of portability and accessibility, and to perform the variety of calculations necessary, it was felt that a microcomputer-based system would be most suitable

Decision makers increasingly rely on large-scale computational models to simulate and analyze complex man-made systems. For example, computational models of national infrastructures are being used to inform government policy, assess economic and national security risks, evaluate infrastructure interdependencies, and plan for the growth and evolution of infrastructure capabilities. A major challenge for decision makers is the analysis of national-scale models that are composed of interacting systems: effective integration of system models is difficult, there are many parameters to analyze in these systems, and fundamental modeling uncertainties complicate analysis. This project is developing optimization methods to effectively represent and analyze large-scale heterogeneous system of systems (HSoS) models, which have emerged as a promising approach for describing such complex man-made systems. These optimization methods enable decision makers to predict future system behavior, manage system risk, assess tradeoffs between system criteria, and identify critical modeling uncertainties.

MARBLE: A system for executing expert systems in parallel

Science.gov (United States)

Myers, Leonard; Johnson, Coe; Johnson, Dean

1990-01-01

This paper details the MARBLE 2.0 system which provides a parallel environment for cooperating expert systems. The work has been done in conjunction with the development of an intelligent computer-aided design system, ICADS, by the CAD Research Unit of the Design Institute at California Polytechnic State University. MARBLE (Multiple Accessed Rete Blackboard Linked Experts) is a system of C Language Production Systems (CLIPS) expert system tool. A copied blackboard is used for communication between the shells to establish an architecture which supports cooperating expert systems that execute in parallel. The design of MARBLE is simple, but it provides support for a rich variety of configurations, while making it relatively easy to demonstrate the correctness of its parallel execution features. In its most elementary configuration, individual CLIPS expert systems execute on their own processors and communicate with each other through a modified blackboard. Control of the system as a whole, and specifically of writing to the blackboard is provided by one of the CLIPS expert systems, an expert control system.
