    Various energy-related issues were analyzed in a many-sided and compound manner; and as their solutions, various combined systems were examined on the assumption that functional mediums, core technology and regional district characteristics were utilized; and an explanation was given in the case of using hydrogen as an energy medium. Hydrogen was a strong candidate capable of securing toughness in energy flow; and an idea was shaped about introducing hydrogen by steps before structuring a hydrogen society that is to replace the petroleum society. In the case of introducing a hydrogen energy medium into an intelligent building, the characteristics would be such that it is a highly efficient system capable of supplying energy in the form of electric power, hydrogen and heat, that it brings in a function for leveling a load of electric power, that it facilitates consistency with each energy in various uses, and that it is capable of dealing with a demand for hydrogen energy which is expected to increase in the future. It is highly probable that the system will become an attractive one in view of environment and social economy. 8 refs., 4 figs.

  3. Radiobiologic response of CHO-KI cells treated with vitamin A

    International Nuclear Information System (INIS)

    Treatment of CHO-KI cells with vitamin A altered their response to subsequent gamma irradiation. In general longterm preincubation with low doses of the vitamin caused a relative increase in the number of cells surviving a given radiation dose. The effect resulted in an increase in the D0 of the survival curve. Long or short term exposure to high concentrations of the vitamin caused a decrease in the number of surviving cells leading to a decrease in the extrapolation number of the survival curve. Recovery of cells from radiation damage, assessed using the split dose technique, was also impaired by vitamin A pretreatment. A mechanism involving repair of potentially lethal damage may explain the protective effect of vitamin A since this was highly dependent on the cell density of cultures at the time of irradiation. However, in view of the data showing that the vitamin A concentrations necessary to alter the radiation survival curve shoulder caused a significant release of sialic acid into the medium, a mechanism involving membrane stability may account for both the reduction in repair/recovery capacity of the treated cells and the radioprotective effect.

    This paper summarizes the research result in fiscal 1997 from the basic research results on the commercialization of innovative energy technologies. The target of a photovoltaic power generation market includes isolated power sources (several kWp) for distant places or developing countries, and those (several tens kWp) for personal residences or public facilities. Although the former is mainly promoted in the West, while the latter over the world, their profitability is unsolved. Power plants over several hundreds kWp are in demonstration test. Solar heat power generation of several tens to hundreds MWp is most profitable, however, small-scale one is poor in feasibility. Australia takes an interest in distributed photovoltaic power generation directly connected with actual lives of residents, and has a dominant opinion that desert is useless as large-scale site. This country lays emphasis on protection and maintenance rather than positive use of desert based on a basic cognition that desert is easily changed and broken. The Australian government announced power company`s obligation to use renewable energy by 2%, and a strong organization is scheduled to be newly established. 59 figs., 57 tabs.

    For the comprehensive and rational evaluation of technologies related to new energy and energy saving, investigations have been conducted about the history and trend of related policies and technological development. Japan saw a great change in the demand-supply structure in 10 to 15 years following the first oil crisis when oil was partially replaced with atomic energy and LNG and energy-saving efforts came into practice. However, the diversification of energy sources by developing new energies and improvement on the self-sustenance rate remain far from success. Related policies both in Japan and overseas are shifting from the conventional efforts for stable supply and economic growth to the handling of deregulation and environmental problems. Energy stratagem has been studied, not regarding energy technology as a mere economic task and working out how the demand for energy should be with the restricted resources, social economy, and environments, taken into account. Models and scenarios are proposed, for the quantitative analysis and evaluation of the energy stratagem wherein the development of technologies for new energy and energy saving are positioned clearly. Especially, concepts emphasized therein are the technique of power source planning and the development of regenerative energy. 24 refs., 32 figs., 15 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.

    As a part of the WE-NET project, the introduction condition of hydrogen as substituting energy and CO2 reduction effect were analyzed using a global energy model. The WE-NET project aims at global-wide introduction of clean energy by converting abundant renewable clean energy into hydrogen transportable to distant consumers all over the world. The study result in fiscal 1996 is as follows. Undeveloped hydroelectric resources in the world are estimated to be 12 trillion kWh/y equivalent to the existing developed one in the world. Since the cost of the hydroelectric power generation projects over 1000MW in the planning stage is estimated to be 0.02-0.05$/kWh lower than that of other renewable energies, such projects are expected as energy source in the initial stage of the practical WE-NET project. The GREEN model was modified by adding a hydrogen analysis function, and extending an analysis period. The modified model allowed evaluation of the long-term important role of hydrogen energy, in particular, the capability of CO2 gas reduction all over the world. 28 refs., 92 figs., 56 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.

    With relation to some global energy systems of which viability is predicted in the future, an evaluation was conducted from the viewpoints of economical efficiency, energy balance, CO2 emission, etc. The fossil fuel CO2 capture system, the conventional thermal power plant added with CO2 recovery/treatment facilities, is expected to reduce approximately 70-75% of the CO2 emission. The fossil fuel decarbonated hydrogen system, which decarbonates fossil fuels, recovers/treats CO2 at the place of fuel supply and uses as hydrogen, is of poor practical application from an economical point of view. The fossil fuel methanol synthesis system, which synthesizes methanol from fossil fuels at the place of fuel supply, generates electric power and recovers/treats CO2 with the methanol, is large in energy loss and CO2 emission and low in overall efficiency and CO2 reduction effect at the time of methanol synthesis. The renewable energy hydrogen system is an ultimate system with no emission of CO2, though it costs much. 110 refs., 83 figs., 107 tabs.

    Introduction of a number of robots and consumption of a large amount of energy are unavoidable if a complicated process operation is to be carried out by robots in an extensive work site. Great energy conservation is contrived by developing robots applicable to manufacturing in performing a variety of operations in place of human beings and thereby reducing the number of robots to work. This paper explains the fiscal 2000 results. For dual-handed cooperative tasks, a function was examined capable of gripping an object without giving a humanoid robot an instruction of an exact gripping position. A method was designed to prepare a command for the other arm through a command for one arm, with torque impedance control employed for the purpose of avoiding damage due to collision. A study was conducted on a three-dimensional shape detecting model using a visual device of a robot. In grasping problems of balance control of a humanoid robot, the behavior of a robot consisting of multi-links was considered as behavior of inverted pendulum, with possibility checked for the stabilization of the balance. For the purpose of putting the virtual robot platform previously developed to practical use, a three-dimensional operation tool of run-time user interface was developed, with research conducted on the sophistication of robot application.

An energy recovery has been conducted by the recovery of waste heat from the boiler replaced from the water-cooled up-take without increasing temperature in the inlet of boiler, which lead an increase of about 5,000 MWH a year of electric power generation. The fuel mixing combustion and the substitute fuel combustion have been also performed. The fuel was changed from the heavy oil to the pulverized coal, and subsequently, to the coke breeze. The substitution of fuel resulted the decrease of the cost in the electric furnace and the manhour for maintenance as well as the fuel cost. A FSFE operational technology called carbon monoxide concentration control was developed, in which the special qualities of coke could be utilized. Finally, the operational technology without using the electric furnace initially equipped was established. 7 refs., 16 figs., 6 tabs.

    With an objective to contribute to economic growth and global environment preservation in the Asian territories, investigations were made on histories of energy conservation and environment preserving measures used in Japanese iron and steel industry. Energy conservation in blast furnace and converter methods are based on the following actions: improvement in energy efficiency (charging moisture adjusted coals and other techniques), energy recovery (blast furnace gas expander power generation and converter gas recovery), process simplification (continuous casting, heated piece charging and other techniques), and use of alternative energies. With regard to the environment, application of such environmental preserving measures have been advanced rapidly since the 1965`s as waste gas reduction, coke furnace gas liquefaction, and reduction of dusts, soots and noise. At the same time, slag re-utilization has been moved forward. As the building material demand has increased, the use of electric furnace steel making process using scraps has increased, whose production has exceeded one-third of the crude steel production, or 32 million tons. Energy conservation in the electric furnace process consists of use of ultra high power, direct current and scrap preheating, by which unit requirement in calorific power was reduced from 1.5 million to 1.2 million kcal/t or less. The unit requirement for energy consumption for crude steel production in the Japanese iron and steel industry has reduced by 10% from 4.96 million kcal/t in fiscal 1980 to 4.44 million kcal/t in fiscal 1989. 159 refs., 84 figs., 25 tabs.

    In relation to the conceptual design of the total system of hydrogen utilization, the paper described the fiscal 1997 result. The study was conducted having no relation with the conventionally assumed large-scaled/centralized utilization based on the hydrogen produced from renewable energy. Costs of coal gasification and natural gas reforming hydrogen production become lower than that of the hydrogen from the hydroelectric power utilization overseas. However, the processing of CO2 fixation is at a developmental stage, and it is required to see and watch it in the future including the time of the commercialization and economical efficiency. Further, the hydrogen recovered from industrial complexes has a possibility of becoming sources for the distributed utilization (hydrogen diesels, fuel cells, and hydrogen cars). The pipeline transportation of hydrogen gas via the East China Sea from China can be expected. The CO2 emission unit requirement of the power system by liquid hydrogen transportation/ammonia transportation is equal to that of the renewable energy power system and low in environmental loads. The unit requirement of the methanol transportation power generation, in which coal is used, is the same as that of the LNG fueled power generation and inferior in environmental characteristics. The combination with the CO2 fixation processing technology is indispensable. 25 refs., 53 figs., 60 tabs.

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.

    The energy saving environment-friendly technology for low- grade difficult-to-process ores was researched focusing attention on the hydro-metallurgical process of non-ferrous metals. This research aims at development of both effective leaching system of metals, and separation/crystallization system recognizing the property difference between metal ions in solution. The leaching system allows the inexpensive molecular level control of electron transfer, mass transfer of metal ions and stabilization of leached metal ions in a solid/liquid interface. The system thus allows selective leaching of metals from various resources such as difficult- to-leach sulfide minerals to prepare concentrated solutions. The separation system can obtain high-purity solutions including each metal ion by advanced separation/concentration technology from the solutions. The crystallization technology (including electrolysis) is developed for preparing target metal materials by molecular level control of nucleation, particle growth, thin film formation and bulky metal formation processes. Overall energy consumption is reduced to 1/3 of that of the pyro-metallurgical method, aiming at zero emission. 15 refs., 14 figs., 11 tabs.

    The efficiency of a Sol-Air Heat Pump System that is operated throughout the year with as solar energy and air as the heat source is influenced by the weather and the heat exchange characteristics of a direct expansion type sol-air heat collecting panel. In this report, the basic experiment of a SAT meter and panel was conducted. The value measured using the SAT meter was compared with the trial value obtained from the calculative formula of SAT so as to confirm the cooling and heating effects based on radiation (effective radiation and solar radiation). Using the same panel as in an actual system, a basic experiment was conducted to measure the cooling effect based on long wavelength radiation, the heating effect based on solar radiation, or the convection heat exchange. The radiation heat exchange amount at night in summer little varies depending on the time. Using a standard panel, a radiation-cooling amount of about 21% was obtained for the total heat exchange amount. In winter, a solar radiation-heating amount of about 75% was obtained. Many other data items were also obtained. The result showed that it was effective to employ the concept of SAT for a natural energy system. 22 refs., 18 figs., 2 tabs.

    Research and development is actively conducted on machining technologies using plasma in various fields, with studies energetically pursued on etching techniques or those of forming a thin film by the use of high frequency and microwave plasma. The EBEP system jointly developed by Kawasaki Heavy Industries Ltd. and Institute of Physical and Chemical Research is a plasma source for forming a high density plasma by implanting into a plasma chamber from the outside a high-current electron beam accelerated to an energy of approximately 60 to 100eV where the collision cross-section of gas ionization is maximized. The characteristics of the system are such as (1) it enables electron energy distribution to be controlled from outside by varying acceleration voltage, (2) it excels in the controllability of ion energy and (3) it allows to form a steady high-density plasma in a nonmagnetic field. This paper presents the generating principle of EBEP, its plasma characteristics, etching technique using EBEP, thin film forming technique by EBEP-CVD method, and multipurpose apparatus for research and development. 6 refs., 7 figs., 1 tab.

    Regulations, conventions and agreements relating to the discharging liquefied carbon dioxide (CO2) into the bathypelagic zone from a cruising ships are investigated. The ocean storage of CO2 is not specifically prohibited by law, but must be regulated on a global scale because such treatment may impact the marine environment. In principle, treatment with impact on the nature is prohibited. Laws of environmental conservation are completed in European, Asian, and Pacific countries, which join international conventions and committees with high interests. It is suggested that the engineering technique of the storage should be improved to observe regulations and that an impact assessment for the ocean storage should be carefully conducted in full understanding of the basic premise of the regulatory systems or organizations. Furthermore, it is significant to study on the possible effect of the ocean storage of CO2 on global warming and life-cycle assessment inventory analysis, namely the balance of the energy budget between the separation and the ocean storage of CO2. 23 refs., 7 figs., 6 tabs.

    The paper described the results of the development of technology of low temperature materials in the fiscal 1997 WE-NET. Using experimental equipment for materials under the atmosphere of liquid hydrogen, an experiment on mechanical characteristics under the liquid hydrogen atmosphere (20K) was conducted of the base materials of candidate steels (SUS304L, SUS316L and A5083). In material evaluation experiments (tension/fracture toughness/fracture tests), characteristic behaviors of the materials were shown which are different from those shown in the environment of liquid He (4k), etc. Even if the amount of {delta} ferrite in the metal welded of the stainless steel is small, approximately 1%, the degradation of low temperature toughness occurred. Welded joints of stainless steel by submerged arc welding and MAG welding were in now way inferior in tension characteristic to those by TIG welding, but were inferior in toughness ranging from room temperature to extremely low temperature. As to aluminum alloys, materials excellent in extremely-low temperature toughness were able to be found. Under the low temperature hydrogen gas atmosphere, the lower the strain rate is, the higher the hydrogen brittleness susceptibility is around 220K (extremely large hydrogen brittleness temperature) (SUS304L). In the hydrogen gas of 100 atm, hydrogen invades the material at 100degC, but does not at 77k. 38 refs., 173 figs., 48 tabs.

    This report describes the fiscal 1998 result on the magnetic domain-response 3-D optical memory of the nanometer-controlled optical disk system. The magnetic domain response technology is a next-generation optical disk technology which copies fine bits recorded on a recording layer on a read-out layer while magnifying them, and detects the bit smaller than a read out optical spot as large signal level. Magnetic domain-response read out of a fine magnetic domain of 0.12{mu}m in mark length and 0.60{mu}m in track width recorded by optical pulse magnetic field modulation was attempted under the conditions of conventional wavelength (around 680nm) and NA (0.55), and succeeded in expanding unobservable signals up to saturated amplitudes. This is equivalent to a 2-D recording density of 10Gbit/in{sup 2}. Crosstalk-free read out was also verified. As for R and D on the magnetic circular polarization enhanced multiple read out system, the 2-wavelength read out system was fabricated by using 515nm Ar laser light and 780nm semiconductor laser light. It was verified in 2- wavelength read out test that the multi-wavelength read out system is reasonable theoretically. (NEDO)

    As a part of the WE-NET project, the basic technology necessary for large-scale hydrogen liquefaction facilities was studied. The process efficiency over 40% was targeted, and the plant cost was evaluated by complexity of the liquefaction process. Since the recycling line consumes a large amount of gas, the cost and supply method of gas were evaluated. The refrigerant cost for open inspection and leakage refilling was also estimated. Since the stage of centrifugal compressors decreases with an increase in average gas molecular weight followed by increase in compression ratio, the compressor was evaluated by average molecular weight. The expansion turbine was also evaluated by the same way. The heat exchanger was evaluated by volumetric flow balance. Since the liquefaction line uses combustible hydrogen, the safety of the recycling line was evaluated by combustibility of hydrogen. Five liquefaction processes such as hydrogen Claude, helium Brayton, neon Brayton, mixed refrigerant and nelium Brayton cycles were compared. Based on the relative evaluation result, the former two cycles were selected for the future precise study. 14 figs., 19 tabs.

    Energy is the capacity to do the things we are capable of and desire to accomplish. Most often this is thought of in terms of PEP--personal energy potential--a reservoir of individual vivacity and zest for work. Like a battery, energy can be conceived of as a resource that is alternatively used and replenished. Transitions between activities, variety of tasks, and choices of what to spend energy on are part of energy management. Energy capacity can be thought of at four levels: (a) so little that harm is caused and extraordinary steps are needed for recovery, (b) a deficit that slightly impairs performance but will recover naturally, (c) the typical range of functioning, and (d) a surplus that may or may not be useful and requires continual investment to maintain. "Flow" is the experience of optimal energy use when challenges balance capacity as a result of imposing order on our environment. There are other energy resources in addition to personal vim. Effective work design reduces demands on energy. Money, office design, and knowledge are excellent substitutes for personal energy. PMID:22856055

    This review article focuses on the utilization of several catalysts during coal pyrolysis and gasification. In situ or off line catalytic upgrading of volatile matters during pyrolysis of low rank coals is carried out in pressurized H2 with different reactors to produce BTX (benzene, toluene and xylene). When NiSO4 and Ni(OH)2 are used in the hydropyrolysis of Australian brown coal using an entrained bed reactor with two separated reaction zones, BTX yield reaches 18-23%. MS-13X zeolite and USY zeolite mixed with Al2O3 are effective for producing BTX with powder-particle fluidized bed and two-stage reactors, respectively. Catalytic gasification is described from a standpoint of direct production of SNG(CH4) from coal and steam. When K2CO3 and Ni are compared for this purpose, Ni catalyst is more suitable at low temperatures of 500-600degC, where CH4 formation is thermodynamically favorable. Fe and Ca catalysts can successfully be prepared from inexpensive raw materials and are rather active for steam gasification at {>=}700degC. The use of upgrading and gasification catalysts is discussed in terms of preparation, performance, life and recovery. 27 refs., 6 figs., 2 tabs.

    This paper describes the research result on the conceptual design of the total system for the WE-NET project in 1996. Basic conditions are as follows: solid polymer water electrolysis, hydrogen combustion turbine power generation, hydrogen transport/storage through ammonia medium, power generation scale of 1000-4000MW (2-5 yen/kWh), and transport distance of 5000-20000km between supply and consumption places. The system efficiency was estimated to be 68% and 23% at an ammonia arrival time and power sending end, respectively, and it was dependent on a transport distance, while no power generation scale. The power cost was estimated to be 7 yen/Mcal and 33 yen/kWh, respectively. The system efficiency at a sending end was lower by 15% and 2% than that of the liquid hydrogen and methanol system, while the power cost was higher by 0 and 8 yen/kWh, respectively. It was necessary for loss reduction of this ammonia system to develop a new high-efficiency ammonia synthesis process, and hydrogen separation (decomposition/refining) process. 80 figs., 52 tabs.

    The aim is to create inorganic materials with their functions well harmonized and with their reliability remarkably improved, and efforts are made to establish basic technologies with which structural control may be carried out simultaneously for multiple layers in in-process products through positive utilization of various chemical reactions in the materials synthesizing process. This fiscal year's achievements are stated below. A low-temperature pressure nitriding method is developed in which nitriding reaction directly involves the metal aluminum compact for conversion into ceramics, and an aluminum sintered body is produced capable of high thermal conduction of not less than 170w/mk with the original compact shape retained. By a heat treatment in a high-temperature pressure nitriding atmosphere, a success is attained in producing a silicon nitride ceramic body enhanced (150w/mk) in thermal conduction. It is clarified that the microwave-aided selective heating technology works effectively in enhancing the particle growth rate in a liquid-phase sinter system, and a success is won in increasing strength by virtue of the formation of particle-growing particles.

    This paper describes the formation of fluoride layer on the surface of hydriding alloys. The fluoride formation reaction consists of a reduction removal process of surface oxide and a fluorination process. Specific surface area of alloy grains can be increased by the hydrogenation reaction in the surface layer accompanied with the removal of surface oxide, which results in easier permeation of molecular hydrogen into fluoride layer. During the fluorination process, a large amount of Ni in the alloy components is eluted, which results in the reduction of Ni distribution immediately under the fluoride layer in the alloy. Consequently, collector sites near the surface are reduced, and conductivity among alloy grains is degraded. To enhance the hydrogen collector sites, specific surface area of alloy grains can be increased by controlling the pH value of fluorination treatment solution in a given range. Moreover, performance of fluoride layer can be advanced by electrochemically dispersing metal Ni in the fluoride layer using Ni complex ion mixed in the treatment solution. 2 refs., 3 figs.

    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)

    The automatic control system of hoist cranes for automatic guided systems was developed which is composed of separated anti-sway nd position control. This system is equipped with a control equipment, vector control inverter, and induction motor for traversing and traveling. The system detects trolley position, wire length and sway angle, computes velocity commands by the control equipment for exact stop at a target position, and controls velocity by the vector control inverter. The system applies acceleration feedback to anti-sway, and makes it possible to obtain non-vibrational velocity response of loads corresponding to velocity commands for position control. The position control also generates the velocity command harmonizing a stop position and the minimum value of a quadratic curve, to reduce vibration energy generated during acceleration and deceleration. As the experiment result, the anti-sway control could achieve smooth stop with no sway at a target position. 8 refs., 7 figs.

This report covers the recent result of an effort to use very fine alga for CO2 fixation in a NEDO-commissioned joint program participated in by the industry, government institutes, and universities. This is a project that aims to make use of solar energy through the intermediary of the photosynthetic activity of very fine alga for the fixation of the CO2 gas in presence in high concentration in exhaust gas and, at the same time, to extract useful substances out of the alga. More than 3000 kinds have already be collected, screened, isolated, and evaluated for their multiplication performance. A number of superior strains have been selected, including standard strains whose CO2 fixing capacity is higher than the predetermined level, those superb in resisting high temperature or tough in the given environment (flexible with varied culture conditions), and others that are excellent in yielding useful substances such as oil. A 200-liter class bioreactor of the airlift-plate type is now available, and full-scale experiments have been under way since April, 1997. 9 figs., 1 tab.

    For the purpose of reducing the risk of deep geothermal resource development, the paper investigated three factors for the formation of geothermal resource in the deep underground, that is, heat supply from heat source, supply of geothermal fluids, and the developmental status of fracture systems forming reservoir structures. The survey further clarified the status of existence of deep geothermal resource and the whole image of the geothermal system including shallow geothermal energy in order to research/study usability of deep geothermal resource. In the deep geothermal resource survey, drilling/examination were made of a deep geothermal exploration well (`WD-1,` target depth: approximately 3,000-4,000m) in the already developed area, with the aim of making rationalized promotion of the geothermal development. And the status of existence of deep geothermal resource and the whole image of the geothermal system were clarified to investigate/study usability of the geothermal system. In fiscal 1995, `WD-1` in the Kakkonda area reached a depth of 3,729m. By this, surveys were made to grasp the whole image of the shallow-deep geothermal system and to obtain basic data for researching usability of deep geothermal resource. 22 refs., 531 figs., 136 tabs.

    Studies are made of optimum materials and methods for manufacturing low-carbon fuels for reduction in greenhouse gas emissions. When their thermal dynamic limits and the technological maturity are considered, it is inferred that no extensive improvement will be achieved by merely improving on the efficiency of the existing fuels. The use of various high-efficiency driving power sources utterly different in mechanism from the conventional ones, such as those for fuel cell-powered automobiles, and the promotion of the use of low-carbon fuels such as methanol and methane for all kinds of driving power sources including those for the said fuel cell-powered automobiles, will become necessary. The use will also be necessary of recyclable materials. The biomass resources, in particular, since they absorb CO2 gas in their growing process by virtue of photosynthesis, may be said to be free of CO2 gas emissions. They have their own problems, however, which involve the economy of energy consumed for their production, harvesting, transportation, and conversion into fuels. It is therefore required that their whole life cycle be studied before their greenhouse gas reduction effect may be correctly assessed. The quantities of resources available for the production of automotive low-carbon fuels, manufacturing technologies, etc., are first of all put in order for easy perusal. An effective way is assessed for the whole including the life cycle. (NEDO)

    Research and development have been carried out with an objective to re-utilize waste cable covering materials as oil substituting energy. The research has been performed on behavior of chlorine and lead being substances that impede making the cable covering materials into fuel, development of a technology to remove chlorine, lead and copper, and pelletizing properties for fuel making. In the study of behavior of chlorine and lead, the following matters were made clear: dechlorination reaction completes within 30 minutes if pyrolysis temperature is higher than 300 degrees C; the more the amount of filler CaCO3 in test samples, the less the dechlorination amount; and secular deterioration does not affect the dechlorination amount. A technology has been developed successfully to remove the substances that hinder making the cover materials into fuel, achieving the target values of copper at 0.2% or less, lead at 0.3% or less, and chlorine at 5% or less. In developing the pelletizing technology that puts the cover materials into raw materials for blast furnaces, dechlorination rate of 90% was achieved by mixing coke/PVC at a ratio of 1/1 and dechlorinating it by using a rotary kiln. It was verified that the product is free of problems in particle size as the blast furnace raw material. (NEDO)

    In the fiscal 1995 study, items were searched which are keys to the design of a liquid hydrogen tanker of a capacity of 200,000m{sup 3}. Among those, the basic concepts were summarized which are necessary for the design of a liquid hydrogen tanker in terms of safety, and the extraporation of the existing low temperature technology into the large liquid hydrogen tank was studied. When adopting safety conditions of IGC Code applied to LNG to the liquid hydrogen tanker, it is necessary to limit the discharge amount of hydrogen to 3 kg/s. When considering safety at fire, for keeping safety of the same level as that of the LNG tanker, it is not appropriate to adopt the conventional vacuum insulation liquid hydrogen tank. In the fiscal 1995 study, 7 kinds of concept of the insulation structure were assumed, and it was concluded that BOR of 0.04-0.23/d was obtained. Also in fiscal 1996, the large liquid hydrogen tank was studied. For insulation of the large liquid hydrogen tank, the structure is most promising where AEROSIL bag or homogeneous AEROSIL is substituted for a forming heat insulating material of 4 design, but further study is needed for selection of the optimum heat insulating structure. 9 figs., 6 tabs.

    For this survey, the latest technology trends relating to microbial functions are summarized to recover and effectively utilize CO2, typical greenhouse effect gas, using microbial functions. Systematic survey and analysis are conducted concerning the microorganisms useful for fixing CO2, CO2 uptake mechanism during the microbial reactions, utilization methods of solar light and useful energy sources except solar light, highly efficient production of useful materials, and usage of produced useful materials. Research has concentrated on use of biological activities for this purpose through design of bioreactors using microorganisms (bacteria and microalgae) for efficient CO2 fixation. For the process to have net CO2 fixation as assessed by its life cycle and to make the process economically feasible, it is essential not only to fix CO2 merely in the form of biomass but in addition to convert it to useful materials by the catalytic activities of the organisms. Three categories were set for the survey, i.e., microorganisms with CO2 fixation ability, available energy for CO2 fixation, and target CO2 fixation products. 169 refs., 49 figs., 14 tabs.

    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.

    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)

    Receiving subsidies from MITI, NEDO carried out this project in fiscal 1995 and 1996 as a joint research with Technology Research Association for Phosphoric Acid Fuel Cell Power Generation System and others. The project aimed at developing the accelerated test method which can evaluate in a short time the cell life of phosphoric acid fuel cells (PAFC) and the lowering of characteristics. The accelerated test method of PAFC life is thought to be a tool indispensable for the promotion of commercialization, but the accelerated test method like the usual material evaluation has not yet been established. To solve this problem, procedures were developed to rationally plan the accelerated test on short stacks of full scale based on the small cell test data. Here, to rationally estimate the operational state under actual conditions based on the data on the accelerated test, it is necessary to fully understand the mechanism of deterioration of PAFC. By conducting in parallel the element study for the basic elucidation of cell deterioration phenomena, obtained was the useful information/knowledge which back up the results of the accelerated test scientifically. 168 figs., 33 tabs.

    This paper describes the achievement in fiscal 1997 of analyzing practical application of a technology to manufacture solar cell silicon raw materials. Silicon consumption for solar cells in fiscal 1997 has increased to 2000-ton level, and the supply has been very tight. For drastic improvement in the demand and supply situation, development of SOG-Si manufacturing technology and its early practical application are desired. The development of the NEDO mass-production technology using melting and refining has completed constructing the process facilities in fiscal 1998, and will enter the stage of operational research. However, insufficiency in the basic data about behavior of impurities is inhibiting the development. In the substrate manufacturing technology, discussions have shown progress on use of diversifying silicons outside the standard by using the electromagnetic casting process. For slicing and processing the substrates, development of a high-performance slicing equipment and automatic rough rinsing machine is under way. Properties required on silicon raw materials vary considerably widely because of difference in cell making systems and conditions, which is attributable to unknown impurity behavior. When 1GW production is assumed, the cell module manufacturing cost is calculated as 137 yen/W, for which low-cost mass production for its realization, slicing productivity enhancement, and cost reduction are required. The paper also describes site surveys in overseas countries. (NEDO)

    Summarized herein are the materials designs/production and tests/evaluation results of heat-resistant materials, i.e., alloys, ceramic composites and carbon-based composites, which are expected to be applicable to the hydrogen combustion turbines. These have been studied since 1993, and this paper summarizes the overall evaluation results of the phase I program. The intermetallic compound as one of the candidate materials has a high-temperature strength in a range from 1200 to 1400 degrees C by optimizing elements added. However, no prospect is obtained for heat resistance at 1700 degrees C or more for the material not coated or cooled moderately. Each of the other candidate materials tested shows a bright prospect of applicability at the base material and specimen levels. The single-crystal superalloy for hybrid cooling structures has novelty in that it is free of Cr but incorporated with Si and Hf, showing approximately 10 degrees C higher heat-resistant temperature than CMSX-4. CMC and C/C are inherently excellent heat-resistant materials, and are attractive advanced composites, because they are expected to realize no-cooled blades at 1700 degrees C. (NEDO)

    Surveys and studies were conducted for the development of technologies basic to the construction of an ultrahigh-speed huge-capacity high-frequency radio access and communication network, especially the network infrastructure, in the several 10 to several 100 GHz band. Some surveys covered the positioning of high-frequency high-output device modules as the key component, needs for their use in radio communication equipment, devices to be needed for their construction, technologies for their manufacture, process technologies for their embodiment, basic technologies for their materials, and so forth. Some others covered research on the marketability of high-frequency devices in the future, development of relevant technologies abroad, and so forth. The mainstream of high-frequency devices these days rests on the secondary electron gas system based on GaAs and InP, and therefore it is intrinsically difficult for them to yield high outputs. It is deemed to be important to develop technologies based on novel semiconductor materials, such as nitride semiconductors which have excellent properties as materials, toward the construction of a network infrastructure for the next generation.

    Research has been performed with an objective to develop a new circuit configuration that separates data read-out function from memory storage function. This paper summarizes the achievements in fiscal 1999. In developing a circuit simulation technology, the existing macro model was used to derive circuit response in a partially polarized condition. Comparing the hysteresis shape with an experiment revealed that the partially polarized condition can be expressed well. Incorporation into SPICE will be discussed in the future. In the research of optimizing the circuit configuration, an SrTa{sub 2}O{sub 6}/SiON buffer layer was used to have fabricated a ferroelectric gate FET being the constituting element of the memory cell. The function separation type 1T2C memory was discussed on aggregation, manufacturing processes, and optimal cell arrangement, and was concluded as a superior memory. It was disclosed that the high performance ferroelectric gate FET needs to take the FEMIS structure, and make the area of a ferroelectric capacitor smaller than the area of a buffer layer capacitor.

    In order to realize the next generation ferroelectric memory, research and development has been performed on improvement of quality of ferroelectric thin films and other elements, and optimization of the circuitry. This paper reports the achievements in fiscal 2000. In developing the circuit simulation technology, a macroscopic model was first incorporated into the SPICE, and the capacitor parameters were extracted to verify the behaviors thereof. With regard to the microscopic model, a property based version model and a circuit based version model were prepared and incorporated into the SPICE to verify the reasonability of the models. In the research and development of the circuitry optimization, function-separated IT2C cell was formed by using an SBT film as a ferroelectric substance, and Pt as an intermediate electrode, and SiO{sub 2} as a buffer layer. This cell was identified capable of making non-destructive read-out action, and to have the basic features of the FET type memory having good data retention performance.

    This report describes effectiveness of a system for measuring the acceleration and force in high accuracy by combining a laser interference meter and a vibration stand. A possibility of pressure sensitive paper to the impact force measurement in the collision examination is also described. The results obtained in FY 1997 are as follows. 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.

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    As for road traffic noise, besides the measures of road structure, traffic flow and so forth, making severe noise regulation along with the noise reduction measures of a vehicle simple were carried out many times in the past. However, there is still bad situation regarding the fulfilling the environmental standard due to the increasing traffic volume. Regarding the vibration and noise of the engine, many researches using analysis technique with high frequency resolution are carried out for prediction technology or transient phenomena that are related to optimization. As for riding comfort, research of active/semiactive control is popular from the beginning. There is applicable research of active control with a purpose of achieving riding comfort and fatigue reduction of big truck drivers. As for vehicle body, there are many studies and optimization of experimental technique of related problems of structure and sound generating part. Subjective sound property is an important point for vehicle industry. As for evaluation of sound, most of them rely on the human judgement from the very past. 100 refs.

    Introduced in this report are typical sensors used in robotized welding, which are the arc sensor, contact sensor, and optical sensor. The arc sensor enables welding by utilizing the physical features of arc for the real-time detection of the weld line. Changes in welding current or voltage produced by changes in the distance between the tip and parent metal are the information usually inputted into the arc sensor. This sensor needs weaving for weld line detection. Weaving directly relates to response and tracking characteristics, and is carried out by the robot, high-speed rotary sensor, etc. The contact sensor identifies the weld start point in the absence of welding current and a touch sensor is often used capable of switching the welding power source to the contact probe circuit for the torch itself to serve as a probe. The optical sensor detects a laser beam with the aid of CCD for the measurement of the position, groove shape, and dimensions. For improving accuracy and other properties, algorithm based on the modern control theory has begun to be incorporated into the sensors for use in robotized welding. 15 refs., 12 figs., 1 tab.

    Somatic cell cloning technologies are explained, and their use in the manufacture of biologically active substances such as pharmaceuticals is described. In general a cloning technology means a technology of nucleus transfer in which the nucleus of an ovum is removed and the nucleus of another cell is transferred. Since a mammalian ovum is but 100-150{mu}m in diameter, the removal or transfer of a nucleus has to be performed under an inverted microscope provided with a micromanipulator. In 1986, this method was employed for the transfer of a cell nucleus at its early division stage in a sheep embryo, and a sheep was cloned. The production of useful substances such as pharmaceuticals is performed through gene recombination for coli bacteria, yeast fungi, and cultured mammalian cells, but there are some problems to be solved about the amount produced, cost of production, biological activity, etc. Under such circumstances, a concept of animal factory has been invented in which Tg (transgenic) animals themselves are utilized as bioreactors, and several venture organizations have already been incorporated. 3 refs., 1 fig., 1 tab.

    Sludge generating in a sewage treatment plant is disposed through the processes such as concentration, dehydration, and incineration in sludge disposal facilities. In recent years, there has been a trend that this sludge increases in volume as well as worsens in the concentration. A case is predictable where the sludge load to the dehydrating process is so large that the sludge can no longer be processed in sufficient quantity. In the meantime, if sludge is ozone-treated, viscous substance on the surface of sludge particles can be separated with a comparatively small amount of ozone, with sludge concentration enhanced. At Meidensha, an experimental plant was set up for the ozone treatment of sludge in a sludge intensive treatment plant of a metropolis, with a verification experiment carried out for a sludge concentration improving system by ozone. As a result of comparison of the treatment performance between an assessment system for performing ozone treatment and a reference system for not performing, the average value of the sludge concentration of a gravity concentration tank was 1.9% of the reference system against 1.7% of the assessment system in a continuous treatment experiment in the summer, while the solid collection ratio was 65.8% of the reference system against 95.5% of the assessment system, enabling a superior improving effect to be obtained.

The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

    This paper describes technologies for LTA (lighter-than-air aircraft). LTA such as airship and balloon cruises by static buoyancy of gas. Since the body of LTA becomes large inevitably because of small buoyancy of gas, LTA has such essential demerits as dependence on wind, inconvenient handling and low speed. However, LTA is featured by large carrying capacity by large body, and long-distance and long- time flight. At present, LTA is in use for not military use and transport but advertisement, publicity, sports and observation. For development of its new fields, a stratospheric platform for a radio relay station and ground monitoring is in experiment which is composed of many unmanned balloons around 20km in altitude. A solar airship with solar panels on its wide surface is also under investigation. A planet observation balloon is also under review in many countries. The pioneering of the upper part (30-40km in altitude) of the stratosphere by LTA is promising because such space is a frontier never pioneered by manned light plane. (NEDO)

    The present and future of neural network technologies were reviewed. Neural networks simulate the neurons and synapses of human brain, thus permitting the utilization of heuristic knowledge difficult to describe in a logical manner. Such networks can therefore solve optimization problems, difficult to solve by conventional computers, more rapidly while sacrificing a permissible degree of rigor. In light of these advantages, many attempts have been made to apply neural networks to a variety of engineering fields including character recognition, phonetic recognition diagnosis, operation and so on. Now that these attempts have demonstrated the great potential of neural network technology, its application to practical problems will receive increasing attention. The necessity for fundamental studies on learning algorithms, modularization techniques, hardware technologies and so on will grow in conjunction with the above trends in application. 20 refs., 11 figs., 1 tab.

    Designing a vessel to sail oceans for an extended period of time requires statistical estimation on different hull responses to waves. To meet the requirement, it is necessary to accurately identify hydrographic conditions (particularly waves) which are considered to be encountered by the vessel. This paper makes clear the statistical characteristics of the wave statistics table presented by Fang et al, and compares them with other processes for discussion. This statistics collection is based on data collected in China, Hong Kong and Japan, including those collected in the Sea of Japan, the Yellow Sea, the North Sea, the East China Sea and the South China Sea. It was found that these data provide results slightly lower than the long-term estimation values derived from data of the global wave statistics (GWS) prepared by Hogben et al. The cause for this was found attributable to the format of the statistical data, especially setting of wave height classes. However, since the data provided by Fang et al include items of detailed information on small sea areas near the Chinese coast lines, the data are thought to provide useful information source in investigating long-term hull response characteristics relative to spatial spread of the sea areas in the North-west Pacific Ocean. 15 refs., 5 figs., 2 tabs.

    Increased focus has been placed on the issues of energy access and energy poverty over the last number of years, most notably indicated by the United Nations (UN) declaring 2012 as the 'International Year of Sustainable Energy for All'. Although attention in these topics has increased, incorrect assumptions and misunderstandings still arise in both the literature and dialogues. Access to energy does not only include electricity, does not only include cook stoves, but must include access to all types of energy that form the overall energy system. This paper chooses to examine this energy system using a typology that breaks it into 3 primary energy subsystems: heat energy, electricity and transportation. Describing the global energy system using these three subsystems provides a way to articulate the differences and similarities for each system's required investments needs by the private and public sectors.

  2. Nuclear energy and energy security

    International Nuclear Information System (INIS)

    Do Georgia needs nuclear energy? Nuclear energy is high technology and application of such technology needs definite level of industry, science and society development. Nuclear energy is not only source of electricity production - application of nuclear energy increases year-by-year for medical, science and industrial use. As an energy source Georgia has priority to extend hydro-power capacity by reasonable use of all available water resources. In parallel regime the application of energy efficiency and energy conservation measures should be considered but currently this is not prioritized by Government. Meanwhile this should be taken into consideration that attempts to reduce energy consumption by increasing energy efficiency would simply raise demand for energy in the economy as a whole. The Nuclear energy application needs routine calculation and investigation. For this reason Government Commission is already established. But it seems in advance that regional nuclear power plant for South-Caucasus region would be much more attractive for future

  3. Energy efficiency through energy audit

    International Nuclear Information System (INIS)

    Energy is an essential factor to economic and social development and improved standards of living in developing countries. Nigeria in particular. There is a strong need for greater energy efficiency in every sector of economy in order to reduce costs. enhance competitiveness, conserve energy resources and reduce environmental impacts associated with production, distribution and use of energy. Energy auditing and monitoring has a significant role in any energy management and conservation project. Energy auditing as an important part of industrial energy management on plant level, represents a complex of activities aiming at the efficient use of energy. The activities are undertaken by a team of experts who use a set of measuring instruments to monitor and evaluate all the necessary data to elaborate a package of recommendations on improvements in the field of energy efficiency and possible product quality. The inefficient conversion and use of energy have been identified as a central problem for all developing countries, Nigeria inclusive, since they all consume significantly higher amounts of energy per unit of GDP than OECD countries. This aggravates energy-related environmental problems and is also a burden on domestic resources and foreign exchange. Energy prices have risen drastically in many developing countries, while energy intensities remain high. Price changes alone are not rapidly translating energy efficiency improvements. Identifying and removing the obstacles to greater energy efficiency should be priority for government in developing countries. This is why the Energy Commission, an apex organ of government on Energy matters in all its ramifications is out to encourage relatively low-cost energy audits for the Textile industries - such audits can identify ''good house-keeping's' measures, such as simply process improvements, that reduce energy consumption and operating costs. This will be followed by the training of plant workers/energy managers

    This survey clarifies the present situation of the solar heat utilization technology mostly for industrial use, makes a concrete concept of solar heat utilization clear, and extracts items of the technology development and evaluates sociality, economical efficiency, etc. It aims at working out a program for the future technology development. The following proposals were made: 1) technology development program; 2) simulation soft development program; 3) experimental field of the solar heat utilization technology. In 1), concepts of technology development are 'medical use boiling pasteurization,' 'temperature increase in the metal surface treatment process,' 'water purification using photo-catalyst,' 'distributed small power system,' and 'waste water treatment using bio-technology.' In 2), cost reduction is needed for commercialization/merchandising of technology, and therefore, the development of simulation software is studied. In 3), as the experimental field from commercial/residential use system to industrial use system, an large-scale and systematical experimental field is proposed where all that can be substituted for by solar energy among the energies required for the urban function are used. By this, the solar heat utilization system gets accustomed to the people, increases the reliability, and clearly leads to the course to the next stage of the R and D. (NEDO)

    Capacity increase and efficiency improvement have become possible as a result of increasing the voltage and capacity in power semiconductors. On the other hand, the amount of harmonic current generated is increasing. Discussions have been given on the harmonics suppression technologies in order to suppress damages given by voltage distortion in the power system to devices connected in the same system. Among the representative harmonics suppression measures for large-capacity devices, the measure applied to the device side is pulse multiplication and use of PWM in power converters as the source of harmonics generation. Systems that absorb harmonics generated from converters by filters use active filters and passive filters (L-C filters). A separately excited three-phase bridge circuit suppresses the harmonics by offsetting harmonic currents with each other by using a multiplied pulse system with shifted phase angles. A cycloconverter uses, together with the pulse multiplication, an active filter to absorb low-order harmonics. A large-capacity self-excited converter uses a multiplex transformer system to increase the number of synthesized pulse and suppresses harmonics by using the multiplied pulse PWM system. 7 refs., 5 figs.

  16. Energy systems

    International Nuclear Information System (INIS)

    Up to the present the production, transmission and distribution of energy has been considered mostly as a fragmented problem; at best only subsystems have been considered. Today the scale of energy utilization is increasing rapidly, and correspondingly, the reliance of societies on energy. Such strong quantitative increases influence the qualitative nature of energy utilization in most of its aspects. Resources, reserves, reliability and environment are among the key words that may characterize the change in the nature of the energy utilization problem. Energy can no longer be considered an isolated technical and economical problem, rather it is embedded in the ecosphere and the society-technology complex. Restraints and boundary conditions have to be taken into account with the same degree of attention as in traditional technical problems, for example a steam turbine. This results in a strong degree of interweaving. Further, the purpose of providing energy becomes more visible, that is, to make survival possible in a civilized and highly populated world on a finite globe. Because of such interweaving and finiteness it is felt that energy should be considered as a system and therefore the term 'energy systems' is used. The production of energy is only one component of such a system; the handling of energy and the embedding of energy into the global and social complex in terms of ecology, economy, risks and resources are of similar importance. he systems approach to the energy problem needs more explanation. This paper is meant to give an outline of the underlying problems and it is hoped that by so doing the wide range of sometimes confusing voices about energy can be better understood. Such confusion starts already with the term 'energy crisis'. Is there an energy crisis or not? Much future work is required to tackle the problems of energy systems. This paper can only marginally help in that respect. But it is hoped that it will help understand the scope of the

    International Nuclear Information System (INIS)

    In the case of Cuba, energy security goes beyond the typical security framework of energy supply to encompass the economic blockade which affects Cuba's access to some markets for its traditional products and obstructs international credit options. Recent problems concerning security of national energy supply include: - Shortages of foreign exchange necessary for the purchase of fuel and spare parts, for new investments and for the implementation of programmes supporting the rational use of energy. - High dependence on imported energy, including oil and petroleum products. -Use of domestic crude oil, with energy performance slightly below that of the imported fuels it replaces, especially fuel oil. The main negative aspect is the high sulphur content, which has adverse operational and environmental effects. - Interruptions in energy services resulting from hurricanes and tropical storms, and from breakdowns and accidents related to the transport of fuels, especially coastal transport. The strategies employed to improve Cuba's energy security situation are based on: - Increased economic competitiveness; - Fuel conservation and rational use of energy; - Efficient exploration and use of oil and natural gas; - Development of renewable energy sources; - Legal and institutional support of activities in the energy sector; - Active involvement in the international arena focused on regional integration efforts and international forums related to technological, energy and environmental issues, and on strengthening bilateral alliances aimed at creating the necessary environment for trade, technological transfer and foreign investment for guaranteeing national energy supply

  20. Energy consumption and energy prices

    International Nuclear Information System (INIS)

    Data are presented on energy consumption and energy prices related to a number of OECD (Organisation for Economic Co-operation and Development) lands covering the period 1951-1990. The information sources are described and the development of energy consumption and prices in Denmark are illustrated in relation to these other countries. The energy intensity (the relation between energy consumption and the gross national product) is dealt with. Here it is possible to follow development during the whole post-war period. It is generally understood that Denmark saved large amounts of energy after 1973-74 but, taken over the whole post-war period, savings and decline in energy-gross national product relations are less dramatic compared to conditions in other OECD countries. Energy coefficients or elasticities show the relative rise in consumption compared to the relative rise in gross national product (growth rate). This is shown to be typically unstable and an eventual connection with the amount of energy price increase and/or the growth rate of the national economy is considered. Results of Granger causuality tests on energy consumption, national income and energy prices are presented. Effective energy prices were very low in Denmark up to 1970 when they suddenly began to increase. Since the oil crisis Denmark's energy consumption has fallen whereas the other countries have used rather more energy than before. Effective promotion of energy savings must be seen in relation to the fact that the 1970 basis level of energy consumption and intensity was unusually high. The high effective energy prices have also encouraged energy savings in Denmark. (AB)

    Development is intended to be made on fundamental combustion control technologies applicable to high-performance industrial furnaces that can reduce energy consumption and respond to environment preservation requirements. With an intention to achieve reduction in combustion exhaust gases such as carbon dioxide and nitrogen oxides, fundamental studies will be made on factors to decide flame shapes as represented by high-temperature combustion and flame shape control by utilizing microgravity environment, and researches will be made on combustion systems. Devices required for the experiments were fabricated to evaluate critical combustion characteristics of flames in furnaces including industrial furnaces, analyze and evaluate flame control parameters, and study low-pollution combustion technologies. Experimental methods acquired by 1997 were used for the experiments under the microgravity environment. Evaluation experiments were performed on flame shape control technologies and flame radiation characteristics, and basic experiments on the low-pollution combustion technologies. With these experiments, elucidation of the combustion mechanisms was launched by analyzing and evaluating the acquired data. A flame experimenting device for high-temperature preheated air completed by fiscal 1997 was used to acquire such combustion characteristics data as NOx discharge characteristics when the high-temperature preheated air is used. Based on the result thereof, verification was carried out on simulation models. (NEDO)

    In the research cooperation promotion projects having been carried out, the R and D of an overall recovery system have been conducted which recovers effectively and systematically valuable resources such as magnesium, bromine and boron including in brine made after the salt manufacturing in the coastal region in Mexico. In this project, as the research on the distilling process needed for commercialization of the system to recover valuable resources from the brine, Japan has been collecting information on various distilling processes and solar pond systems and studying a distilling process appropriate to the site jointly with Mexico. As a result, a seawater desalination process which combined the solar pond using solar energy and the evaporation method was recommended as a low-priced distilling method. Moreover, it was indicated that the solar still method for condensing/recovering the evaporated water of the Guerrero Negro salt pan is also less influential in the salt manufacturing process and is viable as a most economical distilling process by studying the structural design and operational method of more efficient solar stills

    Due to sharp rise in oil proces after the 1973 Arab-Israeli War, world attention has been focussed on the energy problem. At present the energy problem is limited to the cost and reliability of supply, even though there are enough supplies to go round. However, in the future the problem will be of availability, because in spite of the full exploitation of currently available conventional energy sources, the supply will fall short of demand which will always be increasing. Hence, there is need to develop alternate energy sources, including fast breeder reactors, fusion reactors and MHD. Economic and technical aspects of these energy are discussed. (M.G.B.)

    International Nuclear Information System (INIS)

    The author is trying very hard to present a systematic and compact description of the energy law as a whole. For reasons metioned in the first chapter, the energy law confines itself to the law relating to energy supplied by means of pipelines and transmission lines. Energy law and the law relating supplied by means of pipelines are therefore synonyms. There is no special energy law except the one relating to energy supplied by means of pipelines. The book - intended to be read by experts and undergraduates - discusses the subject and systematics of energy law, energy control, price regulations for electricity supply industry and for the gas supply industry, the law relating to pipe-laying, licence fees and law on cartels, supply obligations of the electricity supply utilities, legal issues of energy supply contracts, liability for supply disruptions, the legal nature of public energy supply, planning law, the relating to plant licensing, atomic law, legal protection in plant licensing procedures, the current structure of industry supplying energy by means of pipelines and, finally, reform demands.

    This Transportation Energy Project is comprised of four unique tasks which work within the railroad industry to provide solutions in various areas of energy conservation. These tasks addressed: energy reducing yard related decision issues; alternate fuels; energy education, and energy storage for railroad applications. The NIU Engineering and Technology research team examined these areas and provided current solutions which can be used to both provide important reduction in energy usage and system efficiency in the given industry. This project also sought a mode in which rural and long-distance education could be provided. The information developed in each of the project tasks can be applied to all of the rail companies to assist in developing efficiencies.

  2. Energy needs

    International Nuclear Information System (INIS)

    There seems to be a trend towards expecting energy conservation to be a panacea for the world's ills. In fact, a global perspective on energy needs shows that more, not less, energy is needed and technological innovation in energy sources is essential in order to meet the needs of more than just the developed countries. Energy-intensive technology is the amplification of our natural resources rather than their depletion. A fundamental bioethical principle must be established if we are to analyze and organize scientific evidence about hazards from currently feasible energy resources, and separate genuine from counterfeit claims to credibility. In particular, public fears about radiation hazards and radioactive waste disposal are influenced too much by rhetorical cleverness and forensic skills of a vociferous minority. Potential hazard management is ethically equitable only if it is proportioned to actual basic harm that can be identified and reduced by expenditures of human effort, time and money

    From its rebirth in the early 1980s, the rate of development of wind energy has been dramatic. Today, other than hydropower, it is the most important of the renewable sources of power. The UK Government and the EU Commission have adopted targets for renewable energy generation of 10 and 12% of consumption, respectively. Much of this, by necessity, must be met by wind energy. The US Department of Energy has set a goal of 6% of electricity supply from wind energy by 2020. For this potential to be fully realized, several aspects, related to public acceptance, and technical issues, related to the expected increase in penetration on the electricity network and the current drive towards larger wind turbines, need to be resolved. Nevertheless, these challenges will be met and wind energy will, very likely, become increasingly important over the next two decades. An overview of the technology is presented. PMID:17272245

    Wind energy is a variable and uncertain renewable resource that has long been used to produce mechanical work, and has developed into a large producer of global electricity needs. As renewable sources of energy and feedstocks become more important globally to produce sustainable products, many different processes have started adopting wind power as an energy source. Many times this is through a conversion to hydrogen through electrolysis that allows for a more continuous process input. Other important pathways include methanol and ammonia. As the demand for sustainable products and production pathways increases, and wind power capital costs decrease, the role of wind power in chemical and energy production seems poised to increase significantly.

  9. Energy economics

    International Nuclear Information System (INIS)

    The energy demand is strongly conditioned by the consuming equipments. Depending on the uses, some energy sources can be substituted, while for some others the choice is limited or impossible. The energy offer comes mainly from non-renewable resources, and taking into consideration the geographical localization of these resources, economics are geopolitics are indissociable despite the development of markets. Necessary for the economic development, energy cannot be consumed without impact on the environment, which raises some worrying questions, like the one of global warming. (J.S.)

    Geothermal energy has shown a revival for several years and should strongly develop in a near future. Its potentiality is virtually unexhaustible. Its uses are multiple and various: individual and collective space heating, heat networks, power generation, heat storage, heat exchanges etc.. Re-launched by the demand of renewable energy sources, geothermal energy has become credible thanks to the scientific works published recently which have demonstrated its economical and technical relevance. Its image to the public is changing as well. However, lot of work remains to do to make geothermal energy a real industry in France. Several brakes have to be removed rapidly which concern the noise pollution of geothermal facilities, the risk of bad results of drillings, the electricity costs etc. This dossier gives an overview of today's main research paths in the domain of geothermal energy: 1 - geothermal energy in France: historical development, surface and deep resources, ambitions of the French national energy plan (pluri-annual investment plan for heat generation, incentives, regional 'climate-air-energy' schemes), specific regulations; 2 - geothermal energy at the city scale - sedimentary basins: Ile-de-France 40 years of Dogger reservoir exploitation, potentialities of clastic reservoirs - the Chaunoy sandstones example; 3 - geothermal power generation: conventional reservoirs - the Bouillante model (Guadeloupe, French Indies); the Soultz-sous-Forets pilot plant (Bas-Rhin, France); the supercritical reservoirs - the Krafla geothermal area (Iceland).

    Energy measurement has become an important aspect of our daily lives since we have learned that energy consumption, is one of the main source of global warming. Measuring instruments varies from a simple watt-meter to more sophisticated microprocessor control devices. The negative effects...... that fossil fuels induce on our environment has forced us to research renewable energy such as sunlight, wind etc. This new environmental awareness has also helped us to realize the importance of monitoring and controlling our energy use. The main purpose in this research is to introduce a more sophisticated...... but affordable way to monitor energy consumption of individuals or groups of home appliances. By knowing their consumption the utilization can be regulated for more efficient use. A prototype system has been constructed to demonstrate our idea....

  3. Ocean energies

    International Nuclear Information System (INIS)

    This timely volume provides a comprehensive review of current technology for all ocean energies. It opens with an analysis of ocean thermal energy conversion (OTEC), with and without the use of an intermediate fluid. The historical and economic background is reviewed, and the geographical areas in which this energy could be utilized are pinpointed. The production of hydrogen as a side product, and environmental consequences of OTEC plants are considered. The competitiveness of OTEC with conventional sources of energy is analysed. Optimisation, current research and development potential are also examined. Separate chapters provide a detailed examination of other ocean energy sources. The possible harnessing of solar ponds, ocean currents, and power derived from salinity differences is considered. There is a fascinating study of marine winds, and the question of using the ocean tides as a source of energy is examined, focussing on a number of tidal power plant projects, including data gathered from China, Australia, Great Britain, Korea and the USSR. Wave energy extraction has excited recent interest and activity, with a number of experimental pilot plants being built in northern Europe. This topic is discussed at length in view of its greater chance of implementation. Finally, geothermal and biomass energy are considered, and an assessment of their future is given. The authors also distinguished between energy schemes which might be valuable in less-industrialized regions of the world, but uneconomical in the developed countries. A large number of illustrations support the text. This book will be of particular interest to energy economists, engineers, geologists and oceanographers, and to environmentalists and environmental engineers

  4. Energy release

    International Nuclear Information System (INIS)

    Full text: Small island developing states (SIDS) are particularly vulnerable to the vagaries of the world's energy markets. Most depend almost entirely on oil for their needs, but few have any oil of their own. So they must rely on importing it and are enormously exposed to the volatility of its price, and to the uncertainty of supplies. As most SIDS are remote, the fuel has to be transported for long distances, greatly increasing its cost. This dependence entails a major threat to their economies. Importing the fuel absorbs a large proportion of their foreign exchange earnings, constraining investment in economic and social development. Additionally, the high price of energy slows down development even further, and makes it hard for the poor to get energy for the lighting and services they need. Yet, while most SIDS are poor in fossil fuels, they are usually rich in renewable sources of energy such as the sun and the wind and could do much to improve their energy efficiency. They are therefore well placed to benefit from sustainable energy policies, which would cut back their expensive fuel imports and make modern forms of energy much more widely available to their people. There is also a moral reason for taking this approach. Many SIDS are among the countries most vulnerable to the sea-level rise and extremes of climate brought about by climate change - yet they emit only a tiny proportion of the greenhouse gases that cause global warming. Setting an example by cutting back their use of fossil fuels would strengthen their moral position even further. So far, however, little renewable energy is exploited in SIDS, and what development has taken place has been largely restricted to international assistance programmes. Now a planned project, initially in three West Indian islands, partially funded by the United Nations Foundation, aims to speed this up. The Global Sustainable Energy Islands Initiative (GSEII) seeks to bring sustainable energy projects, models and

    International Nuclear Information System (INIS)

    Within the framework of assessing the state of the environment in Lebanon, this chapter describes primary energy demand, the electricity generating sector and environmental impacts arising from the energy sector.Apart from hydropower and traditional energy sources, which together represent 1.7% of energy consumption, all energy in Lebanon derives from imported petroleum products and some coal.Tables present the imports of different petroleum products (Gasoil, Kerosene, fuel oil, coal etc...), their use, the energy balance and demand.Energy pricing and pricing policies, formal and informal electricity generations in Lebanon are described emphasized by tables. The main environmental impacts are briefly summarized. Thermal power stations give rise to emissions of Sulphur dioxide (SO2), particulates, oxides of nitrogen (NOx) and CO/CO2 from combustion of primary fuel informally generated power from both industry and domestic consumption produce particulate materials and emissions of NOx and SO2 projected emissions of SO2 from the power sector with the present generating capacity and with the new combined cycle power plants in operation are shown. Other environmental impacts are described. Recommendations for supply and environment policy are presented

  6. Energy perspectives

    International Nuclear Information System (INIS)

    In France and in Europe, the political vision of energy production has not yet been taken to heart as much as its importance merits, despite a certain awareness of the gravity of the phenomena within the population. It would already be very difficult to halve the consumption of fossil fuels in France in 2050, without a swift and profound change in our energy-consumption choices (in particular in transport) and a considerable research effort. To divide it by four seems unrealistic, since France, unlike other countries, has already benefited from the transition from electricity produced from fossil fuels to nuclear electricity which does not emit CO2. A major evolution in energy, in Europe and throughout the World, is inevitable in the course of the century. To prevent this from being too violent and painful, a process of fundamental research and technological development should be launched forthwith, in all fields of energy production, storage and use, with a large effort supported by major research programmes. Some recommendations are given for the main research fields that should be: capture and long term storage of CO2, energy savings in transport, energy supply to large cities and nuclear power plant enhancement, hydrogen storage, wind energy and its unavailability problem, use of forest resources, photovoltaic electricity in rural and isolated regions, temporary storage of electricity

  13. Energy coppice

    International Nuclear Information System (INIS)

    One form of renewable energy production involves the growing of energy coppice on agricultural land. It is important as it can be grown on those areas of agricultural land which are surplus to agricultural production. Hence it can be seen as an alternative farm crop, and as such, a possible solution to the problem of agricultural surpluses as well as providing a source of energy. Studies have indicated that up to one million hectares of land surplus to agricultural production may be suitable for growing energy coppice. However, its development as an agricultural crop will only happen if it can be produced at costs competitive with alternative fuels and there is a reliable and long term market offering good returns.

  16. Energy efficiency

    International Nuclear Information System (INIS)

    World energy demand is constantly rising. This is a legitimate trend, insofar as access to energy enables enhanced quality of life and sanitation levels for populations. On the other hand, such increased consumption generates effects that may be catastrophic for the future of the planet (climate change, environmental imbalance), should this growth conform to the patterns followed, up to recent times, by most industrialized countries. Reduction of greenhouse gas emissions, development of new energy sources and energy efficiency are seen as the major challenges to be taken up for the world of tomorrow. In France, the National Energy Debate indeed emphasized, in 2003, the requirement to control both demand for, and offer of, energy, through a strategic orientation law for energy. The French position corresponds to a slightly singular situation - and a privileged one, compared to other countries - owing to massive use of nuclear power for electricity generation. This option allows France to be responsible for a mere 2% of worldwide greenhouse gas emissions. Real advances can nonetheless still be achieved as regards improved energy efficiency, particularly in the transportation and residential-tertiary sectors, following the lead, in this respect, shown by industry. These two sectors indeed account for over half of the country CO2 emissions (26% and 25% respectively). With respect to transportation, the work carried out by CEA on the hydrogen pathway, energy converters, and electricity storage has been covered by the preceding chapters. As regards housing, a topic addressed by one of the papers in this chapter, investigations at CEA concern integration of the various devices enabling value-added use of renewable energies. At the same time, the organization is carrying through its activity in the extensive area of heat exchangers, allowing industry to benefit from improved understanding in the modeling of flows.

    Energy storage technology is critical if the U.S. is to achieve more than 25% penetration of renewable electrical energy, given the intermittency of wind and solar. Energy density is a critical parameter in the economic viability of any energy storage system with liquid fuels being 10 to 100 times better than batteries. However, the economical conversion of electricity to fuel still presents significant technical challenges. This project addressed these challenges by focusing on a specific approach: efficient processes to convert electricity, water and nitrogen to ammonia. Ammonia has many attributes that make it the ideal energy storage compound. The feed stocks are plentiful, ammonia is easily liquefied and routinely stored in large volumes in cheap containers, and it has exceptional energy density for grid scale electrical energy storage. Ammonia can be oxidized efficiently in fuel cells or advanced Carnot cycle engines yielding water and nitrogen as end products. Because of the high energy density and low reactivity of ammonia, the capital cost for grid storage will be lower than any other storage application. This project developed the theoretical foundations of N2 catalysis on specific catalysts and provided for the first time experimental evidence for activation of Mo 2N based catalysts. Theory also revealed that the N atom adsorbed in the bridging position between two metal atoms is the critical step for catalysis. Simple electrochemical ammonia production reactors were designed and built in this project using two novel electrolyte systems. The first one demonstrated the use of ionic liquid electrolytes at room temperature and the second the use of pyrophosphate based electrolytes at intermediate temperatures (200 – 300 ºC). The mechanism of high proton conduction in the pyrophosphate materials was found to be associated with a polyphosphate second phase contrary to literature claims and ammonia production rates as high as 5X 10

    The objective of the Symposium for Public Awareness on Energy was to provide an information exchange among the members of the technical community and the public, civic, fraternal, service, and labor organizations on timely energy-related issues. The 1977 symposium was oriented toward state and local governmental officials in the southeastern states. Since it is these officials who have the responsibility for the development and actualization of local energy strategies, the program was directed toward providing information which would be of help to them in considering energy plans. The symposium presentations featured speakers who are recognized in many facets of the energy field. A variety of views were expressed and a number of policy alternatives were suggested. It is hoped that the presentations provided the motivation for the audience to return to their respective communities with a new and expanded perspective regarding energy issues and policies. The private and public organizations represented at the symposium can continue to provide pertinent information to those who are interested. A separate abstract was prepared for each of the 9 presentations.

  5. Energy resources

    International Nuclear Information System (INIS)

    Cuba, like most island nations, lacks a large energy resource base and satisfies most of its energy needs with imported fossil fuels. The evaluation of the availability of domestic energy reserves and resources, as well as their future extraction potential, is a necessary task in an assessment of sustainable energy development. When estimates of potential availability of fossil fuels are carried out, a distinction is made between reserves and resources. In this study, reserves are known quantities that can be extracted with current technology at current prices. Resources are either less certain as to their existence or known to be technically or economically unfeasible or both. In the case of renewables, the concept of resources needs to be modified. Renewable resources are part of a natural flow that can be regenerated in a time frame that is suitable for human activities. For this reason, it is necessary to refer to renewable energy potential rather than resources. Both resources and reserves change as new technologies become available or due to changes in the market. This is another reason to distinguish between resources, reserves and energy potential

    For solving the problems of environmental sanitation in developing countries, assistance projects in respect of the supply of safe water and the maintenance of urine/waste water treating facility are developed by the aid organizations and civilian organizations of Japan. However, the funds, technology, capable persons, materials, etc. in developing countries are restricted in various ways, so there are a lot of cases that can not be approached by the methods in developed countries. In this paper, the appropriate technology in the environmental sanitation field in developing countries is described with practical cases. For example, there is a case that, regarding the wastewater treatment, a stabilizing pool is a safer treatment than the activated sludge process. Since the retention time in the stabilizing pool is longer than 10 days, parasitic worms in feces is settled and germs die out considerably. On the other hand, although the activated sludge process has a good removal rate of BOD, it is not an appropriate technology in developing countries because the removal rate of parasitic worms and germs are not good thus a disinfection is necessary, and additionally the electric power is rather consumed in operation. 2 refs., 4 figs., 1 tab.

Its application to the cutting of stainless steel plates has attracted attention. Cutting tests of SUS304 were conducted using high power YAG laser. Cutting of SUS304 plate with a thickness of 40 mm could be successfully done at the power of 3.5 kW. Cutting tests of SUS304 pipes with a thickness of 8 mm in water under the depth of 20 m were also conducted using air as assist gas at the power of 2.5 kW. Excellent results were obtained without scale deposition. For the tests by the composite beam using 3 kW and 4 kW systems, SUS304 plate with a thickness of 50 mm could be cut at the cutting speed of 0.1 m/min. Laser cutting of pipes from the internal surface was conducted using a newly developed small machining head which can rotate in the peripheral direction. Excellent quality for welding was confirmed. Cutting speed and plate thickness were improved by combining water jet cutter and YAG laser unit. 6 refs., 10 figs.

    A coating system is introduced as a liquid atomization technique for oral administration drug applied to the pharmaceutical process. Controlled release of drug dissolution in the human body is important. How to dissolve the drug by coating granules is described here. For example, the core of a drug granule is made up by spherical granulated sucrose, the intermediate layer as a main element by theophylline which is an asthma medicine, the outer layer by an ethylcellulose film. Theophylline takes 30 minutes to dissolve and the ethylcellulose-coated granule does more than 16 hours. A fluidized tumbled bed type coating apparatus is developed to prevent unevenness, adhesion and aggregation. Even in the same chemical species, the dissolution speed differs in a crystal type, crystalline or amorphous and anhydrous or hydrate. Acceleration of the drug dissolution is studied. A suspension which is an ethanol solution of hydroxy propy/cellulose with supersaturated antiflammatory drug, atomized by a jetcoating system, is coated on the surface of potato starch powder. The drug as a main element shows only a 10% dissolution rate in 8 hours. On the other hand, the drug coated show a 100% dissolution rate in 2 hours. This is because the coating crystallizes the drug itself in the film and promotes its dissolution. 6 refs., 8 figs.

    Investigation has been made on the current status of food sanitation controlling technologies. Eighty percent of food poisoning is caused by bacte such as Salmonera, enteritis vibrio, staphylococcus, and pathogenic colibacillus. Putrefaction as the cause for food poisoning occurs from proliferation of different microorganisms. Heating sterilization is the main method being performed, but non-heating method may include sterilization by flash and high voltage pulse discharge in addition to ultra-high pressure and ultraviolet ray sterilization. As a result of the questionnaire survey, what is extracted as the problems in the food sanitation controlling technologies is to establish a rinsing and sterilizing method with large sterilization effect, an effective sterilizing method and thawing of processed marine products, and a cooling method in food processing. Increasingly demanded for the future is to develop a foodstuff sanitation control system using as the core the hazard analysis critical control point (HACCP, a quality control program developed by the U.S. NASA to ensure safety in manufacturing space food), and micro-organism control and sterilizing technologies to support the above system. The flash pulse and high-voltage pulse sterilizing technologies as the non-heating sterilizing technology are more effective than the conventional heating sterilization methods also from the aspect of quality retention after sterilization. More active development thereof is desired. (NEDO)

    A joint development has been made with Tokyo Electric Power Company on a system to detect partial discharge occurring at an anomaly of a device by means of using a sensor with fibers added with coloring matters as a technology to diagnose insulation in gas insulated switches (GIS). This system can be fitted to existing GISs because of its structure to mount the sensor onto a flange in the hand hole of a GIS. In addition, the fluorescent fiber sensor has a feature that it is not affected by incoming noise because the sensor captures a partial discharge directly. Performances of partial discharge detection of this system include: (1) it detects gas in about one minute by each gas section of a GIS; (2) the detection sensitivity for a partial discharge is about 10 pC of electric charge of a discharge; and (3) detection of a discharge at a position where partial discharge light is not directed directly to a sensor can also be detected by reflected light from GIS tank walls.

    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.

    Because of the long history of hydroelectric equipment in Japan, renewal of a large number of existing over-aged equipment is in progress. While changes in environment surrounding hydroelectric equipment and recent technological development have diversified requirements for repair and renewal of hydroelectric equipment and technologies to meet them. This paper presents the recent technological trend and the typical examples of modernization technologies for such over-aged equipment. The water supply equipment of hydroelectric power stations is damaged frequently and takes much time in maintenance. Waterless technologies requiring no water supply equipment were thus established such as air cooling of hydraulic turbine bearings and ceramic water seal equipment. On oilless (greaseless) technology, newly developed water lubrication bearings and electric servo motors are in use for guide vane operation. On generator, shaft seal equipment using magnetic fluid and improved air ducts sucking no outside air for preventing insulation resistance from reduction are in use. 6 figs., 2 tabs.

  12. Energy challenges

    International Nuclear Information System (INIS)

    Satisfying the world's insatiable appetite for fuel without destroying the environment is the biggest challenge facing the energy industry. World energy consumption is expected to soar by 50% to a staggering 180 000 GW h per year by 2020, with the developing world demanding an ever-increasing share. Although oil and natural-gas reserves will last for several more decades, environmental concerns are increasingly dominating the agenda. Last year 178 countries agreed to a watered-down version of the original Kyoto protocol, which was designed to reduce the emissions of greenhouse gases from industrialized countries by an average of 5.2% below 1990 levels. Under the new agreement, dubbed 'Kyoto lite' by environmentalists, emissions will be cut by just 2%. The relaxed targets are still not enough to convince the US, the world's biggest polluter, to sign the Kyoto treaty. Renewable technologies still make up less than 1% of the world's commercial energy. Distributed power is also likely to emerge from the development of fuel cells - devices that convert the chemical energy of hydrogen and oxygen directly into electricity, with only water as a by-product. The move away from carbon-based fossil fuels to hydrogen is also driving the hydrogen economy. A longer-term possibility is nuclear fusion. Despite the enormous progress in the performance of experiments over the past 30 years, nuclear fusion is still decades away from generating electricity. Advocates of fusion power claim that it could be a safe and sustainable source of energy that does not produce any greenhouse gases or long-lived nuclear waste. However, physicists have still to demonstrate that the energy produced by the fusion of deuterium and tritium can be sustained. Advances in physics and engineering are making energy from renewable sources increasingly affordable. But political will - as well as scientific progress - is just as crucial for safeguarding the environment for generations to come

    Geothermal technologies use renewable energy resources to generate electricity and direct use of heat while producing very low levels of greenhouse-gas (GHG) emissions. Geothermal energy is stored in rocks and in fluids circulating in the underground. Electricity generation usually requires geothermal resources temperatures of over 100°C. For heating, geothermal resources spanning a wider range of temperatures can be used in applications such as space and district heating (and cooling, with proper technology), spa and swimming pool heating, greenhouse and soil heating, aquaculture pond heating, industrial process heating and snow melting. Geothermal technology, which has focused so far on extracting naturally heated steam or hot water from natural hydrothermal reservoirs, is developing to more advanced techniques to exploit the heat also where underground fluids are scarce and to use the Earth as a potential energy battery, by storing heat. The success of the research will enable energy recovery and utilization from a much larger fraction of the accessible thermal energy in the Earth's crust.

    The purpose of the Energy Deskbook is to serve as a convenient reference to definitions of energy-related terms and descriptions of current and potential energy sources and their utilization. The material is presented at a low technical level with emphasis on general principles, which are not difficult to understand, rather than technology. The entries vary in length from a few lines to several pages, according to circumstances. As a general rule, each topic is defined and outlined in the first paragraph; this may be followed by a more detailed treatment, as required. An important feature of the Deskbook is the use of boldface (heavy) type for cross references. Words in the text set in boldface are the titles of articles where the particular subjects are described.

    Three major concerns face mankind's future: the impending energy crisis as caused by the depletion of the world's fossil fuel reserves, world atmospheric pollution as caused by the burning of these fuels, and mankind's destruction if the vast energy contained in nuclear weapons stockpiles is released in a global conflict. This paper describes an ambitious, combined solution to these problems by the use of deep underground detonations of thermonuclear devices/bombs to provide a virtually pollution free, world energy source into the far distant future, while achieving a significant increase in mutual trust between the superpowers and all nations. The key is believed to be thermonuclear geothermal stimulation to produce the electrical power needed for a hydrogen economy

  18. Geothermal energy

    International Nuclear Information System (INIS)

    Geothermal energy is the natural heat of the earth. It represents an inexhaustible source of energy. In many countries, which are mostly located within the geothermal belts of the world, geothermal energy is being used since many decades for electricity generation and direct heating applications comprising municipal, industrial and agricultural heating. Outside the geothermal anomalous volcanic regions, hot ground water from deep rock formations at temperatures above 70oC is used for process heat and space heating. Low prices for gas and oil hinder the development of geothermal plants in areas outside positive geothermal anomalies; the cost of drilling to reach depths, where temperatures are above 50oC to 70oC, is high. The necessary total investment per MWth installed capacity is in the order of 5 Mio- DM/MWth (3 Mio $/MWth). Experience shows, that an economic break even with oil is reached at an oil price of 30$ per barrel or if an adequate bonus for the clean, environmentally compatible production of geothermal heat is granted. Worldwide the installed electric capacity of geothermal power plants is approximately 6 000 MWe. About 15 000 MWth of thermal capacity is being extracted for process heat and space heat. The importance of the terrestrial heat as an energy resource would be substantially increased, if the heat, stored in the hot crystalline basement could be extracted at economical production costs. Geothermal energy is a competitive energy source in areas with high geothermal gradients (relative low cost for drilling) and would be competitive in areas with normal geothermal gradients, if a fair compensation for environmental implications from fossil and nuclear power production would be granted.

    Bioenergy systems can provide an energy supply that is environmentally sound and sustainable, although, like all energy systems, they have an environmental impact. The impact often depends more on the way the whole system is managed than on the fuel or on the conversion technology. The authors first describe traditional biomass systems: combustion and deforestation; health impact; charcoal conversion; and agricultural residues. A discussion of modern biomass systems follows: biogas; producer gas; alcohol fuels; modern wood fuel resources; and modern biomass combustion. The issue of bioenergy and the environment (land use; air pollution; water; socioeconomic impacts) and a discussion of sustainable bioenergy use complete the paper. 53 refs., 9 figs., 14 tabs

    International Nuclear Information System (INIS)

    Access to clean energy is essential for alleviating poverty and fulfilling sustainable development goals. Energy is both an engine of development and a source of many of the problems we face. Approximately four fifths of all the energy used worldwide comes from fossil fuels - and they are also the main contributors to environmental and health problems at local, regional and global levels. Meanwhile, much biomass in the form of wood and agricultural waste continues to be used in inefficient cooking stoves in rural areas - a major source of health problems, which mainly affect poor women and children. Providing alternatives to substitute for wood fuels and to support new opportunities for earning income would address the needs of more than a half billion poor people around the world. Access to clean energy may by no means be sufficient in itself to ensure sustainable development, but it is an essential component of strategies for rural jobs, education, food, security, water supplies, urban and rural public health, local self-sufficiency and a host of other development benefits

    Toward the future, the petroleum could stop to be the main energy source in the world and the oil companies will only survive if they are adjusted to the new winds that blow in the general energy sector. It will no longer be enough to be the owner of the resource (petroleum or gas) so that a company subsists and be profitable in the long term. The future, it will depend in great measure of the vision with which the oil companies face the globalization concept that begins to experience the world in the energy sector. Concepts like globalization, competition, integration and diversification is something that the companies of the hydrocarbons sector will have very present. Globalization means that it should be been attentive to what happens in the world, beyond of the limits of its territory, or to be caught by competitive surprises that can originate in very distant places. The search of cleaner and friendlier energy sources with the means it is not the only threat that it should fear the petroleum. Their substitution for electricity in the big projects of massive transport, the technology of the communications, the optic fiber and the same relationships with the aboriginal communities are aspects that also compete with the future of the petroleum

    The ovulatory activity in the livestock depends on the readiness of nutritious energy with relationship to its use for the nursing. During the early nursing the cup of increment in the production of milk exceeds to the consumption of food, the difference in the energy consumption of the diet with relationship to the energy used for production is a negative energy balance. During the first weeks of nursing this reaches their maximum and it diminishes slowly with the increment in the consumption of dry matter. This first metabolic sign is in an increment in the pulses of hormone luteinizant that acts as and stimulate for the ovary and that with a great readiness of insulin, it takes to the ovarian follicles to respond to the stimulus. The sub-alimentation seems to affect the hypothalamic function and ovarian. The return to the positive energy balance in cows highly producers can be accelerated by the consumption of protected fat. The functions of the lipids are to provide energy for normal maintenance and production, to serve as source of essential fatty acids and eat payee of liposoluble vitamins. The importance of the addition of vegetable fat is that this is not degraded in the rumen but rather it is digested in its entirety in abomasa and absorbed in intestine. The addition of a source of Ca to diets with fats promotes the formation of insoluble soaps achieving that the fat doesn't inhibit the fiber fermentation; the chloride of Ca to be of high solubility in water it is completely ionized in rumen and it is more efficient in the formation of insoluble soaps of Ca. The addition of fat in the diet bears increase in the production of N microbial, inhibition of methane formation, increase and change in population of bacteria and mushrooms. The efficiency of the fat is superior when sources of fatty acids of long chain are used, the employment of these, in its protected form, in a diet, stimulates the number of follicles and it increases its size.

    The article discusses the identification of efficiencies that can minimise transaction costs in energy trading and marketing. The article describes what is meant by 'trade management'. It is argued that a trade management system should be able to dovetail with existing or future ERP, advanced risk management, and financial management systems, to provide total enterprise integration. With the right trade management systems, traders have all the necessary information to help them manage exposure to financial risks in a world where energy trading companies are forced to accept very small margins. A trade management system can cover many aspects of a business including the winning of contracts for transportation deals, including rail, car, truck, barge and pipeline. There appears to be unprecedented opportunities for companies specialising in development and provision of trade management systems

  18. Cold energy

    International Nuclear Information System (INIS)

    Deviations in Q for resonant superconducting radio frequency niobium accelerator cavities are generally correlated with resistivity loss mechanisms. Field dependent Qs are not well modeled by these classical loss mechanisms, but rather can represent a form of precision cavity surface thermometry. When the field dependent Q variation shows improvement with increasing B field level the classical treatment of this problem is inadequate. To justify this behavior hydrogen as a ubiquitous impurity in niobium, which creates measurable property changes, even at very low concentrations is typically considered the cause of such anomalous behavior. This maybe the case in some instances, but more importantly any system operating with a highly coherent field with a significant time dependent magnetic component at near 2° K will have the ability to organize the remaining free spins within the London penetration depth to form a coupled energy reservoir in the form of low mass spin waves. The niobium resonant cavities are composed of a single isotope with a large nuclear spin. When the other loss mechanisms are stripped away this may be the gain medium activated by the low level residual magnetic fields. It was found that one resonant cavity heat treatment produced optimum surface properties and then functioned as a MASER extracting energy from the 2° K thermal bath while cooling the cavity walls. The cavity operating in this mode is a simulator of what can take place in the wider but not colder universe using the cosmic microwave background (CMB) as a thermal source. The low mass, long lifetimes, and the scale of the magnetic spin waves on the weakly magnetized interstellar medium allows energy to be stored that is many orders of magnitude colder than the cosmic microwave background. A linear accelerator cavity becomes a tool to explore the properties of the long wave length magnetic spin waves that populate this cold low energy regime

  20. Geothermal energy

    International Nuclear Information System (INIS)

    To put it simply, geothermal power is the utilization of the earth's natural heat. At many locations around the world, heat from the earth's mantle approaches close to the surface, chiefly in volcanically and or seismically active zones. Magnificent examples include the Big Island of Hawaii, Mount Pinatubo in the Philippines, Yellowstone, and Mt. St. Helens. Commercially viable sources of geothermal energy exist when the heat is close to the surface, a source of water can act as a heat transfer medium, and a geologic setting exists that contains the heat so it concentrates and doesn't dissipate. In addition, the heat must be adequate to provide temperatures at least above 290 degrees F to take advantage of currently available energy conversion technologies. This paper is directed toward the utilization of geothermal energy for power generation. It describes the industry today, the author's view of the benefits of geothermal power, and some measures that could increase the beneficial use of this power source

    Deacon, R.; DeCanio, S.; Frech, H.E. III; Johnson, M.B.

    1990-01-01

    In this book, the authors have produced an analysis of state energy taxation. Their factual findings are of particular relevance to California and other states in their consideration of severance taxes on oil production. It turns out, for example, that while California's tax burden on oil producers is slightly below average among the states, the combined revenues from taxes and royalties (expressed as a percent of the value of production) indicate that California is not easy on oil producers. In fact, California's oil tax system appears to be particularly well suited to its oil industry. Much of the production in the state is relatively high-cost and economically marginal. The state must tread carefully in taxing this production, lest it force it to be curtailed.

  12. Energy policy

    International Nuclear Information System (INIS)

    Gasoline consumption by passenger cars and light trucks is a major source of air pollution. It also adds to the economy's dependence on petroleum and vulnerability to oil price shocks. Despite these environmental and other costs, called external cost, the price of gasoline, adjusted for inflation, has generally been declining since 1985, encouraging increased consumption. This paper reports that with these concerns in mind, the Chairman, Subcommittee on Environment, House Committee on Science, Space, and Technology, requested that GAO assess policy options for addressing the external costs of gasoline consumption. To do this, GAO identified six major policy options and evaluated whether they addressed several relevant objectives, including economic growth, environmental quality, equity, petroleum conservation, visibility of costs, energy security, traffic congestion, competitiveness, and administrative feasibility

  13. Energy supply and nuclear energy

    International Nuclear Information System (INIS)

    The author emphasizes the necessity and importance of nuclear energy for the energy supply and stresses the point that it is extremely important to return to objective arguments instead of having emotional disputes. In this connection, it would be necessary for the ministries in question to have clear-cut political responsibility from which, under no circumstances, they may escape, and which they cannot pass on to the courts either. Within the framework of listing present problems, the author is concerned with the possibility of improved site planning, the introduction of a plan approval procedure and questions concerning immediately enforceable nuclear licences. He also deals with a proposal, repeatedly made, to improve nuclear licensing procedures on the one hand by introducing a project-free site-appointment procedure, and on the other hand by introducing a simplified licensing procedure for facilities of the same kind. Splitting the procedure into site and facility would make sense solely for the reason that in many cases the objections are, above all, directed against the site. (HP)

    Arctic Energy Resources is a volume of 26 papers recording the proceedings of the Comite' Arctique International Conference, held at the Veritas Centre, Oslo, Norway, September 22-24, 1982. This was the fourth of a series of meetings on the Arctic organized by the Comite', an organization established in the Principality of Monaco with the active support of H.S.H. Prince Rainer III. The fourth Conference was opened by H.R.H. Crown Prins Harald of Norway, a noble beginning for a noble objective.The North Polar Region has drawn world attention recently because of several large hydrocarbon and other mineral discoveries and because of major political and environmental actions in the North American Arctic. Since 1923 when Naval Petroleum Reserve number 4 (NPR-4) was established, northern Alaska has been considered a major petroleum province. It was first explored systematically with modern techniques from 1943 to 1953. In 1958, Alaska became a state, and both federal and state lands in northern Alaska were available for private exploration. Building on the knowledge base provided by the Pet-4 program and its spinoff research laboratory at Barrow, industry explored the area east of NPR-4 and discovered the largest hydrocarbon accumulation (9.6 bbl crude oil and 26 Tcf (trillion cubic feet) gas) in North America at Prudhoe Bay. Concerns for environmental impacts, including oil spills, led to the passing of the National Environmental Policy Act in 1969. In 1970, over 9 million acres were set aside, now known as the Arctic National Wildlife Range, and in 1971 the Alaska Native Claims Settlement Act was passed by the U.S. Congress. The Arab oil embargo of 1973 heightened the energy crisis and changed the economic basis for further exploration in the Arctic. The convergence of these events dramatically changed the balance of power and the pace of activity in the North American Arctic.

  11. Fusion energy

    International Nuclear Information System (INIS)

    The main purpose of the International Thermonuclear Experimental Reactor (ITER) is to develop an experimental fusion reactor through the united efforts of many technologically advanced countries. The ITER terms of reference, issued jointly by the European Community, Japan, the USSR, and the United States, call for an integrated international design activity and constitute the basis of current activities. Joint work on ITER is carried out under the auspices of the International Atomic Energy Agency (IAEA), according to the terms of quadripartite agreement reached between the European Community, Japan, the USSR, and the United States. The site for joint technical work sessions is at the MaxPlanck Institute of Plasma Physics. Garching, Federal Republic of Germany. The ITER activities have two phases: a definition phase performed in 1988 and the present design phase (1989--1990). During the definition phase, a set of ITER technical characteristics and supporting research and development (R ampersand D) activities were developed and reported. The present conceptual design phase of ITER lasts until the end of 1990. The objectives of this phase are to develop the design of ITER, perform a safety and environmental analysis, develop site requirements, define future R ampersand D needs, and estimate cost, manpower, and schedule for construction and operation. A final report will be submitted at the end of 1990. This paper summarizes progress in the ITER program during the 1989 design phase

    1990-01-01

    In 1989, the U.S. photovoltaic industry enjoyed a growth rate of 30 percent in sales for the second year in a row. This sends a message that the way we think about electricity is changing. Instead of big energy projects that perpetuate environmental and economic damage, there is a growing trend toward small renewable technologies that are well matched to end-user needs and operating conditions. As demand grows and markets expand, investment capital will be drawn to the industry and new growth trends will emerge. The photovoltaic industry around the world achieved record shipments also. Worldwide shipments of photovoltaic (PV) modules for 1989 totaled more than 40 megawatts (MW), nearly a 20 percent increase over last year's shipments. The previous two years showed increases in worldwide shipments of 23 and 25 percent, respectively. If this growth rate continues through the 1990s, as industry back orders would indicate, 300 to 1000 MW of PV-supplied power could be on line by 2000. Photovoltaic systems have low environmental impact and they are inexpensive to operate and maintain. Using solid-state technology, PV systems directly convert sunlight to electricity without high-temperature fluids or moving parts that could cause mechanical failure. This makes the technology very reliable.

    To ensure the economic and social development of the countries of Latin America and the Caribbean, one of the problems that have to be addressed is bridging the technology gap that separates the region's countries from those of the so-called First World. In order to achieve this, the indispensable first step is to learn about, evaluate, orient, and promote scientific and technical training of the region's human resources. In this context, OLADE, with the cooperation of the Andean Development Corporation (CAF), undertook an inventory of the region's energy sector training supply and demand in order to identify both the needs of the institutions involved in the sector's development and the training centers that can meet these needs. In order to mitigate and eliminate the impact of Y2K problem, governments, companies and other sector entities are carrying out specific actions, which are described along with the preventive activities that are being implemented by OLADES's Permanent Secretariat.

    Eleven years ago Hechengli, in the northeast corner of China, began planning to become an Ecological Village in Jilin Province. Now it is pioneering again, as host to a revolutionary new energy project which could prove a model for China and much of the developing world. A combined heat and power plant, to be fuelled by corn stalks and other agricultural wastes, has been built on a hill overlooking the village of 224 households in one of the most fertile parts of the country. Financed jointly by the local Jilin Provincial Government and the United Nations Development Programme (UNDP), it is designed to produce cooking gas, heat and electricity simultaneously and to demonstrate the technical, economic and market viability of a modern biomass gasification system. The UNDP funds are being provided through a grant from the UN Foundation. Jilin Province, home to just 2 per cent of China's population, produces 14 per cent of its corn. The corn stalks currently pose a waste problem, but could become a valuable local resource to reduce poverty and support sustainable development. Clean, low-cost heat and power, based on such biomass, could increase living standards, promote industry and create jobs here and in rural areas throughout developing countries - while cutting dangerous indoor air pollution from traditional cooking stoves and combating global warming

    Protocols of quantum energy teleportation (QET), while retaining causality and local energy conservation, enable the transportation of energy from a subsystem of a many-body quantum system to a distant subsystem by local operations and classical communication through ground-state entanglement. We prove two energy-entanglement inequalities for a minimal QET model. These relations help us to gain a profound understanding of entanglement itself as a physical resource by relating entanglement to energy as an evident physical resource.

    2002-03-01

    Renewable energy offers the possibility of providing a complete, sustainable energy infrastructure without anthropogenic emission of CO2. Large-scale implementation of renewable technologies would eliminate the need to develop and implement sequestration systems, by reducing the use of, and ultimately eliminating fossil based energy production. Renewable energy also offers energy security because indigenous resources are sufficient. The major renewable energy systems include phovoltaics (solar cells), solar thermal (electric and thermal), wind, biomass (plants and trees), hydroelectric, ocean, and geothermal. Given the intermittent nature of solar energy, only those energy systems that are coupled to an energy storage technology will be viable. Among the energy storage technologies are hydrogen, batteries, flywheels, superconductivity, ultracapacitors, pumped hydro, molten salts (for thermal storage), and compressed gas. One of the most versatile energy storage systems and the best energy carrier for transportation is hydrogen. This talk will review some of the basic renewable energy systems, present possible pathways for the implementation of hydrogen into the energy infrastructure and offer research areas that need to be addressed to increase the viability of these renewable energy technologies.

  20. Domestic energy use and householders' energy behaviour

    International Nuclear Information System (INIS)

    This paper discusses domestic energy use and energy behaviour. It shows some improvement in domestic energy consumption and adoption of good energy practice. The survey conducted indicated that 35% of homes could improve their energy efficiency by improved tank insulation. In the last 5 years condensing boilers have been installed only in 3% of homes, indicating that householders are unaware of their advantages. Although 88% of surveyed homes had purchased a major appliance in the last 2 years, only 16% had any idea of the energy rating of their new appliances. Use of energy saving light bulbs is predominant in kitchens compared to other rooms. 70–80% of householders undertook some kind of day-to-day energy efficiency measures. 20–35% of householders would like to invest in energy-saving measures but found cost to be a key barrier. Approximately 84% of those surveyed were unaware of the energy rating of their household appliances. Price and brand were the most important factors determining the purchase of a new appliance. Significant energy-saving could be achieved by providing appropriate information to the general public regarding temperature control, efficiency of appliances and energy-saving heating systems. - Highlights: ▶ Good practice in household energy use is being adopted but actual use is rising. ▶ Cost is dominant in energy related decisions purchasing of household appliances. ▶ Energy behaviour is improving but level of awareness needs more work.

  1. Geothermal Energy : An Alternative Source of Energy

    2014-04-01

    Full Text Available Nowadays renewable sources are preferred over the non renewable source to generate the energy. The rapid rates of exhausting non-renewable resources have completed us to look out for new avenues in energy generation. According to global energy scenario, developed countries are adopting renewable resources as major source of energy. Geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. Geothermal energy is derived from the hot interior of the earth. The earth is a reservoir of heat energy, most of which is buried and is observed during episodes of volcanic eruption at the surfaces. Geothermal is one of the most promising renewable source of energy which is plentiful, eco-friendly, reliable and clean source of energy available in earth crust. In our country there is wide scope for the utilization of geothermal energy with proper strategically approach to meet the energy requirement. The future prospects of this heat energy as a sustainable source of renewable energy are indeed promising. Today India is the fifth largest consumer of electricity and by 2030 it will become third largest overtaking Japan and Russia according to statistical data available by Energy Planning Commission, Government of India.

    The aim of this book is to illustrate the interaction between architecture and energy in an overall perspective starting from the new energy requirements. Architects make a lot of form related outlines early in the design process, and these have significant consequences for the energy consumption. Furthermore, the new energy requirements start from an overall evaluation, during which the architectural form is of decisive importance to minimization of the energy consumption. The book focuses on four themes: a) day lighting, which plays a decisive part in relation to our health and wellness inside buildings, b) solar heating; passive solar heating has traditionally been playing an important part in low-energy architecture, c) rough house; choice of materials can both increase and decrease buildings' energy consumption, and d) technology; modern buildings use a number of energy demanding installations, therefore the interaction between technology and energy is examined.

  15. Urban energy consumption mapping for energy management

    International Nuclear Information System (INIS)

    The amount of energy consumption of individual buildings is a widely discussed theme. However, there are few studies that have analyzed the consumption of energy by groups of buildings. This work aims to develop a model able to estimate the energy consumption by residential sectors, in different areas inside a city, through the adoption of an energy planning methodology using the city of Belo Horizonte, Brazil as a case study. In this model, the most important variables of consumption behavior are related to the economy. The methodology coupled different approaches. Its first step was to survey the ownership of appliances and the socioeconomic profile of households in each region inside of the city, through the statistical analysis of census data. The second step was to characterize the average energy consumption by typical residential equipment. Then, it was possible to compute the energy consumption according to equipment and region. Finally, the modeled municipal energy consumption was compared with that recorded by the energy utility company. As a result, maps of energy consumed by end use are presented for the years 1991, 2000, and 2007. The conclusions of this work can be applied in energy planning projections and in local urban planning. - Highlights: • We develop a model for calculating location-specific energy consumption for cities. • The methodology couples different approaches to the traditional energy planning. • As a result, we produce maps of the spatial distribution of energy consumption. • Those maps allow the evaluation of the impacts of energy consumption on urban areas

    A new noncontacting dressing method using a laser as a tool has been studied and developed, in order to develop environment-compatible, energy-saving type machining machines. In this study, a cup-shaped grinding stone is developed for grinding performance testing by micron-order diamond abrasive powder, used for producing a grinding stone of superthin blades, is mixed with a cast iron binder, molded and sintered. In the grinding performance test, zirconia as a work is ground at a constant pressure to the grinding stone working surface before and after the laser-aided dressing, to analyze grinding/removal efficiency and grinding resistance. The grinding stone working surface conditions are observed by a scanning electron microscope after the laser-aided dressing, to correlate the surface conditions with the grinding data. It is found that the laser-aided dressing method needs no lubricant, is clean, cutting grinding time when incorporated in the machining process, suitable for grinding stone of low stiffness and ultrathin blades by use of ultrafine abrasive grains, suffering no exfoliation of the diamond grains, and hence economical.

Low energy efficiency has become one of the main factors of the crisis in the Ukrainian economy. The most relevant scientific and methodical approaches to assessment of the level of energy consumption and saving are indicated. The comparative analysis of annual energy use has been made. A potential to solve energy supply problems is strongly correlated with the ability to ensure the innovative development of economy for efficient and economical use of existing and imported energy resources. The ways for reducing of energy resource consumption have been suggested. Creation of technological conditions for the use of alternative energy sources is considered to be rational also. The development of renewable sources of energy (alternative and renewable energy sources will provide a significant effect in reducing the use of traditional energy sources, harmful emissions and greenhouse gas. Under these conditions, increasing of energy efficiency of economy and its competitiveness can be real. Improvement of environmental and social conditions of citizens of the country will mark a positive step towards the EU, and also will cancel some problems of the future generation.

  3. Energy levy and the domestic energy consumption

    International Nuclear Information System (INIS)

    The Dutch government considers the implementation of a regulating energy levy to realize the policy aims with regard to energy conservation and the environment. For the sector households the aim is to improve the energy efficiency by 25% between 1990 and 2000. The impact of the energy prices on the energy consumption of households is discussed. An increase of the energy price can effect the household energy consumption in two ways. One is so-called good housekeeping, i.e. saving energy by means of changes in the pattern of behavior. Another way is by means of investments with long term effects: thermal insulation, acquisition of energy saving appliances. An analysis is carried out for both ways, based on CBS (Central Bureau for Statistics in the Netherlands) data of households in the period 1981-1987. First a regression analysis is used to determine the effect of good housekeeping. The changes with regard to sustainable aspects of the energy consumption have been analyzed by means of a logit-model. This model can explain the chance that a certain condition or event can occur, respectively will happen. On the basis of the estimated models simulations were carried out to determine the effect of doubling the energy prices on the energy consumption. Finally attention is paid to the effects on the income for different income groups as a result of doubling the energy prices. 2 tabs

  16. Energy saving synergies in national energy systems

    DEFF Research Database (Denmark)

    Thellufsen, Jakob Zinck; Lund, Henrik

    2015-01-01

    In the transition towards a 100% renewable energy system, energy savings are essential. The possibility of energy savings through conservation or efficiency increases can be identified in, for instance, the heating and electricity sectors, in industry, and in transport. Several studies point...... to various optimal levels of savings in the different sectors of the energy system. However, these studies do not investigate the idea of energy savings being system dependent. This paper argues that such system dependency is critical to understand, as it does not make sense to analyse an energy saving...... without taking into account the actual benefit of the saving in relation to the energy system. The study therefore identifies a need to understand how saving methods may interact with each other and the system in which they are conducted. By using energy system analysis to do hourly simulation...

  18. The International Energy Agency's world energy outlook

    International Nuclear Information System (INIS)

    The 1996 edition of the World Energy Outlook to 2010 was reviewed. An overview of the energy projections was provided based on assumptions about economic growth and energy prices, geological potential, technological developments, the availability of traditional fuels outside the OECD and the future preferences of energy users. Demand vs. price movements were modelled, based on 'capacity constraints' and 'energy saving ' scenarios. Three major conclusions derived from the projections were: (1) world primary energy demand will grow steadily as it has over the past two decades, (2) fossil fuels will account for 90 per cent of total primary energy demand in 2010, and (3) a structural shift in the shares of different regions in world energy demand is likely to occur, i.e., the OECD share will fall in favor of the share of the ROW (rest of the world). 4 tabs., 9 figs

  19. Energy in Croatia 2003. Annual Energy Report

    International Nuclear Information System (INIS)

    Reports have kept domestic and international audience continuously informed about the latest relations and developments in the Croatian energy system. Annual report presents all characteristic indicators of the Croatian energy system in 2003, outlines their development over a longer past period, and suggests a future course of development of basic energy system indicators. Total primary energy supply in the Republic of Croatia in 2003 was 5.2 percent higher compared to the previous year. The gross domestic product increased by 4.3 percent over the same period. This means that energy intensity, primary energy supply per unit of gross domestic product, increased by 0.9 percent. Compared to the european Union average Croatian energy intensity was approximately 32 percent higher. Total primary energy production, on the other hand, decreased by 1.1 percent compared to 2002. This means that primary energy self-supply, which fell to 46.4 percent, reached its lowest level to-date in the observed period. The remaining energy needs were met by imports, which increased by 1.7 percent. In the structure of total primary energy supply, decrease has been observed only in energy conversion losses, while all other categories increased. Final energy demand increased by 6.7 percent in 2003, with the levels recorded in different sectors ranging from 2.5 percent in industry to 7.5 and 8 percent in transport and other sectors, respectively. In terms of final energy demand, an increase has been recorded in all energy forms except natural gas, whose consumption showed stagnation. This is due to lower consumption in the energy transformation sector and a significant 9.2 percent increase in its final energy demand. A continuous increase in electricity consumption - which reached 4.8 percent in the observed period - is worth nothing. Energy forms which recorded highest consumption increase levels in 2003 are coal (16 percent) and diesel fuel (15 percent). In contrast to the fast increase in

  1. Energy modeling: nuclear energy as China's main energy after 2040

    International Nuclear Information System (INIS)

    According to the energy modeling and the strategic forecast of China's economic development and population, the energy demand in China in the coming century has been calculated yearly by computer simulation. It is shown by the calculation results that the primary energy consumption in 2050 will be 3.37-4.25 times as that of 2000. The fossil energy will still be the main energy during the early stage of 21st century, but it will be cut down rapidly since 2020s as its annual consumption is increased to 1.656-2.044 x 109 tce/a. Because the fossil fuel ressources in China are limited, more and more fossil fuel will be mainly turned to chemical products, and the environmental pollution will be serious if we still use the fossil as a main fuel widely. The amount of renewable energy will be increasing, but its share in the primary energy consumption will be cut down from 36% to about 20% during the first half of next century and then will maintain this portion. In this case, the nuclear energy will be developed rapidly during the early stage of next century and will become the main energy since 2040. The methodology of energy forecast has also been reviewed

  2. Energy consumption: energy consumption in mainland Norway

    Energy Technology Data Exchange (ETDEWEB)

    Magnussen, Inger Helene; Killingland, Magnus; Spilde, Dag

    2012-07-25

    The purpose of this report is to describe trends in energy consumption in mainland Norway, with an emphasis on key trends within the largest consumer groups. We also explain common terms and concepts in the field of energy consumption. Finally, we look at forecasts for future energy consumption, produced by bodies outside NVE. Total final energy consumption in mainland Norway in 2009 was 207 TWh. The most important end-user groups are households, service industries, manufacturing industry and transport. In addition, the energy sector in mainland Norway consumed 15 TWh. Energy consumed in the energy sector is not considered as final consumption, as the energy is used to produce new energy products. The long-term trend in energy consumption in mainland Norway is that fuel in the transport sector and electricity for the energy sector increases, while energy consumption in other sectors flattens out. The main reason for an increased use of fuel in the transport sector is the rise in the number of motorised machinery and vehicles in mainland Norway. This has caused a rise in gasoline and diesel consumption of 75 per cent since 1976. The petroleum sector is the largest consumer of energy within the energy sector in mainland Norway, and electricity from onshore to platforms in the North Sea and to new shore side installations has led to a rise in electricity consumption from 1 TWh in 1995 to 5 TWh in 2009. The energy consumption in households showed flat trend from 1996 to 2009, after many years of growth. The main reasons are a warmer climate, higher energy prices, the use of heats pumps and more energy-efficient buildings. In the service industries, the growth in energy consumptions has slightly decreased since the late 1990s, for much the same reasons as for households. In manufacturing industries the energy consumption have flatten out mainly due to the closure of energy-intensive businesses and the establishment of new more energy-efficient businesses. Electricity is

  20. Securing energy equity

    International Nuclear Information System (INIS)

    Addressing energy poverty rather than energy equity conveniently evades the problem of the gap in energy consumption per capita in the developed and developing world. For energy security policies to adequately address energy poverty it requires a widening of scope from national to global. This is a comment to the forthcoming presentation of IEA's proposition for a new architecture for financing universal modern energy access to be presented at the conference 'Energy for all-Financing access for the poor' held in Oslo in October 2011. - Highlights: → Addressing energy poverty may elude the disparity in energy consumption between rich and poor. → A minimum threshold of energy for the poor does not itself address inequity in energy consumption. → Energy equity may be secured by widening scope from national to global, from the poorest to us all.

However, we derive a `quasilocal dominant energy condition' which is the natural consequence of the local dominant energy condition. We discuss some implications of this quasilocal energy condition. In particular, we find that it implies a `quasilocal weak energy condition'.

    The world is facing significant growth in energy demand over the next several decades. Strategic in meeting this demand are the world-class energy resources concentrated along the Rocky Mountains and northern plains in Canada and the U.S., informally referred to as the Western Energy Corridor (WEC). The fossil energy resources in this region are rivaled only in a very few places in the world, and the proven uranium reserves are among the world's largest. Also concentrated in this region are renewable resources contributing to wind power, hydro power, bioenergy, geothermal energy, and solar energy. Substantial existing and planned energy infrastructure, including refineries, pipelines, electrical transmission lines, and rail lines provide access to these resources.

  18. Alternative Energy Development and China's Energy Future

    Energy Technology Data Exchange (ETDEWEB)

    Zheng, Nina; Fridley, David

    2011-06-15

    In addition to promoting energy efficiency, China has actively pursued alternative energy development as a strategy to reduce its energy demand and carbon emissions. One area of particular focus has been to raise the share of alternative energy in China’s rapidly growing electricity generation with a 2020 target of 15% share of total primary energy. Over the last ten years, China has established several major renewable energy regulations along with programs and subsidies to encourage the growth of non-fossil alternative energy including solar, wind, nuclear, hydro, geothermal and biomass power as well as biofuels and coal alternatives. This study thus seeks to examine China’s alternative energy in terms of what has and will continue to drive alternative energy development in China as well as analyze in depth the growth potential and challenges facing each specific technology. This study found that despite recent policies enabling extraordinary capacity and investment growth, alternative energy technologies face constraints and barriers to growth. For relatively new technologies that have not achieved commercialization such as concentrated solar thermal, geothermal and biomass power, China faces technological limitations to expanding the scale of installed capacity. While some alternative technologies such as hydropower and coal alternatives have been slowed by uneven and often changing market and policy support, others such as wind and solar PV have encountered physical and institutional barriers to grid integration. Lastly, all alternative energy technologies face constraints in human resources and raw material resources including land and water, with some facing supply limitations in critical elements such as uranium for nuclear, neodymium for wind and rare earth metals for advanced solar PV. In light of China’s potential for and barriers to growth, the resource and energy requirement for alternative energy technologies were modeled and scenario analysis

    International Nuclear Information System (INIS)

    Report presents the latest information on relations and trends in the Croatian energy sector. The reports gives a familiar overview of comprehensive data about and representative features of the Croatian energy sector, related to the supply and demand of energy at all levels. It produces a detailed analysis of energy trends and provides extensive data on capacity, reserves and prices as well as balances of individual energy sources - crude oil, petroleum products, natural gas, electricity, heat, coal and renewable source of energy. Basic economic and financial indicators, emissions of air pollutants and basic energy efficiency indicators for Croatia are also presented. In 2005, total primary energy supply in Croatia decreased slightly by 0.1 per cent with respect to the previous year. At the same time, GDP rose by 4.3 per cent, resulting in a drop in energy intensity of the total primary energy supply of 4.2 per cent. The energy intensity in Croatia was 20.1 per cent higher than the average energy intensity in the European Union, but a positive decreasing trend was noted during the past period. In 2005 the total primary energy production in Croatia fell by 3.5 per cent with respect to the previous year. The highest decrease was recorded in harnessing hydro power, and the production of crude oil and fuel wood also declined. Only the production of natural gas showed a growth of 3.5 per cent. Due to the decrease in the primary energy production, energy self-supply was also reduced to 47.9 per cent. A less value was achieved only in the year 2003. A continuing trend towards a gradual decline in energy self-supply was present throughout the past several years. Final energy demand increased by 3 per cent while demands in other sectors decreased. Energy transformation losses were reduced by 7 per cent, non-energy use declined by 5.6 per cent and energy transmission and distribution losses by 5.5 per cent, and there was a slight drop of 0.2 per cent in demand in energy

  20. Three dimensional energy profile:

    International Nuclear Information System (INIS)

    The provision of adequate, reliable, and affordable energy has been considered as a cornerstone of development. More than one-third of the world's population has a very limited access to modern energy services and suffers from its various negative consequences. Researchers have been exploring various dimensions of household energy use in order to design strategies to provide secure access to modern energy services. However, despite more than three decades of effort, our understanding of household energy use patterns is very limited, particularly in the context of rural regions of the developing world. Through this paper, the past and the current trends in the field of energy analysis are investigated. The literature on rural energy and energy transition in developing world has been explored and the factors affecting households' decisions on energy use are listed. The and the factors affecting households' decisions on energy use are listed. The gaps identified in the literature on rural household energy analysis provide a basis for developing an alternative model that can create a more realistic view of household energy use. The three dimensional energy profile is presented as a new conceptual model for assessment of household energy use. This framework acts as a basis for building new theoretical and empirical models of rural household energy use. - Highlights: ► Reviews literature on household energy, energy transitions and decision-making in developing countries. ► Identifies gaps in rural household energy analysis and develops a new conceptual framework. ► The 3-d energy profile provides a holistic view of household energy system characteristics. ► Illustrates the use of the framework for understanding household energy transitions.

    International Nuclear Information System (INIS)

    Speaking from the platform of the XIIIth annual session of the International Atomic Energy Agency, at New Delhi, AEC managing director Michel Pecqueur made a solemn appeal to the world community for the decisions which are needed on energy. The present energy crisis can lead the world to a recession and be a factor in grave troubles for peace and balance in the world. The crisis cannot be resolved without accrued recourse to the use of nuclear energy. Two essential themes were outlined: the development of nuclear energy in the world, and the increased reduction of proliferation risks. In concluding, he expressed the hop that with a greater effort in information media, the nuclear fact-of-life would be better accepted by the general public in future, for it is there that lies a brake which may hinder nuclear energy development

For instance, the market of oil -- which is the largest traded commodity worldwide -- needs to be closely monitored in order for all market players to know at any time what is produced, traded, stocked and consumed and by whom. In view of the role and importance of energy in world development, one would expect that basic energy information to be readily available and reliable. This is not always the case and one can even observe a decline in the quality, coverage and timeliness of energy statistics over the last few years.

  15. Energy efficiency and energy management: an abundance

    International Nuclear Information System (INIS)

    As France has just published a decree on the energy audit for large companies, and has thus been among the first countries to comply with an article of the European directive on energy efficiency, a set of articles discusses various aspects of these issues of energy efficiency and energy management. A first one presents this mandatory energy audit as a tool for a better energy efficiency, and illustrates the relationship between this commitment and the ISO 50001 standard for French large companies. A second article outlines the tools and standards of application of this energy audit in different legal texts. A third one comments the introduction of four new European arrangements on the labelling of products (indication of energy performance by retailers, objective of reduction of energy consumption, information displayed on site and on-line for various household appliances, current legislation). The next article comments the new German legislation on renewable energies which implements environmental requirements higher than European objectives, and tries to boost the carbon market. The presence of the ISO 50001 certification in the German law is also briefly addressed. Then, an article proposes an overview of a bill project, opinions of experts, and way to go for the new arrangement for energy saving certificates (CEE, certificat d'economie d'energie) launched by the French ministry of Ecology, and which aims at a 700 TWh saving. The content of each article of the bill project is presented and explained, and the relationship between certificate application and some standards is highlighted. The last article comments the decision of the European Court of Justice on the compatibility of Flemish Green Certificates with the European law

  19. Energy programs/energy markets: overview

    Energy Technology Data Exchange (ETDEWEB)

    1980-07-01

    This volume contains the technical details of the forecasting work of the energy policy study conducted during 1979 and 1980 by the Office of Applied Analysis, Energy Information Administration. A companion volume, Energy Programs/Energy Markets: Overview (DOE/EIA--0201/16), contains a description of the study, its background, and results. The first three chapters of this volume deal with the major energy supply markets; oil and gas, coal, and electricity. In each of these chapters, the focus is first on the effects of those Federal programs that are aimed primarily at the market for that particular fuel. Next, the discussion centers on the effects in that market (i.e., oil and gas, coal, and electricity) of Federal programs directed primarily at other energy markets. The consumer side of the energy market is discussed in Chapter 4. This chapter contains the analysis of various demand-management programs that attempt to encourage conservation. Chapter 5 describes a set of Federal programs that are designed to stimulate new suppy technologies, whereas Chapter 6 analyzes one particular trade-off opportunity in the energy-environment interface. A list of acronyms, glossary, and a complete index are included. This report is Volume 17 of the Energy Policy Study series. 11 figures, 37 tables.

  20. Energy conservation. Federal shared energy savings contracting

    International Nuclear Information System (INIS)

    A number of impediments have discouraged federal agencies from using shared energy savings contracts. As of November 30, 1988, only two federal agencies - the U.S. Postal Service (USPS) and the Department of the Army -had awarded such contracts even though they can yield significant energy and cost savings. The three major impediments we identified were uncertainty about the applicability of a particular procurement policy and practice, lack of management incentives, and difficulty in measuring energy and cost savings. To address the first impediment, the Department of Energy (DOE) developed a manual on shared energy savings contracting. The second impediment was addressed when the 100th Congress authorized incentives for federal agencies to enter into shared savings contracts. DOE addressed the third impediment by developing a methodology for calculating energy consumption and cost savings. However, because of differing methodological preferences, this issue will need to be addressed on a contract-by-contract basis. Some state governments and private sector firms are using performance contracts to reduce energy costs in their buildings and facilities. We were able to identify six states that were using performance contracts. Five have established programs, and all six states have projects under contract. The seven energy service companies we contacted indicated interest in federal shared energy savings contracting
