A study was made for the purpose of electrification of unelectrified zones of the mountainous areas in developing countries using extremely small hydroelectric power facilities. The target for this project is a development of a micro hydroelectric power system with a size of about 5kW, which is estimated regarding that 1 village has 80 houses and each house needs electricity of 60W. In the study, the low-head system using a weir of irrigation channels in Subang pref. of West Java state was selected by the evaluation of access, stability of flow rate, natural conditions, etc. The hydroelectric power plant is of a flow-in method in which water is taken from the left bank and is injected/discharged to the downstream of the left bank. As the hybrid complementary power source, hybrid battery with a two-hour charging time at peak and a capacity of 3.5kWh was considered. When estimating the construction cost of the hybrid micro hydroelectric power system and equalizing by durable years, the ...

At COP3 in 1997, an agreement was made to the innovative technical development/promotion by international cooperation, and the promotion of transfer of environmental technology to developing countries. Under the agreement, a feasibility study of international cooperation was made, and especially a study was conducted of the utilization/development of solar energy by the innovative solar thermochemical process. The main reason for global warming is emissions of a large amount of CO2 caused by the direct combustion of fossil fuels. Therefore, a CO2 recycle system taken up in the study enables a more substantial decline in CO2 emission (kg/kWh) per unit generation than the conventional thermal power system by composing solar methanol or solar dimethyl ether using fossil fuels including coal, water, CO2, etc. as raw materials and using solar energy as heat source, and by using this as fuel (solar fuel). CO2 can be reduced by 13% to 14% by substituting solar methanol or solar dimethyl ether ...
