Introduction Analysis of world-wide trends to windpower engineering development makes it possible to conclude that this ecologically clean and renewable type of power engineering will become one of the key sources for satisfaction of energy needs of the world community in the immediate future. In spite of all windpower engineering intriguing capabilities one cannot but emphasize a drawback peculiar to it in connection with irregularity of power produced and so makes it necessary to search for rational technologies providing power production in periods of time when wind load is not available. To solve this problem, it is necessary to build up a system, which provides energy storage with following consumption. The wind-hydrogen plant (WHP) is one of possible variants of such system. The concept of WHP based on two basic directions of use of hydrogen as energy carrier in power engineering: 1. Energy accumulation in independent uninterrupted power supply systems. 2. Increase of economic efficiency of power stations by accumulation of superfluous energy in hydrogen and use of this energy at o'clock "peak" and emergencies. According to it within the framework of the STCU project Uzb-23j we develop: 1. Energy-technological complex (ETC) of moderate power (200-250 kW) independent use for the areas removed from industrial networks, providing uninterrupted power supply of consumers in areas with sufficient wind potential. 2. ETC of high power (500-600 kW) universal use for accumulation of superfluous energy in hydrogen and use of this energy according to schedules of consumption. Let us note that similar complexes are developing by the Norwegian experts for power supply of the manned islands removed from centralized networks. Creation of such complex on island Utsira, that will provide with the electric power only due to use of no conventional renewed sources of primary energy is offered. The scientific and technical preconditions created by State Design Office "YUZHNOYE” and Institute of Mechanical Engineering Problem of the National Academy of Science of Ukraine at performance of conversion works in area of wind- hydrogen power engineering are put in a basis of our development. © 2004 Kluwer Academic Publishers.
