The article analyzes the energy potential of alternative sources of Ukraine. Projects using hydrogen technologies aimed at attracting solar energy to the infrastructure of energy technological complexes, in particular water desalination systems and for refueling vehicles located in areas with high solar radiation potential, are considered. During the operation of water desalination plants using a solar power station (SES) as an energy source, contingencies are very likely to arise due to either a power outage (due to cloudy weather) or an emergency failure of individual elements of the system. In this case, it is required to ensure its decommissioning without loss of technological capabilities (operability). For this purpose, it is necessary to provide for the inclusion in the technological scheme of the energy technological complex of an additional element that ensures the operation of the unit for a given time, determined by the regulations for its operation. As such an element, a buffer system based on a hydrogen energy storage device is proposed. The current level of hydrogen technologies that are implemented in electrochemical plants developed at the Institute of Mechanical Engineering named after A. N. Podgorny National Academy of Sciences of Ukraine (IPMash NAS of Ukraine) allows the production and accumulation of hydrogen under high pressure, which eliminates the use of compressor technology. A schematic diagram of an autonomous solar-hydrogen energy-technological complex for refueling vehicles is given. The features of connecting solar panels as part of the energy technology complex are described. Ref. 20, tab. 1, fig. 6.
