The purpose of the article is to identify ways to reduce greenhouse gas emissions, which significantly contribute to the heat balance of the earth. The 2019 report on the gap in emission levels prepared by the United Nations Environment Program shows that measures on current policies to reduce harmful emissions are clearly inadequate. There is a constant growing interest in renewable energy in the world caused by environmental considerations: climate change and an increase in the content of greenhouse gases in the atmosphere. In Ukraine, the use of renewable energy sources, in particular wind and solar energy, is developing rapidly. At the same time, when introducing new capacities of renewable energy facilities, there are mains and system problems. Therefore, an increase in renewable energy capacities requires the creation of a more flexible energy system in Ukraine, including resolving the issue of reserve and balancing capacities. The article substantiates the use of power plants based on renewable energy sources, which are equipped with hydrogen-based electric energy storage systems, as balancing capacities of an energy storage system operator. The specified system of electric energy storage allows the transfer of energy from the period of its “surplus” to the period of its “deficit”. The peculiarity of the hydrogen technology is that it provides the most economical option for storing electricity and the further use of this stored energy with a discharge duration of up to several days. Information is provided on a real pilot project for introducing energy storage from renewable energy sources using hydrogen technology, which is being implemented in the European Union under the "Horizon 2020" program. RES hybrid plants that are equipped with hydrogen technology can provide real-time energy balancing. The technically achievable potential of renewable energy in the country exceeds the current annual electricity consumption of Ukraine. The use of "green" hydrogen, produced without CO2 emissions, contributes to solving the environmental problem of global warming. Ref. 9, tabl. 1, fig. 3.
