The purpose of the article is to analyze the water resources of Ukraine and find out the possibility of using them to obtain "green" hydrogen. Deployment of modern hydrogen technologies for the energy needs of Ukraine is becoming an important area. The use of hydrogen will provide significant benefits for Ukraine's energy system, environment and business. The potentially possible volume of "green" hydrogen production in Ukraine by electrolysis is calculated based on the results of scientific research on the potential of electricity generation by wind and solar plants. For the calculation of potential output "green" hydrogen via electrolysis provided specific power consumption of 4.5 kW ∙ h / n m3 H2. The potential annual production of "green" hydrogen in Ukraine is 505,132 million n m3 per year. Electrolysis of water is currently considered the most optimal technology for obtaining stable hydrogen. 1.5-2.0 l of water is used to produce 1 n m3 of H2, so 757.7 million m3 of water is required to use the annual potential of “green” hydrogen per year (505.132 million n m3). The projected reduction of water losses by 2030 due to the improvement of technological processes of lifting, production and transportation of water as a result of the introduction of energy efficient technologies, allows to meet 70% of water demand to use all available average annual production potential of "green" hydrogen per year (518 million m3). Analysis of stocks of normatively treated and normatively pure without wastewater treatment (4473 млн м3) showed a 6-fold excess of water demand for the realization of the full potential of "green" hydrogen. Seawater can also be used to produce hydrogen. Thus, the available water resources of Ukraine are quite sufficient to fully realize the potential of green hydrogen production without increasing the water intake. Ref. 18, table 1, fig. 5.
