Achieving net zero carbon dioxide (CO2) emissions by 2050, as presented in the IPCC's special report on global warming at 1,5 °C, has prompted large-scale use of the new carbon-free energy carrier hydrogen to decarbonize the economy. The production of hydrogen using electrolysis units near the units of the existing nuclear power plants of Ukraine allows for the organization of large-scale production in the short term and can serve as a supplement to the production of hydrogen using renewable energy sources. On the basis of statistical data regarding the operation of NPP power units during 2018-2021, average annual coefficients of use of the installed capacity of power units were calculated and the optimal electrical power of the electrolysis plant was proposed. Taking into account the technological parameters of such an installation, namely, the consumption of electrical energy for the production of 1 kg of hydrogen at the level of 52 kW·h and the consumption of feed water in the amount of 22 liters, the total productivity of low-carbon hydrogen was obtained in the amount of 17417 kg per hour or 148 thousand tons per year. And taking into account the underutilization of existing nuclear power plants, the potential for low-carbon hydrogen production may reach from 444 thousand tons to 592 thousand tons per year in the short term.
