in novouralsk, for the first time in russia, an installation for large-scale production of such hydrogen was invented in the twenty-first year. we made it and carried out factory tests. that is all characteristics. we have confirmed. we have confirmed the performance nominal five normal cubic meters. now hydrogen energy consumption. this is one of the key indicators. in the process of electrolysis, water under the influence of a direct electric current decomposes into oxygen and hydrogen. the technology is energy-intensive and expensive, the production of blue hydrogen costs about $ 2 per 1 kg, on the contrary, hydrogen obtained by electrolysis is expensive, they plan to solve the problem of profitability using excess electricity produced at large-tonnage nuclear power plants electrolyzers from novouralsk. they will be sent to the kola nuclear power plant, where the first experimental hydrogen production complex will be built, they are planned to be used to produce hydrogen specifically for sale, as a marketable product it is planned, while at the moment four such plants will be delivere
