The project of creating an experimental plant for the production of hydrogen by electrolysis of water and with an internal cycle of energy. (project announcement) The project provides for the development of an integrated technology with the creation of an experimental plant for the production of cheap hydrogen in an environmentally friendly way. This technology provides for the production of hydrogen by electrolysis, but at the expense of the internal energy of this process. Internal energy means the energy released from the process of spontaneous ionization of oxygen, which is released from water simultaneously with hydrogen. In conventional electrolysers, oxygen is vented to the atmosphere, and in the proposed project it is used to generate energy. That is, this power generation mechanism is an energy system built into the structure of a hydrogen production plant that uses oxygen generated by an electrolyzer to generate power. And this energy is spent on the operation o
