Hydrogen production and hybrid use of alkali metals in technologies of energy production and storage of electric energy using ECG and GTU

Hydrogen is an effective energy carrier for thermal power technologies and electrochemical sources of electric current. The proposed technology eliminates the need for storing and transporting hydrogen and ensures its production in the volume required for direct use at power plants. This paper considers the possibility of using alkali metals as the most effective method for producing hydrogen by reaction with water. The reaction product (alkali) is repeatedly reduced to pure metal by electrolysis using energy (during the nighttime dip in energy consumption at thermal power plants and nuclear power plants) or using renewable energy during its natural availability (hydroelectric power plants, solar power plants, wind power plants). Calculation studies have shown that the process of water reduction by alkali metals is exothermic, with the release of heat of high thermodynamic potential, which allows, along with the direct conversion of hydrogen into electrical energy using fuel cells, to carry out additional production of electrical energy based on the thermodynamic Rankine or Brayton cycles.
