Hydrogen production, storage, and use at nuclear power plants

The present status of the problems of safe storage and use of hydrogen in the world hydrogen-energy sector are analyzed. Specific examples of foreign and domestic designs of atomic-commercial complexes based on operating nuclear power plants, viewed as hydrogen producers and users, are presented. A method of producing hydrogen accumulators with cartridges which contain microcapsules or capillaries, made of high-strength materials and filled with hydrogen under high presure (above 100 MPa), is proposed as a promising direction for solving storage and use problems. The mechanisms of introducing/extracting hydrogen into/from microelements in the space of the accumulators up to a working pressure of 0.2-1 MPa are based on diffusion and active thermomechanical principles.
