Towards a new perspective on the efficiency of water electrolysis with anion- conducting matrix

Abstract

Achieving carbon neutrality in the future involves the use of low-carbon hydrogen as an energy source - in the power industry and heat supply of isolated areas - as a carbon-neutral fuel for generation and a secondary source of energy. In the transport sector, the prospects for the use of hydrogen extend to almost all types of vehicles - from cars, trains and ships to special-purpose equipment, air transport, both in fuel cells and in internal combustion engines.Rosatom State Corporation has developed a technology for producing hydrogen by water electrolysis using an anion-conducting matrix. The matrix is an inorganic fibrous material, and anionic conductivity is achieved as a result of the introduction of potassium cations during impregnation with a KOH solution. A wide range of productivity up to 115 % and the possibility of its dynamic change make it possible to effectively combine these electrolyzers with renewable energy sources.
