Storage of Renewable Energy in Hydrogen Using Power-to-Gas Technology

DMITRY DUNIKOV

Abstract


In Kamchatka region up to 30% of electricity is produced from renewables, to avoid curtailment by the grid operator the excess power should be used for hydrogen production by water electrolysis. For each 1% of saved geothermal steam 92 t of H2 can be annually produced. Blending the produced hydrogen with natural gas is a promising option due to the availability of existing infrastructure. The H2/CH4 mixture suits for commercial and domestic use, hydrogen as well can be separated from the mixture and used in fuel cells.
