CO₂ methanation catalysts and their applications to energy storage and transport

Abstract

Supported metal catalysts for synthetic methane production by hydrogenation of CO₂ was reviewed. Some of recent researches and developments in applications of CO₂ methantation to efficient utilization of renewable energy resources were introduced as well. It was highlighted that CO₂ methanation was old but still played an important role in energy storage and transport, especially when renewable energy resources were concerned.
