PRODUCTION OF SYNTHETIC NATURAL GAS FROM CARBON DIOXIDE AND RENEWABLY GENERATED HYDROGEN: A TECHNO-ECONOMIC ANALYSIS OF A POWER-TO-GAS STRATEGY  

Payne Fellow Robert Braun writes about how power-to-gas to energy systems are of increasing interest for low carbon fuels production and as a low-cost grid-balancing solution for renewables penetration. However, such gas generation systems are typically focused on hydrogen production, which has compatibility issues with the existing natural gas pipeline infrastructures. This study presents a power-to-synthetic natural gas (SNG) plant design and a techno-economic analysis of its performance for producing SNG by reacting renewably generated hydrogen from low temperature electrolysis with captured carbon dioxide.
