Power-to-Gas Hydrogen: Techno-economic Assessment of Processes Towards a Multi-purpose Energy Carrier


The present work investigates Power-to-Gas (PtG) options for variable Renewable Electricity storage into hydrogen through low temperature (alkaline and PEM) and high-temperature (SOEC) water electrolysis technologies. The study provides the assessment of the cost of the final product when hydrogen is employed for mobility (on-site refueling stations), electricity generation (by fuel cells in Power-to-Power systems) and grid injection in the natural gas network. Costs estimations are performed for 2013-2030 scenarios. A case study on the impact of variable Renewable Electricity storage by hydrogen generation on the Italian electricity and mobility sectors is presented.
