Power-to-Gas (P2G), a flexibility tool to accompany the transformation of the energy system

Power-to-Gas (P2G) is one of the envisaged solutions to the problem of production intermittency of renewable energies, of energy storage and peak consumption management. This Power Point presentation proposes a rather detailed overview of the possibilities and perspectives of this technology. It addresses the context and stakes of P2G: challenges related to the transformation of the energy system, implemented technologies. Different technologies are presented with their drawbacks and benefits, their main actors, their maturity level: electrolysis (alkaline, proton exchange membrane, solid oxide electrolysis), methanation (chemical, biological, CO₂ capture). It proposes a presentation of the various actors in European countries: energy industries, P2G component providers and experts, research organisations, public bodies and associations, political field. P2G European projects are then presented: studies, R and D projects, demonstrators. The last part proposes an overview of the regulatory, environmental, safety and acceptability issues
