Power-to-gas

Power-to-gas (often abbreviated P2G) is a technology that uses electric power to produce a gaseous fuel.[1] When using surplus power from wind generation, the concept is sometimes called windgas.[citation needed]

Most P2G systems use electrolysis to produce hydrogen. The hydrogen can be used directly,[2] or further steps (known as two-stage P2G systems) may convert the hydrogen into syngas, methane,[3] or LPG.[4] Single-stage P2G systems to produce methane also exist, such as reversible solid oxide cell (rSOC) technology.[5]

The gas may be used as chemical feedstock, or converted back into electricity using conventional generators such as gas turbines.[6] Power-to-gas allows energy from electricity to be stored and transported in the form of compressed gas, often using existing infrastructure for long-term transport and storage of natural gas. P2G is often considered the most promising technology for seasonal renewable energy storage.[7][8]

Due to the intermittency of these sources, effective and inexpensive energy-conversion and storage technology is needed. Motivation for the possible electrolysis application of reversible solid-oxide cells (RSOCs), including a comparison of power-to-fuel/fuel-to-power to other energy-conversion and storage technologies is presented.
