Power to Gas:<br />
methanation of hydrogen<br />
The intermittent character of sustainable energy technologies, such as solar and wind<br />
energy, affects the stability of the existing electricity infrastructure. As the installed capacity<br />
of intermittent energy sources increases, the need for flexibility in electricity accommodation<br />
and storage also increases. Interest has been expressed in the possible ways to use the gas<br />
infrastructure for electricity storage, in which Europe’s extended gas infrastructure would<br />
enable seasonal storage of electricity by the conversion of electricity into gas.<br />
<strong>DNV</strong> KEMA acknowledges the value of the gas infrastructure to store excess electricity in<br />
times of high production and low demand. By conversion of electricity into hydrogen (by<br />
electrolysis), and subsequently into methane (by methanation), large amounts of energy can<br />
be stored in the natural gas infrastructure. It enables electricity supply and demand<br />
matching, seasonal energy storage and the production of sustainable methane without<br />
dependence on biomass. It also enables CO 2<br />
recycling.
