Solar Fuels and Power-to-Gas technologies
Until now electricity was generated by adjustable power stations depending on the demand. The increasing renewable electricity production depends on the weather to a high extend and therefor fluctuates strongly. Excess and shortage situations in the production of electricity from wind and sun require a broad mix of energy storage. Several technologies are currently under development. The conversion of green electricity to methan gas is particularly promising (Power-to-Gas, P2G). This way long-term storage of electricity becomes possible in high quantities and it can everywhere be provided through the existing infrastructure of the natural gas grid.
SolarFuel is the global first mover commercialising P2G technology. The German startup converts renewable energy to renewable methane (synthetic natural gas) by integrating electrolysis and methanation into one solution. Power to Gas is useful for storing and transporting huge amounts of energy and enables the coupling of the electricity and gas networks to create the smart green super grid. The motivation for developing the new P2G technology is driven by the volatility of wind and solar — the wind doesn’t always blow and the sun doesn’t always shine — and the resulting need for huge long-term energy storage. The potential storage capacity of Germany’s gas network could power the country for several months.
