Power-to-gas systems may be deployed as adjuncts to wind parks or solar power plants. The excess power or off-peak power generated by wind generators or solar arrays may then be used hours, days, or months later to produce electrical power for the electrical grid. In the case of Germany, before switching to natural gas, the gas networks were operated using towngas, which for 50–60 % consisted of hydrogen. The storage capacity of the German natural gas network is …

How to store energy? Power-to-gas! | Don''t Waste My Energy!
First of all, power-to-gas aims to store the renewable energy and not to produce energy. The research is based on the expectation that the renewable energy will be the only, or the largest energy source. The solar energy will probably be the most beneficial. Thus, it gains more energy in summer and less in winter.
