RWE officially started operting its power-to-gas system in Ibbenbüren in North Rhine-Westphalia on Monday. This is the first time a system solution is being implemented for the efficient combination of local electricity, natural gas and district heating supply.
Excess electricity produced by renewable sources will be converted via electrolysis into hydrogen gas, which will then be methanised and fed into the natural gas grid. The gas can thereafter be used again at a later point of time for electricity production in a co-generation plant. This plant has a electricity capacity of 150 kW and an efficiency of 86%.
The power-to-gas solution is seen as a long-term key technology for the future of energy supply, according to RWE. This solution makes it possible to respond immediately to fluctuations in power supply from PV and wind power plants.
Energy storage is hereby seen as an indispensable element of future electricity systems, according to the CEO of RWE Germany, Arndt Neuhaus, keeping in mind the 50% renewable energy target to be reached by 2030 in Germany.
