Converting wind power for storage purposes
PEM electrolysers in the megawatt range are being used at Energiepark Mainz for the first time. This process can adapt well to electricity fluctuations. © Siemens, Erich Malter
Power-to-Gas plant at Energiepark Mainz with positive interim results
Systems based on polymer electrolyte membranes (PEM) are used in the electrolytic production of hydrogen at Energiepark Mainz. In the research phase, systems with peak loads of up to 2 MW were used for the first time. At the beginning of the project, the typical output of PEM electrolysers was around 100 kW.
The advantages of this membrane electrolysis method are that the hydrogen involved is very pure, the process requires little maintenance and it can react well to fluctuations in the power grid. In Mainz, the gas is compressed with ionic compressors, stored and fed into the natural gas network or delivered to hydrogen filling stations and industrial plants.
Hydrogen is a versatile chemical energy storage medium and base material. Up to 10 % hydrogen can be added to natural gas, and it can be used directly in industrial production processes while being easy to store.
The electrolysis plant generates up to 1,000 Nm³ of hydrogen per hour, which is fed into the natural gas network for the Mainz-Ebersheim district. The energy park completed the research phase in 2017 and has started normal commercial operation.
