Energiepark Pirmasens-Winzeln

Aim of the power-to-gas process:
Surplus wind or solar power is to be converted into renewable methane, which is then stored in the natural gas network and then transformed into energy or heat again in accordance with demand.

How it works Power-to-gas plant Pirmasens- Winzeln:

Biomethane is generated by means of supplied hydrogen in a reaction with carbon dioxide. Particularly at the pilot plant in Pirmasens, special, methane-forming microorganisms are used in this process. These use the CO2 of the biogas, which comes from the own biogas plant to form further Methangas in two 25m high columns next to the biogas plant. The almost pure methane gas produced in this way has been fed into the gas network since September 2016.
Thus, the plant, which is unique in its configuration throughout Germany, is to supply up to 440,000 m3 of gas annually into the gas network.

Future expansion plans:

Expansion around an electrolyzer to ensure proper supply of hydrogen but also to increase Efficiency.

Other Advantages from our unique process:

•  The countercurrent principle under elevated pressure improves the
  mass transfer from the gas phase to the liquid phase. Therefore,
  higher specific sales rates.
• The printing operation permits an extremely flexible driving of the reactor columns. Thus, the reactors can be operated discontinuously, semicontinuously and continuously.
• A variable volume fraction of the fermenters can be used as intermediate storage for the product gas.
