E.ON has inaugurated commercial operations at its Power-to-Gas (P2G) facility in Falkenhagen, Germany. (Earlier post.) The plant uses wind power and Hydrogenics’ electrolysis equipment to transform water into hydrogen, which is then injected into the existing regional natural gas transmission system.
The hydrogen, as part of the natural gas mix, can be used in a variety of applications including space heating, industrial processes, mobility, and power generation. The facility, which has a capacity of two megawatts, produces 360 cubic meters of hydrogen per hour.
This project makes E.ON one of the first companies to demonstrate that surplus energy can be stored in the gas pipeline system in order to help balance supply against demand. This method of energy storage is considered a key technology for the transformation of Germany’s energy system. It will reduce the need to take wind turbines offline when the local grid is congested and will therefore enable us to harness more wind power.—Dr. Ingo Luge, CEO of E.ON Deutschland
Swissgas, which represents more than 100 local natural gas utilities, is a partner in the project with a 20% capital stake and an agreement to purchase a portion of the gas produced.

For Hydrogenics Corporation, this has been a turnkey Power-to-Gas project which included supply, installation, connection and commissioning of the hydrogen production facility including gas compression, master controls, as well as a 5-year service and maintenance agreement.
