With Power-to-Gas (PtG) technologies, sustainable electricity can be converted into gas and then stored in the existing gas infrastructure, transported and provided as needed – independent of the natural volatility of wind and solar energy. Forecasts up to 2050 indicate that comprehensive and effective climate protection is not possible without PtG. The “Deutscher Verein des Gas- und Wasserfaches” (German Association of the Gas and Water Sector – DVGW), an independent technical-scientific network for all questions related to gas and water supply, has published an updated map giving an overview of all PtG projects in Germany, including both completed and planned facilities.
The DGWV map shows that the number of PtG plants in Germany as well as their installed capacity is constantly increasing compared to previous statistics. 35 PtG plants are currently in operation with a total capacity of around 30MW. However, most of them are pilot or demonstration projects on a small scale and serve research purposes. Industrial-scale plants are still the exception, also for the 16 projects in planning.
Nevertheless, total PtG capacity will increase significantly in the future (estimated at 273MW), mainly due to two 100MW projects being implemented by two TSCNET shareholders: Amprion, one the four German transmission system operators (TSOs), and the Dutch-German TSO TenneT are pursuing the two most powerful sector coupling projects currently underway in Germany: “hybridge” and “ELEMENT ONE” which are planned at two different sites in the German federal state of Lower Saxony. According to current planning, “ELEMENT ONE” will be gradually operational by 2022 and “hybridge” will be fully operational by 2023.
