ZSW completes 250-kilowatt research plant for storing green electricity. Baden-Württemberg’s Environment Minister Franz Untersteller: "The plant is a successful step in establishing the new technology."
A further hurdle en route to achieving the marketability of Power-to-Gas technology has been overcome: on 30 October 2012, the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research, ZSW) inaugurated a research plant with a connected electrical load of 250 kilowatts. The plant, which has been funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), converts green electricity into hydrogen and methane. With a possible methane production of up to 300 cubic metres per day, it is the largest plant of its kind worldwide and ten times more powerful than the test plant constructed at ZSW three years ago. The scientists from Stuttgart are therefore close to achieving the industrial application of the new electrical storage technology.
Together with their colleagues from the Fraunhofer IWES research institute and the SolarFuel company, the ZSW researchers want to continue optimising the technology during operation. That should make it easier to scale up Power-to-Gas plants into the 1-20 megawatt range relevant for the energy industry. The R&D work is also concerned with assessing future storage requirements.
