The inauguration of the world’s first industrial-scale power-to-gas plant on 25 June in Werlte, Lower Saxony, represents not just a significant success for AUDI as the operator. The scientists and engineers at the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW) in Stuttgart also see this as confirmation of their work. This is because the impending commissioning of the 6 MW plant is a direct result of the many years spent researching, developing and demonstrating the power-to-gas process – known as P2G® – at ZSW. “The construction of the plant in Werlte marks a further step on route to industrialising P2G. The fact that a successful global corporation such as Audi is now banking on it provides testimony to our technology,” explains Dr Michael Specht from ZSW.
