Shell and ITM Power will build the hydrogen electrolysis plant at Rhineland refinery, Germany. With a peak capacity of 10 megawatts the hydrogen will be used for the processing and upgrading of products at the refinery's Wesseling site as well as testing the technology and exploring application in other sectors. Currently the Rheinland refinery, Germany's largest, requires approximately 180,000 tons of hydrogen annually, which is produced by steam reforming from natural gas. The new facility will be able to produce an additional 1,300 tonnes of hydrogen per year, which can be fully integrated into the refinery processes, such as for the desulphurization of conventional fuels.
