E.ON will invest €5m to develop a pilot plant in Falkenhagen, Germany, to convert power from wind energy into hydrogen for storage on the gas grid. The project will begin in 2013 and 360 metres of hydrogen per hour will be produced by electrolysis before being fed into the Ontras gas grid to be used like normal gas. E.ON is committed to intensively testing the technology which has huge potential. At present, up to 5 percent hydrogen can be added to the natural gas grid without any problems, and in the medium term experts expect up to 15 percent. This means that today’s entire renewable power output could be stored in the German gas grid.
