During the 3-hour functioning test over the weekend in Falkenhagen, Germany, E.ON’s Power-to-Gas (P2G) unit produced 160 cubic meters of hydrogen for injection into the gas pipeline system. The start-up of the P2G unit “marks the first time E.ON has successfully implemented all stages of the process, from receiving electricity to injecting hydrogen,” the company said. The electricity to run the P2G unit is supplied by a nearby wind farm. The electricity runs electrolysis equipment that transforms water into hydrogen which is injected into the regional gas transmission system. The hydrogen hereby becomes part of the natural gas mix and can be used to generate electricity or heat at a later stage. The P2G unit at Falkenhagen is scheduled to “enter into full service” in late August, E.ON announced. Once operational on a commercial basis, it will use surplus electricity from renewable energy sources to produce about 360 cubic meters of hydrogen per hour.
