German utility E.ON (FWB: EOAN) has commenced building a pilot plant in Falkenhagen, Germany which will convert excess wind power into hydrogen power.

The plant’s existence means bottlenecks are avoided on the national grid as the surplus from wind farms is converted to hydrogen, in effect making the existing gas infrastructure a kind of hydrogen storage capability, reports the Hydrogen Journal.

 “If Germany expands the use of renewable energy sources in the coming years as planned, the power supply on very windy or sunny days will exceed demand more and more often, and to a growing extent,” said Klaus-Dieter Maubach, member of the E.ON AG Board of Management responsible for technology and innovation.

 “This will increasingly bring the power grid to the limits of its capacity.”

“E.ON is therefore investing in the development of technologies to store large energy volumes. In this respect, power-to-gas is a promising solution for the future energy supply system.”
