Name of the project: Power to Gas for Hamburg

Description: The power-to-gas technology offers an innovative method for storing excess energy from renewable sources – including wind and solar energy – with which long-term fluctuations in energy production can be offset.

The Hamburg project features the development of an efficient PEM (proton exchange membrane) electrolyser in the 1 MW category. The space requirement for the stack (cell stack) of the new PEM unit is reduced by one-thirtieth compared to alkaline electrolysers. PEM technology shows a better performance dynamic for this and allows for a temporary overload mode of operation. Compared to conventional technology, the constructed system therefore makes its mark in terms of compatibility and performance – both beneficial for power-to-gas applications.

The resulting hydrogen is fed into the natural gas network and can then be used, saved, or converted back into electricity. The project has started at the end of 2012.

The project partners include: E.ON, NOW GmbH, Projektträger Jülich, Hydrogenics GmbH, SolviCore GmbH, Deutsche Zentrum für Luft- und Raumfahrt e. V., Fraunhofer-Institut für Solare Energiesysteme

Funding: The project is co-funded by NOW.
