German power-to-gas facility opens green methanation plant; €28M STORE&GO project

Green Car Congress

A methanation plant expansion to the existing power-to-gas (PtG) facility in Falkenhagen, Germany has officially opened as part of the international €28-million (US$33.5-million) million) STORE&GO research project. Moreover, it provides for unrestricted use of the natural gas infrastructure, including for transport and storage.

E.ON developing pilot hydrogen plant for storing wind power in the German gas grid

Green Car Congress

is developing a pilot plant in Falkenhagen in the north east of Germany to convert power from wind energy into hydrogen which can then be stored in the country’s gas grid. Using power from renewable energy sources, the plant will produce about 360 m 3 (30 kg) of hydrogen per hour from 2013 onwards through electrolysis.

Power-to-Gas project awarded DECC grant funding

Green Car Congress

One of the projects to be awarded grant funding is the “P2G BioMet” project, led by Hydrogenics, along with consortium members CNG Services, Electrochaea and National Grid. The Power-to-Gas via Biological Methanation system uses surplus renewable electricity to split apart water (electrolysis), releasing hydrogen and oxygen.
