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) While the current facility feeds pure hydrogen (“WindGas”) directly into the gas grid, the new methanation plant provides for the generation of “green” methane.

Audi opens power-to-gas facility in Werlte/Emsland; e-gas from water, green electricity and CO2

Green Car Congress

Audi’s e-gas plant. Audi has opened its e-gas plant in Werlte, making it the first automobile manufacturer to develop a chain of sustainable energy carriers. The Audi e-gas plant, which can convert 6MW of input power, utilizes renewable electricity for electrolysis to produce oxygen and hydrogen. Components of the e-gas plant.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

Andrews have demonstrated that ammonia can be synthesized directly from air (instead of N 2 ) and H 2 O (instead of H 2 ) under a mild condition (room temperature, one atmosphere) with supplied electricity which can be obtained from renewable resources such as solar, wind or marine. tons of CO 2 is released per ton of ammonia produced.

Duke study finds China’s synthetic natural gas plants will have heavy environmental toll; 2x vehicle GHG if used for fuel

Green Car Congress

Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature Climate Change.

Audi e-gas plant qualified to participate in balancing market to stabilize grid

Green Car Congress

The Audi e-gas plant in the city of Werlte in Lower Saxony ( earlier post ) produces CO 2 neutral-fuel (synthetic methane from water, renewable electricity and CO 2 ); it now also contributes toward stabilizing the public power grid. This therefore considerably increases the overall efficiency of the Power-to-Gas/biogas plant.

Hydrogenics wins order from E.ON for power-to-hydrogen-gas energy storage project in Germany

Green Car Congress

for a “Power-to-Gas” project in Germany. The 2 MW energy storage facility, to be located in Falkenhagen in northeast Germany, will use surplus renewable energy sources to produce hydrogen for storage in the country’s existing natural gas pipeline network. Electrolysis company Hydrogenics Corporation has received an order from E.ON
