Jupiter 1000, the first Power to gas project in France

Jupiter 1000, the first demonstrator in France to recover surplus electricity from renewable sources and recycle CO2.

At Le Bourget, within the framework of COP21, GRTgaz and its industrial partners officially announced the launch of the first Power to Gas project linked to the French gas transmission network, called Jupiter 1000. The demonstrator project, based in the industrial and port sector of Fos-sur-Mer (13 - Bouches du Rhône département), provides an innovative, efficient solution to recover surplus electricity from renewable sources and recycle CO2. Seven French partners with complementary skills - Atmostat, the CEA, CNR, Leroux and Lotz Technologies, McPhy Energy, TIGF and the Grand Port Maritime of Marseille - have joined forces with GRTgaz to build the first demonstrator, which is due to come into service in 2018.

The massive development of intermittent renewable energy sources, launched to reach the energy transition targets, creates major issues in terms of balancing and storage of surplus generation on the electricity network. The Power to Gas technology provides an innovative solution by transforming surplus supplies of electricity from wind and solar sources into synthesized gas; a carbon-neutral gas that can be injected in full into the natural gas network.

The Power to Gas process uses the electricity to transform water into hydrogen via electrolysis. The hydrogen can then be combined with carbon dioxide (CO2) to obtain synthesized methane, via methanation. This operation is all the more useful in that it enables capture and recycling of CO2 from factory smoke emissions. The hydrogen or synthesized methane thus produced can then be injected in the transmission network.

Although there are already twenty or so demonstrators in use in Europe, mainly in Germany, the Jupiter 1000 project, with a power rating of 1 MWe, is the first installation at this production scale in France. Green hydrogen will be produced using two electrolyzers involving different technologies, from 100% renewable energy. The demonstrator will be based on an innovative methanation technology. The CO2 necessary will be captured on a nearby industrial site. In the light of the performance levels shown by the demonstrator, GRTgaz and its partners will work on the future technical and economic standards of a full-sized installation of this type. Over the longer term, the idea is to launch the Power to Gas activity in France. More than 15 TWh of gas per year could well be produced using the Power to Gas system by 2050.

The project cost stands at €30 M, almost two-thirds of which are shouldered by the industrial partners and one-third financed in the form of grants by the European Union (ERDF), the French State (investments in the future, entrusted to the ADEME) and the Provence-Alpes-Côte d’Azur Region of France.
