Fos-sur-Mer (13): « Jupiter 1000 », a Power to Gas demonstrator to put the

energy networks at the service of energy transition

#Cooperation #Renewable Energies #EnergyTransition

This week Thierry Trouvé, Chief Executive of GRTgaz, and Christine CABAU WOEHREL, General

Manager of the Port of Marseille Fos, laid the first stone of the Power to Gas demonstrator « Jupiter

1000 » in Fos-sur-Mer (Bouches-du-Rhône), in the presence of the Chairman of Ademe and the

project’s industrial partners.

The first Power-to-Gas project connected up to the French gas transport network christened « Jupiter 1000 », is being built in Fos-sur-Mer, at the « Innovex » business incubator located within the PIICTO platform. This demonstrator with a power of 1 MWe constitutes a novel industrial challenge in France. What it involves is experimenting the conversion of excess electrical energy of a renewable origin into green gas, either in the form of hydrogen, or in the form of synthetic methane (after capture and storage of CO2), subsequently injected into the transport network.

This project is also going to enable testing of the technical and economic viability of Power-to-Gas and the emergence of a new renewable gas production sector by 2030, the idea being to detect and solve all the technical, economic or regulatory difficulties and eventually reduce the investment and operating costs.

Coordinated by GRTgaz, this project is mobilizing a coalition of French partners with complementary skills: McPhy Energy for electrolysis, Atmostat and CEA for methanation, Leroux & Lotz for the capture of CO2, CEA for R&D, CNR supplying the renewable electricity and providing the future remote management of the facility, RTE for the processing of the electrical data and GRTgaz and TIGF managing the injection into the gas networks. GRTgaz is moreover providing the engineering and the overall integration, then eventually the operation of the site. The expertise of these players guarantees mastery of the technologies implemented for the project.

« Jupiter 1000 » is also being conducted in collaboration with the Great Seaport of Marseilles, and will enjoy financial aid from 3 sources: the State, under the Investments for the Future Programme entrusted to ADEME, the Provence-Alpes Côte d’Azur Region and the European Regional Development Fund (ERDF).

With the laying of the first stone, the partners are pleased to announce the passing of a major milestone in the advancement of the project: the start of the construction works for the facilities. It will nevertheless be necessary to await the construction of the buildings and the roads and also the connection to the gas and electricity networks before being able to install the electrolysis units at the end of 2018 and the methanation reactors at the beginning of 2019.

The works are already well advanced at the OEM’s who are partners of the project, as testified by the following videos:



Power-to-Gas is already a reality in Germany as illustrated by the Audi e-gas site in Werlte (Lower Saxony, Germany). Discover the report produced by Romain Pernot for Actu-Environnement.



Thierry Trouvé will speak at the European Energy Transition Conference, at the round table -

« The storage revolution, what are the potentials for the cities and regions ? », on Wednesday 31 January from 14.45 to 16.00.
