The Jupiter 1000 project, France's first Power to Gas demonstrator plant, was officially launched by ENGIE subsidiary GRTgaz on March 30. So what is the principle behind it? It is to convert energy generated from renewable sources to gas that can then be stored. Find out more...
Green energy sources like wind and solar power are, by their nature, intermittent. This means that the amount of energy they generate varies with the seasons. As a result, it is often difficult to balance supply with demand.
Power to Gas technology now offers a solution to the problem of storing surplus energy generated from renewable sources. Power to Gas technology consists of converting power generated from renewable sources into hydrogen by electrolysis of water, or into synthetic methane following a methanation stage that combines the hydrogen with CO2. Fully compatible with natural gas, these gases can then be injected into the natural gas supply network with no need for future treatment.
The Jupiter 1000 demonstrator is France's first Power to Gas project, and is expected to go live in 2018. With a generating capacity equivalent to 1 MW, it is directly connected to the natural gas supply network.
How does it work? Jupiter 1000 converts water into hydrogen by electrolysis using only surplus electricity generated from renewable sources. The resulting hydrogen is then combined with CO2 recycled from industrial fumes to produce methane. This completely carbon-neutral gas is then injected into the natural gas supply network.
Ultimately, the project will bring a new level of flexibility to the energy network, at the same time as encouraging the development of renewable energy facilities.
The Jupiter 1000 Power to Gas demonstrator is led by ENGIE subsidiary GRTgaz. Several partner companies are involved in implementing this innovative project:
Power to Gas technology offers a potential pathway to the future at global level. Around 50 projects are now under development worldwide; 20 of those are in Europe, with the majority being based in Germany.
As a technology at the crossroads of ENGIE expertise, Power to Gas is a perfect match with the Group's commitment to clean energy development.
