ENGIE is working on developing solutions made possible by hydrogen: production of electricity and heat, storage of renewable energy and zero-emission mobility.

H2 is the symbol that conceals the most abundant chemical element in the universe. Hydrogen is all around us. Transforming this presence into a vector of energy is of environmental interest in more ways than one. For this reason, ENGIE is taking action and innovating essentially in three areas: mobility, “Power to Gas” and autonomous energy production systems.

Hydrogen at the heart of the energy revolution

When produced from renewable resources, hydrogen can supply low-carbon electricity and heat thanks to fuel cells. It is very versatile, and can be transported and stored in liquid or gaseous form. It can also be used in industrial processes as well as in producing, storing and transporting renewable energy.

This new sustainable and future-oriented sector is mobilizing all the entities and subsidiaries of ENGIE, including GRTgaz, GRDF, Storengy, GNVert, ENGIE Cofely and Tractebel ENGIE.

Producing hydrogen from renewable sources on industrial sites

Hydrogen is a gas traditionally used in the petroleum industry, the chemicals industry and electronics. It provides numerous effective solutions for manufacturing components, storing energy and transporting active gases. In the glass industry, for instance, it allows the manufacture of flat screens that are less polluting and more eco-responsible.

ENGIE offers a service consisting of on-site production of renewable hydrogen by electrolysis for industrial clients needing hydrogen for their processes. This gives customers the advantage of benefiting from locally produced energy, which therefore has no transport costs and a low environmental footprint. The offer, known as EffiH2, can also be rolled out on isolated sites (e.g. islands and regions that are remote from power grids).

Moving toward green mobility!

Hydrogen mobility is booming. There are more and more hydrogen vehicles and charging stations in our towns and cities.

Used as a fuel, hydrogen makes it possible to generate electricity using on-board hydrogen fuel cells. This makes it a complementary energy for vehicles equipped with gas-fueled internal combustion engines (buses, garbage trucks) as well as for electric vehicles. Hybrid cars operating with electricity and hydrogen can charge their batteries as they drive.

The use of hydrogen extends the range of electric vehicles to 500 kilometers per charge. What’s more, not only is the charging time reduced from 8 hours to charge an electric vehicle to 5 minutes for hydrogen, but the hydrogen used generates no polluting emissions or noise.

For all these reasons, ENGIE is developing hydrogen mobility solutions and has joined forces with Michelin to invest in Symbio FCell, a pioneering company in fuel cell technology and inventor of the first range extender for hybrid vehicles.

“Power To Gas”: a solution for storing renewable energies

Renewable energies are an effective solution to the energy and ecology challenges of today. But their intermittent availability can sometimes make them complicated to distribute.

With “Power to Gas” technology, surplus energy from renewable sources can be stored by converting it to hydrogen by water electrolysis or to synthetic methane (methane syngas) by a methanation process. The hydrogen and/or methane syngas produced can then be stored, injected into the natural gas network, employed for urban heating networks or converted into electricity thanks to fuel cells, thereby providing consumers with energy from renewable sources that is available at any time of the year, including at times of peak consumption.

The rollout of “Power to Gas” technology is still in the experimental stage.

Hydrogen, a carrier for bringing decentralized energies close to communities

The fact that hydrogen can be produced, stored and used locally is encouraging local authorities and businesses to develop hydrogen projects to support the development of wind, solar and biomass energies and green mobility.

Through its subsidiary Storengy, ENGIE is exploring solutions for storing hydrogen in its underground and surface natural gas storage facilities, in order to contribute to the development of local hydrogen-based initiatives.

Explanation from Storengy

Among other avenues of development, ENGIE is studying the use of hydrogen in conjunction with photovoltaic panels to produce electricity 24 hours a day from solar energy. This decentralized solution will enable tomorrow’s consumers to enjoy locally produced and 100% renewable energy. In Asia-Pacific, for example, ENGIE is developing this solution primarily to help remote communities which may not have ready access to power grids take advantage of clean, competitively priced energy.
