Wells drilled deep underground (1,800 meters in the Rosny-sous-Bois project) to access natural heat from the Earth's subsurface for district heating networks.

A thermal decomposition process applied to biomass feedstocks to produce hydrogen and other gases without carbon emissions.

A thermolysis-based process developed by Haffner Energy that produces renewable hydrogen from biomass by heating raw material to 450°C and extracting hydrogen molecules from the resulting gas mixture of carbon monoxide and hydrogen.

Greater Paris / Île-de-France

Marne, north-eastern France

Two geothermal wells (1,800 meters deep each) designed to tap into natural underground heat to supply heating to approximately 10,000 homes in the Greater Paris region, including Rosny-sous-Bois, Montreuil, and Noisy-le-Sec.

Geothermal energy project being developed south of Paris at Bagneux.

Engie is developing five geothermal energy projects around the Greater Paris region as part of an acceleration in renewable heating infrastructure.

A hydrogen no carbon technology that enables production of renewable hydrogen by cracking biomass through thermolysis at 450°C. The process extracts hydrogen molecules from a gas mixture of carbon monoxide and hydrogen released by heated raw material.
