Several institutional and economic players have reaffirmed their interest in pyrogasification at a digital conference organised on 21 October 2021 by GRTgaz. SYCTOM1, the Nouvelle Aquitaine Region, the Plaine de l’Ain Joint Local Authority, and CRIGEN2 all expressed this at the conference. GRTgaz are publishing a map of the projects launched in France to illustrate the regional dynamics of this energy sector of the future.

Technology overview and outlook
Pyrogasification is an innovative process for producing gas for injection into existing networks. This process transforms poorly recovered or non-recovered solid residues (used wood, non-recycled plastics, solid recovered fuels, etc.) into gases by heating them at high temperatures (between 800 and 1500°) with little or no oxygen.
Pyrogasification for injection has now reached a level of technological maturity that means we can envisage the construction of the first industrial facilities in France from 2023. By 2030, the network operators’ forecast assessment based on the goals set out in the regional plans (SRADDET3 and specific studies) shows that pyrogasification could represent 6 TWh of injected gas per year, i.e. up to 1 million tonnes of CO2 avoided.
This technology of the future will thus contribute to achieving 100% renewable or low-carbon gas consumption in France by 2050.

Overview of pyrogasification for injection in France
More than ten commercial projects and gas production demonstrators in France have already been made public. A wide range of stakeholders are involved in these projects (local authorities, waste treatment operators, manufacturers, equipment manufacturers, etc.).
