Hydrothermal gasification - White paper

This document is the result of a collective work initiated by the National Working Group 'Hydrothermal Gasification' aimed at setting up a French industrial sector by 2025. It puts forward strategic directions for this sector in regards to economic, technical and environmental aspects by bringing together a group of local authorities, industries and French agricultural producers. Its activities consist of waste and wastewater management and treatment companies, industrial production sectors (food industry, manufacturing, energy production, fertilizer industry, etc.) and the agricultural sector. It was officially launched in March 2021 during the Bio360 conference in Nantes, giving this technical solution a significant influence in the domain of renewable and low-carbon gas production, waste treatment and recovery. From 27 members to over 50 members since 2022, the collective of actors composing the working group supports the emergence and industrialization of Hydrothermal Gasification. Today, it covers a most of the value chain: developers, producers of renewable and low-carbon gases, waste treatment and recovery companies, users, equipment manufacturers, associations, industrial actors, engineering consultancies, gas network managers, research laboratories and local authorities. The main goal of this working group is to support the organisation of the sector on a national level by 2025, and growing it to a European level with the collaboration of foreign actors. In general, the working group aims to contribute to the objectives of the energetic transition, the ecological transition and the circular economy.
