Charwood Energy Group

What Charwood Energy Group does

Charwood Energy Group is a French, integrated renewable energy company specializing in biomass valorization, with headquarters in Saint-Nolff, Brittany. Founded in 2006 and listed on Euronext Growth Paris since June 2022 (ticker ALCWE), the group serves industrial manufacturers, agricultural operators, and local government authorities with decarbonized heat, electricity, and renewable gas solutions. Its core technology is pyrogazéification — a thermochemical process that converts solid biomass into syngas (hydrogen and carbon monoxide) while co-producing biochar for carbon credit generation. Solutions are delivered as modular containerized units or conventional plant construction, manufactured at the company's Brittany workshops.

The group operates through four specialized entities: Energy&+ handles engineering, procurement and construction of turnkey biomass energy plants; W&nergy (a joint venture with Eiffel Gaz Vert) operates as an Independent Power Producer selling energy via corporate Power Purchase Agreements; Charwood Innovation, created in 2024, is the first French R&D center dedicated to pyrogazéification and runs a working test module for biofuel validation; and LG Concept (40%-owned since 2023) supplies wood energy logistics across five platforms in western France. Revenue is generated through one-time EPC project delivery, own-account energy sales (cPPA, expected to scale from 2027), R&D and feasibility study services, and biomass module sales.

Commercial traction has accelerated meaningfully: H1 2025 revenue of €3.9M grew +56% versus H1 2024, the order book reached €10M (+127%), and full-year 2025 revenue growth tracked at +86%. Notable enterprise customers include Verallia (3 MWth syngas PPA at the Cognac glass site — the first commercial cPPA for syngas signed in February 2025), ENGIE Solutions, Stellantis (via ENGIE for La Janais decarbonation), Idex, Dalkia, Terreal, Paprec, and Séché Environnement, alongside government customers including Région Bretagne and several communes. The company is also pursuing international expansion through a pyrogazéification unit in the Democratic Republic of Congo and selection into the Bpifrance/Business France Africa Accelerator program.
