Charwood Energy is a French company focused on biomass energy recovery and, more broadly, on decarbonized energy solutions for thermal and industrial applications. Founded in 2006 by Adrien Haller and historically based in Brittany, the company has built over time a strong engineering and project-delivery capability spanning design, construction and commissioning of renewable energy systems. It is listed on Euronext Growth Paris under ticker ALCWE and ISIN FR001400AJ60, and is positioned as a niche growth company, recognized by Bpifrance as an “Innovative Company” and eligible for PEA and PEA-PME savings plans.
The group’s business model is integrated and tailor-made. Charwood Energy offers turnkey biomass heating plants, anaerobic digestion, hygienization and pyrogasification solutions to industrial customers, farmers and local authorities. These technologies are used to produce heat, electricity and green gases, including biomethane, bioCNG, bioCO2 and green hydrogen. The company relies on several specialized subsidiaries, including Charwood Innovation, W&nergy, LG Concept and Energy&+, which cover R&D, engineering, manufacturing and project execution. This structure allows it to address a wide range of needs, from district heating networks to more complex industrial decarbonization projects.

Over the following years, it accumulated significant operational know-how, having completed more than one hundred projects for third parties by the end of 2021, based on three core technologies: biomass combustion, anaerobic digestion and pyrogasification. Its 2022 IPO increased its visibility and provided additional resources to support growth.
The company is headquartered in Saint-Nolff, in Brittany, while its solutions are deployed across France and internationally. Its commercial footprint includes references with well-known names in industry and environmental services, and more recent partnerships with Verallia, Engie Solutions, IDEX and local public stakeholders. In February 2026, the company reported FY 2025 revenue of €9.3 million, up 86% year on year, highlighting a sharp acceleration in activity.
