What Haffner Energy does

Haffner Energy is a French publicly traded cleantech company (Euronext Growth Paris: ALHAF) that has developed a proprietary biomass thermolysis platform for producing renewable hydrogen, syngas, sustainable aviation fuel, renewable methanol, and biochar. The underlying technology decomposes residual biomass at approximately 500°C under anaerobic conditions to generate a hydrogen-rich renewable syngas branded Hypergas, which contains more than 45% hydrogen by volume and serves as the central intermediate for downstream products. The portfolio spans large-scale HYNOCA Flex S-iG units (12 tonnes/day of hydrogen plus 58,000 tonnes/year of biogenic CO2) and the standardized C-iC modular line for mid-sized decentralized projects, down to H6-generation units for sub-10 MW applications. The platform is protected by 15 patent families covering more than 80 international patents and draws on 33 years of operational experience across 40+ cogeneration projects totaling 600 MW in Europe and Africa.

The company monetizes through three primary channels: direct sale of standardized and bespoke industrial units (HYNOCA, SYNOCA, C-iC line); technology licensing and joint ventures with regional partners such as IGNIS P2X (Spain), Mundi Énergies (Canada), LanzaJet and LanzaTech (SAF), and OroCarbo (California biomethanol); and engineering, procurement, construction, and commissioning services alongside the Biomatch biomass supply advisory. The CORE100 reservation program, launched in February 2026, introduces a deposit-backed reservation system for 100 standardized C-iC units targeting more than €300 million in sales over three years, with first units scheduled for commissioning in summer 2027. Customers are exclusively enterprise-scale industrial operators, energy companies, project developers, and fuel offtakers in the aviation, maritime, chemicals, and mobility decarbonization segments. The company is targeting EBITDA-positive status from the fiscal year beginning April 1, 2026, with an EBITDA margin above 10% in the following year.

Haffner Energy is a French family-controlled business (the Haffner concert holds approximately 15.93% of capital and 26% of voting rights as of May 2026), listed on Euronext Growth Paris since February 2022 and headquartered in Vitry-le-François with offices in Paris, Nantes, and Houston. Strategic positioning targets hard-to-abate sectors where biomass-derived fuels offer carbon-negative or carbon-neutral alternatives to fossil feedstocks, with biochar co-production enabling carbon removal certificate revenue on top of fuel sales. Recent expansion has added operations in Spain, Canada, the United States (California), and India, supported by partnerships with energy majors, technology licensors, and project developers.

Core offering

Haffner Energy designs, manufactures, and licenses proprietary biomass thermolysis technology and modular industrial units that convert residual biomass into renewable hydrogen (HYNOCA), renewable syngas (SYNOCA/Hypergas), sustainable aviation fuel, and renewable methanol. The company sells standardized C-iC modular units and custom industrial installations, and provides EPCC engineering services and Biomatch biomass supply advisory to industrial operators, energy companies, and project developers globally.

Product overview

Haffner Energy is a cleantech company offering a portfolio of proprietary biomass thermolysis-based products for decentralized renewable gas and clean fuel production. The core technology platform consists of Hypergas® — a hydrogen-rich syngas produced via thermolysis of residual biomass — which serves as the foundational intermediate for multiple end products: HYNOCA® (renewable hydrogen), SYNOCA® (renewable syngas), Sustainable Aviation Fuel (SAF), and Renewable Methanol. The portfolio spans from large-scale Flex S-iG units (12 t/day H₂) to the standardized C-iC modular line for mid-sized projects, all the way down to compact H6-generation units for small-scale (<10 MW) applications. Biochar is a key carbon-negative co-product used for soil amendment, construction materials, and carbon credits. The company also provides EPCC/EPCM engineering services and Biomatch advisory for biomass supply chain management.
