Haffner Energy is a French engineering and technology company that develops, supplies, and operates solutions to produce renewable gases and fuels from biomass and waste residues. Headquartered in Vitry‑le‑François, France, it serves industrial, energy, and mobility markets seeking to decarbonize with locally sourced feedstocks.
The company’s proprietary thermolysis and steam‑reforming platforms— including Hynoca for renewable hydrogen and Safnoca for syngas used in synthetic fuel pathways—convert a wide range of lignocellulosic residues into syngas, hydrogen, and fuel precursors, with biochar co‑production that can contribute to carbon removal. Haffner Energy provides process design, equipment supply, EPC/M services, and operations support for applications spanning refining, chemicals, district energy, and sustainable fuels production.
