The company focuses on energy engineering and biomass to energy projects. The company offers the HYNOCA process for the production of green hydrogen from biomass by thermolysis and is protected by patent families and other international patents. As a deep-tech renewable energy player on Euronext Tech Leaders, Haffner Energy is positioned to capture growing demand for alternative fuels and decarbonization solutions.
Cyborg Score Rationale
While Haffner Energy possesses differentiated proprietary thermolysis technology and operates in a strategically important market, the company faces significant challenges: severely depressed stock price (€0.053 from 52-week high of €1.158), negative EPS, and minimal market capitalization of €4.6M. Early-stage commercialization risk remains material despite 30+ years of R&D.
