Breaking ground on the new testing and training center in the Vitry-Marolles business park (Marne) near Haffner Energy’s headquarters, as announced in Q4 2023. This center is designed to operate for 8,000 continuous hour per year, including testing different types of biomass supplied by customers. The plant will display the full range of possibilities offered by Haffner Energy’s technology: production of renewable syngas, renewable hydrogen, even the co-production of electricity, biochar, and biogenic CO2 from the gasification of biochar.

Renewable syngas starts being produced at the new testing and training center in the Vitry-Marolles business park (Marne).
Next step: producing renewable hydrogen before the end of the year.
