Haffner Energy launches SB-HEFA process to produce renewable diesel, SAF
In France, Haffner Energy launched SB-HEFA (Solid Biomass to HEFA), an innovative process for producing renewable diesel and SAF based on its proprietary thermolysis technology, which directly converts solid biomass into liquid without going through syngas.
Haffner Energy’s thermolysis technology already generates oil, which is immediately converted into non-condensable gases in the process used to produce syngas, hydrogen, methane or methanol. The SB-HEFA process eliminates the reforming step used to convert the oil into gas. Instead, the thermolysis oil is extracted and stabilized through immediate cooling, before undergoing filtration followed by hydrodeoxygenation using proven technologies from the HEFA industry.
“The strength of SB-HEFA lies in combining our existing core technology with a simple, already industrialized conversion chain. By radically transforming the economics of renewable diesel and SAF, SB-HEFA creates the conditions for their large-scale deployment. This represents a paradigm shift for both markets,” said Philippe Haffner, Chairman and Chief Executive Officer of Haffner Energy.
Several major players in the aviation ecosystem have already entered into discussions with Haffner Energy regarding SB-HEFA, the firm said.
Haffner Energy said it plans to commission a first complete industrial demonstrator as early as 2027/2028, while non-hydrotreated oil can already be produced today at its Marolles site.
