Axens has licensed its proprietary Vegan HEFA (Hydroprocessed Esters and Fatty Acids) technology to Dragonfly Holdings to develop several sustainable aviation fuel (SAF) production facilities across Africa and the Caribbean. Under the collaboration, Dragonfly will implement Axens’ established HEFA process to produce SAF.

What opportunities and challenges do you see for scaling HEFA-based SAF production in Africa and the Caribbean, particularly around feedstock sourcing and infrastructure?

HEFA lives or dies on steady UCO/tallow supply and clean hydrogen - what’s the plan for feedstock logistics and on-site H2 (SMR/ATR vs import) in those regions? And with grid reliability a question in parts of Africa/Caribbean, are they building islanded power/steam so the hydrotreaters and compressors aren’t taking hard trips every week?

Proven kit, but success will come down to feedstock pretreatment and hydrogen. Are you designing for high-FFA UCO/tallow with robust phosphorus/metals/soap removal to protect hydrotreat/isomerization catalysts, and what’s the low-CI H2 plan (off-gas/propane recovery plus SMR with CCS vs electrolysis)?
