In the UK, Green Air News reported that SkyNRG, a supplier and emerging producer of sustainable aviation fuels, has highlighted a global shortage beyond 2030 of waste fats, oils and greases, currently the primary feedstock for SAF production, and urged accelerated transition to alternative pathways to meet soaring demand for the new fuels. In its 2025 SAF Market Outlook, produced in collaboration with global business consultancy ICF, Amsterdam-based SkyNRG said the core HEFA feedstocks were used in about 82% of all announced SAF capacity to 2030. But it warns of a “HEFA tipping point” in just five years as demand increases not only for SAF but also competing uses for these ingredients, threatening future production of the fuel, according to the report. “The reliance on limited volumes of sustainable and scalable HEFA (Hydroprocessed Esters and Fatty Acids) feedstocks creates a stark risk that the SAF industry will struggle to continue growth after 2030 unless efforts are focused to ensure alternative pathways are developed and commercialized,” said the new report. “The considerable efforts over the past decade have built a solid foundation for the SAF industry, showing production is safe, scalable and sustainable. However, after 2030, demand is set to outpace the HEFA SAF production potential, urging the industry to shift towards a more diversified set of SAF policies and pathways,” it added.
