By 2026, global Sustainable Aviation Fuel (SAF) production is projected to reach 2.4 million tonnes, yet this will account for only 0.8% of total aviation fuel use, according to the International Air Transport Association (IATA). This minimal penetration means immediate emissions impact will be negligible, despite urgent climate goals. For context, global e-SAF production capacity is a mere 0.02 million tonnes, highlighting the vast gap between ambition and reality.

Significant capital flows into SAF development, but its near-term impact on global fuel consumption remains critically small. This investment does not immediately translate into widespread decarbonization. Companies and governments are making crucial foundational investments, but the transition to truly sustainable aviation will be slow and capital-intensive, yielding widespread impact only after another decade.

The Surge in SAF Investment

Breakthrough Energy Ventures led a $43 million Series A financing for Lydian, a startup developing lower-carbon jet fuel, according to Citybiz. Breakthrough Energy Ventures' $43 million Series A financing for Lydian demonstrates significant investor confidence in advanced energy technologies. Concurrently, Delta Air Lines holds a five-year agreement with Shell Aviation to increase SAF availability at five U.S. airports, as reported by FlightGlobal, covering both first and next-generation SAF. Varied initiatives, from venture capital to airline partnerships, underscore a fragmented but determined push to establish foundational infrastructure, even as widespread impact remains distant.

Electrofuel (e-SAF)

Best for: Long-term, truly carbon-neutral aviation, leveraging renewable electricity.

Electrofuel (e-SAF) is a synthetic fuel produced using renewable electricity and captured carbon. Lydian develops this technology.
