Oil and gas giant Shell and sustainable aviation fuel (SAF) supplier SkyNRG have begun the supply of aviation biofuel to three major airlines at San Francisco Airport (SFO), the companies announced on 6 December.

The fuel – made from used cooking oil – is produced by US renewable fuel supplier World Energy at its Paramount refinery in Los Angeles. It will be supplied through SFO’s current refueling facilities and can be used by airlines without needing modification to their current fleets. The fuel will be used by international airlines KLM, SAS and Finnair.

“The initial phase of the arrangement aims to pave the way for longer term, more resilient supply chains for sustainable aviation fuels and reduce the carbon emissions of flights from San Francisco and other airports,” the joint press release said.

“The aviation industry faces a formidable challenge; how to grow safely and responsibly given the expected doubling of passenger numbers by 2037,” said Anne Anderson, vice president of Shell Aviation.

The industry has committed itself to cap net aviation CO2 emissions from 2020.

Jurriaan de Jonge, director of fuel supply and risk management from KLM, said “In the transition towards a sustainable aviation industry, it is the partnerships and cooperation that make a difference. KLM, SkyNRG and World Energy have been doing that successfully for years at LAX. We look forward to seeing the developments at SFO and supporting Shell and SkyNRG in their efforts."
