ExxonMobil and Porsche test renewable, low-carbon eFuels


ExxonMobil and Porsche are testing renewable racing fuels and low-carbon eFuels, with an ultimate goal to make them available for the general public in the future. The first iteration of Esso Renewable Racing Fuel — a blend of advanced biofuels — “will be tested in race conditions with Porsche’s high-performance motorsports engines during the 2021 and 2022 Porsche Mobil 1 Supercup race series,” the company said.


The focus is also on eFuels — synthetic fuels made from hydrogen and captured carbon dioxide. The eFuel will be sourced from the upcoming Haru Oni pilot plant in Chile that generates hydrogen, which is then combined with atmospheric carbon dioxide to produce methanol. ExxonMobil has the technology to convert methanol to gasoline, resulting in a low-carbon fuel. The Haru Oni is a collaboration with Siemens Energy and other partners. In the pilot phase, the companies aim to produce around 130,000 litres of eFuels by 2022, followed by 55 million litres by 2024 and 550 million litres by 2026.

The second iteration of Esso Renewable Racing Fuel will contain eFuel components. The eFuel is anticipated to achieve a reduction in greenhouse gas emissions of up to 85% when blended to current market fuel standards for today’s passenger vehicles.

eFuels are a good complement to our powertrain strategy. They allow our customers to drive cars with conventional combustion engines as well as plug-in hybrids with significantly lower greenhouse gas emissions. The collaboration with ExxonMobil enables us to test the eFuels under demanding conditions on the race track. This is a further step towards making eFuels an affordable and lower greenhouse gas emission substitute to conventional fuels. – Michael Steiner, Member of the Executive Board, R&D, Porsche
