Innovation in formulating lower-carbon fuels

Aramco is an energy and chemicals company with oil and gas production as its primary business. The fuel mentioned here is not yet commercially available.

More efficient transport — across road, sea, and air — demands products that are safe, reliable, and cost-effective. At Aramco, we leverage the power of innovation to create solutions that can help deliver stable, realistic, and inclusive solutions to the energy transition.

Our advanced research and development centers around the world are investing in lower-carbon fuel formulations that are compatible with the existing transport infrastructure, from engines to turbines. These fuels aim to help reduce atmospheric carbon emissions from our everyday commute.

Driving innovation together

Exploring a lower-carbon fuel formulation for the track…

Aramco is working with motorsport teams and competitions to further test potential lower-carbon drop-in solutions.

In September 2022, we announced a partnership with Formula 2 and 3 to explore the introduction of Advanced Sustainable Fuels1. With 55% sustainably-sourced Aramco biofuel used in 2023 and 2024, F2 and F3 cars adopted 100% sustainable fuels2 in the 2025 season, in line with FIA technical regulations. Crucially, these lower-carbon solutions are “drop-in” fuels–meaning they require minimal work to replace traditional fuels in existing internal combustion engines.

In collaboration with F2 and F3, we aim to demonstrate the potential of lower-carbon fuels, leveraging our global network and technological expertise to help drive innovations that could support the development of lower-carbon passenger vehicles fuels.

“Our relationships in motorsports allow us to test these advanced lower-carbon fuels under extreme conditions, which helps to validate their potential. This testing is crucial and requires careful planning, as investments in such technology are both time — and resource-intensive, requiring careful planning.”

“The goal to switch to lower-carbon fuel can only be achieved through the partnership with a company of the scale of Aramco.”

Bruno Michel, CEO, FIA Formula 2 and FIA Formula 3

…before moving it to the road, sea, and air

We are investing significantly in lower-carbon fuels that have the potential to rapidly improving lifecycle emissions across cars, trucks, ships, and planes–without requiring new engines or turbines. This approach creates a bridge to more sustainable transportation.

The global automotive manufacturer Stellantis recently concluded that 24 engine families in European vehicles sold since 2014 – representing 28 million vehicles on the road – are ready to use advanced drop-in lower-carbon fuels without any powertrain modification.

“We are delighted to have worked with Stellantis in testing the compatibility of lower-carbon fuels with today’s vehicles. These results show that fuels produced through a lower-carbon pathway, can serve as a drop-in solution for existing cars.”

Powering progress

Regions with ambitious renewable fuel targets are creating emerging opportunities for lower-carbon fuels. We partnered with Repsol, the Spanish multinational energy and petrochemical company, to explore the production of lower-carbon synthetic diesel and jet fuel in Bilbao, Spain.

1 In this context, "Advanced Sustainable Fuels" refers to lower-carbon fuel formulations developed for motorsport applications. This usage aligns with the FIA's definition and may differ from broader industry terminology. For full FIA criteria, see “Invitation to Tender for Sole Supply Contract (2025–2026)”.
2 100% sustainable fuels derived from “Advanced Sustainable Components (ASCs)”, which must be sourced from non-food biomass, renewable feedstock of non-biological origin, or municipal waste, and meet stringent greenhouse gas emissions thresholds.
