The two feeder series for Formula One aim to switch up their gas to be greener. Here's what to know about these news types of fuels.
What are sustainable fuels?
“Sustainable fuel” is a catch-all term for a bunch of different alternative ways of producing fuels for planes and cars with the goal of reducing their carbon footprint. It includes biofuels, which recycle organic materials into fuel but also carbon-capturing e-fuels that are made by taking carbon from the air, which is what F2 and F3 plan to switch to in 2027. But what all sustainable fuels have in common are their low net carbon emissions.
When it comes to e-fuels created by carbon capture, Nikita Pavlenko, the fuel program lead at the International Council on Clean Transportation, says there are two different sources—getting it directly from the atmosphere, or getting it from smokestacks: “You have a fuel that is pretty close to zero carbon, just produced from renewable electricity and carbon dioxide captured from the air or from a smokestack.
That strict direct-air carbon capturing is what differentiates e-fuel from biofuels and other sustainable power sources, and according to Pavlenko, it’s a very new technology. The F2 and F3 experiments will be one of the first large-scale applications of e-fuel, which has implications for the future of transportation.
Pavlenko says he’s excited that F1 is pursuing e-fuels, because of their very prohibitive cost. “F1 would be one of the use cases that’s best able to support the cost difference,” he says. “It’s a relatively small quantity [in relation to the quantity of non-sustainable fuels] and I assume there’s a high willingness to pay.”There are some concerns, however. The FIA will have to ensure that its e-fuel is made using renewable energy sources.
