First sustainable fuel is on sale, but there’s a catch
British fuel specialist Coryton is selling a range of new sustainable gasoline aimed at classic car owners, but it will be hard to come by.
Coryton Sustain Classic is available in three grades: Super 80 contains at least 80 percent renewable content, Super 33 contains 33 percent sustainable fuel and Racing 50 is made from at least 50 percent renewables. Super 80 and Super 33 are 98 RON grade, equivalent to 94 Octane, while Racing 50 is 102 RON, or 98 Octane and aimed at motorsports. In each case there is less than one percent ethanol making the fuels suitable for older vehicles.
Unlike e-fuels, which use carbon captured from the atmosphere in their manufacture, Sustain is a bio-fuel made from agricultural waste, including straw, and crops which are unfit for consumption. The theory is that the fuel only uses carbon which already exists in the atmosphere and has been absorbed by the plants as they grow. As a result Coryton claims that its Super 80 saves 65 percent of greenhouse gas emissions compared with fossil fuel, with Super 33 saving 25 percent, and Racing 50 saving 35 percent.
“The availability of true fossil-free fuel components is limited,” says David Richardson, Business Development Director at Coryton. “So, we’re setting truthful and realistic goals, producing fuels that have a meaningful impact whilst meeting the demands of the user. While we could use ‘mass balancing’ techniques to certify this fuel as 100 percent, we believe that it is important to be open about technology readiness and traceability. The industry will get there with the right support – which is why we think it’s important to start getting these products into the hands of consumers so they can see how easy and effective the switch could be.”
Coryton prices its Super 33 at £3.80 per liter, ($17.91 per gallon) Super 80 costs £4.65 per liter ($22.12), and Racing 50 is £5.24 per liter ($24.92), making it considerably more expensive than the UK average price of around £1.60 per liter ($7.60) for high octane fuel.
The bigger issue is distribution, however, as Sustain Classic is currently only available from one supplier, Motor Spirit at Bicester Heritage, near Oxford, although more retailers will be rolled out soon. Coryton says that the company is “looking to extend the product to a wider community and have already had some discussions in the U.S.”
