IndyCar Is Moving To 100% Renewable Ethanol In 2023

An anonymous reader quotes a report from Ars Technica: The IndyCar racing series is switching to an entirely renewable fuel next year. On Friday, ahead of Sunday's Indianapolis 500 race, IndyCar announced that starting next year, the race cars will be powered by a new, second-generation renewable ethanol race fuel developed by Shell. The manufacturing process for IndyCar's ethanol will be slightly less exotic than that seen in the low-carbon fuel that Formula 1 is considering for 2026. Rather than carbon capture and electrolysis, Shell will use sugarcane waste and other renewable feedstocks, which are hydrolyzed and fermented at a plant in Brazil operated by Raizen (Shell is a co-owner). Shell says that the switch "enables at least" 60 percent less carbon dioxide emissions than fossil fuel gasoline, although IndyCar currently runs on an E85 blend of gasoline rather than 100 percent fossil fuel or the 100 percent methanol that powered the sport for so many years. [...] Among other changes to help green the sport is the installation of a 150 kW DC fast charger at the Indianapolis Motor Speedway. And the roughly 5,000 tires that Firestone will transport to the track by Sunday will be hauled there from the tire maker's central Indiana warehouse by one of Penske's electric Freightliner eCascadia trucks.
