en.Wedoany.com Reported - Mazda tested its mobile carbon capture system during the third round of the Super Taikyu Series held in Japan from June 5 to 7, 2026, capturing 804 grams of carbon dioxide in 24 hours, an improvement of approximately 9.6 times over the 84 grams captured in previous tests.
This technology, called Mazda Mobile Carbon Capture, aims to capture some of the carbon dioxide that would otherwise be emitted from the exhaust pipe and store it inside the vehicle. The test vehicle was the Mazda Spirit Racing 3 Future Concept. The system works by passing engine-generated gases through a volcanic mineral called zeolite, whose porous structure adsorbs carbon dioxide molecules like a sponge. Subsequently, exhaust heat releases the adsorbed carbon dioxide, which is compressed by an electric compressor and stored in a tank mounted on the vehicle. Mazda confirmed that this is the first time the entire capture, separation, and storage process has been successfully integrated and demonstrated in a complete system.
In addition to the carbon capture system, the vehicle also used HVO, a renewable fuel made from recycled vegetable oil, further reducing its environmental impact. According to Mazda, the combined use of this fuel and carbon capture technology temporarily exceeded the emission levels of conventional vehicles, approaching the goal of achieving a negative carbon footprint. This project is part of Mazda's strategy for more sustainable mobility under the concept of "Driving Pleasure Drives a Sustainable Future." Based on these results, Mazda stated it will continue to refine this technology, aiming for carbon neutrality or even negative carbon emissions in future races, and plans to take a new step in the seventh round of the Super Taikyu Series in November this year.
