Toyota unveils liquid hydrogen GR Corolla at Fuji Race
Toyota Motor Corporation has debuted its innovative liquid hydrogen-powered GR Corolla H2 Concept at the final round of the ENEOS Super Taikyu Series 2024, held from November 16 to 17 at Fuji Speedway, Japan. The event marked a milestone in Toyota’s efforts to explore cutting-edge hydrogen technologies aimed at achieving carbon neutrality in motorsports and beyond.
Unlike gaseous hydrogen, liquid hydrogen boasts a higher energy density, allowing more fuel to be stored in a compact tank. However, it presents challenges, including the evaporation of hydrogen, known as boil-off gas. At Fuji, Toyota introduced a concept model that recovers and utilises this boil-off gas, which traditionally would have been released into the atmosphere.
Toyota’s self-pressuriser technology uses the pressure from the boil-off gas to convert it back into reusable hydrogen fuel without external energy input. Additionally, surplus boil-off gas powers a small fuel cell stack to generate electricity, potentially improving the energy efficiency of the entire hydrogen system.
This initiative aligns with Toyota’s broader vision of “Beyond Zero”, aiming to reduce negative environmental impacts and add value to society. By integrating hydrogen technologies into motorsports, Toyota seeks to advance the practical application of sustainable energy systems while fostering partnerships for further development.
“Motorsports offers a challenging environment where we refine technologies and collaborate with partners to push boundaries,” stated a Toyota spokesperson. The GR Corolla H2 Concept embodies Toyota’s commitment to innovation and its pursuit of carbon-neutral mobility solutions.
Toyota’s hydrogen initiative complements its contributions to the United Nations’ Sustainable Development Goals, focusing on creating a greener and more inclusive society. The company remains committed to advancing mobility technologies that prioritise sustainability and energy efficiency.
