Car manufacturer Toyota has introduced a concept model featuring a liquid hydrogen-powered GR Corolla that aims to enhance fuel efficiency using 'boil-off gas' generated while driving. The company envisions a more sustainable future by repurposing this gas, which is typically released into the atmosphere unused. This initiative was presented at the 2024 ENEOS Super Taikyu race series in Japan, highlighting Toyota's commitment to innovation and carbon neutrality through motorsports. The technology behind the concept involves converting boil-off gas into reusable hydrogen fuel using a self-pressuriser, eliminating the need for additional energy input. Furthermore, surplus gas is directed to a Toyota fuel cell stack to generate electricity for powering various components, thereby improving overall energy efficiency. The safe handling of any remaining surplus gas is ensured by converting it into water vapor through a catalyst. Toyota's proactive approach to utilizing boil-off gas not only enhances the efficiency of liquid hydrogen systems but also contributes to a more sustainable automotive industry.
