Toyota's ORC ROOKIE GR Corolla H2 Concept is a hydrogen-powered vehicle that runs on liquid hydrogen and participates in endurance races. The vehicle uses a sophisticated storage system to maintain hydrogen at -253 degrees Celsius, preventing boil-off gas. Toyota is exploring the utilization of boil-off gas to convert vaporized hydrogen back into fuel efficiently. Innovations include a self-pressurizer to increase gas pressure without extra energy, an advanced liquid hydrogen pump, and transitioning to an oval-shaped tank for 1.5 times increased storage capacity. Toyota is actively seeking partnerships to further develop its hydrogen technology, focusing on energy recovery systems and long-term environmental sustainability goals.
