Toyota has introduced a novel concept model that focuses on utilizing boil-off gas, specifically vaporized hydrogen, generated while driving to enhance the efficiency of liquid hydrogen as an engine fuel. The company aims to address the challenge of 'boil-off', a phenomenon where fuel evaporates due to external heat entering the tank. By demonstrating how the boil-off gas can be repurposed as a source of energy, Toyota is exploring ways to improve the overall energy efficiency of liquid hydrogen systems. The new technology involves sending the boil-off gas to a self-pressuriser that can convert it back to usable hydrogen fuel without relying on external energy sources. Additionally, the surplus gas from this process can be used to generate electricity through a fuel cell stack, further contributing to energy efficiency. Toyota's innovative approach not only enhances sustainability but also aligns with its efforts towards achieving carbon neutrality. By showcasing this concept in a motorsport event, Toyota is leveraging the platform to refine its technology and collaborate with partners for advancing sustainable automotive solutions. The company's commitment to environmentally friendly practices is evident in its focus on safely releasing any surplus boil-off gas as water vapor outside the vehicle, showcasing a holistic approach to energy management in the automotive industry.
