Revolutionizing Sustainability in Motorsports: Toyota’s Liquid Hydrogen-Powered GR Corolla

Toyota has gone a step further in the quest to embrace sustainability and the new Toyota GR Corolla  H2 Concept that runs on liquid hydrogen is a testament of this at the Super Taikyu Final  Fuji. This vehicle doesn’t only reflect the advancement in the world of motorsports but also is a concept of future energy systems such as hydrogen technology for energy storage and usage with energy recovery.

This is a major development in the quest to achieve carbon neutrality, and it also shows how hydrogen can transform energy storage, use, and recovery.

Why Liquid Hydrogen?

Liquid hydrogen offers unique advantages over its gaseous counterpart:

Higher Energy Density: More hydrogen can be stored in a tank of the same size, making it ideal for applications requiring compact and lightweight storage.

Clean Emissions: Hydrogen combustion produces only water vapor, eliminating harmful pollutants.

However, liquid hydrogen systems face a challenge: boil-off gas occurs when stored liquid hydrogen vaporizes due to external heat. Toyota’s innovative approach aims to capture, reuse, and optimize this boil-off gas for energy, reducing waste and improving system efficiency.

Toyota’s Breakthrough Innovations

Reusing Boil-Off Gas as Fuel

Toyota has developed a self-pressurizer that uses the pressure of the boil-off gas to re-compress it into usable hydrogen fuel. Unlike traditional systems, this process doesn’t rely on external energy sources, making it a self-sustaining solution.

Generating Electricity from Boil-Off Gas

Some boil-off gas is directed to a compact fuel cell stack, generating electricity through a chemical reaction. This electricity can power vehicle components, like the pump for the liquid hydrogen tank, improving overall energy efficiency.

Safe Disposal of Surplus Gas

Any unused boil-off gas is converted into water vapor via a catalyst, ensuring safe and clean disposal without environmental harm.
