Toyota's approach to utilizing liquid hydrogen in racing showcases innovation and efficiency. By utilizing 'boil-off' hydrogen from liquid hydrogen carried in the fuel tank of the Corolla Sport, Toyota addresses the challenge of hydrogen evaporating while the car is idle. The combustion engine powered by hydrogen eliminates emissions of carbon monoxide and unburned hydrocarbons, with lower levels of oxides of nitrogen produced and neutralized through exhaust after-treatment. Liquid hydrogen's energy density provides the Corolla with a potential for greater range than gaseous hydrogen. Toyota's strategy of capturing and utilizing boil-off gas not only powers the car's engine but also generates electricity using a hydrogen fuel cell stack. Any excess gas is converted to water vapor, minimizing waste emissions. Toyota aims to further develop this technology through technical partnerships, emphasizing the positive strides made in utilizing liquid hydrogen efficiently in the automotive industry.
