The hydrogen-powered Corolla, mobile liquid hydrogen stations, and carbon neutral fuel have evolved in the two months since the Round 2 NAPAC Fuji SUPER TEC 24 Hours Race from May 26 to 28.
Hydrogen-powered Corolla
Improved durability of liquid hydrogen pump
The durability of the pump, which was an issue in the Fuji 24 Hours Race, has been improved, resulting in 30% enhanced durability under similar conditions. Lubricating oil is usually used in pumps to reduce stress through less friction in the pump; however, lubricating oil cannot be used in liquid hydrogen pumps as it contaminates the hydrogen. For this race, a buffer structure will be used to reduce stress on the pump gear drive unit, aiming to allow it to finish the race without needing to be replaced.
