Liquid water Corolla with increased maximum output and CO2 absorption
Toyota Motor Corporation will be racing the No. 32 GR Corolla (Liquid Water Corolla), which runs on liquid hydrogen, at the Fuji 4 Hours of Super Taikyu Final Race (hereinafter referred to as the Final Race) to be held at Fuji Speedway from November 11th to 12th. Update and deploy.
This liquid water Corolla was entered by Rookie Racing. It is participating as the No. 32 ORC ROOKIE GR Corolla H2 concept (MORIZO/Masahiro Sasaki/Hiroaki Ishiura/Yasuhiro Ogura), with Morizo (Toyota Motor Corporation Chairman Akio Toyoda) also at the wheel.

Update points from the Autopolis match three months ago cover a wide range of areas, including engine performance, cruising range, vehicle weight, and CO2 recovery technology.
In terms of engine performance, the liquid hydrogen pump and boosting performance have been improved. It is said to have achieved output levels equivalent to gasoline engines and high-pressure gaseous hydrogen engines. The gasoline engine GR Corolla generates a maximum output of 224kW (304PS) at 6500rpm and a maximum torque of 370Nm (37.7kgfm) at 3000-5550rpm, which is thought to generate around 300PS.
In terms of cruising range, improvements include improving the accuracy of determining when the tank is full when refueling, reducing the amount of boil-off by reducing heat input into the tank, and optimizing the amount of injection when the accelerator is not fully open. The team will aim to complete 20 laps, compared to the maximum number of laps at the Fuji 24 Hour Race in May, which was 16 laps. The distance of one lap around Fuji Speedway is 4.563km, so the goal is to increase the distance from about 73km to about 91km.
The weight of the vehicle has also been reduced. We identified parts that can be made lighter by leveraging the safety knowledge we have gained so far. He will take on the race with a weight reduction of 50kg, from 1910kg at Autopolis to 1860kg.
The biggest topic is the installation of CO2 capture technology. This liquid water Corolla is equipped with a CO2 adsorption device at the air cleaner inlet. Next to it is a device that desorbs CO2 using the heat of the engine oil. The desorbed CO2 is collected in a small tank filled with an adsorption solution.
This technology was realized by using a filter coated with “an adsorbent that can desorb CO2 at a lower temperature than before” developed by Kawasaki Heavy Industries, which is working with Toyota to develop carbon neutral technology for Super Taikyu. It is said that he did.
Liquid water Corolla evolves into a running chemical plant
By achieving this CO2 adsorption, the liquid water Corolla, which used to be a carbon neutral car that ran by burning hydrogen, has become a carbon negative car. Of course, CO2 in the air is measured in ppm and is a small amount, but internal combustion engines run by sucking in a lot of air, and this technology is said to be compatible in that respect (Toyota Motor Corporation (Mr. Naoaki Ito, Engine Project Supervisor).
Internal combustion engines are particularly suited for generating heat, and this heat allows the adsorbed CO2 to be desorbed.
Vaporizing and burning liquid hydrogen is also similar to rocket technology. In addition to adsorbing CO2, the liquid water Corolla also desorbs CO2 and recovers it using an adsorption solution, which means that the liquid water Corolla has evolved into a small chemical plant and a running chemical plant. Gentleman drivers Morizo and Yasuhiro Ogura, and professional drivers Masahiro Sasaki and Hiroaki Ishiura will drive the chemical plant.
The final race will be a carbon neutral challenge, a carbon negative challenge, and a super endurance race that will attract attention.
