T2 to Introduce Next-Gen Biofuel for Autonomous Trucks in Partnership with Idemitsu Kosan and Isuzu T2 (headquartered in Chiyoda, Tokyo), a startup developing autonomous truck driving systems, announced on July 2, 2026, a partnership with Idemitsu Kosan (headquartered in Chiyoda, Tokyo) and Isuzu Motors (headquartered in Yokohama, Kanagawa Prefecture) to introduce next-generation biodiesel fuel "Idemitsu Renewable Diesel (IRD)" for autonomous trucks used in long-haul trunk transportation. Trial use will begin this summer on an approximately 500-kilometer expressway route connecting the Kanto and Kansai regions. This initiative presents a new option for the logistics industry, where CO2 emission reduction is an urgent priority in pursuit of carbon neutrality by 2050. The effort proceeds under a clear division of roles among the three companies: T2 will continuously use IRD in actual commercial operations, Idemitsu Kosan will handle fuel supply and refueling infrastructure development, and Isuzu will provide vehicle maintenance services. Specific Framework of the Three-Company Collaboration T2 currently operates Level 2 autonomous trucks—vehicles that run under driver supervision—developed based on Isuzu's "Giga" heavy-duty truck. Among these vehicles, one unit used for corporate scheduled transport will begin trial use of IRD developed by Idemitsu Kosan. Taking this partnership as an opportunity, Idemitsu Kosan plans to promote the establishment of a refueling system utilizing portable fuel tanks. The goal is to create an environment where transport companies can use IRD more flexibly, without relying on fixed infrastructure such as conventional underground tanks. Furthermore, the company will explore the deployment of service stations dedicated to IRD refueling and the potential development of "blended renewable diesel," which mixes IRD with regular diesel fuel at a specified ratio. Isuzu positions next-generation biodiesel fuel as a key low-carbon solution alongside electrification in its pursuit of carbon neutrality. The company will provide repair and maintenance services for T2's autonomous
