Idemitsu Kosan, T2, and Isuzu Join Forces for Next-Gen Biodiesel in Trucking

Collaborative Push for Biodiesel



In a groundbreaking initiative, Idemitsu Kosan, T2, and Isuzu have come together to drive the adoption of next-generation biodiesel fuel in the trucking industry. This partnership is a significant step towards achieving carbon neutrality, a goal set for 2050, especially critical within the transportation sector where CO₂ emission reductions are essential.

Next-Generation Biodiesel Fuel Introduction


Starting this summer, Idemitsu Kosan will supply its renewable diesel, known as Idemitsu Renewable Diesel (IRD), to T2. This fuel will be evaluated using T2's Level 2 autonomous trucks operating on the expressway connecting the Kanto and Kansai regions, covering approximately 500 kilometers. T2’s deployment of these self-driving vehicles allows for the real-world testing of IRD, which could mark a pivotal shift in how the industry fuels its fleets.

Meanwhile, Isuzu will provide maintenance and service for T2’s autonomous trucks utilizing IRD, ensuring that operations maintain the same efficiency as traditional diesel fuel. This aspect is crucial, as potential users have expressed concerns about the performance and durability of the new fuel. The companies aim to address these issues while demonstrating the efficiency of biodiesel refueling operations.

Addressing Challenges in Biodiesel Adoption


Despite the promising potential of next-gen biodiesel, challenges remain. The current infrastructure for biodiesel refueling is inadequate, and prices tend to be higher than regular fuels. There's also uncertainty regarding the impact of biodiesel on truck performance and repair services, making transport companies hesitant to adopt this greener alternative. The collaboration among Idemitsu, T2, and Isuzu is a proactive step towards creating a supportive environment for the wider use of biodiesel, with ongoing evaluations of the utility and effectiveness of IRD refueling.

Future Plans for Biodiesel Infrastructure


As part of this partnership, Idemitsu Kosan aims to enhance fuel supply flexibility by promoting the use of portable fuel tanks, thereby moving away from fixed infrastructure. This shift will enable transportation companies to adopt IRD more readily. Furthermore, the development of dedicated service stations for biodiesel and the exploration of blended renewable diesel options are being considered to advance the availability of this sustainable resource.

T2 has an ambitious vision of supporting Japan’s logistics industry through advanced autonomous driving technology. The company is preparing for the rollout of Level 4 autonomous trucks, which will enable a seamless transition between driver-controlled and unmanned operations on highways. Two transition points, known as Trans Gate, are set to be established in Kanagawa and Hyogo Prefectures to facilitate switching between driving modes. These points will likely include fuel tanks to enhance refueling convenience and efficiency, ultimately contributing to carbon neutrality.

Isuzu's Commitment to Multi-Faceted Low-Carbon Solutions


Isuzu is committed to advancing carbon neutrality through diverse pathways for developing power sources. The company recognizes next-generation biodiesel, alongside electrification, as a vital low-carbon solution that meets a variety of market needs. Through collaboration with Idemitsu Kosan and T2, Isuzu is focused on testing the usage of next-gen biodiesel while addressing various challenges to facilitate its implementation.

In conclusion, the partnership between Idemitsu Kosan, T2, and Isuzu marks a promising start in transforming the trucking industry towards more sustainable practices. By working together to promote next-generation biodiesel fuel, these companies are taking essential steps towards a greener future. As they research and develop better infrastructures for biodiesel, their efforts could pave the way for widespread adoption of environmentally friendly fuels in transportation.
