Since 2017, Hexagon Purus and Toyota have been working together to develop fuel cell electric powertrain kits for Class 8 trucks, with a focus on reducing harmful emissions. This collaboration involved projects like the 'Alpha' truck used at the Port of Los Angeles and the 'Ocean' trucks in the ZANZEFF 'Shore to Store' program. The goal is to pave the way for zero-emission commercial transportation, recognizing hydrogen's crucial role in reducing emissions from heavy-duty vehicles. Toyota's partnership with Hexagon Purus extends to providing a one-stop solution for customers by integrating fuel cell stacks with hydrogen storage systems and battery packs. Toyota's manufacturing facility in Kentucky assembles dual fuel-cell modules for hydrogen-powered heavy-duty commercial trucks. The collaboration has received recognition from the California Air Resources Board, granting Toyota a Zero Emission Powertrain (ZEP) Executive Order for its heavy-duty fuel cell electric powertrain. This certification aids OEMs and truck operators in complying with the strict emissions regulations in California. The transportation sector, particularly in the U.S. and California, is under pressure to reduce emissions significantly. Regulations from entities like the EPA and CARB are driving the adoption of zero-emission vehicles, with a focus on commercial trucks, given their substantial contribution to emissions. By working towards incorporating more zero-emission vehicles like hydrogen-powered trucks, the sector aims to achieve the emission reduction targets set by international agreements like the Paris agreement.
