The Clarity platform
Koble continues, “Together, they will provide multiple sources of hydrogen throughout the region, including over 1 ton of 100% renewable hydrogen per day at the heavy-duty station to be operated by Shell, enabling zero-emissions freight transport. Existing stations supplied by Air Liquide at Toyota Logistics Services in Long Beach and Toyota Technical Centre in Gardena will serve as important research and development locations.” Once on board, the fuel is
stored at 10,000psi. It sounds high but this is one of the features of hydrogen – low-pressure storage
just wouldn’t give an acceptable range. These trucks have a target of 300 miles between refi lls, which equates to two days’ work on a typical delivery route. Kenworth and Toyota have worked

hard together to ensure safety, Koble confi rms, “The hydrogen tanks have been extensively tested for durability,

repeated fi ling cycles and extreme conditions, such as fi re. These tests have demonstrated that the tanks can safely support daily operating conditions and Heavy-Duty Fuel Cell Trucks will be able to safely perform cargo hauls in and around the ports of Los Angeles.” The proof-of-concept generates 560hp (e) from the two Mirai fuel cell stacks and a 12kWh battery. Importantly, this is a relatively small battery to support class 8 load operations. Torque is suffi cient to move a fully loaded truck at 80,000 lbs from a complete stop at 20% gradiant. The waste – water – is exhausted through a port below the vehicle.
A MOMENT OF CLARITY It’s not just the truck market showing an interest in fuel cells, and in particular California with its refi lling infrastructure is advancing all the time. In April Honda Clarity fuel cell cars
started appearing at Honda dealerships in the Los Angeles and Orange County
