WHY THIS MATTERS IN BRIEF
Hydrogen powered and Lithium Ion battery powered electric vehicles have been battling for dominance for years, and now fuel cell technology is starting to hit the roads for real.

It’s been two years since Toyota and truck manufacturer Kenworth showed off a proof of concept for a semi-trailer truck powered purely by Hydrogen fuel cell technology, and recently they showed off the first of 10 planned trucks that later this year will start transporting cargo across the Los Angeles basin and to various inland cities, with the only emission being water.
In the first phase, the trucks, operated by Toyota, UPS and other transport firms, will haul goods from the LA and Long Beach ports throughout the LA area, the Inland Empire, the Port of Hueneme, and eventually to Merced.
In a second phase, Shell has announced it will build hydrogen filling stations in Wilmington and Ontario, California, to provide more opportunities for the trucks to refuel. Initially, the trucks will rely on three existing stations at Toyota’s Long Beach Logistics Services and Gardena R&D facilities.
The Fuel Cell Electric Truck (FCET) is based on Kenworth’s T680 truck, but instead of the class 8 truck’s diesel inline-6 there is a pair of Toyota Mirai fuel cell stacks and an electric drive system good for 670 horsepower and 1,325 pound-feet of torque. The range on a fill of hydrogen is estimated at 300 miles, and that range is twice that of a typical drayage trucks’ average daily duty cycle, according to Toyota and Kenworth.
In fuel cell-electric powertrains, a fuel cell stack combines hydrogen with oxygen from the air to form electricity in a process known as electrolysis. In Toyota and Kenworth’s fuel cell truck, power management systems can apportion the electricity from the fuel cells to the motors, batteries, and other components, such as electrified power steering and brake air compressors, in order to maximize efficiency.
Most commercial quantities of hydrogen are sourced via steam-methane reforming, a process that produces a lot of CO2 emissions. But there’s also the ability to generate hydrogen in a reverse-electrolysis process, where electricity created by renewable energy such as wind and solar power can be used to split water into hydrogen and oxygen.
There are currently more than 16,000 semi-trailer trucks serving the LA and Long Beach port complexes, and this number is expected to double by 2030, so there’s potential for serious sales if even a fraction of truck companies switch over to zero-emission options. However, other firms including Daimler and Tesla are offering or plan to offer battery based. electric trucks in direct competition to Toyota’s fuel cell trucks, so as the world’s vehicles wean themselves off their fossil fuel addictions it’s likely that the EV versus Hydrogen Vehicle (HV) battle will heat up, however, that said, personally I, along with many others, wouldn’t be too surprised if EV’s win out in the long term. It’s like watching the Betamax versus VHS wars all over again.
