With the little Mirai model, Toyota is now one of three automakers selling fuel-cell vehicles in the U.S. market.
Now, the automaker is looking into potential heavier duty applications, including the possible of using hydrogen to fuel a fleet of zero-emissions trucks.
Such an approach could create a vast new market for hydrogen technology – and solve the problem that clean air proponents have had trying to figure out how to clean up truck emissions. Because of their size and weight, as well as range issues, current battery technology does not appear to be a good fit for large, long-haul trucks.
“Toyota has long maintained that hydrogen fuel cell technology could be a zero emission solution across a broad spectrum of vehicle types,” the Japanese maker said in a brief statement. “The scalability of this technology is enabling the automaker to explore a semi-trailer truck application for a California-based feasibility study.”
Fuel-cell vehicles rely on a system called a “stack” to combine pure hydrogen with oxygen from the air. That generates a flow of current that can be used to run the same motors found in a battery-electric vehicle.
The concept was first conceived in the 1850s, through fuel-cell technology only found serious application more than a century later, providing electricity for the Apollo moon craft. Automakers have been tinkering with hydrogen power for decades, but the recent launch of the Toyota Mirai, Honda Clarity and Hyundai Tucson Fuel-Cell Vehicle has kicked off the first serious effort at commercialization.
Toyota last month said it will begin selling hydrogen buses and will work with the Tokyo Metropolitan Government to get a fleet of those vehicles into service ahead of the 2020 Olympics which will be held in the Japanese capital.
The latest announcement could take things a significant step further, Toyota saying it has formed a unit within its U.S. research and development facility to see if hydrogen power could be used on heavy-duty trucks.
Such a move could have significant advantages in terms of reducing air pollution across the U.S. According to the Union of Concerned Scientists, medium- and heavy-duty trucks produce about 20% of the greenhouse gases from the transportation sector. And though federal regulations have clamped down in recent years, trucks also produce a disproportionate amount of smog-causing oxides of nitrogen and particulates.
There are technical challenges, however, that Toyota will have to address, including the scalability of fuel-cell technology. The good news is that electric motors produce large amounts of load-pulling torque.
