UPS has unveiled a more efficient prototype delivery truck aimed at cutting both emissions and fuel costs. Powered by a hydrogen fuel-cell powertrain, which takes compressed hydrogen gas and converts it into electricity, with the only byproduct being water, the new trucks can store about 10 kilograms of hydrogen fuel and have an estimated range of 125 miles. UPS plans to deploy the first fuel-cell prototypes in Sacramento later this year. Additional fuel-cell trucks are planned to be rolled out in order to accrue about 5,000 hours of performance testing. Part of the money for this program originates from a 2013 Department of Energy grant focused on implementing hydrogen fuel-cell technology in commercial delivery vehicles.
