UPS to deploy prototype Class 6 extended range fuel cell electric vehicle delivery truck; trials begin in Q3
. . . UPS is working with the US Department of Energy (DOE) and other partners to design a first-of-its-kind, zero tailpipe emissions, Class 6 medium-duty delivery truck that meets the same route and range requirements of UPS’ existing conventional fuel vehicles.
The UPS trucks are equipped with a 32 kW Hydrogenics fuel cell coupled to 45 kWh of battery storage and 10 kg of hydrogen fuel. Each FCEV produces electricity which continuously charges its batteries, thereby providing additional power and an extended range of 125 miles. This will support the full duty cycle of the truck, including highway driving.
The first FCEV prototype will be deployed in Sacramento, Calif., where UPS will validate its design and core performance requirements by testing it on the street starting the third quarter of 2017. Current project plans call for additional UPS trucks to be validated with at least 5,000 hours of in-service operational performance. . . .
The project is part of a fuel cell project grant awarded by DOE in 2013 focused on verifying the proof of concept in commercial delivery vehicles. The project calls for retrofitting conventional fuel trucks with fuel cell electric systems designed specifically for use in a delivery truck duty cycle.

As best I can see from the illustration, there are four H2 tanks stacked (two at the bottom, then 1 and 1) plus maybe the FC behind the driver's cab where the sleeper cab would normally go. So, a sleeper team tractor would need some other arrangement of tanks, but for the short-hauls this tractor is designed for it isn't an issue. If they can't find anyplace to put them, then presumably LH2 would be needed.
