Volvo to begin production on their electric trucks next year:
Green Car Congress wrote: The 16-tonne GVW Volvo FL Electric features a 185 kW electric motor, maximum power (130 kW continuous output); a two-speed transmission, propeller shaft, rear axle. Max torque from the electric motor is 425 N·m. Max torque on the rear axle is 16 kN·m.

The truck can be outfitted with 2-6 lithium-ion batter packs, totalling 100-300 kWh. AC charging is via the mains grid (22 kW) or DC fast charge via CCS/Combo2 for up to 150 kW.
It appears that Volvo's approach will be to replace the ICE with an electric equivalent. Here is a picture of the electric drive unit for these trucks:

ULEMCo to demonstrate heavy-duty truck converted to run on hydrogen

UK-based ULEMCo will demonstrate a Volvo FH16 heavy-duty truck converted to run on hydrogen. The ULEMCo truck uses hydrogen to power the vehicle using a combustion engine rather than via fuel cells and an electric motor. . . .

ULEMCo believes that using conventional engines and existing truck designs, rather than the full transformation needed for electrification, the time frame to the target of zero carbon emissions can be shortened significantly, at the same time reducing the cost of the change for customers.

ULEMCo has converted many vehicles from diesel to hydrogen dual-fuel, and these are in current active service around the UK. The demonstration vehicle will be the first all-hydrogen example, will have at least 300HP, and with 17kg of hydrogen on board, a range of just less than 300 km (186 miles) unloaded is expected. As hydrogen storage is the only additional hardware, a smaller reduction in payload is experienced than with other low emission approaches, ULEMCo said. . . .
