ETEC Hydrogen ICE Pickup Truck Conversion

|A conventional Silverado 1500HD|
ETEC (electric transportation engineering corporation) is developing a set of hydrogen-fueled internal combustion engine (HICE) Chevy Silverado 1500HD crew cab pickup trucks.
ETEC is primarily an infrastructure company for electric vehicles, providing design, engineering, construction, operation, maintenance, technical support and field services. It tackled HICE partly as an infrastructure opportunity.
Working in conjunction with Roush Industries, a provider of vehicle engineering and development services, ETEC is using the original GM 6.0-liter V8 outfitted with a Lysholm twin-screw supercharger/intercooler system optimized to provide acceptable power (180 hp) and torque (352 Nm) for pickup truck applications.
The conventional 1500HD with the 6.0-liter gasoline engine delivers 300 hp (224 Nm) with 488 Nm of torque.
ETEC uses a lean-burn strategy (lambda 2.0) to minimize NOx. The company estimates that engine out NOx will meet EPA Tier II Bin 7 specifications. It uses no catalysts for NOx reduction. One HICE Silverado is going to the DOE for more detailed emissions testing as part of the agency’s Advanced Vehicle Testing Activity, HICEV America program.
About 10.5 kg of hydrogen is stored onboard at a pressure of 350 bar (5,000 psi) in three 150-liter tanks secured in the truck’s cargo bed, providing a vehicle driving range in excess of 250 km (155 miles).
Nine conversion vehicles are currently in production. One goes to the DOE, as noted above. Powertech Labs, which provided the storage systems, purchased the remaining eight as part of the Industrial Waste Hydrogen Utilization Project in British Columbia (earlier post). Local businesses will lease the HICE trucks from Powertech for a two-year period.
