Hydrogen for the Highway
Hydrogen is considered a ‘good candidate’ to contribute to the decarbonisation of the road transport sector.
HEAVY DUTY TRUCK
Large truck fleets are among the biggest contributors to Green House Gas (GHG) emissions. Hydrogen dual fuel co-combustion is a realistic and reliable clean-fuel solution available now.
In partnership with Hydra Energy, CMB have converted several class 8 trucks to dual fuel co-combustion.
To deliver the hydrogen required for these trucks, Hydra Energy are implementing a system to recover, store and reuse waste hydrogen. Ultimately Hydra Energy aim to power a haulage fleet of up to 200 trucks.
In ongoing trials, each truck is seeing savings of up to 60 litres of diesel per 500km trip, giving unprecedented reductions in CO2 emissions.

REFUSE COLLECTION VEHICLE
In partnership with ULEMCo, CMB’s engineering team developed and delivered a number of Refuse Collection Vehicles (RCVs). Their powertrains have been converted to run hydrogen dual fuel.
Each vehicle has up to 9kg of usable H2 on-board, giving significant CO2 savings, specifically at part load and idle which is a high proportion of their operating cycle.
The dual fuel system installation cost is comparable to an equivalent CNG conversion, and delivers greater real world CO2 savings.
To date, CMB have delivered over 30 dual-fuel, co-combustion delivery vans, including Ford Transits and Mercedes Sprinters, to customers throughout the UK.
This unique co-combustion technology is capable of delivering >70% diesel substitution (therefore >70% CO2 savings) in real-world city driving.
The Euro V van achieved 59g/km CO2 emissions when measured at Millbrook’s emissions facilities, under Euro V test conditions, including significant NOx reductions.
Commissioned by ULEMCo, a Euro VI conversion (with a QCM modified ECU calibration) achieved similar savings in CO2 and NOx when tested over a WLTP cycle at MIRA.
The hydrogen dual fuel system has a range of 120-180 miles, automatically switching to diesel only when empty.
HYDROGEN FUEL CELL VAN
As part of an Innovate UK funded programme, a Fuel Cell Range Extender power module was developed to address the range anxiety and charging time concerns associated with battery powered electric vehicles.
This power module was developed for aftermarket fit, with limited impact on load carrying capability.
The Nissan eNV200 was chosen for this technology, almost doubling the effective range. The modular system was roof mounted, resulting in no impact on load space.
This project was completed in partnership with ULEMCo.
