Hydro-Truck Efficiency Record


100% Hydrogen fuelled zero emission engine reaches new levels of efficiency placing hydrogen combustion on the map for future heavy transport applications.


❱ ❱ High efficiency hydrogen power could provide alternative fuel source for heavy goods vehicles of the future


R


evolve Technologies and ultra-low emission hydrogen fuel


engineering company, ULEMCo have achieved


record breaking energy efficiency results for a 100% hydrogen fuelled zero emission engine. Thermal efficiencies of 45% have been demonstrated in engine control strategies being developed for the Mega Low Emissions (MLE) truck demonstrator unveiled last year.


DIESEL ENGINE ADAPTATION This milestone performance shows that it is possible to go well beyond previously reported energy efficiency results for hydrogen combustion, at the same time as achieving immeasurable NOx levels. It points to the realistic prospect of zero emission trucks running on 100% hydrogen in the relatively short term. ULEMCo’s approach of adapting existing diesel engine designs to run on hydrogen-diesel dual fuel has provided substantial learning on the opportunity for zero emission engines. This ultimately provides routes to the much quicker adoption of hydrogen in heavy duty applications than alternative approaches, which are still many years away from cost effective commercial availability.


A recent Committee on Climate


Change (CCC) report referred to hydrogen as potentially playing an important role for heavy-duty vehicles. Similar conclusions were reached

for longer range journeys in lighter vehicles, where the need to store and carry large amounts of energy is greater. The report acknowledges that although overall well to wheel efficiencies are less for hydrogen than for battery EV, the latter’s negative impact on payload means that according to the report, the aim should be to move HGVs to zero-carbon energy (ie electricity and/or hydrogen) where feasible by 2050. “These excellent results represent engine efficiency levels very similar to those seen with some fuel cell technologies”, said Amanda Lyne, Managing Director at ULEMCo. “Combining these results with our knowledge of how to ensure that the engine can operate over a wide performance curve gives us confidence in this approach. Vehicle operators, particularly in heavy duty applications, will have a truly cost effective option for very low carbon and zero emission driving in the future.”


DYNAMOMETER TESTING Paul Turner, Engineering Director at Revolve said: “Our highly qualified team has used dynamometer testing to develop our understanding of how to optimise hydrogen fuel use, whilst delivering immeasurably low NOx from engines that would be adapted for use with hydrogen. We are delighted with the speed with which these impressive results have been achieved.”
