Ultimate Cell Truck Engine

This retrofit fuel cell system improves engine efficiency by generating hydrogen on demand through electrolysis and delivering precise amounts into the engine air intake based on throttle input. Requiring no hydrogen storage, the technology is simple, safe and highly adaptable for construction plant. Its modular design, available in three or six-cell configurations, can be scaled to suit different types of equipment, while full patent protection and compatibility with diesel, petrol, LPG and ethanol engines ensure broad applicability. The system also meets both European and US standards, providing a practical pathway to lower-carbon construction operations.

The technology was successfully deployed on a rural greenfield project where the use of fully electric plant was not a viable option. With no reliable grid connection, limited infrastructure and significant costs associated with charging facilities or energy storage, traditional decarbonisation approaches were impractical. By generating hydrogen only when required, the system offers a low-cost, low-disruption alternative that enhances the efficiency of existing machinery without the need for new equipment, power upgrades or operational downtime.

The trial delivered immediate environmental and operational benefits. Over a six-week period, the technology achieved a 14% reduction in emissions while saving 430 litres of fuel, with no adverse impact on reliability, performance or productivity. These results demonstrate that meaningful carbon reductions can be achieved using existing plant, even in challenging operating environments where alternative low-carbon solutions are difficult to implement.

The wider industry potential is significant. Because the system can be retrofitted to existing fleets and requires no charging infrastructure or grid upgrades, it provides an accessible and cost-effective route to decarbonisation. If adopted at scale, the technology could help construction companies achieve substantial carbon and fuel savings while extending the productive life of existing assets, making it particularly valuable for rural, remote and infrastructure-constrained sites.
