DeCarice's direct-injection hydrogen hybrid system is capable of up to 95% diesel displacement in industrial engines, offering high impact, low risk near-term decarbonisation.
About
Hydrogen is a globally used industrial gas with mature production and bulk distribution processes. It is also a key carbon-free fuel alternative for combustion engines. DeCarice's hybrid system integrates hydrogen gas direct-injection into diesel engines alongside traditional diesel injection, creating a hybrid power system operable with between 0 and 95% hydrogen substitution. Built on peer-reviewed research from the University of New South Wales Engine Research Laboratory, the closely controlled retrofit process is business friendly, adapting existing diesel fleets to flexibly tap into the hydrogen ecosystem, while increasing engine efficiency by typically 18% and cutting carbon output by up to 93%. Up-front Capex is minimised, asset replacement is avoided and existing operating and maintenance procedures are retained. DeCarice's hydrogen hybrid system provides heavy industry with a flexible, efficient, pragmatic solution for near-term decarbonisation.
Key Benefits
- Capable of 95% diesel displacement with hydrogen gas, driving 93% carbon reduction
- Engine efficiency increase by 18% over diesel baseline when operating on high hydrogen mix reduces total fuelling requirement
- Direct injection of hydrogen minimises contact with internal engine surfaces and retains durability and reliability expected from combustion engines
- Adapting existing asset avoids large up-front Capex and overheads
- Fallback to diesel-only operation, without operator intervention, assures uptime and controls business risks from hydrogen-related externalities
Applications
High-uptime, heavy duty industrial applications where electrification and hydrogen fuel cells are non-viable, diesel machinery is expensive and has long operating lifetime
Examples include: construction, power generation, mining and resources, long haul freight, container ports
