DeCarice's direct-injection hydrogen hybrid system is capable of displacing up to 95% diesel from existing industrial engines, offering low risk near-term decarbonisation.
About
Hydrogen is a global 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 using world-class know-how from the University of New South Wales' Engine Research Laboratory, led by globally recognised combustion researcher Professor Shawn Kook (DeCarice CTO), the closely controlled retrofit process involves the upgrade of existing diesel fleets to flexibly transition to low carbon fuels, while increasing engine efficiency by up to 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.
Compared to incumbent hydrogen hybrid systems, DeCarice's key advantage is in dual direct-injection; injecting hydrogen gas directly into the engine's working cylinders independently of diesel injection enables precise combustion control and optimal emissions outcomes with minimised impact on the engine's durability. This approach has been more difficult to achieve and required the applied know-how of years of combustion research experience, but is now ready for scale-up.
Key Benefits
- Capable of 95% diesel displacement with hydrogen gas, driving 93% carbon reduction
- Fleet operators retain the same asset performance, ensuring minimal disruption to business as usual operations
- Engine efficiency increases by 18% over diesel baseline when operating on high hydrogen mix reducing total fuelling requirement
- Direct injection of hydrogen minimises contact with internal engine surfaces and retains durability and reliability relied on from combustion engines
- Adapting existing asset avoids large up-front Capex and associated overheads
- Fallback to diesel-only operation, without operator intervention, assures uptime and controls business risks from hydrogen-related externalities
