DeCarice retrofits diesel engines so they can run on 95% hydrogen gas.
The diesel displacement solution, built on UNSW IP, leverages hydrogen as an established carbon-free industrial gas to enable the decarbonisation of heavy industry without compromising power or durability.
-
DeCarice adapts diesel machines to run as hydrogen hybrids. The machine’s engine is retrofitted with a UNSW-developed second injection system, which allows it to run on 95% hydrogen gas, creating a carbon benefit of up to 93% without compromising performance or durability.
The process involves minimal overheads and retains diesel-only capability. This flexibility uniquely connects the decarbonisation efforts of heavy industrial businesses with their operational realities.
-
- Heavy industrial operations rely on the power density and durability of diesel machines; however, they have also been given an imperative to reduce their carbon footprint.
- Existing clean power technologies can be disruptive to core value creation due to factors such as uptime capability, access to power, and lifecycle cost.
-
- Industrial businesses operating large fleets of heavy duty, complex diesel machines, with substantial decarbonisation commitments and clear barriers to electrification.
-
- Technology implemented in three distinct research engines at UNSW Engine Research Laboratory and emissions outcomes published in peer-reviewed journals.
- AUD1.29 million raised in pre-seed SAFEs from venture capital.
- Four pilot projects in pipeline, domestic and international.
