Project Coeus is a three-year programme led by Perkins in partnership with Equipmake and Loughborough University’s Wolfson School of Mechanical, Electrical and Manufacturing Engineering. 24 million awarded to Equipmake, the project is developing a fuel-configurable hybridised industrial open power unit for off-highway applications. The system combines a configurable spark-ignited Perkins engine with Equipmake’s bespoke heavy-duty electric motor, silicon carbide inverter and associated power electronics.
Designed as a direct replacement for a diesel-engine power unit, it can be configured for hydrogen, ethanol, methanol or bio-methane and is intended to help off-highway manufacturers adopt lower-carbon fuels and electrification without fundamentally redesigning their machines. The advanced, fuel-configurable hydrogen hybridised industrial open power unit (IOPU) developed through the project is now being installed in a Terex Ecotec TDS 820 high-performance shredder for machine testing. The installation follows extensive development testing and the power unit’s first public showing at CONEXPO-CON/AGG five months ago.
Once the installation is complete, the demonstrator will undergo a series of tests at Perkins’ proving site to demonstrate the technology and assess whether the system meets the machine’s peak-load and transient-response requirements. Ian Foley, CEO of Equipmake, commented: “This is a proud moment for everyone at Equipmake. Our role in Project Coeus has been to deliver a custom-designed heavy-duty electric motor — paired with our own silicon carbide inverter technology and all associated power electronics — and integrate that with a Perkins engine.
The resulting hybrid industrial open power unit can cope with the extreme demands of off-highway applications and is packaged so it can sit within a genuine drop-in replacement for a diesel power unit. Moving from the test cell into a machine as demanding as a high-performance shredder is exactly the proving ground this technology needs. “Off-highway OEMs want to decarbonise without compromising productivity or re-engineering their machines from scratch, and hybridisation combined with lower carbon fuels such as hydrogen offers a practical route to doing that.
