Designed as a direct replacement for a diesel engine industrial open power unit, Perkins’ new hydrogen hybrid IOPU has completed development testing and is now being installed into a Terex Ecotec TDS 820 shredder to further test its capabilities in the field.
Based on the Perkins 1200 Series platform, the 1206 hydrogen hybrid IOPU is engineered to deliver 508 horsepower. The system is composed of an engine and integrated motor generator unit, which boosts performance, while an advanced hybrid cooling system reduces fuel consumption and noise from the IOPU with on-demand cooling technology.
Demonstrating the system in a real-world application is a key milestone for the Project Coeus team. The three-year project is a collaboration between Perkins, e-powertrain specialists Equipmake and Loughborough University’s Wolfson School of Mechanical, Electrical and Manufacturing Engineering, supported by UK government funding of $14.7 million through the Advanced Propulsion Centre UK.
The four spark-ignited fuels — ethanol, methanol, bio-methane and hydrogen — were used when developing the configurable combustion platform. The hybridized IOPU is designed to deliver a “robust and trusted fuel-configurable plug-and-play solution that produces reliable performance and is designed to meet global emissions standards, ensuring flexibility for the user,” the team says.
Powered byThe Ecotec TDS 820 shredder processes materials such as wood waste, biomass and construction debris to help customers recover reusable resources and reduce the amount of material sent to a landfill.
“While our products are already making a positive environmental impact through the work they perform, we're continually innovating to make the machines themselves more sustainable,” says Conor Hegarty, business line director for Ecotec. “Projects such as Coeus allow us to explore lower-emission technologies that can help meet future environmental requirements while continuing to deliver the power, reliability and productivity our customers expect from Ecotec equipment."
“The Peterborough Customer Machine Engineering Team (CMET) are currently integrating the hydrogen hybrid engine into the high-performance shredder,” says Andy Curtis, customer solutions director at Perkins. “Once that work’s complete, the machine demonstrator will undergo a series of tests at our proving site. We’ll be looking to demonstrate the proof of technology concept and that it achieves the peak load demands and transient response requirements of the machine.”
He adds: “The machine demonstrator will also help us define how to handle and utilize hydrogen within a real-world jobsite environment. This learning will allow us to support our customers’ machine development goals during future project phases.”
