Caterpillar announced the launch of a three-year program to demonstrate an advanced hydrogen-hybrid power solution built on its new Cat C13D engine platform.
Starting in the first quarter of 2024, Caterpillar will develop a transient-capable system for off-highway applications. The project will demonstrate how state-of-the-art control systems and electric-hybrid components can help hydrogen-fueled engines meet or exceed the power density and transient performance of traditional diesel engines.
Caterpillar will serve as the prime contractor on the project, providing engine research and development as well as system integration. As the project progresses, other industry and academic collaborators will be brought into the program to provide additional specialist expertise. The initiative will be delivered at Caterpillar facilities in Chillicothe, IL and San Antonio, TX.
Unveiled at the CONEXPO-CON/AGG 2023 construction exhibition in March, diesel-powered versions of the Cat C13D engine offer eight power ratings from 456 to 690 hp (340 to 515 kW) with up to 3,200 Nm of peak torque. It provides up to a 20% increase in power and up to 25% more low-speed torque over the previous generation of Cat diesel engines in its power class.
The inline, six-cylinder Cat C13D enables the use of renewable liquid fuels such as 100% HVO, B100 Distilled Biodiesel, and even up to B100 Standard Biodiesel by working with the local Cat dealer. In addition to using hydrogen, its core architecture is designed for the future development of spark-ignited natural-gas capabilities.
Available for early OEM pilots in 2025 and scheduled for production in 2026, the Cat C13D engine is targeted for a wide range of off-highway equipment, including rock crushers, screeners, and grinders; trenchers; agriculture tractors, harvesters, self-propelled sprayers and woodchippers; material-handling equipment; and large industrial pumps.
