In an interesting collaboration, General Motors (GM) and Komatsu are set to pioneer hydrogen fuel cell technology in heavy-duty applications, specifically for Komatsu’s 930E electric drive mining truck, the world’s best-selling ultra-class haul truck. This partnership marks GM's expanded commitment to an all-electric future, leveraging its expertise in hydrogen fuel cell technology and joining forces with Komatsu, a global leader in mining and construction equipment.
Hydrogen fuel cells are emerging as a viable solution for electrifying applications traditionally reliant on diesel engines due to their lightweight nature and quick refuelling capabilities. GM and Komatsu aim to jointly design and validate a hydrogen fuel cell power module tailored for the challenging demands of the Komatsu 930E mining truck, which boasts a nominal payload of 320 tons.
Charlie Freese, executive director of GM’s Global HYDROTEC business, expressed GM's belief that fuel cells can play a crucial role in achieving a zero-emissions future, particularly in heavier-duty applications like mining trucks. The collaboration seeks to deliver zero-emissions propulsion to these robust vehicles, which play a vital role in various industries.
Komatsu, with a commitment to reducing global emissions by 50% by 2030 and achieving carbon neutrality by 2050, sees the fuel cell-powered mining trucks as a crucial component in their decarbonisation strategy. The collaboration with GM provides an additional pathway for decarbonisation, offering a solution beyond traditional charging methods without the need for additional charging infrastructure within mines.
Dan Funcannon, Vice President of North America Engineering and Development for Komatsu, emphasised the importance of cross-industry collaboration in finding sustainable solutions for mining and construction equipment. The alliance aims to address the pressing need for environmentally friendly alternatives in these critical industries.
The first prototype HYDROTEC-powered mining vehicle, a result of GM and Komatsu's collaborative efforts, is expected to undergo testing in the mid-2020s at Komatsu’s Arizona Proving Grounds research and development facility. Powered by over 2 megawatts of HYDROTEC power cubes, this prototype signifies a significant step toward revolutionising heavy-duty, emissions-free hauling.
GM's extensive experience in fuel cell research, spanning over 50 years, coupled with Komatsu's industry leadership, positions this collaboration to accelerate the adoption of lower-emission mobility solutions, contributing to the sustainability goals of industries beyond passenger vehicles. The alliance stands as a testament to the potential of hydrogen fuel cell technology in revolutionising environmentally conscious practices in heavy-duty applications.
