General Motors and Komatsu will co-develop a H₂ fuel cell power module for Komatsu’s 930E electric drive mining truck, the world’s best-selling ultra-class haul truck. GM, a leader in H₂ fuel c

ell technology, and Komatsu, a global manufacturer of mining and construction equipment, will jointly design and validate the technology.

 

Lightweight and quick to refuel, H₂ fuel cells are ideal for electrifying applications traditionally powered by diesel engines. H₂ provides an effective method to package large quantities of energy onboard the vehicle, without compromising payload carrying capacity.

Additionally, fuel cells provide an excellent zero tailpipe emissions solution for vehicles with extreme hauling requirements, like the Komatsu 930E mining truck, with its nominal payload of 320 tons. These vehicles typically operate at a single mine throughout their life, which simplifies the challenges of sizing and deploying an effective H₂ refueling infrastructure to service the vehicle fleet.

“At GM, we believe fuel cells can play an integral role in a zero-emissions future, helping to electrify heavier-duty applications, beyond passenger vehicles,” said Charlie Freese, executive director of GM’s Global HYDROTEC business. “Mining trucks are among the largest, most capable vehicles used in any industry, and we believe H₂ fuel cells are best suited to deliver zero emissions propulsion to these demanding applications.”

Komatsu’s fuel cell-powered mining trucks will provide an additional pathway for decarbonization beyond battery-trolley or battery-static charging solutions, without the need for additional charging infrastructure within mines.

Komatsu has set a target of reducing its global emissions by 50% by 2030 and a challenge target of achieving carbon neutrality by 2050. The plans for achieving these goals include reducing and eliminating emissions within the company’s product offerings, as well as in the company’s facilities and production of its products. Komatsu also works closely with its customers on reducing and eliminating emissions during product use through optimization programs supported by Komatsu technology and service solutions.

GM’s target is to be fully carbon neutral in both products and operations by 2040.

“Finding new ways to power the equipment our customers need to do the vital work of mining and construction is a critical part of our commitment to supporting a more sustainable future,” said Dan Funcannon, vice president of North America engineering and development for Komatsu. “This is essential work that requires cross-industry collaboration, and we are excited to be working with GM on this important solution for a haulage offering without tailpipe emissions.”
