GM and Komatsu join forces to create hydrogen fuel cell technology for Komatsu's 930E mining truck, aiming to revolutionize heavy-duty vehicle electrification, reduce emissions, and advance sustainability in the mining industry.



General Motors (GM) and Komatsu recently announced a groundbreaking collaboration to develop a hydrogen fuel cell power module for the Komatsu 930E electric drive mining truck, a global leader in ultra-class haul trucks. This alliance merges GM's expertise in hydrogen fuel cell technology with Komatsu's manufacturing excellence in mining and construction equipment, aiming to design and validate advanced technology.

Hydrogen fuel cells, known for their lightweight nature and swift refueling, emerge as a prime solution for electrifying applications traditionally reliant on diesel engines. Their capacity to store substantial energy without compromising payload carrying ability positions them as an ideal choice for vehicles like the Komatsu 930E, with a nominal payload of 320 metric tons.

These fuel cells offer a zero tailpipe emissions solution, particularly suitable for heavy-duty vehicles like mining trucks that primarily operate in a single mine. This simplifies the challenges of establishing an effective hydrogen refueling infrastructure, essential to service the vehicle fleet.

Charlie Freese, executive director of GM's Global HYDROTEC business, expressed GM's belief in the pivotal role of fuel cells beyond passenger vehicles. He emphasizes their suitability for empowering vehicles integral to industries, stating, "Mining trucks are among the largest, most capable vehicles used in any industry, and we believe hydrogen fuel cells are best suited to deliver zero emissions propulsion to these demanding applications."

Komatsu's adoption of fuel cell-powered mining trucks offers a distinct approach to decarbonization, diverging from battery-based charging solutions. This innovative move eliminates the need for additional charging infrastructure within mines.

Both GM and Komatsu have ambitious sustainability targets. Komatsu aims to reduce global emissions by 50% by 2030 and achieve carbon neutrality by 2050. GM aspires to achieve full carbon neutrality in products and operations by 2040.

The collaborative efforts of GM and Komatsu are geared towards testing the first prototype HYDROTEC-powered mining vehicle by the mid-2020s at Komatsu's Arizona Proving Grounds (AZPG) research facility. The vehicle will harness over 2 megawatts of HYDROTEC power cubes, showcasing the practical application of advanced hydrogen technology in heavy-duty mining operations.

GM's extensive experience in fuel cell research spanning over five decades aligns with Komatsu's commitment to sustainability. The joint endeavor aims to promote lower-emission mobility solutions beyond passenger vehicles, impacting diverse industries and facilitating the realization of sustainability objectives.

The collaboration between General Motors and Komatsu signifies a pivotal milestone in the journey toward sustainable mining practices. Their shared commitment to harnessing hydrogen fuel cell technology for heavy-duty mining trucks heralds a promising era of emissions-free, eco-conscious mining operations.
