Cummins Inc., Komatsu Ltd., and Wabtec are set to collaborate on developing hybrid powertrain solutions for heavy surface haulage mining equipment. The agreement, formalised through a memorandum of understanding, combines the engine expertise of Cummins, Komatsu’s global mining presence, and Wabtec’s drive system technologies to accelerate the introduction of hybrid systems that support the mining industry’s decarbonisation goals.
The partnership builds on a long-standing relationship between Cummins and Komatsu, now extending into hybrid technologies that can cut fuel use, improve productivity, and reduce operating costs. Hybrid systems work by capturing and reusing braking energy, offering faster cycle times and significant fuel savings while helping mining companies meet their carbon reduction targets. With retrofit options also being considered, the initiative promises solutions that can be applied to both new trucks and existing fleets.
Cummins has strengthened its position in hybrid development through its 2025 acquisition of First Mode assets, bringing additional engineering expertise and the ability to accelerate product timelines. Pilot hybrid units are expected to enter the market in the coming months, with results projected to show double-digit fuel savings. Komatsu, meanwhile, has reaffirmed its commitment to achieving carbon neutrality by 2050, viewing hybrid haulage trucks as a practical step toward lowering emissions without compromising performance.
For Wabtec, which already supplies drive systems to Komatsu, the collaboration extends its role in shaping next-generation mining equipment through advanced and optimised powertrain solutions. Together, the three companies aim to scale hybrid mining technologies before 2030, providing miners with proven, reliable options to support the global transition to low-carbon operations.
This agreement follows earlier joint decarbonisation efforts between Cummins, Komatsu, and Vale, including the development of dual-fuel haul trucks using ethanol-diesel blends. Both initiatives align with Cummins’ Destination Zero strategy, reflecting the growing momentum for partnerships that bring practical, near-term solutions to the mining industry’s sustainability challenges.
