Jan 29, 2026 — The underground mining industry, long plagued by high emissions, safety hazards and soaring operational costs from diesel-powered machinery, is undergoing an unprecedented transformation driven by the widespread adoption of new energy equipment. Electric, hydrogen fuel cell and hybrid technologies are replacing traditional diesel systems, marking a pivotal revolution that promises greener, safer and more efficient underground mineral extraction globally.

For decades, underground mines have relied heavily on diesel-powered loaders, trucks, drill rigs and ventilation equipment, which emit harmful gases, generate excessive noise and heat, and require massive ventilation systems to ensure worker safety — a costly and energy-inefficient process. According to McKinsey, diesel-powered underground mining equipment accounts for 31.4% of global non-road mobile source emissions, while ventilation for these machines alone consumes 40% of a mine’s total energy expenditure. Additionally, diesel equipment poses significant fire risks in confined underground spaces and demands frequent maintenance, further straining mine operators’ budgets.

This status quo is rapidly changing as new energy technologies mature and policy pressures for carbon neutrality intensify. Battery-electric equipment has emerged as the front-runner in the transition, with major advancements in energy density, charging speed and durability tailored to harsh underground conditions. Caterpillar, a global leader in mining machinery, recently demonstrated its first battery-electric underground mining truck prototype in Tasmania, Australia, in collaboration with Newmont Mining. Paired with its existing CAT® R1700 XE LHD battery-powered underground loader, the solution delivers a fully electric loading and transportation system for underground operations, eliminating emissions and enhancing safety through automation Caterpillar.

In China, new energy intelligent loader that integrates lithium iron phosphate battery systems and intelligent control technologies have been lanched. Deployed in mines, the loader achieves zero emissions, reduces energy costs by 81.7%, cuts carbon emissions by 58.1% and boosts power performance by 14.4% compared to traditional diesel models. It also supports remote operation, keeping workers away from hazardous underground environments and achieving 1,200 hours of trouble-free operation.

Hydrogen fuel cell technology is also gaining traction in extreme underground scenarios, addressing the limitations of battery-electric equipment such as long charging times and limited battery use time. A demonstration project in Pennsylvania, USA, developed a hydrogen fuel cell-powered coal mine vehicle that uses coalbed methane to produce hydrogen on-site, combining the zero-emission advantage of electric vehicles with the mobility and energy density of diesel systems. This innovation eliminates the safety risks of tethered electric vehicles and the charging bottlenecks of battery-powered models, while reducing operating costs significantly.

Policy support is a key driver of this revolution. Governments worldwide are rolling out stringent environmental regulations and incentive programs to accelerate the transition. In China, authorities have issued guidelines targeting 30% penetration of new energy equipment in underground mines by 2030, with central and local subsidies covering up to 30% of the purchase cost of electric mining vehicles. Globally, the European Union and North American countries have imposed strict emission limits on diesel mining equipment, forcing operators to adopt cleaner alternatives to avoid penalties.

Technological advancements are further fueling the shift. Battery charging speeds have been reduced to 30 minutes for 80% capacity, while electric mining trucks now boast load capacities exceeding 120 tons and a range of over 200 kilometers — meeting the demands of large-scale underground mining operations. Meanwhile, the integration of new energy equipment with automation and digital twin technologies is optimizing fleet management, reducing downtime and improving overall operational efficiency.

Market data reflects the accelerating pace of this transformation. The global underground mining equipment market is projected to grow from $17.1 billion in 2025 to $21.3 billion by 2035, with battery-electric systems accounting for the largest growth segment. In China alone, the market size of mining new energy equipment is expected to surpass 50 billion yuan by 2030, with a compound annual growth rate of over 25%.

Industry leaders emphasize that the new energy revolution in underground mining is not just an environmental imperative but also a strategic investment. “Electrification eliminates diesel emissions, improves working conditions and cuts energy costs by 40% to 70% — creating a win-win for miners, businesses and the planet,” said a senior analyst at Scania, a key supplier of industrial battery systems for mining equipment. Denise Johnson, President of Caterpillar’s Resource Industries Group, added, “Our collaboration with Newmont demonstrates that sustainable underground mining is achievable, and we are committed to delivering more zero-emission solutions to reshape the industry.”

As the revolution deepens, challenges remain, including the high initial purchase cost of new energy equipment and the need to upgrade infrastructure such as charging and hydrogen refueling stations. However, with declining battery and fuel cell costs, coupled with longer equipment lifespans and lower maintenance expenses, the investment payback period has been shortened to 3-4 years.

Looking ahead, the integration of new energy, intelligence and automation will define the future of underground mining. By 2030, new energy equipment is expected to become the mainstream in key underground mining regions worldwide, driving a 45% reduction in carbon emissions compared to 2020 levels and ushering in a new era of safe, green and efficient mineral extraction.
