Anglo American unveils a prototype of the world's largest H2-powered mine haul truck

Anglo American unveiled a prototype of the world’s largest H2-powered mine haul truck designed to operate in everyday mining conditions at its Mogalakwena PGMs mine in South Africa.

The 2MW H2-battery hybrid truck, generating more power than its diesel predecessor and capable of carrying a 290-ton payload, is part of Anglo American’s nuGen Zero Emission Haulage Solution (ZEHS). nuGen provides a fully integrated green H2 system, consisting of production, fueling and haulage system, with green H2 to be produced at the mine site.

nuGen is part of FutureSmart Mining, Anglo American’s innovation-led approach to sustainable mining – which brings together technology and digitalization to drive sustainability outcomes, including its commitment to carbon-neutrality by 2040.

Duncan Wanblad, Chief Executive of Anglo American, said “nuGen is a tangible demonstration of our FutureSmart Mining program changing the future of our industry. With diesel emissions from our haul truck fleet accounting for 10%–15% of our total Scope 1 emissions, this is an important step on our pathway to carbon neutral operations by 2040. The mining industry is playing a considerable role in helping the world decarbonize, both through our own emissions footprint and the metals and minerals that we produce that are critical to low carbon energy and transport systems.

“Over the next several years, we envisage converting or replacing our current fleet of diesel-powered trucks with this zero-emission haulage system, fueled with green hydrogen. If this pilot is successful, we could remove up to 80% of diesel emissions at our open pit mines by rolling this technology across our global fleet.”

Tony O’Neill, Technical Director of Anglo American, said “We are incredibly proud of what our team, working with expert partners, has achieved in under three years. This is truly a world-class innovation and bears testament to our technical vision and determination to deliver a cleaner and smarter future for mining.

“It is these game-changing innovations that are exactly why we began our FutureSmart Mining™ journey in 2014, knowing how much of a difference we can make, including in the energy transition and across our societal footprint. Innovative, clean and independent power systems, such as our nuGen ZEHS project, offer a significant part of the emissions solution.”

Natascha Viljoen, CEO of Anglo American Platinum, said “PGMs play an essential catalytic role in many clean-air technologies, including related to hydrogen production and hydrogen-fueled transportation. As part of our market development work, we have for some years been working towards establishing the right ecosystem to successfully develop, scale up and deploy hydrogen-fueled solutions.

“Hydrogen has a significant and wide-ranging role to play in achieving a low carbon future – particularly as an energy carrier enabling the development of a renewables-based power generation system. We are particularly excited about the potential of nuGen, amongst other opportunities, as we work to champion the development of South Africa’s Hydrogen Valley.”

The H2 economy provides an opportunity to create new engines of economic activity. With a combination of abundant renewable energy sources (i.e. solar and wind), and as the world’s largest producer of PGMs, hydrogen is a strategic priority for South Africa and presents a significant opportunity for economic development, including the creation of new jobs and the development of the PGMs sector, while also contributing to South Africa’s decarbonization objectives.

Sébastien Arbola, Executive Vice President in charge of Thermal Generation, Hydrogen and Energy Supply at ENGIE, said "At ENGIE, we realize the importance of green hydrogen in the decarbonization of heavy-duty mobility, and we are dedicated to helping industry players accomplish their carbon neutrality goals. We are delighted to partner with Anglo American to provide renewable hydrogen for their proof of concept. Through this partnership, we aim to unlock the potential of green hydrogen in South Africa and pave the way for the decarbonization of the mining industry."

South Africa’s H2 valley

In South Africa, the Department of Science and Innovation (DSI) and the South African National Development Institute (SANEDI), in partnership with Anglo American, Bambili Energy, and ENGIE, are looking into opportunities to create a H2 valley. The proposed H2 valley will stretch approximately 835 kilometers from the platinum group metals-rich Bushveld geological area in Limpopo province, along the industrial and commercial corridor to Johannesburg and to the south coast at Durban. The nuGen Zero Emission Haulage Solution is one of the first projects for South Africa’s H2 valley.

A feasibility study for South Africa’s H2 valley published in October 2021 identifies three hubs – Johannesburg, extending to Rustenburg and Pretoria; Durban, encompassing the city itself and Richards Bay; and Limpopo province centered around Anglo American’s Mogalakwena PGMs mine – with a fundamental role to play in integrating hydrogen into South Africa’s economy, and in establishing South Africa and its abundant renewable energy resources as a strategically important center for green H2 production. Nine key pilot projects have also been identified across these hubs and are recommended to be prioritized by developers. They span the transport, industrial, and construction sectors.

A world first, developed by Anglo American with its partners

For the nuGen project, Anglo American has worked with some of the world’s leading creative engineering and technology companies, such as ENGIE, First Mode, Ballard and NPROXX, to:

  • Design, build, and test a 1.2MWh battery pack, as the haul truck system uses multiple fuel cells that deliver up to 800kW of power, combining to deliver a total of 2MW of power.
  • Design and implement a software solution to safely manage power and energy between the fuel cells, batteries, and vehicle drivetrain.
  • Develop the power management and battery systems from the ground up, enabling us to tailor the system to each mine and improve overall efficiency by designing in energy recovery as the haul trucks travel downhill through regenerative braking.
  • Build a H2 production, storage, and refueling complex at Mogalakwena that incorporates the largest electrolyzer in Africa and a solar plant to support the operation of the haul truck.
