Anglo American on Friday unveiled the world’s biggest green-hydrogen powered truck at a platinum mine in South Africa where it aims to replace a fleet of 40 diesel-fuelled vehicles that each use about a million litres of the fossil fuel every year.
The NuGen project at the Mogalakwena mine, owned by Anglo American subsidiary Anglo American Platinum, will use power from a solar plant to supply a hydrogen electrolyser to split water and provide the trucks, which can carry up 315t of ore each, with hydrogen fuel.
The project, which is expected to be fully implemented by 2026, is a first step in making eight of the company’s mines carbon neutral by 2030, according to Julian Soles, head of technology development, mining and sustainability at Anglo American. The company, which mines metals around the world ranging from iron ore and platinum to copper, has set a target of getting all of its operations to that status by 2040.
“People told us three years ago this is not going to happen, this is not a good idea. They are now beginning to take real notice,” Soles said at a presentation in Polokwane. “The vision for us is to see this rolled out across our business and the mining industry. It’s Anglo’s choice whether to commercialise this.”
The mining company, which dominated South Africa’s economy for eight decades before moving its headquarters to London in 1999, initially approached a number of equipment manufacturers with the idea of building a hydrogen-powered truck fleet. When it was turned down, it took the decision to convert its diesel fleet to use of the clean fuel itself.
About “80% of our diesel consumption at our large mines is through the use of large trucks”, Soles said. “What we actually had to build was a full ecosystem. A solar photovoltaic site, an electrolyser and a refuelling system to create a zero emission haulage system.”
No emissions
The use of hydrogen doesn’t emit climate-warming gases while diesel does. And with water being split to create the fuel using energy from the sun, there are no carbon emissions from its manufacturing process either.
The trucks are equipped with fuel cells that include platinum in their components. Mogalakwena is the world’s biggest open-pit platinum group metals mine.
Anglo and its global mining peers are under increasing pressure to cut greenhouse gas emissions and improve their environmental performance. The company last year spun off its South African thermal coal assets while rivals such as Glencore have pledged to reduce their emissions. — (c) 2022 Bloomberg LP
