The peloton behind Most of the field is not chasing this. The industry pledged net zero by 2050, a date safely beyond any sitting CEO’ s tenure, while Fortescue went and picked 2030. Its diesel-free Real Zero stays a purist’ s creed. A private gigawatt grid is a game only giants can afford to play.
Which is why Fortescue’ s next move matters most. It is turning its green grid into a product. Having built the batteryelectric locomotives and 6MW chargers for its own railway, it now plans
US $ 1.3bn government backing to repower Rio ' s Boyne aluminium smelter with renewables to sell that technology to other miners, marketing decarbonisation the way it once sold ore.
A US-Congolese consortium has agreed to wire up to 2GW of clean power into the Democratic Republic of Congo’ s copper and cobalt belt, the mines as anchor tenants of a new national grid.
None of it would matter if it did not pay. It does. Solar is now, as International Energy Agency chief Fatih Birol puts it,“ the new king of the world’ s electricity markets,” the cheapest power the agency has ever measured. For an industry built on diesel, that reprices the whole game.
If it works, the gigawatt mine stops being a cost centre and becomes an export in its own right, mining’ s newest commodity dug not from the earth but from the sun above it. The tanker, after a century, is finally being sent home.
