Rio Tinto says a new way of treating iron ore for steel production could reduce emissions by 95 per cent. So what's the catch?
Rio Tinto iron ore boss Simon Trott gestures to where a $215 million research and development centre will be built, currently the site of a big shed, in Rockingham, south of Perth.That's right up there when it comes to big claims on carbon dioxide reduction.
Professor Dongke Zhang, the director of the Centre for Energy at the University of Western Australia, said there was no doubt it was technically doable, and he had done a similar experiment in his lab 16 years ago. Rio said it was working to ensure it only used sustainable sources of biomass and ruled out sources that supported logging old growth or high conservation value forests.Off the back of success under laboratory conditions, Rio is building its research and development centre in Rockingham to test the BioIron process at a semi-industrial scale.
Some analysts believe the cost of so-called green steel would need to fall by 50 per cent to be competitive with traditional coal-made steel.Energy economist at Curtin University's School of Civil and Mechanical Engineering associate Professor Liam Wagner was confident the price would drop. WWF's de-carbonisation manger, Nicole Wyche, said any step towards lowering carbon-dioxide emissions from manufacturing steel was positive.
