British researchers have found a way to cut emissions of planet-warming carbon dioxide from steelmaking — and save money too.
Steel production accounts for about 7 per cent of the world’s carbon emissions. It is also difficult to decarbonise due its reliance on coking coal to turn iron ore into its raw metallic form.
In a paper published in the Journal of Cleaner Production this month, scientists at the University of Birmingham in England proposed using a form of the mineral perovskite to recycle the carbon dioxide that steelmaking blast furnaces produce. If they can make it work at a large scale, the process could drastically cut the industry’s emissions, without the need for expensive new equipment or machinery.
“We can almost completely close the loop. All of those harmful gases that were being released into the atmosphere are now being used for something useful, just recycled within the system,” said Harriet Kildahl, lead author of the study.
Currently, the most widely touted alternative to traditional steelmaking uses hydrogen, produced with renewable electricity, to turn iron ore into iron. It’s a process that has been known for decades, but steelmakers are only just beginning to invest in it due to its prohibitively high costs.
The perovskite mineral the researchers examined can turn carbon dioxide back into carbon monoxide, which can be cycled back into the blast furnace as an alternative to coking coal. That would substantially cut the cost of the process and make it far cheaper than hydrogen-based processes.
Crucially, the technology can also be retrofitted on to existing blast furnaces, cutting emissions by about 90 per cent and avoiding the huge new investments that hydrogen-based steelmaking requires.
A Perovskite is a type of crystal, made in this case from niobium, calcium carbonate, iron ore and barium carbonate. Perovskites have also been proposed as new forms of fuel and solar cells.
Niobium, regarded as a critical mineral, is only mined in Brazil and Canada, leaving major countries including the US and China reliant on imports. Currently, it is used in steel alloys, including to make cars lighter and more fuel-efficient.
“From a cost-effectiveness aspect, for reducing stranded assets, this will be a lot faster than the other routes,” said Yulong Ding, a professor at the University of Birmingham and co-author of the paper.
The method has been demonstrated in a laboratory but not at a commercial scale, which will be critical to proving its viability. Challenges include finding a material that can replace coking coal’s structural role in the blast furnace.
Commercial demonstration plants could be possible within five years, the authors said.

Labour dispute
The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.

UAE currency: the story behind the money in your pockets
The currency conundrum
Russ Mould, investment director at online trading platform AJ Bell, says almost every major currency has challenges right now. “The US has a huge budget deficit, the euro faces political friction and poor growth, sterling is bogged down by Brexit, China’s renminbi is hit by debt fears while slowing Chinese growth is hurting commodity exporters like Australia and Canada.”
Most countries now actively want a weak currency to make their exports more competitive. “China seems happy to let the renminbi drift lower, the Swiss are still running quantitative easing at full tilt and central bankers everywhere are actively talking down their currencies or offering only limited support," says Mr Mould.
This is a race to the bottom, and everybody wants to be a winner.
