The International Energy Agency (IEA) says that even if it works, carbon capture would have to be scaled up 100,000-fold by 2050 to hit net-zero targets.
Lhoist has turned to industrial gas giant Air Liquide for help to capture carbon emissions from its Rety plant.
They have developed a technology called CryoCap which will capture the gases and cool them down to -50 degrees Celsius when CO2 turns to liquid, said Nicolas Droin of Air Liquide.
The CO2 will then be separated and piped to a terminal in Dunkirk that will hold 1.5 million tonnes of the gas when it opens in 2028.
“INDUSTRIAL REVOLUTION”
The Lhoist site in Rety is not the only one in the area aiming to clean up its act.
A few kilometres away, a cement plant owned by Eqiom is also planning to sequester its carbon pollution and send it to Dunkirk.
“From there, it could be taken by ship to deep geological storage sites in the North Sea,” Boraccino said.
The whole project – estimated to cost €530 million (US$560 million), much of it with European Union funds – could, in the medium term, store up to 4 million tonnes of CO2 per year, according to Air Liquide and its partner, Dunkerque LNG.
That would enable steel giant ArcelorMittal, which is testing a different carbon capture procedure, to connect up to the terminal at some point in the future.
Patrice Vergriete, head of the urban Dunkirk authority, said the region is transforming itself through this low-carbon “industrial revolution”.
Carbon capture projects almost tripled globally in 2021 and have almost doubled again since then, according to the IEA.
But in a report in July, it also warned against relying on technologies that are “expensive and unproven at scale”. So far, it said, only 5 per cent of capture projects have got the green light from investors.
Instead, the IEA insisted that the best solution is to reduce the amount of CO2 being generated in the first place.
