Cameron Halliday’s breakthrough came in 2019 when he tested a type of molten salt called lithium-sodium ortho-borate that absorbed more than 95% of CO2. Today, he is the co-founder and CEO of Mantel, which is building systems to capture carbon dioxide at large industrial sites of all types. Mantel’s system can be added on to the machines of power stations and factories making cement, steel, paper and pulp, oil and gas, and more, reducing their carbon emissions by around 95%. The salts boil off pure CO2 that can be transported for use or stored underground. Mantel uses the heat from its process to generate steam for customers by combining it with water in another part of its system. “That steam is a useful revenue stream, so we can turn carbon capture from a waste management process into a value creation process for our customer’s core business — whether that’s a power station using steam to make electricity, or oil and gas refineries.” Halliday says Mantel’s system doesn’t have to change much to be used in different industries. “This is a pragmatic solution that’s not trying to reshape the world as we dream of it. It’s looking at the problem at hand today and fixing it.”
