Cambridge Carbon Capture proves technology at lab scale

Sep 30 2019

The company has developed a technology which removes CO2 from the atmosphere and converts it into a usable, versatile and marketable material with many potential commercial uses.

By offering a solution where all types and sizes of industry can eradicate their CO2 emissions, whilst making a profit, Cambridge Carbon Capture aims to enable all industry to become zero carbon, putting a halt on climate change permanently.

Following many years’ of development, the team of Cambridge scientists has now proven at a lab-scale that its patented CO2LOC technology can efficiently capture CO2 and convert it into a valuable by-product. The technology works via a two stage mineralisation process, which involves the reaction of magnesium hydroxide (MgOH2) with CO2 to produce magnesium carbonate (MgCO3). The magnesium carbonate is filtered out to form a rock-like substance, permanently storing the sequestered carbon in a solid form.

The by-product is strong and lightweight, extremely fire and water resistant, and has many different potential applications across a range of industries. Its fire-resistant property means that even a thin wall of the material can provide superior fire protection for buildings, and it can also be used in construction as an eco-friendly alternative to concrete fillers, blocks, tiles and plasterboard.

Before it is dried, the by-product has a ‘slurry-like’ consistency, and this slurry has been proven to effectively and quickly extinguish fire. The by-product is stable and non-toxic and can be converted into a cream form and Cambridge Carbon Capture is currently talking to potential partners in the paints, cleaning and cosmetics industries to explore different possible applications.

Michael Evans, CEO, Cambridge Carbon Capture, comments: “Each year, the world produces 40 billion tonnes of CO2. The current goal is for this to be reduced to zero by 2050 – but, we are fast running out of time, as the detrimental effects of climate change become more and more apparent every year. The thing is, the world cannot just halt all operations – until we can find an effective eco-friendly alternative, we still need fossil fuels, particularly in the heavy industries."

“Cambridge Carbon Capture offers a unique solution because it allows industry to continue to operate, but any carbon emitted can be captured and converted into a useful by-product which can be used either in their own operations or sold on for a profit. For example, a cement works could capture the CO2 emitted from the cement plant, and, using our process, can transform the captured CO2 into a filler in their ready mix concrete – it really is that versatile. The technology takes the concept of a circular economy to a whole new level, and the possibilities are endless.

“Now we’ve proven the technology in the laboratory, we now aim to prove it on an industrial scale, and for that, we need large amounts of investment. We’re currently in discussions with a range of organisations to establish partnerships for use of the technology, and are seeking investment to help us demonstrate our technology in real world applications. We are also developing a larger demonstrator, housed in a shipping container, which will enable us to trial our technology at all kinds of industrial sites, such as cement works, steel mills and power stations."
