The new technique involves capturing carbon dioxide from seawater, while current carbon capture methods mostly focus on. “This is an emissions decrease, not a permanent and durable removal of the fossil carbon released from burning the methane gas,” he says.Īshcroft is considering a second carbon capture project either at the facility or at a nearby salt plant, and says it is vital that the UK government puts money behind two “CCS clusters” it has backed for the north-west and north-east of England. Researchers tap into worlds largest sink of CO2 for carbon capture. However, he says because there is no permanent storage of the CO2 at the Northwich site, it is eventually released to the atmosphere. A London-based startup that makes small, modular units to capture carbon emissions from smokestacks has raised 150 million from investors that include the venture arms of Chevron Corp., Saudi. Stuart Haszeldine at the University of Edinburgh, UK, welcomes the project, which he notes is similar to a coal plant in India that is using CO2 to make sodium bicarbonate. Some of the product, better known as baking soda, is also sold to the food industry. The company had been concerned that the CO2 captured from flue gas wouldn’t be a sufficiently high grade for the pharmaceutical industry, but the sodium bicarbonate made with it has been shown to be good enough for use in haemodialysis for people with kidney disease, and as an ingredient to control the pH in tablets. Most schemes to capture and reuse carbon actually increase emissions
