Startup ‘Skyonic’ is testing a technology that can transform captured CO2 into bicarbonates, acids and limestone. Such a process could allow limestone to be extracted

from CO2 emissions. Joe Jones, a chemical engineer who has worked for more than two decades in the semiconductor manufacturing industry is commercializing this vision through the Austin, Texas-based startup ‘Skyonic’. He uses ‘SkyMine’, a technology that can capture CO2 from a cement plant’s exhaust stream and turn it from a gas into a solid. Currently, over 400 tonnes of food-grade bicarbonate (baking soda) and hydrochloric acid can be processed, meaning that SkyMine can generate $28 million in earnings annually. Mackinnon Lawrence, research director at Navigant Research says that many ‘startups’ are building demonstration projects turning carbon into biofuels. In 2005, LanzaTech, converted carbon monoxide- gases (produced by industries such as steel manufacturing and oil refining) into fuel and chemical products. The big question remains: Can they be scaled-up?   Watch this space! pollution(image from
