Heirloom to market lime-based DAC technology
US technology company signs MoU to use calcination process initially developed to abate cement industry emissions
US technology company Heirloom plans to market the first direct air capture (DAC) system using a CO₂ separation process initially used to abate emissions in the cement industry. Heirloom, the backers of which include Bill Gates’ Breakthrough Energy Ventures, has signed a memorandum of understanding (MoU) with US decarbonisation company Leilac to use its electric kiln technology under licence in a lime-based DAC process. Heirloom’s process uses lime in a novel carbonation process to directly capture CO₂ from the air and form limestone. This process accelerates the natural binding of CO₂ and lime from a period of years to just three days. After binding, the reformed limestone is fed back into
