Carbon removal technology provider Heirloom announced today that it has raised $150 million in Series B funding, with proceeds from the financing aimed at supporting the rapid scaling of commercial Direct Air Capture (DAC) technology. DAC technology is listed by the IEA as a key carbon removal option in the transition to a net-zero energy system. According to an Intergovernmental Panel on Climate Change (IPCC) climate change mitigation study, scenarios that limit warming to 1.5°C include carbon dioxide removal methods scaling to billions of tons of removal annually over the coming decades, with DAC positioned to potentially account for a significant portion of the total. Direct air capture (DAC) technologies extract CO2 directly from the atmosphere at any location, unlike carbon capture systems which are generally deployed at the point of emissions.
