Heirloom Raises $150 Million Series B to Rapidly Scale Commercial Direct Air Capture
Heirloom, America’s leading Direct Air Capture (DAC) technology provider, has raised $150 million in Series B funding. The round was co-led by Future Positive, and Lowercarbon Capital - which also invested in Heirloom’s Series A. A range of new industrial investors, including Japan Airlines Co., Ltd., Mitsubishi Corporation (Americas), Mitsui & Co., Ltd., and Siemens Financial Services, representing difficult to decarbonize sectors of the economy – automotive, shipping, aviation, and advanced manufacturing — also participated. This is a strong vote of confidence in Heirloom’s ability to be a leading pathway to net zero. The funding will be used to continue to drive down the cost of the technology, develop additional projects and provide the funding needed to subsequently access infrastructure capital.
New investors in Series B include: Future Positive, H&M Group, Japan Airlines Co., Ltd., Mitsubishi Corporation (Americas), Mitsui & Co., Ltd., MOL Switch LLC, Quantum Innovation Fund, and Siemens Financial Services among others. Repeat investors include leading climate and carbon removal investors like Ahren Innovation Capital, Breakthrough Energy Ventures, Carbon Direct Capital, Lowercarbon Capital, and MCJ Collective.
Since its founding in 2020, Heirloom has progressed rapidly to become one of the world’s leading DAC companies. Heirloom is part of the team building Project Cypress — a Department of Energy supported DAC Hub, which is eligible for up to $600 million in government funding, and which will bring one million tons of yearly CO2 removal capacity to Louisiana and will create nearly 1,000 new jobs. Heirloom has received strong bi-partisan U.S. political support, as demonstrated by their recently unveiled plans for a number of Louisiana facilities, including an initial 17,000 ton facility set to be operational in 2026. Late last year, Heirloom began operating North America’s first commercial DAC facility in Tracy, California, shortly after signing one of the largest CO2 removal deals to date with Microsoft. The company has also signed deals to provide carbon removal to Stripe, Meta, Shopify, JPMorgan, McKinsey, Workday, H&M Group, Autodesk, and others.
