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.

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.
