Sustainable Flight Fund also gets the right to purchase up to 500,000 tons of carbon dioxide removal
Heirloom’s proven technology uses limestone to absorb CO2
CHICAGO, Feb. 25, 2025 /PRNewswire/ — United today announced that the UAV Sustainable Flight Fund has made an investment in direct air capture (DAC) company Heirloom, adding Heirloom’s measurable, quantifiable carbon reduction technology to its already robust portfolio of decarbonization strategies. The Fund also entered into an agreement for the right to purchase up to 500,000 tons of carbon dioxide removal (CDR) to be delivered for the production of sustainable aviation fuel or permanently stored underground.
Heirloom’s already-proven and scalable technology accelerates the natural power of limestone to capture CO2 directly from the air – making it potentially one of the lowest cost pathways for removing carbon dioxide.
“Carbon capture is one of our country’s fastest growing, energy enabling pathways,” said Andrew Chang, head of United Airlines Ventures. “At UAV, our primary focus is finding solutions for decarbonization that are profitable. Heirloom’s technology aligns directly with this objective, offering a scalable and commercially viable approach and complements United’s commitment to net zero by 2050.”
“We are incredibly proud to welcome the United Sustainable Flight Fund as an investor and to work with them to scale our DAC technology,” said Shashank Samala, CEO of Heirloom. “By utilizing DAC as a dual-pronged tool that can both greatly reduce CO2 emission from aviation fuel and remove residual emissions, we are charting a true path to Net Zero aviation.”
Heirloom marks United’s third carbon capture investment but the first in a company commercializing direct air capture technology. DAC is one of two main forms of carbon capture utilization and storage, along with point source capture. Unlike point source capture which captures CO2 from a specific emitting source, like a power plant, DAC removes atmospheric CO2.
