Heirloom Raises $150 Million to Scale Direct Air Capture Technology

Heirloom, a key player in Direct Air Capture (DAC) technology, has announced a successful $150 million Series B funding round. This milestone signals growing confidence in their ability to provide scalable, cost-effective climate solutions.

The investment will help Heirloom lower the cost of its innovative DAC technology and expand its deployment capacity.

The round was co-led by Future Positive and Lowercarbon Capital, both of whom were early supporters in Heirloom’s Series A funding.

A mix of new investors joined, including industrial heavyweights from sectors facing tough decarbonization challenges like shipping, aviation, and advanced manufacturing.

Japan Airlines, Mitsubishi Corporation (Americas), Mitsui & Co., and Siemens Financial Services were among the notable contributors.

“We believe DAC is all about cost, cost, and cost – and that it will only scale to make a meaningful difference on climate change if it is affordable,” said Shashank Samala, Heirloom’s CEO. “This is precisely why people are investing in Heirloom.”

A Diverse Group of Investors

The impressive list of new backers also includes H&M Group, MOL Switch LLC, and the Quantum Innovation Fund.

Their participation reflects confidence in Heirloom’s trajectory and technological leadership.

These investors recognize Heirloom’s pivotal role in addressing the urgent need for decarbonization in industries like shipping and automotive manufacturing.

By partnering with companies from diverse sectors, Heirloom strengthens its ability to implement its technology in real-world scenarios.

This collaborative approach showcases their commitment to reducing costs and achieving net-zero emissions.

Advancing Cost-Effective Climate Solutions

Heirloom’s unique approach to DAC revolves around limestone, one of the planet’s most abundant minerals.

By accelerating a natural process, their technology captures CO2 directly from the air in just three days. This speed is a significant improvement over the years it typically takes in nature.

Once the CO2 is captured, it’s extracted from the limestone using renewable energy-powered kilns.

The captured carbon is then permanently stored underground, ensuring a measurable climate benefit.

This process underscores Heirloom’s commitment to sustainable and scalable solutions for reducing atmospheric CO2.

Shashank Samala added, “Through our real-world deployments and continued technological advancements, we are demonstrating not only that Heirloom has a clear trajectory to the lowest-cost DAC solution – but that we are executing on that vision and delivering results.”

Future Impact and Expansion Plans

The $150 million raised will allow Heirloom to further enhance its DAC technology and build new projects.

By focusing on reducing costs and scaling up operations, the company is positioning itself as a leader in the fight against climate change.

This funding round also highlights the broader shift toward sustainable investments.

Companies like Japan Airlines and Siemens Financial Services see DAC as essential for achieving their own decarbonization goals.

Their involvement underscores how industry players are leaning into innovative solutions to meet global net-zero targets.

The Path Forward

Heirloom’s mission aligns with growing calls for affordable climate solutions.

By focusing on cost reduction and real-world application, the company is setting a precedent for how DAC can scale effectively.

This funding marks a significant step forward, but it also reinforces the importance of collaboration between innovators and industries to tackle the climate crisis.
