Heirloom Integrates Direct Air Capture in Northwest Louisiana

Published on: 

Heirloom is partnering with CapturePoint to permanently store the facilities’ captured CO2 in Class VI underground wells in northwest Louisiana.

Heirloom is building two direct air capture (DAC) facilities in Louisiana’s northwest region in the Port of Caddo-Bossier in Shreveport. The two carbon-removal facilities will be capable of removing approximately 320,000 tons of CO2 per year.

“We couldn’t be more excited to be building these new facilities in northwest Louisiana,” said Shashank Samala, CEO of Heirloom. “These investments not only bring economic activity and job creation to the region but also help to cement Louisiana in this new energy economy and further America’s leadership on the global stage. Coming shortly after we opened America’s first commercial DAC facility, this expansion in Louisiana continues Heirloom’s momentum as we work toward billion-ton scale.”

The first facility will begin construction in late 2024 and, with operation planned in 2026, will eliminate approximately 17,000 tons of CO2 per year. The second facility falls under Project Cypress—a regional DAC hub managed by the Department of Energy’s Office of Clean Energy Demonstrations, eligible for up to $600 million in funding. Heirloom’s portion of Project Cypress will remove about 300,000 tons of CO2 per year and the first phase, expected to be operational in 2027, can eliminate 100,000 tons of CO2 annually.


“Louisiana is well positioned to become America’s leader in safely storing CO2,” said Jeff Landry, Louisiana Governor. “Heirloom’s expansion into the Port of Caddo-Bossier means even more growth and more jobs for our state and is another example of driving the nation’s energy future. The expansion of Project Cypress Direct Air Capture Hub across the state represents the best of Louisiana—technology at the forefront of the energy economy and a broad base of skilled workers.”

The new DAC facilities in Caddo Parish will create approximately 1,000 construction jobs and more than 80 permanent positions, with additional jobs at full build-out. Louisiana supports the facilities through a $3 million performance-based grant for site infrastructure improvements. If payroll and employment targets are met, Heirloom could qualify for up to $7.8 million in state incentives over 10 years.

Heirloom and CapturePoint partnered to store the captured CO2 in Class VI underground wells—a durable and permanent storage solution. Both DAC facilities will be powered by renewable energy sources.

In November 2023, Heirloom opened the first U.S.-based commercial DAC facility, which will pull atmospheric CO2 into limestone rock and concrete for permanent carbon sequestration. The facility is in Tracy, CA, and was unveiled at a ribbon-cutting ceremony attended by local elected officials and the CEO of the PG&E Corporation.

Heirloom’s DAC facility is the first in the United States to capture CO2, permanently sequester it, and receive commercial removal purchases. Powered by renewable energy from Ava Community Energy and built with union labor, the facility has reached approximately 1,000 hours of operation time. Through a partnership with CarbonCure Technologies, CO2 will be permanently sequestered in concrete storage vessels, which will allow the facility to have a capture capacity of up to 1,000 tons of CO2 per year.
