‘Multi-million-tonne’ direct air capture plans unveiled for US Gulf Coast

Gulf Coast Sequestration (GCS) and Climeworks have joined forces to develop what is believed to be the first direct air capture (DAC) and storage hub on the Gulf Coast of Louisiana.

Under plans laid out in a Memorandum of Understanding (MoU) inked today (21st Nov), the duo hope to remove one million tonnes of carbon dioxide (CO2) from the air annually by 2030, with the capability to expand to many millions of tonnes a year in the near future.

The partnership has started dialogue with local stakeholders toward developing an informed community benefits plan to engage interested parties in the region through the planning and development of the project.

Governor John Bel Edwards said the announcement was a “crucial part” of Louisiana’s plan to achieve Net Zero carbon emissions by 2050. “This significant agreement between a pioneering Louisiana company and the global leader in DAC technology is another step forward in diversifying and growing our economy,” he stated.


DAC is widely seen as an answer to lowering the planet’s atmospheric level of COand is the practice of capturing CO2 directly from the atmosphere. The CO2 can then be utilised in low carbon products, or permanently sequestered, to achieve negative emissions.

Jan Wurzbacher, co-CEO of Climeworks, said, “DAC is a key technology for removing unavoidable and historic CO2 from the air. Climeworks is excited to work with GCS on the development of a US hub to scale-up the DAC industry in support of a more economically and environmentally sustainable future in Louisiana.”

GCS matches Climeworks’ DAC technology with studied geologic pore space suited for  carbon storage projects.

Gray Stream, President of the Stream Companies, the owner of GCS, added, “DAC presents the inspiring possibility of reaching Net Zero or even negative carbon emissions. Together, GCS and Climeworks are uniquely positioned to bring this promise to reality in the Gulf Coast’s industrial corridor.”
