The Project Cypress DAC Hub is planned to be sited in Southwest Louisiana and is designed to advance the commercialization of Direct Air Capture and Storage (DAC+S). Local carbon storage company, Gulf Coast Sequestration, will partner with Project Cypress to sequester captured CO2. It aims to capture more than 1 million tonnes of existing carbon dioxide (CO2) from the atmosphere each year and sequester the CO2 permanently deep underground. Battelle will act as the DAC Hub owner in partnership with technology providers Climeworks Corporation and Heirloom Carbon Technologies, Inc.

In September 2023, Microsoft announced a long term contract to purchase up to 315,000 metric tons of CO2 removal over a multi-year period from Heirloom, following the DOE’s selection of Project Cypress for up to $600 million in matching funding.
