Microsoft has entered into a multi-year agreement to purchase up to 315,000 metric tons of carbon dioxide removal from Heirloom, a prominent Direct Air Capture (DAC) company. This deal is one of the largest carbon dioxide removal agreements to date, representing a significant milestone in carbon removal technology.
The agreement follows Heirloom’s selection for the DAC Hub program by the US Department of Energy, which could provide up to $600 million in matching funding. Project Cypress, situated in southwestern Louisiana, was among the two hubs selected to receive the highest levels of funding.
Heirloom’s Direct Air Capture technology utilizes the natural properties of limestone to capture CO2 from the atmosphere and permanently store it in various ways, including in concrete. This technology is among the most cost-effective DAC solutions available and has the potential to scale up to handle gigaton-scale carbon removal.
This deal with Microsoft will enable Heirloom to fund the construction of new Direct Air Capture facilities and accelerate the growth of the carbon removal market. It also underscores Microsoft’s commitment to its goal of achieving carbon negativity by 2030 and its investments in various climate change mitigation technologies, including renewable energy and energy efficiency.
This agreement between Microsoft and Heirloom represents a substantial step forward in the fight against climate change. It demonstrates corporate willingness to invest in carbon removal and provides crucial support for the advancement of this emerging technology.
