Spiritus, the climate tech company pioneering cost-effective solutions for scalable direct-air-capture (DAC) of carbon removal, announced on May 17th it has entered into a memorandum of understanding (MoU) with Aramco, one of the world’s leading global energy and chemicals companies. It also announced it received an equity investment in the company in November 2023 from Aramco Ventures.

The two parties represented by Spiritus CEO and co-founder Charles Cadieu and Aramco Sr. Vice President Ali Al-Meshari signed the MoU in the presence of Jennifer Granholm, United States Secretary of Energy, and HRH, Abdulaziz bin Salman Al-Saud, Saudi Arabia’s Energy Minister. The historic agreement represents a technical collaboration to further enhance Spiritus’ novel sorbent technology with potential piloting and scale deployment within Saudi Arabia.

“Aramco has stated its ambition to achieve net zero Scope 1 and Scope 2 greenhouse gas emissions across its wholly-owned operated assets by 2050, and sees opportunities to build potential lower-carbon new energy business,” said Ali Al-Meshari, Sr. Vice President of Technology, Oversight & Coordination, Aramco.

“Innovative technologies deployed at scale can help reduce the costs of reducing carbon emissions, and we are investing in developing these through our R&D, venture capital, and technology deployment programs. We believe direct air capture has the potential to play an important role in reducing carbon emissions from hard-to-abate sectors of the economy, and we see Spiritus’ approach to have the potential to scale globally, and specifically in the Middle East,” he added.

The signing ceremony, held in Riyadh, Saudi Arabia, highlighted the innovation collaboration between the U.S. and Saudi Arabia to work towards their respective net-zero goals and ambitions.

Spiritus’ novel approach to direct air capture addresses the major cost challenges of current direct air capture approaches and includes reducing energy needs, passive air collection, and a proprietary sorbent material to remove carbon from the atmosphere at a tenfold increase in adsorption efficiency compared to existing methods.

The company develops a solid sorbent direct air capture technology with a modular design. The whole facility also looks like a carbon capture orchard rather than the traditional DAC fans. After the sorbents capture the CO2 from ambient air, they are collected from the orchard, and placed in a container where heat is applied to remove the CO2 they have captured. The desorption process is powered by clean energy. After the CO2 is collected, the sorbents can be returned to the carbon orchard and reused. The process is energy efficiency which is one of the reasons the company is able to lower its costs quite low.
