Aramco has launched Saudi Arabia’s first CO2 Direct Air Capture (DAC) test unit, capable of removing 12 tons of carbon dioxide per year from the atmosphere
Direct air capture (DAC) technologies extract CO2 directly from the atmosphere at any location, for storage or utilisation, unlike carbon capture which is generally carried out at the point of emissions,. It is the most expensive application of carbon capture, although the IEA points out that Innovation in CO2 use opportunities, including synthetic fuels, could drive down costs and provide a market for DAC. There are currently around 130 DAC facilities in various stages of development globally.
The Aramco pilot plant, developed in collaboration with Siemens Energy, will be used as a testing platform for next-generation CO2 capture materials and will also seek to achieve cost reductions that could help accelerate the deployment of DAC technologies in the region. Aramco and Siemens Energy intend to continue working closely together with the aim of scaling up the technology, potentially leading to the establishment of large-scale DAC facilities in the future.
Carbon capture is a key pillar in Aramco’s ambition to achieve net-zero Scope 1 and Scope 2 greenhouse gas emissions across its wholly-owned operated assets by 2050. The company is exploring options to capture CO2 both at the point of emissions and directly from the atmosphere, through its circular carbon economy approach and the deployment of innovative technology solutions.
The launch of the DAC test facility follows the announcement in December 2024 that Aramco and its partners, Linde and SLB, had signed a shareholders’ agreement progressing the development of a Carbon Capture and Storage (CCS) hub in Jubail, set to be one of the largest in the world. Phase one of the CCS hub will have the capacity to capture nine million tonnes of CO2 from three Aramco gas plants and other industrial sources, with the potential for expansion in later phases.
Ali A. Al-Meshari, Aramco senior vice president of Technology Oversight and Coordination, said, “Technologies that directly capture carbon dioxide from the air will likely play an important role in reducing greenhouse gas emissions moving forward, particularly in hard-to-abate sectors. The test facility launched by Aramco is a key step in our efforts to scale up viable DAC systems, for deployment in the Kingdom of Saudi Arabia and beyond. In addition to helping address emissions, the CO2 extracted through this process can in turn be used to produce more sustainable chemicals and fuels.”
In December, King Abdullah Petroleum Studies and Research Center (KAPSARC) and Climeworks, a global leader in carbon dioxide removal technology, signed a Memorandum of Understanding (MoU) to jointly explore and advance Direct Air Capture (DAC) technologies within Saudi Arabia. The MoU outlines a roadmap to assess the deployment of new DAC systems in the Kingdom, focusing on availability of natural resources including subsurface CO2 storage.
