Carbon Capture at Scale: Engineering Solutions for Saudi Industrial Clusters

The National Imperative: Building Saudi Arabia’s Carbon Management Infrastructure

As Saudi Arabia accelerates toward its 2060 net-zero commitment, one technology stands at the center of the Kingdom’s climate strategy: carbon capture, utilization, and storage (CCUS) . With ambitious targets to capture and utilize up to 44 million tonnes of CO₂ annually by 2035, Saudi Arabia is building the infrastructure for what will become one of the world’s largest carbon management systems . This effort centers on the Kingdom’s major industrial clusters—Jubail in the Eastern Province and emerging hubs in the Western Region—where concentrated emissions create both challenge and opportunity for industrial decarbonization solutions.

For Darkstone Group, this national priority aligns perfectly with our core capabilities. Carbon capture construction Saudi projects demand precisely the engineering expertise, construction management, and infrastructure development skills that define our Industrial Construction division. From CO₂ capture facilities to pipeline networks and injection wells, we’re positioned to deliver the physical infrastructure that will transform Saudi Arabia’s industrial emissions from liability to resource.

The Saudi CCUS Vision: Scale and Ambition

National Targets and Strategic Direction

Saudi Arabia’s commitment to carbon management is unprecedented in scale and backed by substantial investment and international partnerships:

National Capture Target:

• 2035 Goal: Capture and utilize up to 44 million tonnes of CO₂ annually through large-scale CCUS hubs

• Hub Development: Integrated facilities planned for both Eastern and Western regions to aggregate industrial emissions

• Storage Strategy: Utilization of saline aquifers and geological formations with significant CO₂ storage potential

The Circular Carbon Economy Framework

Saudi Arabia’s approach to carbon management is grounded in the Circular Carbon Economy (CCE) framework, which views CO₂ not as waste to be disposed of, but as a resource to be managed through four key strategies:

• Reduce: Minimizing emissions through efficiency and process optimization

• Reuse: Utilizing captured CO₂ as feedstock for products like synthetic fuels, chemicals, and fertilizers

• Recycle: Converting CO₂ into valuable materials through advanced processing

• Remove: Permanently storing unavoidable emissions in geological formations

This framework guides the development of CCUS infrastructure across Saudi industrial clusters, creating opportunities for integrated solutions that capture, transport, and either utilize or store CO₂ at unprecedented scale.
