Overview
Saudi Arabia’s investment in carbon capture, utilisation, and storage represents a strategic wager that hydrocarbons can remain part of the global energy system in a carbon-constrained world — provided their emissions are managed effectively. The Kingdom is pursuing one of the most ambitious CCUS agendas among hydrocarbon-producing nations, with a target to capture and store or utilise 44 million tonnes of CO2 annually by 2035. This initiative is not motivated by altruism alone; it is a defence of the Kingdom’s core economic asset. If Saudi Arabia can demonstrate that oil and gas can be produced, processed, and consumed with dramatically reduced carbon emissions, it strengthens the long-term demand outlook for hydrocarbons and protects the value of reserves worth trillions of dollars.
The CCUS programme intersects with multiple Vision 2030 objectives: it enables blue hydrogen production for export, supports the circular carbon economy framework aligned with the broader energy transition championed by Saudi Arabia internationally, creates new industrial capabilities and employment, and positions the Kingdom as a technology leader in emissions management.
Current Landscape
Saudi Arabia’s CCUS capabilities are anchored by several operational and planned projects. Saudi Aramco has operated a carbon capture facility at the Hawiyah gas plant since 2015, capturing approximately 500,000 tonnes of CO2 per year and injecting it into the Uthmaniyah oil reservoir for enhanced oil recovery. This project, among the largest in the Middle East, demonstrated the technical feasibility of large-scale CO2 capture and geological storage in the Kingdom.
The Jubail CCS hub represents the next phase of scale-up. This industrial cluster approach co-locates multiple CO2 emitters — refineries, petrochemical plants, power generation facilities — with shared capture, transport, and storage infrastructure. The hub model reduces per-tonne costs by achieving economies of scale in pipeline transport and geological storage.
Aramco has also invested in direct air capture technology through partnerships with international companies. While direct air capture remains expensive relative to point-source capture, the technology represents a potential long-term pathway to negative emissions that could further strengthen the case for continued hydrocarbon production.
The Kingdom’s circular carbon economy framework — endorsed by the G20 during Saudi Arabia’s 2020 presidency — provides the conceptual architecture for the CCUS strategy. This framework categorises carbon management into four pathways: reduce, reuse, recycle, and remove. CCUS technologies span multiple pathways, capturing CO2 for geological storage (remove), enhanced oil recovery (reuse), or conversion into chemicals and building materials (recycle).
Key Players and Stakeholders
Saudi Aramco leads the technical development and deployment of CCUS projects. The company’s research and development centres have invested significantly in capture technologies, storage characterisation, and CO2 utilisation pathways. Aramco holds numerous patents related to carbon management technologies.
The Ministry of Energy and the Ministry of Environment, Water, and Agriculture jointly oversee the policy framework for CCUS, including regulatory approvals for geological storage, emissions reporting requirements, and international climate commitments.
SABIC contributes through its involvement in CO2 utilisation — converting captured CO2 into chemical products such as methanol, urea, and polycarbonates. SABIC’s operations in Jubail already utilise CO2 as a chemical feedstock in certain processes.
The King Abdullah Petroleum Studies and Research Centre (KAPSARC) provides analytical and policy research on carbon management economics, supporting evidence-based decision-making for CCUS investment.
International technology partners — including Mitsubishi Heavy Industries, Linde, Air Liquide, and Carbon Clean — supply capture technology, equipment, and engineering services. The Saudi market represents a significant growth opportunity for these companies given the scale of the Kingdom’s CCUS ambitions.
Growth Drivers
Protecting hydrocarbon demand. The existential driver for Saudi CCUS investment is the protection of long-term demand for its oil and gas resources. If CCUS can demonstrably reduce the lifecycle emissions of hydrocarbons to levels competitive with alternative energy sources, it weakens the argument for rapid fossil fuel phase-out and preserves the value of the Kingdom’s reserves.
Blue hydrogen enablement. Blue hydrogen — produced from natural gas with CCS — is a cornerstone of Saudi Arabia’s hydrogen export strategy. Without CCUS, there is no blue hydrogen. The scale of the Kingdom’s hydrogen ambitions therefore directly drives CCUS investment.
Enhanced oil recovery. CO2 injection for enhanced oil recovery serves a dual purpose: it increases crude oil production from mature fields while permanently sequestering CO2 underground. This alignment of economic and environmental incentives provides a near-term business case for CCUS investment.
International climate commitments. Saudi Arabia’s net-zero by 2060 pledge requires significant emissions reductions across the economy. CCUS is expected to contribute a substantial share of the required abatement, particularly in hard-to-decarbonise industrial sectors.
Carbon border adjustment mechanisms. The European Union’s Carbon Border Adjustment Mechanism and similar policies under development in other jurisdictions create financial penalties for carbon-intensive imports. CCUS deployment allows Saudi exporters to reduce the embedded carbon content of their products, maintaining market access and competitiveness.
Challenges
Cost reduction. Carbon capture remains expensive, with costs typically ranging from $40 to over $100 per tonne of CO2 depending on the source concentration, technology, and scale. While costs are declining, achieving the cost reductions necessary to make CCUS economically viable without subsidies at the scale Saudi Arabia envisions remains a significant challenge.
Storage capacity characterisation. Geological storage of CO2 requires detailed characterisation of subsurface formations to ensure permanent containment. While Saudi Arabia’s geology — including depleted oil reservoirs, deep saline aquifers, and basalt formations — offers substantial theoretical storage capacity, proving this capacity to the standards required for permanent storage is a multi-year, capital-intensive process.
Regulatory framework development. Comprehensive regulation of CO2 transport, injection, storage, and long-term liability is still evolving in Saudi Arabia. Clear regulatory frameworks are necessary to attract private investment, ensure environmental integrity, and establish monitoring and verification standards.
Public perception and international scrutiny. CCUS attracts criticism from some environmental advocates who view it as a mechanism to extend the life of fossil fuels rather than a genuine climate solution. This perception risk could affect the social licence for CCUS projects and the international credibility of Saudi Arabia’s climate commitments.
Scale-up risk. Moving from current capture volumes of less than one million tonnes per year to the 44 million tonne target by 2035 represents a roughly forty-fold increase. Scale-up of this magnitude involves significant execution risk, including engineering challenges, supply chain constraints, and workforce development requirements.
Investment Implications
CCUS investment in Saudi Arabia creates opportunities across a broad technology and services value chain. Companies providing capture equipment, solvents, membranes, compression systems, and monitoring technology are positioned to benefit from the Kingdom’s ambitious deployment targets.
Engineering, procurement, and construction firms with CCUS expertise face growing demand as the project pipeline expands from pilot to commercial scale. The hub model in Jubail implies large-scale infrastructure projects — shared pipelines, compression stations, and injection facilities — that generate substantial EPC contract opportunities.
For oilfield services companies, CO2 injection for enhanced oil recovery represents a growing service line. The dual benefit of increased oil production and carbon sequestration creates a compelling business case that supports sustained investment.
Investors should also monitor the development of carbon credit and offset markets in Saudi Arabia. If the Kingdom establishes a domestic carbon pricing mechanism or trading scheme, CCUS projects would generate monetisable credits that improve project economics.
The linkage between CCUS and blue hydrogen means that hydrogen market developments directly influence the investment case for CCUS. Investors in either space should evaluate both sectors together as interconnected components of the low-carbon hydrocarbon strategy.
Outlook
Saudi Arabia’s CCUS programme is positioned at the intersection of climate policy, energy economics, and industrial strategy. The Kingdom is betting that technology-enabled carbon management can preserve the role of hydrocarbons in the global energy system while meeting increasingly stringent emissions targets.
The next five years will be critical in demonstrating whether CCUS can be deployed at the scale and cost necessary to fulfil this ambition. The Jubail hub development, the ramp-up of blue hydrogen production, and the expansion of CO2 enhanced oil recovery will provide tangible evidence of the programme’s viability.
If Saudi Arabia succeeds in demonstrating large-scale, cost-effective CCUS, the implications extend far beyond the Kingdom. It would validate a pathway for continued hydrocarbon use in a net-zero world and position Saudi Arabia as a technology and service provider for CCUS globally. If the programme falls short of its targets — due to cost overruns, technical challenges, or inadequate storage capacity — it would strengthen the argument for accelerated transition away from hydrocarbons and diminish the long-term value of the Kingdom’s reserves.
The stakes could scarcely be higher, and the outcome will significantly influence the trajectory of both Saudi Arabia’s economy and the global energy transition.
