Billions of dollars have been committed to carbon capture technologies as governments and industries race towards net zero. Once celebrated as a breakthrough solution for hard-to-abate sectors, Carbon Capture and Storage is now facing mounting scrutiny over its cost, performance and long-term viability. As projects expand across the globe, the industry finds itself at a defining moment that could reshape the future of industrial decarbonisation.
Carbon Capture at a Turning Point
The global energy transition has never been a straightforward journey. While renewable energy continues to transform electricity generation and electric vehicles steadily reshape transportation, some of the world’s largest industrial sectors remain stubbornly difficult to decarbonise. Steel plants, cement factories, chemical manufacturers, refineries and fertiliser producers continue to generate enormous volumes of carbon dioxide through processes that cannot simply be replaced by solar panels or wind turbines. For these industries, Carbon Capture and Storage (CCS) emerged as a technology that promised to bridge the gap between today’s carbon-intensive operations and tomorrow’s low-carbon economy. Only a few years ago, carbon capture was widely regarded as one of the most promising climate technologies of the decade. Governments incorporated CCS into national net-zero strategies, multinational energy companies announced ambitious investment plans and financial institutions began supporting large-scale projects aimed at reducing industrial emissions. The technology was increasingly presented not as an optional solution but as a critical component of achieving global climate goals. International agencies, including the International Energy Agency (IEA), repeatedly highlighted CCS as an important tool for reducing emissions from sectors where electrification alone would be insufficient.
That confidence triggered an unprecedented wave of investment. Across Europe, North America, the Middle East and Asia, governments introduced generous incentives, tax credits and funding programmes to accelerate deployment. Energy companies viewed CCS as an opportunity to lower the carbon intensity of existing operations while continuing to meet growing global energy demand. Heavy industries embraced the technology as one of the few commercially available options capable of addressing unavoidable process emissions. Collectively, these developments transformed carbon capture from a niche engineering concept into one of the world’s fastest-growing climate investment sectors.
Today, however, the optimism surrounding CCS is becoming increasingly measured. While new projects continue to be announced, growing evidence suggests that the technology faces significant technical and economic hurdles. Several flagship facilities have struggled to achieve expected capture rates, project costs have risen sharply and commercial deployment has progressed more slowly than many industry forecasts anticipated. Rather than questioning whether carbon capture works in principle, policymakers and investors are beginning to ask whether it can deliver the scale, affordability and reliability required to support a global net-zero transition. This shift in sentiment does not necessarily signal the decline of carbon capture. Instead, it marks the beginning of a more realistic conversation about where the technology delivers genuine value, where its limitations become apparent and how it should fit within broader decarbonisation strategies. For energy professionals, industrial leaders and governments, these questions have become increasingly important as climate targets move closer and investment decisions become more consequential.
Why Heavy Industry Needs More Than Renewable Energy
Much of the success achieved in reducing emissions over the past decade has come from replacing fossil fuel-based electricity generation with renewable energy. Solar and wind power have become significantly more affordable, battery storage continues to improve and electrification is expanding across transport and buildings. Yet these advances solve only part of the climate challenge. Industrial manufacturing presents a fundamentally different problem. Cement production, for example, releases carbon dioxide not only through the combustion of fuels but also through the chemical conversion of limestone into clinker, a reaction that inherently produces CO₂. Even if every kiln operated entirely on renewable electricity, these process emissions would still occur. Similar challenges exist in steel production, petrochemical manufacturing, fertiliser production and certain mining operations, where carbon emissions are embedded within the production process itself rather than the energy source.
This reality explains why CCS has attracted such widespread attention. Instead of attempting to eliminate emissions before they are produced, carbon capture focuses on preventing them from entering the atmosphere. Carbon dioxide is separated from industrial exhaust gases, compressed into a dense fluid and transported through dedicated infrastructure to secure geological formations thousands of metres below ground. These underground reservoirs, often depleted oil and gas fields or deep saline aquifers, provide long-term storage intended to isolate carbon dioxide for centuries.
Alongside conventional CCS, Direct Air Capture (DAC) has also emerged as a complementary technology. Unlike traditional capture systems installed at industrial facilities, DAC removes carbon dioxide directly from ambient air. Although this approach offers the possibility of reducing historical emissions, it remains considerably more energy-intensive and expensive because atmospheric carbon dioxide concentrations are far lower than those found in industrial exhaust streams. Consequently, most experts view DAC as a long-term solution for achieving negative emissions rather than a replacement for conventional carbon capture in heavy industry. The strategic importance of CCS therefore lies not in replacing renewable energy but in addressing emissions that currently have few commercially viable alternatives. For sectors responsible for producing the materials that underpin modern economies, including concrete, steel, chemicals and fuels, carbon capture has become one of the few technologies capable of supporting meaningful emissions reductions while maintaining industrial productivity.
The Global Investment Boom
Confidence in carbon capture has translated into unprecedented financial commitments over the past five years. Governments have increasingly recognised that achieving climate targets will require more than renewable electricity alone, prompting major public investments in carbon management infrastructure. The United Kingdom has committed up to $29 billion over the next 25 years to develop industrial carbon capture and hydrogen clusters, positioning the country as a global leader in low-carbon manufacturing. Germany has introduced a $5.7 billion Carbon Contracts for Difference programme, designed to accelerate industrial decarbonisation by supporting carbon capture and utilisation projects. Denmark has signed a $2.55 billion agreement supporting Aalborg Portland’s carbon capture initiative, one of Europe’s largest industrial CCS projects, aimed at significantly reducing emissions from cement production.
Across the Atlantic, the United States has strengthened its support through expanded tax incentives under the Inflation Reduction Act, encouraging private investment in capture, transportation and geological storage infrastructure. These incentives have significantly improved the commercial attractiveness of carbon capture projects, particularly across the refining, petrochemical and natural gas sectors.
Major Global Carbon Capture Investments
| Country/Region | Investment | Strategic Objective |
| United Kingdom | Up to $29 billion | Develop industrial CCUS clusters and low-carbon hydrogen production |
| Germany | $5.7 billion | Carbon Contracts for Difference supporting industrial CCS |
| Denmark | $2.55 billion | Large-scale cement decarbonisation through CCS |
| United States | Multi-billion-dollar tax incentives | Accelerate commercial CCS deployment through the Inflation Reduction Act |
| European Union | Innovation Fund support | Scale industrial decarbonisation and carbon management technologies |
Private industry has mirrored this momentum. Companies including ExxonMobil, Shell, Chevron, TotalEnergies, Equinor and Occidental have all announced ambitious carbon management strategies involving billions of dollars in planned investment. For these organisations, carbon capture is not simply a climate initiative. It has become an increasingly important business strategy designed to reduce operational emissions, maintain investor confidence and prepare for tightening carbon regulations across global markets. Industry forecasts reflected this optimism. The World Economic Forum projected that global carbon capture capacity could increase fourfold before the end of this decade, supported by hundreds of proposed projects across energy, manufacturing and heavy industry. Investors increasingly viewed CCS as one of the defining climate technologies of the coming decades, capable of creating new commercial opportunities while supporting national emissions targets.
Yet despite this extraordinary level of financial commitment, the industry’s rapid expansion has exposed challenges that many early forecasts underestimated. Technical complexity, rising capital costs and inconsistent operational performance are beginning to reshape expectations, raising important questions about whether carbon capture can scale quickly enough to justify the enormous investments now flowing into the sector.
A Strategic Opportunity for the UAE and the Gulf
Few regions are better positioned to shape the future of carbon capture than the Gulf. As economies that combine large-scale hydrocarbon production with ambitious sustainability agendas, GCC nations are uniquely placed to integrate carbon management into their long-term economic strategies. The United Arab Emirates has already established itself as one of the region’s most proactive investors in industrial decarbonisation. Alongside landmark renewable energy developments and its Net Zero by 2050 Strategic Initiative, the country is expanding carbon capture as part of a broader approach to reducing emissions while maintaining energy security and industrial competitiveness.
ADNOC continues to invest in expanding carbon capture capacity across its operations, recognising that lower-carbon energy production will play an increasingly important role in international markets. Carbon management also complements the UAE’s growing investments in hydrogen, artificial intelligence and advanced manufacturing, creating opportunities to position the country as a global hub for low-carbon industrial innovation. Neighbouring Saudi Arabia and Qatar are pursuing similar ambitions through large-scale carbon management programmes linked to petrochemicals, natural gas and industrial manufacturing. Rather than viewing CCS solely as an environmental obligation, Gulf economies increasingly see it as a strategic investment capable of protecting export competitiveness as carbon regulations become stricter across Europe and other major trading partners.
For the UAE in particular, success in carbon capture could strengthen its position as a leader in both conventional and low-carbon energy. However, achieving that ambition will ultimately depend not on the number of projects announced, but on whether those projects consistently deliver the environmental and economic outcomes that governments, industries and investors now expect.
When Reality Meets Ambition: Why the Cracks Are Beginning to Show
Despite the remarkable growth in investment and political support, Carbon Capture and Storage is now entering its most challenging phase. The debate is no longer centred on whether the technology is scientifically feasible. Instead, it focuses on whether CCS can consistently deliver the environmental outcomes, economic viability and operational reliability that governments and industries have promised. As more commercial-scale facilities begin operating around the world, their performance is providing valuable lessons that are reshaping expectations across the energy sector. The optimism surrounding CCS was built on the assumption that most facilities would capture close to 90 percent of their targeted emissions while operating efficiently over decades. That benchmark became widely accepted across policy discussions, investment models and corporate sustainability strategies. However, operational data from several projects tells a more complicated story. Independent assessments indicate that many facilities have struggled to achieve their intended capture rates, while some have experienced prolonged operational interruptions, technical failures or higher-than-anticipated maintenance requirements.
One of the most widely discussed assessments came from the Institute for Energy Economics and Financial Analysis (IEEFA), which reviewed thirteen operating carbon capture projects across different regions and industrial sectors. The study found that the majority of these facilities failed to consistently achieve their designed capture capacity, with several operating well below expected performance levels. Although individual project outcomes varied considerably depending on technology, location and industrial application, the findings reinforced concerns that commercial deployment remains significantly more complex than early projections suggested. The Global CCS Institute estimates that around fifty commercial CCS facilities were operational worldwide by the end of 2024. While this represents substantial growth compared to a decade ago, their combined capture capacity still accounts for only a tiny fraction of global carbon dioxide emissions. Against annual global emissions exceeding 37 billion tonnes, existing CCS facilities currently capture only a very small percentage of the carbon released each year. This disparity highlights the enormous scale required if carbon capture is to play a meaningful role in achieving international climate targets. For policymakers, these figures illustrate an important reality. Carbon capture is progressing, but not yet at the pace required to transform global industrial emissions.
The Economics Are Becoming Harder to Ignore
Beyond technical performance, economics has become the industry’s greatest challenge. Carbon capture remains one of the most capital-intensive decarbonisation technologies currently available, requiring substantial investment not only in capture equipment but also in transport infrastructure, compression facilities and long-term geological storage. Unlike renewable energy projects, where costs have fallen dramatically over the past two decades through manufacturing scale and technological improvements, CCS has yet to experience a comparable reduction in overall project costs. Every industrial facility presents unique engineering challenges, making standardisation difficult and limiting opportunities to rapidly reduce capital expenditure.
For many companies, the financial burden extends well beyond construction. Operating carbon capture systems requires significant amounts of energy, increasing fuel consumption and reducing overall plant efficiency. This phenomenon, commonly referred to as the “energy penalty”, means facilities often require additional power simply to operate the capture equipment itself. As energy prices fluctuate, these operational costs can become increasingly difficult to justify without government support.
Recent estimates illustrate the magnitude of this challenge. In the United States, integrating carbon capture into natural gas power plants is estimated to increase electricity generation costs by approximately $20 to $30 per megawatt-hour, potentially doubling the cost of electricity in certain scenarios. Across Europe, research by Agora Industry and the Oeko-Institute suggests that capturing, transporting and permanently storing carbon dioxide could cost between $170 and $340 per tonne, significantly exceeding many earlier projections. Such figures have intensified discussions around the long-term affordability of CCS, particularly in industries operating within highly competitive international markets. For governments providing financial incentives, rising project costs raise another important question. How long should public funding continue supporting technologies that remain commercially dependent on subsidies?
Carbon Capture Performance and Cost Indicators
| Indicator | Current Status | Industry Implication |
| Commercial CCS facilities worldwide | Around 50 | Growing deployment but limited global coverage |
| Share of annual global emissions captured | Approximately 0.1% | Current impact remains relatively small |
| Typical industrial capture target | Around 90% | Benchmark often used in project design |
| European estimated CCS cost | $170-$340 per tonne | Higher than many earlier forecasts |
| Additional cost for U.S. gas power generation | $20-$30 per MWh | Increased electricity production costs |
| Average project development timeline | 5-10 years | Long lead times before climate benefits are realised |
The Greenwashing Debate Continues
Perhaps no aspect of carbon capture has generated more controversy than its relationship with the fossil fuel industry. Environmental organisations argue that CCS risks becoming a mechanism that prolongs dependence on oil and natural gas rather than accelerating the transition towards genuinely low-carbon alternatives. Their criticism centres on a straightforward concern. If companies can capture a portion of their emissions, they may have less incentive to fundamentally redesign industrial processes or invest aggressively in renewable technologies. Instead of replacing carbon-intensive infrastructure, carbon capture could enable existing facilities to continue operating for decades with only incremental improvements in emissions performance.
This criticism has become particularly visible in discussions surrounding so-called “low-carbon oil”. Several energy companies have promoted crude oil produced with lower operational emissions through the application of carbon capture technologies. While these initiatives reduce emissions associated with production, critics point out that the overwhelming majority of emissions occur when fuels are ultimately combusted by consumers. From this perspective, reducing production emissions alone does little to address the broader climate challenge associated with continued fossil fuel consumption.
Supporters of CCS strongly reject the characterisation of the technology as greenwashing. They argue that climate policy cannot rely exclusively on ideal future technologies while ignoring the realities of today’s industrial economy. Heavy manufacturing, aviation fuels, shipping, petrochemicals and cement remain essential to global development, and many of these sectors currently lack commercially mature zero-carbon alternatives. Until those alternatives become widely available, carbon capture provides one of the few practical methods for reducing emissions without disrupting economic activity. The truth likely lies somewhere between these opposing viewpoints. Carbon capture is neither a complete climate solution nor an ineffective technology. Its value depends largely on where it is deployed, how effectively it performs and whether it complements broader decarbonisation efforts rather than replacing them.
Why the UAE’s Strategy Looks Different
Unlike regions where carbon capture is viewed primarily as an extension of fossil fuel production, the United Arab Emirates is increasingly integrating CCS into a wider industrial transformation strategy. National initiatives combine renewable energy expansion, hydrogen production, advanced manufacturing, artificial intelligence and carbon management as interconnected components of economic diversification. This broader perspective offers several advantages. Carbon capture can reduce emissions from industries such as cement, steel, aluminium and petrochemicals while renewable electricity continues expanding across the national energy mix. Rather than positioning CCS as an alternative to clean energy, the UAE increasingly presents it as one element within a diversified decarbonisation portfolio.
The country’s substantial geological storage potential also strengthens its long-term prospects. Existing expertise in subsurface engineering developed through decades of oil and gas production provides a technical foundation that relatively few nations possess. Combined with strategic investments in research and innovation, this positions the UAE among the countries most capable of developing commercially viable carbon management infrastructure. Nevertheless, success will depend on transparency, measurable performance and continued technological innovation. Investors and international markets are placing increasing emphasis on independently verified emissions reductions rather than announced project capacity. Future competitiveness will therefore be determined not by ambitious commitments alone, but by demonstrated results.
Carbon capture has undoubtedly progressed from experimental research to commercial reality. Yet the industry’s future will depend less on ambitious announcements and more on its ability to consistently deliver affordable, measurable and scalable emissions reductions. As climate targets become more demanding and investment decisions face greater scrutiny, the coming decade is likely to determine whether CCS evolves into a cornerstone of industrial decarbonisation or settles into a more specialised role within the global energy transition.
The Future of Carbon Capture: From Climate Promise to Strategic Reality
The future of Carbon Capture and Storage will not be determined by political ambition alone. It will depend on whether the technology can prove itself in the real world by consistently delivering emissions reductions at a cost industries are willing to pay. After years of optimism and unprecedented investment, the carbon capture sector has reached a stage where measurable performance matters far more than ambitious announcements. Governments are increasingly demanding accountability for public spending, investors are seeking commercially viable business models and industries are looking for technologies that can support long-term competitiveness rather than short-term compliance.
This shift represents a natural evolution for every emerging climate technology. Solar and wind energy also faced years of scepticism before technological improvements and economies of scale transformed them into some of the world’s most affordable energy sources. Carbon capture may yet follow a similar trajectory, but the pathway is likely to be more complex. Unlike renewable energy technologies that benefit from mass manufacturing, CCS projects are highly customised. Every industrial facility has different operating conditions, emission characteristics and storage requirements, making it far more difficult to standardise equipment or rapidly reduce costs.
Researchers and technology developers are therefore focusing on improving efficiency rather than simply increasing deployment. New generations of capture solvents require less energy during regeneration, advanced membrane technologies promise lower operational costs and artificial intelligence is being used to optimise plant performance by predicting maintenance requirements and improving capture efficiency in real time. Digital monitoring systems are also strengthening confidence in underground storage by providing continuous verification that stored carbon dioxide remains securely contained.
Innovation is equally transforming carbon transportation and storage infrastructure. Instead of constructing isolated projects, several countries are developing regional carbon capture hubs where multiple industries share pipelines, compression facilities and storage reservoirs. This collaborative model reduces costs, improves infrastructure utilisation and allows smaller industrial facilities to participate in carbon capture without building independent storage networks. Such integrated carbon management ecosystems are increasingly viewed as the next phase of commercial CCS development. For the Gulf region, this hub-based approach presents considerable opportunities. Industrial clusters located around ports and energy corridors could support shared carbon infrastructure, lowering costs while creating entirely new value chains centred on carbon management services. This aligns closely with the UAE’s broader ambitions to become a global centre for sustainable industry, advanced manufacturing and climate innovation.
Carbon Capture Will Not Replace Decarbonisation
One of the most important lessons emerging from recent years is that carbon capture should not be viewed as a substitute for emissions reduction. Instead, it functions most effectively as part of a broader decarbonisation strategy. Renewable electricity, electrification, hydrogen, energy efficiency, circular manufacturing and low-carbon materials will continue to deliver the largest share of future emissions reductions across most sectors. Carbon capture becomes particularly valuable where those solutions cannot completely eliminate emissions. Heavy industries such as cement, steel, chemicals and fertilisers remain among the strongest candidates because a significant proportion of their emissions originate from chemical reactions rather than fuel combustion.
This distinction is becoming increasingly important within international climate policy. Rather than promoting CCS across every sector, governments are beginning to prioritise industries where the technology provides genuine environmental value. Such targeted deployment allows public funding to generate greater emissions reductions while avoiding unnecessary investment in applications where cleaner alternatives already exist.
Several industry leaders have echoed this perspective. Discussions at international energy conferences increasingly emphasise that carbon capture should follow, rather than replace, investments in energy efficiency and renewable energy. Where emissions can be avoided through cleaner technologies, those options should generally take precedence. Where emissions remain unavoidable, CCS can provide an additional pathway towards net zero. This more balanced approach is gradually replacing earlier narratives that positioned carbon capture as a universal climate solution. It reflects a growing understanding that no single technology will achieve decarbonisation on its own. Instead, success will depend on combining complementary solutions tailored to the needs of different industries and regions.
Why the UAE Could Become a Global Carbon Management Leader
Among countries investing in carbon capture, the United Arab Emirates occupies a particularly distinctive position. Unlike many nations that are introducing CCS primarily to reduce emissions from existing industries, the UAE is integrating carbon management into a much broader economic transformation strategy. Over the past decade, the country has invested heavily in renewable energy, hydrogen production, artificial intelligence, sustainable finance and advanced industrial manufacturing. Carbon capture complements these initiatives by addressing emissions from sectors that remain essential to economic growth, including energy production, petrochemicals, aluminium, cement and heavy manufacturing.
The UAE also benefits from geological advantages that relatively few countries possess. Decades of experience in oil and gas production have created extensive expertise in subsurface engineering, reservoir management and underground injection technologies. These capabilities provide a strong technical foundation for long-term geological carbon storage while reducing some of the risks associated with developing entirely new infrastructure. Equally important is the country’s emphasis on innovation and international collaboration. Research partnerships between government institutions, universities and industry are accelerating the development of more efficient capture technologies while strengthening regulatory frameworks for monitoring and verification. As international carbon markets continue to evolve, transparency and independently verified emissions reductions are likely to become increasingly valuable competitive advantages.
The UAE’s approach also reflects a broader understanding that sustainability and economic development are no longer opposing objectives. Instead, industrial competitiveness is becoming increasingly linked to carbon performance. Manufacturers capable of producing lower-carbon steel, aluminium, chemicals and energy products are expected to gain stronger access to export markets as carbon border adjustment mechanisms and stricter environmental standards become more widespread. For this reason, carbon capture is not simply an environmental initiative for the Gulf region. It is rapidly becoming an economic strategy designed to secure long-term industrial resilience within an increasingly carbon-conscious global economy.
The Road Ahead
The next decade will likely determine whether Carbon Capture and Storage fulfils its early promise or settles into a more limited supporting role within the global energy transition. Current evidence suggests that both perspectives contain elements of truth. Carbon capture has clearly demonstrated that it can reduce emissions from industrial facilities under appropriate conditions. At the same time, operational experience has highlighted technical complexity, high costs and deployment challenges that cannot be ignored. These realities do not diminish the technology’s potential, but they do reinforce the importance of realistic expectations.
For governments, the priority should now be supporting projects that demonstrate measurable environmental benefits while ensuring public investment delivers long-term value. Transparent reporting, independent verification and rigorous performance standards will become increasingly important as the industry matures. For businesses, success will depend on selecting applications where carbon capture creates genuine competitive advantages rather than relying on it as a universal solution. Companies that combine CCS with renewable energy, digital technologies, energy efficiency and process innovation are likely to achieve stronger commercial and environmental outcomes than those depending on carbon capture alone.
For investors, careful project selection will become critical. Future returns are expected to favour integrated industrial ecosystems supported by shared infrastructure, stable policy frameworks and long-term demand for verified low-carbon products. Above all, the evolution of CCS illustrates an important lesson for the global energy transition. Climate technologies rarely follow a linear path. Initial enthusiasm is often followed by periods of reassessment before genuine commercial maturity emerges. Carbon capture appears to be entering precisely that phase today.
Conclusion
Carbon Capture and Storage is neither the miracle solution its strongest advocates once claimed nor the failed technology portrayed by its harshest critics. It occupies a more nuanced position within the global decarbonisation landscape, offering significant value where emissions cannot easily be eliminated while falling short as a standalone answer to climate change. Its future will depend not on the scale of financial commitments or the number of announcements made, but on measurable performance, continuous innovation and responsible deployment. As industries face increasing pressure to reduce emissions while maintaining economic competitiveness, carbon capture is likely to remain an important part of the climate toolkit, particularly for sectors where alternatives remain limited.
For the United Arab Emirates and the wider Gulf region, this presents both an opportunity and a responsibility. By combining carbon capture with renewable energy, hydrogen, digital innovation and industrial modernisation, the region has the potential to demonstrate how diversified decarbonisation strategies can support sustainable economic growth. Success, however, will require transparency, collaboration and a willingness to adapt as technologies continue to evolve. The carbon capture industry is no longer being judged by its promise. It is now being judged by its performance. Whether it becomes a defining pillar of the net-zero economy or a specialised technology serving selected industries will depend on the decisions made today by governments, businesses and investors alike. What remains certain is that the future of industrial decarbonisation will not be shaped by one solution alone, but by a portfolio of technologies working together to build a cleaner, more resilient and economically sustainable energy future.
