Carbon Capture Edges Forward Despite Cost Challenge

How EU carbon market rules now treat captured emissions

The European Union has changed how its carbon trading system handles captured CO₂. Operators no longer need to surrender allowances for emissions they capture and store permanently or bind into products. This matters because it reduces the compliance cost for heavy industry, though deployment remains slow due to high capital requirements and infrastructure gaps.

The EU Emissions Trading System has operated since 2005 as a cap-and-trade mechanism. It covers power generation and energy-intensive sectors including cement, steel, and chemicals. Companies must surrender one allowance for every tonne of CO₂ they emit. The system sets an annual emissions cap that falls over time, creating scarcity and therefore price signals for carbon reduction.

Recent reforms under the Fit for 55 package have tightened these rules considerably. The 2024 changes lowered the emissions cap and accelerated annual reductions to meet the EU’s target of cutting net emissions by at least 55% from 1990 levels by 2030. Consequently, allowance prices have risen, making carbon capture technologies more commercially relevant for sectors that cannot easily switch to low-carbon alternatives.

What the amended directive actually says

Directive (EU) 2023/959 clarifies the treatment of captured carbon after nearly two decades of regulatory uncertainty. Operators avoid surrendering allowances when they capture CO₂ and either store it permanently in geological formations or bind it chemically into products during normal use. This covers all transport methods including ships and trucks, not just pipelines.

The rules now explicitly address carbon capture and utilization alongside storage. For CCU applications to qualify, they must deliver genuine net emissions reductions. This means the carbon must remain bound for the product’s intended lifespan. Short-lived uses that release CO₂ quickly do not qualify for exemption.

This policy shift carries significant commercial weight for manufacturing and processing industries. A cement plant capturing 500,000 tonnes annually would previously have needed allowances worth roughly €28 million at current prices of around €56 per tonne. Under the amended rules, that cost disappears if the carbon is stored or bound appropriately. However, the capital cost of capture equipment and ongoing operational expenses remain substantial barriers.

Financial support mechanisms now available

The EU Innovation Fund supports commercial deployment of low-carbon technologies using revenues from allowance auctions. It holds a budget of €40 billion through 2030, specifically targeting projects that can scale beyond demonstration phase. Carbon capture projects compete for grants alongside renewable energy, energy storage, and other climate technologies.

In 2024 alone, the ETS raised €183.6 billion through allowance auctions. All revenue must go toward climate action under EU rules. Member states receive most auction proceeds and typically channel funding into domestic energy efficiency programs, renewable subsidies, or industrial decarbonization support. Some countries offer additional incentives like CO₂ price guarantees or contracts for difference that bridge the gap between capture costs and allowance prices.

The Connecting Europe Facility provides separate funding for cross-border CO₂ transport infrastructure. This matters because geological storage sites are concentrated in specific regions, notably the North Sea basin. Industrial clusters in landlocked areas need pipeline or shipping connections to access storage capacity. Nevertheless, infrastructure development lags behind policy ambitions, creating a practical bottleneck for many potential projects.

Why commercial deployment remains limited in 2025

Despite these incentives, large-scale carbon capture deployment across EU industry remains rare. Most operating facilities are demonstration projects or serve specific industrial processes where captured CO₂ has immediate commercial value. The fundamental problem is cost. Capture equipment requires major capital investment, and operating expenses including energy consumption are substantial.

Current allowance prices around €56 per tonne fall short of the level needed to justify capture investments in most applications. Industry estimates suggest prices above €80 per tonne are typically required for capture to compete with simply purchasing allowances and continuing to emit. This gap means projects depend heavily on grants or national subsidies to proceed. Furthermore, the interaction between ETS rules and member state support schemes creates complexity that slows decision-making.

Several countries have introduced domestic carbon price guarantees or capacity mechanisms to de-risk investments. These schemes promise minimum prices or revenue floors for captured carbon. However, their design varies significantly between member states, creating uneven conditions across the single market. A steel producer in Germany faces different financial incentives than a comparable facility in Poland or Spain, even though both operate under the same ETS framework.

Infrastructure constraints compound these challenges. Many industrial sites lack access to suitable storage locations or transport networks. Building new pipelines requires regulatory approvals, land rights, and coordination across multiple jurisdictions. Ship-based transport offers more flexibility but adds logistical complexity and cost. As a result, even projects with solid economics struggle to reach final investment decision.

Industrial sectors facing different pressures

Cement production represents perhaps the most compelling case for carbon capture. Process emissions from calcination account for roughly 60% of total CO₂ from cement plants, independent of energy source. These emissions cannot be eliminated through electrification or fuel switching alone. Consequently, cement manufacturers face a stark choice between capture technology and purchasing ever-more-expensive allowances as the cap tightens.

Steel production using blast furnaces faces similar constraints. While hydrogen-based direct reduction offers a lower-carbon alternative for new facilities, converting existing assets requires enormous capital. For plants with decades of remaining operational life, carbon capture may offer a more economically viable path to compliance. Several demonstration projects in Germany, Belgium, and the Netherlands are testing capture systems integrated with blast furnaces.

Chemical manufacturing presents a more varied picture. Some processes produce relatively pure CO₂ streams that are easier and cheaper to capture. Others involve complex mixtures requiring expensive separation. The economics therefore vary considerably depending on specific production routes and plant configurations. In addition, some chemical products naturally incorporate carbon, potentially qualifying as CCU under the amended rules if the binding proves durable.

Refining and petrochemicals face particular scrutiny given their association with fossil fuels. However, these industries argue they provide essential products for which demand will continue during the energy transition. Carbon capture offers a pathway to reduce emissions intensity while maintaining production. Critics counter that subsidizing fossil-related industries through ETS exemptions undermines the transition to renewable alternatives.

How free allocation interacts with capture incentives

The ETS continues to provide free allowances to certain industries to prevent carbon leakage, where companies might relocate production outside the EU to avoid compliance costs. This allocation gradually phases out between 2026 and 2030, conditional on facilities submitting energy efficiency improvements and carbon neutrality plans. The Carbon Border Adjustment Mechanism increasingly replaces free allocation by imposing equivalent carbon costs on imports.

For facilities with carbon capture, this creates a dual incentive. They avoid surrendering allowances for captured emissions while potentially retaining free allocations for remaining emissions during the transition period. However, free allocation calculations consider historical emissions, not current performance. This means installations that invest early in capture may not immediately benefit from the full value of emission reductions in their allocation calculations.

Member states can also provide additional support using ETS revenues, capped at 25% of their auction proceeds. This funding typically targets electricity-intensive industries or specific decarbonization investments. The interaction between EU-level rules and national schemes creates both opportunities and complexity. Companies must navigate multiple support mechanisms, each with different eligibility criteria, application processes, and timing.

What UK businesses should understand about this

UK companies no longer participate in the EU ETS following Brexit, instead operating under the UK Emissions Trading Scheme. However, these EU developments carry commercial significance for several reasons. Firstly, UK exporters to EU markets compete with European producers who benefit from these carbon capture incentives. This affects price competitiveness in carbon-intensive products like steel, cement, and chemicals.

Secondly, the UK government watches EU policy closely when designing domestic climate measures. Similar treatment of captured carbon exists in UK ETS rules, though the specific implementation details differ. Understanding how EU incentives operate helps UK businesses anticipate potential domestic policy directions. Moreover, some UK companies operate facilities in both jurisdictions and must navigate both regulatory frameworks.

Cross-border infrastructure projects may eventually connect UK industrial sites to European CO₂ transport networks and storage facilities. The North Sea holds significant geological storage capacity in depleted oil and gas fields, accessible from both UK and EU industrial regions. Consequently, regulatory alignment on captured carbon treatment facilitates potential future collaboration on shared infrastructure.

Supply chain implications also merit attention. UK manufacturers sourcing materials from EU producers should consider how carbon costs affect input prices. As EU facilities install capture technology and reduce allowance obligations, their cost structures may shift. This could influence the competitive position of UK companies using imported intermediate goods versus those relying on domestic supply.

Essential points about EU carbon capture policy

• The EU ETS now exempts permanently stored or bound CO₂ from allowance surrender requirements under Directive (EU) 2023/959, effective since 2023.
• Current allowance prices around €56 per tonne remain below the €80-plus typically needed to justify capture investments without additional subsidies.
• The Innovation Fund provides €40 billion through 2030 for low-carbon technology commercialization, including carbon capture projects competing for grants.
• Free allowances for heavy industry phase out between 2026 and 2030, conditional on facilities submitting carbon neutrality and energy efficiency plans.
• Infrastructure bottlenecks including limited CO₂ transport networks and storage access constrain deployment despite favorable policy treatment.
• Member states can provide supplementary support using up to 25% of their ETS auction revenues, creating varied national incentive landscapes.
• The Carbon Border Adjustment Mechanism replaces free allocation by imposing equivalent carbon costs on imports, affecting trade competitiveness.

Strategic considerations for emissions-intensive operations

Companies in covered sectors should evaluate their long-term emissions trajectory against the declining ETS cap and rising allowance costs. The business case for carbon capture depends on multiple variables including facility location, emissions volume, access to storage or utilization options, and availability of capital support. Furthermore, regulatory certainty matters enormously for investments with 20-year payback periods. Policy stability and clear rules on monitoring, reporting, and verification affect investment risk.

Early movers may gain competitive advantages if they secure favorable grant terms or infrastructure access before capacity constraints bind. However, technology costs typically fall as deployment scales, creating a potential disadvantage for pioneers. This tension requires careful financial modeling that accounts for both first-mover benefits and wait-and-see alternatives. In addition, operational flexibility has value when multiple decarbonization pathways exist with uncertain relative economics.

Integration with broader site decarbonization strategies matters significantly. Carbon capture works best alongside energy efficiency improvements, renewable electricity adoption, and fuel switching where feasible. A holistic site plan identifies the lowest-cost combination of measures to achieve required emissions reductions. Carbon reporting compliance programs help businesses structure this analysis and track progress against regulatory requirements.

Supply chain positioning represents another strategic dimension. As major customers face their own Scope 3 emissions pressures, they increasingly favor suppliers with lower carbon intensity. Being among the first in your sector to deploy capture technology can strengthen customer relationships and potentially command price premiums. However, this requires clear communication about emissions reductions and credible verification through recognized standards.
