The Danish Case
In Denmark, the government launched an exceptionally ambitious incentive scheme for CCS, selecting ten projects for public subsidies. The goal was to transform the country into a European hub for CO₂ capture and storage, leveraging its offshore infrastructure and deep-rooted energy industry. The political signal was unmistakable: CCS was to be a cornerstone of the Danish climate transition.
And yet, eight out of the ten selected projects have withdrawn. The common denominator was significant financial uncertainty across the entire decarbonization value chain. Consequently, it proved impossible to build a solid investment case on incentives perceived as fragile and politically volatile.
The Swedish Case
Weeks later, the Municipality of Växjö in Sweden announced it was pausing its Bio-CCS initiative at the Sandviksverket biomass plant. This project was particularly significant, as capturing biogenic CO₂ from a district heating plant would have contributed to “negative emissions”—a critical component in pathways toward climate neutrality.
The reasons for the halt almost perfectly mirror the Danish experience: high economic risk, uncertainty surrounding support mechanisms, and market conditions that are not yet mature enough to justify a Final Investment Decision (FID). The technology was ready, and the political will—at least on paper—was there. But the regulatory and financial framework buckled when the moment of truth arrived.
A Challenge That Is No Longer Technological
These two cases should not be dismissed as simple hiccups; they are diagnostic red flags. CCS is consistently identified as an essential technology for reaching net-zero—cited by the IPCC, European industrial masterplans, and national strategies alike. However, the gap between strategic rhetoric and industrial execution remains vast.
This begs the question: why? Operating CCS plants already exist, engineering expertise is well-established, and supply chains are forming. The bottleneck today lies in the structure and stability of incentives, and their failure to align with investment horizons in heavy industry, which rarely span less than ten to fifteen years.
The Clash of Time Horizons
One of the most overlooked aspects of the CCS debate is the temporal disconnect between political cycles and industrial investment cycles. A government may launch an incentive program, select projects, and tout ambitious targets, only to shift the goalposts, revise support levels, or fail to renew expiring mechanisms within a single legislative term.
For industrial or financial investors, this volatility is often a dealbreaker. CCS projects require massive upfront capital—for feasibility studies, front-end engineering design (FEED), and the development of transport and storage infrastructure—with returns spread over decades. If the regulatory framework is perceived as intermittent, the risk-adjusted return simply cannot compete with alternative capital allocations.
This is not a market failure in the traditional sense. Rather, it is a policy failure: an inability to create support instruments durable and credible enough to structurally alter the economic calculus for private investors.
Value Chain Fragility
A second structural insight from the Danish and Swedish cases is that fragility affects the entire value chain, not just individual projects. Capturing CO₂ is only the first step. It must then be transported via pipeline or ship to geological storage sites, injected underground, and monitored indefinitely. Does a mechanism currently exist to remunerate this activity in a stable manner?
In Europe, this infrastructure is still largely under construction. Regional hubs are emerging in the North Sea (such as Norway’s Northern Lights project) and parts of the Baltic. However, coverage remains fragmented, and the availability of transport and storage capacity at accessible prices remains a critical variable.
When an industrial emitter evaluates a CCS investment, they assess the entire cost stack and risk profile of the chain. If any link falters—from transport pricing to storage availability—the entire house of cards collapses.
Implications for European Policy
The European Union has designated CCS as a strategic technology under the Net-Zero Industry Act and has set storage capacity targets for 2030. However, these targets risk remaining “paper goals” unless they are backed by tools that mitigate perceived investor risk.
Several shifts are necessary. First, the longevity of support mechanisms: multi-decade schemes with scheduled, non-arbitrary reviews are needed to provide certainty. Second, specific de-risking instruments, starting with public guarantees that can lower the cost of capital for pioneer projects.
Finally, and perhaps most urgently, there must be direct public investment in shared transport and storage infrastructure. Just as with the power grid or gas networks, certain components of the CCS chain are unlikely to be developed by private actors without a public-sector backbone.
Given its leading role in the industrial energy transition, CCS will not remain in this state of limbo between promise and implementation forever. But the speed at which it matures depends on the regulatory and financial choices made in the coming years. Every project that withdraws is a signal that the system has yet to find its equilibrium. Ignoring these signals would be a costly mistake.
