Bio-CCS at Scale: Sweden Backs 5.75 Million Tonnes of Biogenic CO2 Storage With SEK 9.3 Billion

The Swedish Energy Agency has awarded SEK 9.3 billion (€840 million) to capture and permanently store 5.75 million tonnes of biogenic CO2 under Sweden’s second reverse auction for negative emissions, according to Carbon Pulse. The announcement came on Friday. For developers, investors and buyers following carbon removal, it is a large public commitment to bio-CCS (bioenergy with carbon capture and storage) in a market the agency itself describes as early stage.

Three companies received funding: Renova, SYSAV and Öresundskraft. Together they were granted SEK 9.3 billion for the capture and permanent storage of biogenic carbon dioxide, per the Swedish Energy Agency. The volume attached to the award is 5.75 million tonnes.

The agency says the projects met all requirements in the call for proposals. It also says they were assessed as having viable plans for capture, transport and geological storage of the CO2. All three links of that chain had to be credible for a project to qualify.

How the Reverse Auction Works

Support was allocated through a reverse auction. Applicants compete to deliver negative emissions at the lowest support level per tonne of carbon dioxide. The lowest bid for a tonne wins, rather than the highest price paid.

The agency argues this directs public money to the projects that deliver the greatest climate benefit. Carl Mikael Strauss, Head of Unit at the agency, said that interest in the second auction shows companies are willing to develop bio-CCS in Sweden, despite the market still being at an early stage of development.

A Thin Field: Three Applicants

The second call for proposals closed on 13 August 2026. Only three companies applied, and all three received support. The source material does not say whether any bid was rejected, so the award should be read as a full uptake of a small field rather than a selection among many competitors.

That matters for how the competitive element is read. A reverse auction produces the strongest price discipline when bids outnumber the funding available. With three applicants, the process confirmed that the proposals were viable, but the material gives no indication of how much price competition took place.

The Policy Logic Behind Bio-CCS

The agency has been tasked since 2021 with designing and implementing a support scheme for negative emissions through bio-CCS. This is the second auction under that scheme. Sweden’s stated target is net-zero emissions by 2045 and negative emissions thereafter.

The agency frames the approach in two parts. Sweden needs both major emission reductions and additional measures, and bio-CCS is described as a complementary measure. It has the potential to store large volumes of biogenic CO2 each year and to strengthen the competitiveness of Swedish industry.

Caroline Asserup, Director General of the agency, called the award “a step forward on Sweden’s path towards achieving its climate targets”. She added that the support builds capacity and creates business opportunities in a new industrial sector.

Why Biogenic CO2 Matters for Removal Markets

Biogenic CO2 comes from biological sources, so capturing and permanently storing it can result in net removal from the atmosphere. That is why the Swedish scheme speaks of negative emissions rather than only avoided emissions. Permanence is a central requirement: the agency’s assessment explicitly covered geological storage.

For buyers of carbon removal, the award is a signal about where publicly funded supply is being built. Public support of this scale can bring large capture projects to the point of investment. The source material does not say how the stored tonnes will be accounted for or whether any will be sold as credits, so no conclusion on that can be drawn here.

Implications for Buyers, Developers and Investors

For developers, the result shows that a state-run reverse auction can underwrite a full capture, transport and storage chain. The agency’s evaluation criteria, viable plans for each step, are a useful reference for what public funders look for.

For investors, the figures set a scale marker: 5.75 million tonnes and SEK 9.3 billion under a single auction round. The agency itself calls the market early stage, which suggests execution risk remains until the projects are built and storing CO2.

For buyers, the open question is how this supply relates to voluntary and compliance demand. The material does not address eligibility, crediting or the timing of storage, and these details will determine whether the volumes become visible in carbon markets.

What to Watch

Three points deserve attention. First, the conditions and timeline attached to the support, which the available material does not detail. Second, whether the projects reach construction and begin storing CO2. Third, whether Sweden runs further auctions and attracts more than three applicants, which would test the price competition that a reverse auction is meant to create.

Until those points are clear, the award is best read as a funding decision rather than delivered removals. Its significance lies in the size of the commitment and in the policy design, a competitive auction for permanent storage of biogenic CO2, now in its second round.
