Germany advances underground CO₂ storage legislation to boost industrial decarbonisation

The German Bundesrat has officially paved the way for underground carbon dioxide (CO₂) storage within the country, marking a significant legislative step towards industrial decarbonisation. This follows earlier approval by the Bundestag, signaling growing political consensus on the need to adopt Carbon Capture and Storage (CCS) and Carbon Capture and Utilisation (CCU) technologies. The new legal framework permits CO₂ storage predominantly beneath the seabed, excluding protected marine areas and coastal proximity, though it also allows for exceptional instances of onshore storage where federal states legislate accordingly.

This development specifically targets industries historically considered hard to decarbonise, such as cement, lime, and aluminium manufacturing, where CO₂ emissions have been deemed largely unavoidable. The legislation enables the construction of pipeline networks to transport CO₂ from industrial sources for safe sequestration, responding to the need for infrastructure critical to the technology’s deployment.

Stefan Rouenhoff, State Secretary at the Federal Ministry for Economic Affairs and Climate Action, described the new law as a vital building block for Germany’s climate neutrality ambitions and noted that the industry has long awaited such regulatory clarity. The Cabinet’s approval in May 2024 also associated the legal amendments with Germany’s broader Carbon Management Strategy, which includes plans to ratify an amendment to the London Protocol to allow cross-border transportation of CO₂ for offshore storage, a move seen as essential for integrating with international carbon storage efforts.

Germany’s Economy Minister Robert Habeck had earlier outlined these legal changes as part of the country’s roadmap to achieve carbon neutrality by 2045. The approach explicitly excludes coal-fired power plants from using CCS, reflecting a policy decision to phase out reliance on coal while still enabling gas-fired power plants and heavy industry sectors to benefit from CO₂ capture technologies.

While the industrial sector, represented by the German Federation of Industries (BDI), has praised the legislation as crucial for maintaining competitiveness and achieving climate goals, environmental groups have voiced serious concerns. The Bund für Umwelt und Naturschutz Deutschland (BUND) criticised the law for potentially delaying the energy transition by enabling fossil fuel industries to continue emitting CO₂, albeit with costly capture and storage, instead of aggressively reducing emissions at the source. They also raised alarms about the environmental risks, notably threats to potable water safety, and the significant energy demands associated with capturing and compressing CO₂.

The legislation classifies CO₂ storage projects and associated pipeline infrastructure as matters of overriding public interest, facilitating expedited planning and approval procedures, measures vital for the timely scaling of CCS operations. Despite restrictions on onshore storage, the option remains open under strict conditions to individual federal states that choose to adopt their own legal frameworks.

This move complements Germany’s comprehensive strategy to capture hard-to-abate emissions while promoting infrastructure development, including CO₂ pipelines connecting industrial hubs to offshore storage sites in the North Sea. The emphasis on marine-based storage aligns with strong environmental safeguards mandated to protect sensitive oceanic ecosystems.

In sum, Germany’s latest CCS legislation underscores a pragmatic approach to industrial decarbonisation, recognising the technological and infrastructural challenges of eliminating CO₂ emissions from sectors where alternatives remain limited. The policy balances ambitious climate targets with industrial realities but continues to spark debate on the long-term viability and environmental impact of underground carbon storage. As the law moves forward, its success will likely depend on effective regulatory oversight, technological innovation, and ongoing dialogue between industry stakeholders, policymakers, and environmental advocates.
