No. CCS relies on deep geological formations (e.g. depleted oil/gas reservoirs, saline aquifers). These have securely stored fluids for millions of years. The EU’s CCS Directive and EEA guidance (updated July 2024 by DNV) enforce stringent siting, monitoring, and closure rules. Long-term leakage is essentially zero—validated globally in mature operations.

Absolutely proven. CCS has been deployed commercially for over two decades in sectors like natural gas processing and enhanced oil recovery. The US alone stores over 100 MtCO₂ annually via 20+ projects, with 200 additional permits pending.

Yes. The European Commission estimates that by 2050, Europe will need to store at least 300 to 450 million tonnes of CO₂ every year to meet its climate targets. That’s a massive scale-up from today’s storage capacity, which is under 5 million tonnes per year.

The good news is that geological storage capacity in Europe is not a limiting factor—there’s enough space underground to store hundreds of years’ worth of emissions.
With regulatory backing, industrial investment, and emerging infrastructure like CO₂ transport networks, scaling up to meet Europe’s annual storage targets is entirely achievable.

Danube Carbon Storage is building the long-term storage infrastructure now to help deliver on this mission.

Yes. In the EU:
• Permits adhere to the CCS Directive, with oversight by Member States.
• The Net-Zero Industry Act and EU quotas ensure compliance
• The Industrial Carbon Management Strategy and Commission guidance foster safe, rapid deployment. Ultimately, public authorities—not Danube Carbon Storage—grant licenses and monitor performance.
