❓ FAQ

Q: Is CCS safe? Could CO₂ leak underground?

Yes, CCS is completely safe.No, CO₂ cannot leak from underground storage.

🪨 CCS stores CO₂ deep underground in geological formations like depleted oil & gas reservoirs and saline aquifers—the same formations that have safely contained natural fluids for millions of years.

🇪🇺 In the EU, CCS is regulated by the CCS Directive and the European Environment Agency’s latest guidance (updated July 2024 by DNV). These rules ensure careful siting, continuous monitoring, and secure closure.

🌍 Around the world, long-running CCS projects confirm that with proper regulation and design, long-term leakage is essentially zero. The science—and the track record—prove it works.

Q: Is the technology proven or experimental?

Absolutely proven.

CCS is a well-established technology that has been used commercially for over 20 years—especially in industries like 🌍 natural gas processing and 🛢️ enhanced oil recovery.

🇺🇸 In the United States alone, more than 100 million tonnes of CO₂ are securely stored every year across 20+ operational projects, with over 200 additional permits already in the pipeline 📈.

This is not an experiment—it’s real, working, and scaling globally 🌐.

Q: Is it scalable? Can we reach the levels Europe needs?

✅ Yes, absolutely.

📊 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.

Q: Is CCS regulated—and who ensures it’s done responsibly?

Yes—CCS is strictly regulated.

In the 🇪🇺 European Union, CCS projects follow a clear legal and regulatory framework to ensure safety, transparency, and accountability:

🔒 Permits are granted under the EU CCS Directive, with enforcement and oversight by Member State authorities.

📜 The Net-Zero Industry Act and EU-wide storage quotas make compliance mandatory.

⚙️ The Industrial Carbon Management Strategy and latest European Commission guidance support the safe and accelerated deployment of CCS.

🧭 Importantly, it’s independent public authorities—not Danube Carbon Storage—who issue licenses and monitor site performance over the long term.
