🗞️ Driving the news: Governments and industries are accelerating the development of offshore carbon capture and storage (CCS) projects, aiming to store captured emissions in depleted marine oil and gas wells or subsea aquifers
• Major initiatives are underway in the North Sea, Gulf of Mexico, and Southeast Asia, supported by public and private investment
• Advocates call it a key tool for decarbonising “hard-to-abate” sectors such as steel, cement, and chemicals — but concerns are rising over environmental risks, cost, and long-term effectiveness
🔭 The context: Offshore CCS leverages the fossil fuel sector's existing infrastructure, repurposing platforms and pipelines to store CO₂ below the seabed
• Although over 70 CCS facilities operate globally, most are onshore; only a few offshore projects currently exist in countries like Norway, Brazil, and China
• Yet dozens of new multi-billion-dollar proposals are in development, backed by climate strategies such as the EU's target to store 50 million metric tons of CO₂ annually by 2030
🌍 Why it matters for the planet: While CCS could support decarbonisation of sectors lacking viable alternatives, the technology is resource-intensive and comes with environmental risks, including potential leakage, ocean acidification, and harm to marine ecosystems
• Its close ties to the fossil fuel industry raise concerns that it may prolong hydrocarbon use rather than curtail it
• Critics argue that the focus on CCS diverts critical funding away from proven renewable energy solutions
⏭️ What's next: The next few years will be critical for offshore CCS as large-scale projects like Northern Lights (Norway) and Greensand (Denmark) ramp up
• Key challenges ahead include scaling infrastructure, ensuring stringent monitoring, and developing independent regulatory frameworks
• Whether CCS can deliver durable climate gains or merely serve as a costly stopgap remains under scrutiny, especially amid growing calls for transparent data and robust environmental safeguards
💬 One quote: “There’s a high risk of being cavalier with CO₂ … It just seems like a series of triage and bandages that are trying to extend the life of a problem rather than solving it.” – Grant Hauber, Institute for Energy Economics and Financial Analysis
📈 One stat: The EU estimates it will need 7,300 kilometers of CO₂ pipelines by 2030 to meet its offshore storage goals — at an estimated cost of €19.5 billion ($22.6 billion)
