China's first offshore CO2 injection platform completed

🗞️ Driving the news: China has completed the main structure of its first offshore carbon-injection project, with the central platform at the Dongfang 1-1 gas field entering commissioning
• The facility is designed to capture and purify CO₂ produced alongside natural gas before compressing and injecting it into underground formations

🔭 The context: The project combines carbon storage with enhanced gas recovery: injecting CO₂ is intended to improve production from harder-to-reach reserves while permanently storing the captured gas
• Dongfang 1-1, which began production in 2003, is now a mature field with declining gas output and rising CO₂ content, creating conditions for the technology

🌍 Why it matters for the planet: Permanent underground CO₂ storage could reduce the emissions intensity of existing offshore gas production if the captured CO₂ remains securely stored
• However, the project is also designed to extend natural-gas production, so its overall climate benefit depends on the amount of CO₂ actually stored and the emissions associated with continued fossil-fuel extraction

⏭️ What’s next: The platform is entering commissioning, with full operation expected to enable more than 1 million tonnes of CO₂ injection annually
• The project could provide a model for deploying offshore carbon capture and storage at other high-CO₂ gas fields in China

📈 One stat: >1 million tonnes of CO₂ per year — the project’s planned permanent underground storage capacity once fully operational
