China installs first offshore carbon injection platform in Hainan's Dongfang 1-1 gas field

China has completed the underwater jacket for its first offshore carbon injection platform in the Dongfang 1-1 gas field off Hainan Province. The 77-meter steel structure weighs nearly 8,000 tonnes and was slid off a barge and set upright at sea on October 4. Once online, the project is designed to store more than 1 million tonnes of CO2 underground each year. The milestone moves carbon capture and storage work offshore, where monitoring and containment are harder than on land. The platform is tied to a gas field, so the CO2 likely comes from gas processing, which gives the project a clear source boundary. The next test is whether injection rates and storage permanence match the design figures.

First offshore carbon injection platform in China, jacket installed in the Dongfang 1-1 field off Hainan. 77 meters, nearly 8,000 tonnes, and over 1 million tonnes CO2 per year once running. Worth watching for how the injection rates hold up over time.

This is one of the few carbon storage projects tied to a gas field, so the accounting will matter. If the CO2 comes from the gas processing itself, that is easier to verify than trying to store someone else's captured emissions. Need to see the measurement and monitoring plan before treating the million tonne figure as delivered.

Good point on the accounting. If the CO2 is separated from produced gas, that's a solid project boundary. If they claim credits for it, the permanence monitoring needs to be public. Otherwise the million tonne number is just a design figure.

The jacket installation is a construction milestone, not storage yet. The real test is injection and containment. Offshore monitoring is expensive and often underreported. I would like to know the reservoir pressure limits and whether they plan to use it for enhanced gas recovery.
