Oceanic Oil and Gas Rigs Could Be Retrofitted to Store CO2 Emissions

in #news5 years ago

A new study from the University of Edinburgh says that North Sea oil and gas rigs could be modified to pump vast quantities of carbon dioxide emissions into rocks below the seabed, combating the climate crisis and potentially saving millions of dollars to decommission them.

The researchers say that refitting old platforms to act as pumping stations for self-contained CO2 storage sites would be 10 times cheaper than decommissioning the structures.

The sites would store emissions generated by natural gas production, and could also be used to lock away CO2 produced by other sources—such as power stations—helping to combat climate change.

Large amounts of natural gas and heat energy can still be extracted from saltwater in exhausted oil and gas fields, the team found. The gas can be used as a fuel or burnt on platforms to generate electricity.

Mixing the saltwater from the oil field with CO2 produced by burning the gas enables it to be injected deep underground for permanent safe storage, researchers say.

That's an awesome idea - just modifying and using the infrastructure that is already there
