Aquaterra Energy has started fabricating its first Recoverable Abandonment Frame (RAF) system for the Northern Endurance Partnership. This technology helps secure legacy oil and gas wells to ensure the long-term integrity of offshore CO2 storage sites in the UK. The RAF system aims to lower well abandonment costs by up to 20 million pounds per well and reduce remediation timelines by 50%. It is a critical component for the East Coast Cluster, which plans to store 4 million metric tons of CO2 annually starting in 2028.

Aquaterra is building a system to fix old oil wells so they don't leak CO2. They claim it saves 20 million pounds per well. Worth watching to see if those cost savings actually hit the balance sheet during the NEP rollout.

The 50 percent reduction in timelines is the more interesting part. If they can actually speed up remediation, the 2028 target for 4 million tons looks more realistic. Do we know how many legacy wells are actually flagged as high risk in these specific basins?

Using a recoverable frame instead of permanent plugs makes sense for flexibility, but I wonder about the long term maintenance costs. It is one thing to install it, another to ensure it stays viable for decades under pressure.

This is a practical example of how technical risk affects climate finance. Investors won't touch these clusters if the liability for legacy leaks is too high. Solving the abandonment problem is a prerequisite for the insurance markets to support CCS.
