What have we learnt from global CO2 release experiments?

Invited seminar at Geoscience Australia, Canberra (ACT, Australia) where I was a visiting researcher while completing an international placement funded by the UK Carbon Capture and Storage Research Centre (UKCCSRC).

Over the past decade, 42 different CO2 release tests have taken place at 14 different field experiment locations - including GA’s Ginninderra site. The experiments differ in a number of ways, from the geological conditions, surface environments, injection rates and experimental set-up - including the injection and monitoring strategy. However, all of them have released CO2 (free phase or dissolved) into the shallow subsurface to artificially simulate leakage from an engineered CO2 store. Jen has synthesised these experiments and their results with studies at natural analogues, to establish what we have learnt so far about CO2 leakage from this global research effort, common perils and pitfalls, and what knowledge gaps remain that future experiments could seek to address.
