I recently read an article about the CO2 injection and storage project at Gorgon on Barrow Island, offshore Western Australia.
The gas in the Gorgon field contains around 14% CO2, which is removed prior to being condensed into a liquid (LNG) and re-injected into a suitable storage reservoir 2km beneath the island. According to operator Chevron this will reduce the project GHG emissions by around 40% over the life of the project.
I wondered whether this figure seemed low, but then began to think about the source of the other 60% (and what may/may not have been factored into the calculation) … Thoughts?
I’ll follow up with my list in Part 2, next week.
