South East Australia Carbon Capture (SEA CCS) – 0.7 mtpa


ExxonMobil – Low Carbon Solutions


Southern Australia

Project Summary:

Equinox has completed the Front End Engineering Design (FEED) for the South East Australia SEA CCS Project. The FEED study includes the onshore gas processing facility design to capture 1.7 million tonnes per year of carbon dioxide for transport and sequestration. The new grassroots facility will capture CO2 from the Longford Gas Plant.

The SEA CCS project also includes a 19-km CO2 export pipeline that connects to offshore sequestration.
