Browse CCS

The Browse Carbon Capture and Storage (CCS) Project is designed to transport, inject, and permanently sequester up to 270 mmscfd (~14,200 tonnes per day) of CO₂ into the Calliance Storage Formation, with an expected average injection rate of 3–4 mtpa. The CO₂ will be sourced from the Browse to NWS Project (EPBC 2018/8319), which is expected to generate approximately 80 million tonnes of reservoir CO₂ over its life (mid-case estimate). The project is designed to capture and store at least 85% of the reservoir CO₂ removed from produced fluids, enabling an estimated net reduction of ~53 million tonnes of GHG emissions (~47%) from the Browse to NWS development. In addition, it will capture and sequester ~9 million tonnes of CO₂ that would otherwise be processed onshore. Infrastructure includes a subsea CO₂ flowline connecting the Browse FPSOs to offshore injection sites, along with 2 to 6 injection wells (up to 7 total wells drilled). CO₂ will be separated from hydrocarbons onboard the FPSOs, dehydrated, compressed, and transported for injection into the storage formation.
