Chevron's carbon capture and storage (CCS) facility at its Gorgon LNG plant in Australia underperformed in 2021 with 2.26 million tons of carbon dioxide injected underground, well below its annual capacity of 4 million tons per year of CO2.

For comparison, annual CO2 emissions by Australia is 494.2 million tons per year

Chevron's CCS project has been working well below its annual capacity since it was launched in August 2019, three years after the Gorgon LNG project began operations, as the company grappled with new technology and technical problems.

Sand issues

One of the major issues has been the presence of sand that has clogged parts of the CCS project. This prompted Chevron to significantly reduce the amount of CO2 injected underground.
