Australia Approves Offshore Carbon Storage Site for Inpex's Ichthys LNG Project

Australia has approved a seabed site off its northern coast where Japan's Inpex plans to store up to 443 million metric tons of carbon dioxide. The project would inject CO2 into the West Peron saline aquifer, about 260 kilometers offshore from Darwin, with the Ichthys liquefied natural gas facility as the first customer. Inpex still needs environmental approvals and other government licenses before injection can start. Supporters, including Australia's resources minister, say carbon capture and storage is needed for hard-to-abate industries. Critics point to risks for dugongs, turtles, and seabirds, plus concern that CCS lets fossil fuel projects keep running. Japan's government calls CCS indispensable for meeting its 2035 and 2040 emission targets, while the IEA projects CCS will deliver less than 5 percent of global emission reductions by 2050.

Australia just approved a seabed site for Inpex to store up to 443 million metric tons of CO2 off Darwin. The main customer is the Ichthys LNG plant, which exports most of its gas to Japan. Worth reading because it shows how CCS is being used to justify new fossil infrastructure, not replace it. The environmental impact assessment is still pending.

The interesting bit for me is the scale. 443 million tons over 35 years is a lot, but the article notes the IEA sees CCS contributing under 5% of emissions cuts by 2050. So this project buys time for one LNG facility while Japan pushes CCS as indispensable. The real question is whether the monitoring can catch leaks before they become a problem.

I want to see the energy balance on this. Injecting CO2 into a saline aquifer takes compressors, pipelines, and ongoing survey vessels. That is a permanent operating load. The article does not give numbers on power draw or leak rates. Before calling this a climate win, I would want the full lifecycle accounting, including methane slip from the gas plant.

The approval only covers the storage site. Inpex still has to finish environmental impact assessments and get other licenses before any injection starts. That is a big distinction. The article frames it as a done deal, but there are several years of regulatory hurdles left. Also, the area overlaps with dugong and turtle habitats, so the EIA is not a formality.

This is a classic policy gap. Japan calls CCS indispensable because it has hard-to-abate steel and refining sectors. But the project is being built in Australia and tied to an LNG export plant. So the accounting question is: who owns the emissions reduction? If the CO2 is stored in Australia, does it count against Japan's target or Australia's? That matters for carbon market integrity.
