Aussie students excel at the XPRIZE

The Musk Foundation’s XPRIZE has just announced the winners of the Carbon Removal Student Competition, and three Australian universities have made the cut. The XPRIZE challenges teams from across the world to come up with solutions to the major problems facing our planet. The US$100 Million Carbon Removal prize tackles greenhouse gas emissions, asking teams … Continue reading Aussie students excel at the XPRIZE

The great carbon capture and storage debate: can Santos make it work?

This article on Santos’ carbon capture and storage project first appeared in Cosmos Weekly on 22 October 2021. When Sylvia Little fried her eggs at her Adelaide home one November morning in 1969, she became Santos’s first customer for natural gas from Moomba, 800 kilometres north in the Strzelecki Desert. Today, in subterranean reservoirs depleted … Continue reading The great carbon capture and storage debate: can Santos make it work?

The great carbon capture and storage debate: can Santos make it work?

When Sylvia Little fried her eggs at her Adelaide home one November morning in 1969, she became Santos’s first customer for natural gas from Moomba, 800 kilometres north in the Strzelecki Desert. Today, in subterranean reservoirs depleted by millions like Mrs Little since, the company plans to bury millions of tonnes of carbon dioxide. It … Continue reading The great carbon capture and storage debate: can Santos make it work?

Out of thin air: direct carbon capture is on the horizon

An Australian company could be selling modules that suck carbon dioxide directly from the air as early as next year, but it will be up to the highest bidder to decide what happens to that CO2 once it’s been captured. Melbourne-based Southern Green Gas (SGG) has just announced a partnership with Swiss Re, a multinational … Continue reading Out of thin air: direct carbon capture is on the horizon

Gorgon’s carbon capture target was the largest such project in the world. What does its shortfall mean for the future of CCS?

On Monday, energy company Chevron announced that its Gorgon Liquefied Natural Gas (LNG) project was about to hit a milestone: over two years of operation, nearly five million tonnes of CO2 had been captured and injected underground at Barrow Island, about 1400 km north of Perth off Western Australia’s Pilbara coast. Even by the most … Continue reading Gorgon’s carbon capture target was the largest such project in the world. What does its shortfall mean for the future of CCS?

Gorgon’s carbon capture shortfall

The self-described “world’s largest carbon capture and storage project” hasn’t captured enough carbon to meet its goals. The Gorgon LNG Project, a large-scale gas-mining project off the West Australian coast, has not been able to capture 80% of the carbon dioxide it has emitted over the past five years – a target on which its initial state government … Continue reading Gorgon’s carbon capture shortfall

A new carbon capture catalyst

Chemists have suggested a new method for turning carbon dioxide into methanol using a special catalyst – a technique that could be useful in reducing atmospheric carbon dioxide, transforming it for further use. Key research points Carbon capture and storage could be achieved using carbon dioxide and hydrogen to make methanol, which can be used … Continue reading A new carbon capture catalyst

Carbon storage stars

Mangrove forests could be the key to reducing carbon, according to a new study. Researchers studying mangrove forests on Hainan Island, China, found that having diverse species in these forests enhanced both the quantity of organic matter and storage of carbon in soil.  “Our findings suggest that mangrove forests with greater diversity also have higher … Continue reading Carbon storage stars

How to mop up excess carbon dioxide

Australian researchers say they have raised the bar for carbon dioxide capture and storage with a technology that resembles a sponge filled with tiny magnets and works a bit like an induction cooktop. The absorbent nanocomposite material can be regenerated with remarkable speed and low energy cost – and can even grab CO2 directly from … Continue reading How to mop up excess carbon dioxide
