Plants capture more CO2 than expected – experts respond

Laura Goodall posted in on October 14th, 2014.

A study published in the journal Proceedings of the National Academy of Sciences has suggested that current climate models have underestimated how much carbon dioxide plants absorb, therefore overstating how much of the gas is actually in the atmosphere. The scientists say current forecasts don’t account for the slow diffusion of atmospheric carbon dioxide inside plant leaves, […]

Scientists claim success in burying carbon – experts respond

John Kerr posted in on December 13th, 2011.

Australian scientists are claiming success following completion of a New Zealand-backed pilot carbon capture and storage project that saw thousands of tonnes of carbon-rich gas pumped underground. However, New Zealand experts are divided on the usefulness of the geoengineering solution to cut growing emissions both in New Zealand and overseas. The CO2CRC Otway project pumped […]

GNS scientist Brad Field on the promise of carbon capture and storage

Peter Griffin posted in on September 25th, 2009.

Stuart Haszeldine’s article in Science this week identifies the main issues regarding the implementation of capture and underground storage of carbon dioxide: the technology exists, but how readily can it be up-scaled, and will there be enough economic and political push to deploy it extensively by 2020? The CCS market is an artificial one, where […]

British Government’s plan for carbon capture & storage

Peter Griffin posted in on April 24th, 2009.

Britain’s energy secretary, Ed Miliband has announced that no new coal-fired power station will now get government consent in the United Kingdom, without it having equipment to capture and bury at least 25% of emissions now and 100% by 2025 when CCS technology is expected to be technically and commercially proven. Debate about the suitability […]
