Carbon capture and storage is becoming a green strategy

• By Dr. Richard Aldous, Cooperative Research Centre for Greenhouse Gas Technologies, Australia • With the world closely watching the climate meetings underway in Doha there is renewed interest in the only proven technology that can substantially remove carbon dioxide from the use of fossil fuels; carbon capture and storage (CCS). Notably, much of that renewed interest is from environmental NGOs. This week, the ENGO Network on CCS (an international group of environmental NGOs) released a report on CCS, advocating for its inclusion in the fight against climate change. In October at the National CCS Conference in Perth, the Worldwide Fund for Nature (WWF) advocated deploying CCS on existing power stations. CCS involves capturing millions of tonnes of carbon dioxide a year from gas or coal combustion, then compressing it for injection and permanent storage in deep micro-porous rocks. Whilst CCS has been slow in coming, it could be a valuable tool in the fight against climate change. Like all large resource projects, the lead times for CCS projects can be five to ten years or more, but these large projects offer the potential to keep very large quantities of greenhouse gases out of the atmosphere in one operation. There are eight industrial scale projects in operation around the world now and another eight in construction. There are many more on the drawing board. With its reliance on fossil fuel use and exports, it is not surprising that Australia is one of the world leaders in such a technology. With the world’s largest CCS project in construction at the moment at the Gorgon LNG Project in Western Australia, this is an industry that we will see more of in coming years. Last week, at its annual research symposium, the Australian-based Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC) formally closed off its second major subsurface carbon dioxide storage trial at the Otway Project in Victoria ...Zum vollständigen Artikel
