Capturing carbon emissions from polluting industries has long been touted as a key way of helping to address climate change, but a new China-US agreement looks like giving much-needed stimulus to development of the technology.

For years, the energy companies have been telling us not to worry. Yes, mounting carbon emissions threaten to heat up the world – but technology, particularly carbon capture and storage (CCS), will come to the rescue.

The trouble is that there’s been plenty of talk about CCS and little action, with few projects being implemented on a large scale.

That could be about to change as China and the US, who have been leading the way on CCS research in recent years, this month signed a raft of agreements on tackling climate change  − with half of them focusing on CCS.

The idea behind CCS is to capture at source the carbon emissions from big polluters, such as power utilities and cement plants, and either pipe the CO2 down into deep storage cavities below the Earth’s surface or to recycle the emissions to be used in the production of biofuels.

Despite various geopolitical rivalries and disputes over trade, China and the US have shown increasing willingness to co-operate when it comes to climate change issues. [Read more →]
