Owain Tucker describes the physics, the engineering and some of the challenges behind a technology that could dramatically reduce carbon-dioxide emissions

Is carbon capture and storage (CCS) the technology that could be key to slowing climate change or an expensive diversion? Few people are aware that we already have the technology to remove most of the carbon dioxide emissions from fossil fuelled power and industry. This same technology is needed to deliver the negative emissions called for in almost all integrated assessment models. Collectively, this rather prosaic and unexciting technology is termed Carbon Capture and Storage, CCS—or Bio-energy with CCS, BECCS, when delivering negative emissions. This short book describes the technology, and takes a brief look at some of the reasons why society is not yet urgently reaching for it.
