sions from the flood of new coal-fired power stations planned over the
next decades, especially in India and China”. But the very convenience of
CCS working should put people on their guard against wishful thinking.
CCS technologies have been tried before. Capture technologies have
been used in the making of chemicals and fertilizers, and to take the CO 2
out of natural gas. There has also been some limited CCS useage in the oil
and gas sector. CO 2 is being re-injected into natural gas fields in the North
Sea and onshore in Algeria. It is also being piped from a coal gasification
plant in North Dakota in the US to a Saskatchewan oilfield in Canada to
increase oil recovery there.
The novel and daunting aspect of CCS will be to combine capture,
transport and storage across the entire power sector. One UK expert
likened it, in the British context, to “carrying out the whole desulphuriza-
