See http://www.cypenv.org/Files/sequest.htm#Physical%20sequestration - a 
subject I wrote about some time ago. You may also be interested in other 
forms of sequestration on the same page. My guess is that if the UK is 
seeking scientific knowledge, OK. If they are seeking a practical 
solution, I fear that £40M would be better spent on providing better 
health care for their citizens. In particular, I'd like to know how much 
extra energy will need to generated to compress the vast volumes of flue 
gas to the necessary 200-300 bar and then to cool it. Of course, if they 
succeeded to do this on every fossil fuel power station in the UK and 
the EROEI was favourable, it still would tackle only about 20-25% of the 
UK's GHG emissions. The first thing that needs to be done is to stop 
burning fossil fuels, as much as possible, especially natural gas ones:
