You know, the one which strips the CO2 from natural gas, burns the hydrogen, pumps the CO2 into an oil reservoir and thus pumps up more oil?
The calculations which I said I didn\’t trust. Although, I have to admit, I got the reason I didn\’t trust them entirely wrong. Mea Culpa.
In 2005 BP proposed to build a new gas-fired power station at Peterhead, capture the carbon dioxide produced and use it for enhanced oil recovery in the Miller field below the North Sea; this innovative project could have been up and running in 2009. Monbiot is wrong to suggest that the plan would have led to more carbon emissions than savings: between 1.8m and 2m tonnes of carbon dioxide would be injected each year over 20 years, producing an additional 40m-60m barrels of oil. Taking the higher numbers, 40m tonnes of carbon dioxide remains underground, while burning the oil produces approximately 20m tonnes; twice as much carbon dioxide is stored than emitted.
The abandonment of the Miller scheme due to lack of government support means a loss of $6bn in oil revenues and a missed opportunity to take a lead in reducing carbon emissions.

Ah, you see, Jim compared the annual storage of CO2 with the emissions from 20 years of oil pumping.
When, in fact, we should either be comparing the 20 years of CO2 storage with the 20 years of oil pumping, or the annual CO2 storage with the annual oil pumping.
Comparing an annual input with a two decades long output is bound to give us some dodgy numbers.
Now this of course depends upon the Professor above being correct. Perhaps Jim would like to revisit his figures and tell us who is correct here?
