I returned with pleasure to Dave MacKay's blog where almost all his posts are highly pertinent for all, either those whishing to map their professional activity or simply wishing to gen-up on current Climate Change, GW-global warming and energy issues, hopefully all of us. In his post pre-review of the book Challenged by Carbon by Brian Lovell, the blog reader's attention is drawn to the fact that "55 million years ago, an enormous global warming event, raising the temperature of the water at the bottom of the ocean by more than 4 degrees C within roughly 10,000 years occured". I did a rapid Google search and invite readers to do the same.
There is a short history of the big oil companies attitudes from "believing what the rocks say" and they say there is a problem and the business as usual approach and "as a backdrop the war in Iraq
"Yes, some oil companies greened up their public facades in 2003, but have they reverted to business as usual behind the scenes? But what about the rest of the oil industry?"
Quoting MacKay's selection from Lovell since this cannot be over-echoed I believe: "In the second half of the book, Lovell indicates how he hopes the drama will unfold: "government intervention is essential" in relation to the transition to the low-carbon economy; "concerted action" is required from all oil companies; oil companies [and the coal mining and power gen lobby] should turn their remarkable technical skills to a new waste management business: capturing and storing carbon[dioxide CO2], especially carbon [CO2] from coal power stations.
MacKay's figures: "key numbers for carbon capture. A standard unit of carbon capture and storage is "the Sleipner""
1. Norway's implementation of a carbon-emission tax of $55 per tonne of CO2 (which can be compared to today's EU market price of 14.10 euros per tonne),
2. StatoilHydro is storing 1 Mt CO2 per year in the Utsira saline aquifer under the North Sea.
3. A 1-GW coal power station, running all the time, produces roughly 7 Mt CO2 per year. So every 1-GW power station would require roughly 7 Sleipners.
4. The cost to the consumer for electricity from that source might be in the ballpark of an extra 4p per kWh of electricity (similar to the present subsidy for wind power in the UK).
5. The scale of the waste to be stored is worth mentioning. The volume of 7 Mt CO2 (the approximate annual waste from 1 GW coal power station), after it's been compressed to the same density as water, is three times the volume of the great pyramid at Giza.
