The prime climate objective is not to end the use of fossil fuels.The prime objective is to develop and deploy 100% CCS in time to cap cumulative emissions of carbon at a safe level.
CO2 EOR can be seen as a stage in a path from zero CO2 capture to 100% CCS.It is a move in the right direction from where we are now – emitting 100% of fossil carbon to atmosphere.The technologies that CO2 EOR helps to develop can readily be adapted to get higher fractions of CO2 stored.
Climate Effects Linked to Cumulative GHG Emissions
The Prime Minister, Mr David Cameron – Jan 2014: “I support the carbon budgeting process and the Climate Change Act, which I think is a good framework. My nervousness about being too frank about the future is
Committee on Climate Change – Oct 2009: “In our December 2008 report, we set out a range of scenarios to meet our 80% emissions reduction target in 2050. The common theme running through these scenarios was the need for early decarbonisation of the power sector..”
simply down to the issue about carbon capture and storage and the role that gas will play in future….. If you have fixed a decarbonisation target and said you are going to take carbon out of electricity generation before you know whether you can get carbon capture and storage in place, I think you would be making a huge mistake”http://data.parliament.uk/writtenevidence/WrittenEvi dence.svc/EvidenceHtml/5219

Up to 10 million tonnes of carbon dioxide (CO2 ) emissions could be captured from the Peterhead Power Station in Aberdeenshire, Scotland and then transported by pipeline and stored, approximately 100km offshore in the depleted Goldeneye gas reservoir, more than 2km under the North Sea.

(May not be entirely realistic since better to constrain wind than nuclear, also may want some fossil running as reserve in addition to pumped storage, but indicates the level of disruption – note also that this is a period of high demand.)

• First serious UK natural gas CCS project proposal 9 years ago • Now CCS is the priority for UK energy policy, not the fuel (so gas
and biomass supported, as well as coal).• Support mechanism in place (FiT with CfD) on same basis as
renewables and for electricity supplied, not CO2 price for CO2 avoided compared to the default option, i.e. natural gas combined cycle (NGCC) without capture.
• Plant level emission performance standard at NGCC level is a backstop, not the main CCS (non-)delivery driver.
• All new power plants >300MW, including natural gas, must be capture ready.
• Natural gas is (the only?) low-CAPEX, low-carbon technology, but reducing capital costs further is more important than efficiency in some market situations, including for CO2 for EOR in North America.
• Range of technology options being developed.
