Figures based on Markal10 documentation, Energy process and infrastructure, page 14
Figures for refineries derived from Markal documentation. Low cost figures taken from 'standard refinery' (Capex £m(2000)1.686/PJ and Opex £m(2000)0.1594/PJ) high cost figures taken from 'high limit refinery' (Capex £m(2000)3.519/PJ and Opex £m(2000)0.1883/PJ). The "default" point is the 35th centile between these low and the high costs.
Based on the fact that the UK currently has 9 refineries producing approximately 90 million tonnes of petroleum per year, We assume a refinery size capable of dealing with 10 Mtoe/y. Working through the conversions, this appears to work out to 418.7 PJ/a, or ~13.3GW. We have simplified this to 13GW.
Assume a refinery has a 30 year life. Treat this as meaning (1/30) of refineries need to be replaced each year.
Issues and questions for stakeholders
- OPEX costs may be a touch high. Other sources on the net quote figures for refining cost of c. $0.30 - 0.60 per gallon (business.whatitcosts.com/refine-oil.htm). Markal is slightly above that range.
- Is it reasonable to assume refineries have an economic life of 30 years?
