CCS Commercialisation Competition

"Ferrybridge Key Facts
.Project partners: Scottish and Southern Energy PLC, Doosan Babcock and Vattenfall
.Technology: solvent (amine) based post combustion capture
.Fuel: coal /small proportion of biomass
.Capacity: extracts up to 100 tonnes CO2 / day from a power station flue gas stream equivalent to 5MW electrical power. Total power station output = 2000MW electrical.
.Efficiency: around 90% of CO2 removed from flue gas
.Project budget: more than £20 million
.Public funding: more than £6 million from DECC, TSB and Northern Way"

Therefore approximately 111 tonnes of CO2 / day is emitted by generating 5MWe, of which 90% can be collected (100 tonnes of CO2 / day)

Now look at page 11 the presentation below

This document gives the typical solvent regeneration energy for Monoethanolamine (MEA), which is 3.6 to 3.9 GJ/tonne CO2

Therefore for the CCPilot100+ this will be approximately 375 GJ per day if 100 tonnes of CO2 is captured in a 24 hour period.

The electrical energy generated during this period is 432 GJ (5MWe for 24 * 60 * 60 seconds)

Therefore the MEA solvent regeneration energy expressed as a percentage of the electrical energy is around 86%

I thought the carbon capture process was supposed to be more efficient than this?

Have I got the calculation wrong? I presume much more efficient methods are in the pipeline.
