The conclusion is that for the central case
by 2040 846 million tonnes would be
transported for an average cost of £1.71/
tonne. Due to timing of investments and
design differences the other cases in this
instance have a lower cost per tonne, but
the table shows that different discount rates
have more influence on costs per tonne than
do the differences between scenarios.
If not otherwise noted the costs per tonne
refer to the 2040 volumes and cumulative
costs at 11% discount using £1.70/tonne.
Analysis of the most favourable standalone
case of a near coastal source using just
Ravenspurn North for storage from the
same date as the central scenario shows
the following comparison:

An inland site has additional pipeline costs
and future business case analysis may show
revenue requirement differences which make
the standalone case less attractive, but the
first emitter to commit to CO2 capture and
storage does face higher costs whether
or not their pipeline becomes part of an
evolving network. There is therefore a need
to address the problem of network initiation.
