* CCS Storage

h1 CCS Storage

Costs summary (£ per MtCO2):

| Overall | Low     | High   |
| Capital | 436,133 | 37,224 |

h2 Current Calculator assumptions

* Investment occurs at the same carbon is stored

h2 Cost sources

* High = Oil/Gas field storage (coal) from Markal3.24Doc
* Low = EOR Storage (coal)from Markal3.24Doc

h1 Methodology

I decided to include this as a capital cost in a seperate sheet, although it's a function of energy used rather than a fixed one-off cost before production. In reality, creating the infrastructure will be a one off capital investment and the plant operator would presumably pay a fee to the owner per tonne of carbon stored in order to cover the initial investment. 

High costs were the final vintage in the spreadsheet and low costs were vintage 1 in the spreadsheet from Markal3.24Doc 

The Markal costs of carbon storage are included per PJ. I have interpreted this as meaning cost of storage per PJ of per unit of input fuel and taken a range for the CO2 emissions per TWh of input fuel (from Coal to Gas). High costs are the highest form of storage multiplied by the CO2 intensity of coal and low costs are the cheapest form of storage multiplied by the CO2 intensity of Gas.

h1 Issues, Concerns and Questions

* Very large range

* Should investments be brought forward to reflect a lag between new build and use
