We model the economics of powering an oil platform from shore, using cheap renewable power instead of traditional gas turbines. This can lower upstream CO2 emissions by 5-15kg/bbl, or on average, around 70%; for a base case cost of $50-100/ton.
Our numbers are derived from reviewing technical papers, plus ten prior projects (mostly in Norway), which are tabulated in the data-file, including capex figures (in $M and $/W) where disclosed.
The costs of CO2 abatement can be flexed by varying inputs to the model, such as project size, gas prices, power prices and carbon prices.
