I am struggling to find a way to model fuel switching and CCS retrofitting for power plants in LEAP. Is there any available method?

Thank you.

You have a few options: you can either modify the characteristics over time of an existing process (which represents a power plant in your transformation module), or, you can displace an existing process with a new one that consumes a different fuel or has different emission factors.

To model CCS, you would likely want to modify the "Avg Environmental Loading" variable for Carbon Dioxide, which you should already have attached to each of the plant's feedstock fuels.You might also consider modifying the plant's Process Efficiency or any of it's cost variables, to represent the different characteristics of CCS plants.

To model fuel switching, you would modify the list of feedstock fuels that a plant consumes (note that you may add others as you would any branch in the tree). Each fuel has "Feedstock Fuel Share" variable, which you may modify as you like.

Good luck,

Taylor

GLPK is free and open-source, and so we can package it together with LEAP. CPLEX is not free, and so you need to obtain it separately from LEAP. But it solves problems much faster than GLPK.
