Cost Optimisation Model for Industrial Technologies (COMIT)
COMIT is a computer program that allows user to find the least cost pathway for meeting the energy needs of UK industry from now until 2050.
Using COMIT
Users set values for the model inputs (for example, fuel prices, technology costs and availability) and the model uses these to calculate the least cost pathway for meeting the UK industry’s energy needs.
The purpose of the model is to support decisions on the decarbonisation of industry. While the model doesn’t necessarily produce pathways that reduce carbon, the user can explore decarbonisation options by setting limits on emissions or providing inputs that encourage the model to favour decarbonisation pathways.
Accessing the code
The COMIT code is available for anyone to view or download in a Github repository. The repository also provides:
- supporting documentation
- an input template
- a comprehensive user guide
Assumptions
A fully populated input template is provided in the GitHub repository. However, where the estimates we have are sensitive we have used dummy values instead. The model will run with these inputs, but they are not reliable estimates of the values required. Where dummy values have been used, this is clearly indicated in the input template, but users will need to supply their own values for these inputs.
Many of the technology assumptions used in COMIT were obtained through research commissioned by DESNZ. The results of this research, at which time the COMIT model was known as the Net Zero Industrial Pathways Model 2 (NZIP2) can be found here:
