    Good day Sir/Mdm,

    May I ask questions regarding LEAP-NEMO and energy storage modelling. From what I understand is that energy storage needs LEAP optimisation to be operating in order for it to run in the results. LEAP optimisation would require economic/cost data for it to operate to get the lowest cost.

    1) Is a way for me to simulate just the technical parameters (no cost data) of energy storage? Based on my results, the electricity hourly generation for all sources are working but energy storage is always zero (hourly power generation MW). I hope I could get insights for alternative ways I could carry out the energy storage simulations. Please advice me on what I could do as I may have limited/incorrect understanding on how LEAP-NEMO operates with energy storage.

    2) However, if the technical parameters of energy storage can function without cost data, is there any parameters I could adjust such as imports/exports, charge/discharging time, lowering demand, increasing supply, to make the storage operate?

    3) How do I obtain the hourly electricity demand (time slices) graph in results? I am trying to plot my own stacked graph of matching the hourly power generation by sources with the hourly demand throughout the 92 time slices.

    4) Is there a way to model carbon capture (CCUS) in LEAP?

    I am looking forward to hearing your reply and I really appreciate the help.

    Thank you very much.

    Hi Malcolm -

    1. Your understanding is correct: since the optimization capabilities offered by NEMO are predicated on least-cost principles, you would need economic inputs in order to perform any type of optimization calculation, including those involving energy storage. You may of course assign values of zero to all costs to ensure that your model runs, but the results wouldn't be very meaningful.
    2. You may still specify exogenous imports and exports, minimum and maximum utilizations, and adjust energy demands (requirements), which will cause your storage processes to operate differently in different scenarios. But the solution returned by NEMO to LEAP is still a least-cost solution, abiding by the constraints of the optimization problem.
    3. I believe what you're looking for is Transformation:Power Requirements, which you may display by time slice on the x-axis. You may also look at Transformation:Power Generation (or Transformation:Energy Generation) to see how your processes are being dispatched to meet those requirements.
    4. Yes, but there are probably a few different strategies depending on your specific needs. I'd suggest starting a dedicated thread on this topic, if there are no other related questions on the LEAP forum.
