Electrolyser Modelling

[MohammedAbiAfthab]

@MAA129:  Ok, I got your message with some characteristics.

Please see below an example TIMES specification in a VEDA Subres template:



Here, the efficiency parameters for 2015 should be closely following those you stated:

66 % efficiency for 100 %, 60 % efficiency for 80 % load, 55% efficiency for 60 % load, 50 % efficiency for 40 % load.

The efficiency loss (measured by increase in specific consumption) at 40% load would be 32%, in accordance with your values (66%/50% = 1.32), as specified by ACT_LOSPL(2015,FX). NCAP_OLIFE gives the operating life at full load (in years), which may lead to a longer technical life if the device is used at partial loads.

Thank you very much @Antti-L. I will try this way of modelling and see the results.

Hi Antti-L,

I checked this modelling using a simple test electroyser. However, my parameter values are a little different what you have modelled. But the ACT_LOSPL and ACT_MINLD are not being considered by the model in the calculation. Despite I have given an input load less than the ACT_MINLD (70 %)  to the electrolyser, the electrolyser is working with full efficiency. Could you have a look at my file? I have uploaded the baseyear template and the LST file. I can see that in the LST file, those two parameters are not appearing in the equations.
