hey everyone,

I would to model hydrogen system using Oemof containing an electrollyzer, fuel cell and storage. I see in the documentation in order to work with OffsetTransformer (to model an electrolysis process with different efficiencies in part load condi!on.) we have to define the P_out_min and the and the P_out_max to calculate coefficients of input-output line equation.

However what I’am actually aiming to do is a dispatch op!misa!on based on costs using the investment mode. so my question it’s possible to use OffsetTransformer and considering the investment mode.

Besides to the OffsetTransformer there is the PiecewiseLinearTransformer component. for example in order to model an electrolyzer I need to define the in_breakpoints which basically depend on the nominal_value (max electrical input power off the electrolyzer). Again The goal consists of determining the optimal capacity using the investment mode and that’s makes me confused,

I’am grateful for any help.
