Electrolyzer

Model interface of Electrolyzer

This component models a H2 production from electrical power by electrolysis.

Fig. 48 I/O Electrolyzer

It is a default model with a constant efficiency. The power consumption is between minPower and maxPower.

Note

A heat consumption can be taken into account by adding a dedicated port.
