This is a set of conceptual models representing electrolysis, the conversion of electrical energy and water into hydrogen gas. The interaction between solar photovoltaic, energy storage (battery) and electrolyzer is captured in green_hydrogen_Battery.slx. Parameters in the model are set to capture a consistent physical behaviour but are not related to any specific commercial electrolyzer in particular. Run Start_Up.m, prior to simulating the model. ------------------------------------------------------------------------ The implementation of the electrolyzer (Simscape language) is propietary of the author and MathWorks and hence not disclosed in this submission. MathWorks offers licenses and Consulting services. Under a consulting framework, collaboration may be established to build a tailored electrolysis unit. Any feedback would be really appreciated.
