Description

This work focuses on the development of tools and methodologies based on experiments and modeling aiming at exhaustively assessing key performance indicators of alkaline and PEM electrolyzers operating under intermittent conditions. A dynamic lumped performance model of a PEM electrolyzer has been developed in Aspen Plus Dynamics and validated based on real experimental data and dedicated testing protocols from a 55kW system. The characterization of these impacts may lead to the development of mitigation strategies on the design or the operation.
