Pulsed electrolysis: A breakthrough for energy efficiency?
A recent collaboration between @SmartProSys researchers from the @Max Planck Institute for Dynamics of Complex Technical Systems Magdeburg and experts from @TU Dresden (Chair of Power Electronics and Institute of Control Theory) sheds new light on this topic.
While pulsed electrolysis is often seen as the way to intensify the performance of the electrochemical reactors, this study reveals that the steady-state (DC) operation is always more efficient. ✔ Applying Jensen’s inequality to the nonlinear equivalent circuit model of the water electrolyzer, research proved that the pulsing regime results in higher power requirements than the steady-state (DC) operation.
Although the study focused on water electrolysis, similar outcomes regarding power consumption are expected for other electrochemical reactors.
