Resumen de: US20260028730A1

Conventional control schemes for electrolyzers focus on maximizing electrical efficiency, which describes the relationship between the electrical energy consumed and the gas produced by the electrolyzer. However, the cost associated with high electrical efficiency may be unnecessarily expensive. In one embodiment presented herein, a model is used to determine the cost (or profit) associated with a gas produced by the electrolyzer at each of a plurality of operating conditions. The control system can select the operating condition to use based on which operating condition is associated with the lowest cost (or highest profit), even though that operating condition may not be associated with the highest electrical efficiency.
