Abstract: The growing use of renewable energy has increased interest in Power-to-Gas (P2G) systems to produce hydrogen sustainably but traditional approaches to power allocation do not consider the aging of electrolyzer stacks unequally, leading to a shorter operating life and poor use of renewable energy. In this paper, the author suggests an Adaptive Power-to-Gas Conversion with Lifetime-Oriented Stack Coordination framework that dynamically allocates renewable power among several PEM electrolyzed stacks according to the real-time operating hours and stack health indices. The method proposed was tested in a MATLAB/Simulink environment of a 60 kW P2G system with three 20 kW PEM stacks in varying solar and wind generation conditions and over a 24 hours working period. Simulation data shows 95.6% utilization of renewable energy, 73.5% system efficiency, 34.2 kg/day hydrogen production, 51.9% reduction in imbalance in stack loads and an approximate 27.2% increase of stack life vs. equal-load operation. These findings indicate that the framework has the potential to support smart infrastructure of energy which is intelligent, reliable, and sustainable.
