The great merits on low temperature water electrolyzer regarding maturity, large capacity, and cost-effective features have drawn much attention as one of the applications for energy storage systems connected to the renewable energy sources such as the wind and solar. These may provide economic advantages for the management of peaks and valleys in electrical loads as storing to hydrogen as second energy carrier sources, especially in long-term and large-scale(>MW) storage systems.  However, the variable loads arise from the renewable power sources can affect the performance on electrolysis and influence the apparent durability. Here, we will discuss improvements on the low temperature water electrolyzer by the significant interaction between engineering and material science disciplines. By applying porous durable and efficient electrode and a reinforced composite inorganic separator with improved cell and stack designs, the the electrolyzer can overcome few drawbacks such as low current operation and slow response to variable loads. We believe that the improvements of poor kinetic efficiency and mitigation of components degradation would increase the system lifetime, and thus improve the economics of low temperature water electrolysis.
