My batteries last between 10 and 20 years depending on whether they are flooded cells or AGM type. Energy volumetric density is about the same as high pressure hydrogen when you add in the compressor and cylinders. And if you are using low pressure storage you don't have near the energy density as the batts. Hydrolyser/fuel cell is about the same size or larger than a rack mounted switch mode rectifier. Plus you lose energy in the conversion process, more loss than the charge and discharge cycles of batts.
