For cooling (datacenters and other) you can chill water when the sun is out. And mostly passively cool the heated water when the sun is down if water is scarce. Plumbing and insulation for cooling reservoirs probably degrades a lot slower than batteries. I'm not sure about chiller plant wear and tear vs battery degradation
