If your local energy storage or grid isn't reliable enough, you can always have a backup diesel generator. Or hydrogen powered generator if you insist this is green. Or some solar cells on your roof. And as much fuel as your risk analysis demands. But the reality is, hospitals can rely on local emergency services for support, and it is likely more cost effective run the risk of spoilage in the rare event of a multi-day power outage than invest in local generation for your refrigeration. My guess would be local equipment failure is more of a risk than a multi-day renewable energy outage, even in latitudes where solar is useless.
