Concentrating solar collectors
Concentrating solar collectors

Hospitals commonly use gas-fired steam boiler systems to produce steam for sterilization, then reuse steam to heat water. Alternative options to generate steam include using: (1) Electric steam generators (2) Heat recovery from on-site energy production, and (3) Concentrating solar collectors. Another alternative is chemical sterilization, many forms of which have been or are being developed. The Guidebook will catalog and explain the non-heat technologies and explore alternative methods of generating steam. As new technologies are approved for use in healthcare settings, this Guidebook will promote the technologies and provide guidance for reduction of steam generation.

I don't know of any hospitals in the US who have used solar thermal and liked it. I remember talking with people who experimented with systems during the 70s and found the systems did not work well, or took a... (More)
