Which, of course, doesn't negate that it may be used for other
applications as your example.

Large central-station generating units are very large, very complex and
very expensive and the payback of a little extra efficiency is
sufficiently high they can afford the added complexity in handling H.

For other uses, the handling issues can easily be prohibitive.
