Large tanks of pressurized hydrogen

Greetings list,

I recently ran across this company:

They're marketing a hydrogen fuel cell generator to the telecom market. I know they have a few competitors (Ballard Power Systems?), with more companies in the R&D phase of product development. Would you store a large tank of pressurized hydrogen in a downtown Manhattan office building? Should people legally be allowed to? Does anyone think fuel cell technology is a viable replacement for Diesel generators yet?
