I am not a big fan of hydrogen just for hydrogen's sake. Too many problems in some applications. But this system looks like it might be a nice system integration model. Someone must have done the performance/cost trade-off for the H2 storage/fuel cell subsystem against straight battery storage and seen some advantages to the melding of the two. I'd like to dig in more and see what their design criteria was and the cost/performance trade-offs.

It's interesting to me at present as I am working on a concept for an independent mid term (1-2 week) power source for an Emergency Operations Center for our City/County. I may end up contacting Toshiba.
