tippet combined cycle power plants are close to 58% efficiency, as are microturbines if employed in co-generation systems. Easy proven technology. Fuel Cells are around 60% to 80% tops non proven technology with plenty of snags.

Fuel cells very promising, are several years away IMHO to offer gasturbine reliability and may supplement microturbine plants.

Tip:

Many thanks for the comments and please keep them coming my way. Your expertise in this area is obvious and having your comments (as well as those of others on the thread) are the reasons why I post. If you (or other posters) see any holes in the thinking, it would not hurt feelings at this end in any way. I am a rank amateur in this area.

I do know that the telephone boys hate the rooms full of batteries with a passion and it looks like they are already starting to go the fuel cell route to alleviate this situation. Effectively, it kills two birds with one stone for them and as I noted earlier, the pay-back period is remarkably short. Also, hospitals, airports, and many other types of organizations that view continuous supply of power as imperative, are more than interested. Of course the low emissions are a plus for environmentally sensitive areas.

Fuel cells are not a panacea, but they appear to have reached a level of efficiency where they may be able to provide back-up or remote power at an acceptable all-up cost for certain types of organizations. As noted earlier, I like the folks who can install and integrate this technology.

Best, Earlie
