More progress I just learned about

It looks like my spec for 50% efficiency in the gas-to-electricity step in Sustainability may have been pessimistic; Fuel Cell Today had an article last year which claimed the possibility of 80% efficiency (see page 4).  (I claim overwork as an excuse.  Yeah, that's it.)

Further, this is not from a SOFC, it's with a turbine-compounded MCFC.  With this sort of efficiency, it would be feasible to dispense with SOFC's entirely.  This is the sort of backup technology which practically guarantees that the concept is viable.  The one element I cannot pin down is cost.

In other news, LiFePO4 cells are heading toward commodity status.

Interesting. The additional good news there is that even if the DCFC tech does not work out for the charcoal processsing step, this technology might be able to step in at 805 efficiency.

Though it makes you wonder what kind of efficiency you could get from a Turbine-DCFC hybrid system, if the DCFCs start out at 80% effifiency on their own...
 
I estimate 85-88%.
 
Oh, how I wish more people would "read" your information...

I DO not read many "blogs" as the VAST majority are "marketing" sca
ms and misinformed self indulgent

rants. But, I always read yours.

Thanks for making "math" & "science" make $ence to the masses.

Happy Holidays!
Chris ; -)
