[Gasification] Re: NREL

Dear list!

It is hard to find clear information on commercial gasification systems, if
any. Lomo Plata in Paraguay was a famous example, but I have been told that
the gasifiers are no longer in use, since low-cost hydropower from the grid
would be available..
It is not that hard to write a proposal were gasification can be economical
feasible, but if your assumptions fail to be true... 

The worldbank report on gasification systems in India gave me some hope, but
I believe it is fair to say that only in certain situations gasification can
compete with low-cost, less-headache and clean hands systems on fossil
fuels. Further I like to mention that an important reason for dissemination
of gasifier systems in India is that there were generous subsidies provided!

I can recommend the following publication about the Indian experience:

"Scaling up Biomass Gasifier Use" by Debyani Ghosh, Ambuj Sagar and V.V.N.
Kishore, November 2004. I found an earlier version on:
http://lnweb18.worldbank.org/ESSD/envext.nsf/46ByDocName/ScalingUpBiomassGas
ifierUseApplicationsBarriersandInterventions/$FILE/ScalingUpBiomassGasifierU
seHarvardTERI2003.pdf

Best regards,

Erik

                         to   Gasification List    from   Lewis L Smith

This thread suddenly made me recall that in December 2005, I scientist whom
I have met and listened to, who is smarter than I am and who has a "tougher"
degree than I do, said over the Internet that there are no commercial
biomass gasification plants in the world. Dead wrong !  

For over three years, I have been searching the Internet for processes which
we could use in Puerto Rico with Napier grass [one of the species called
"elephant grass"]  and corresponding with their inventors and operators.
Although I am traveling and citing from memory, I would venture to assert
that there are over 1,000 under < one mWe in India alone and several dozen >
one mWE throughout the world, including some in Louisiana which have been
gasifying rice husks since the early 1980's.

This is not the first time I have stumbled across such lack of information
in the biomass-gasification community. What gives here ?  It looks like we
have a systemic problem or else, the "friends of petroleum" are more widely
scattered than Murphy's ex-employees !

Cordially. End of message.
