Here is a link to a Chinese company we worked with on switchgrass developmen about 10 years ago. They were the first to develop clean coal technology in household boilers in China with the help of a Norwegian scientist.

The founder couldn't sleep at night as he wanted to diversify his business from only coal as he knew the devastating impacts of coal. They now have a line of small biomass briquette boilers suitable for heating, cooking and domestic hot water as well as clean coal boilers. Our goal was to grow switchgrass and briquette it as a coal replacement in China. The problem we encountered is there is not so much productive marginal land in China. Marginal land in China is completely unproductive land like desert or salt laden lands. I said switchgrass is drought tolerant but not desert tolerant. They ended up starting the biomass briquette business with wood residues and crop residues.
I still think making densified grasses into briquettes could be developed into a useful fuel in some countries. We have a new publication out on switchgrass in North America if anyone is interested.

Dear Frank
My goodness, you got that
right:
>Money will continue to
be wasted on foolish projects until this is approached as a
’science’ project and looking at the fuel is the ONLY
next step.
Characterising the fuel is
important, and there are two additional needs: the
technologies that creatively burn it controllably and well,
then the test methods that give relevant,
correctly calculated comparisons so we know whether or not
we are making progress.
This is exactly what happened with
the TLUD gasifiers, and the crossdraft coal gasifiers. I was
not involved in the former but I can vouch for the processes
used to perfect
the latter.
