Overwintering is more convenient when it is cut in the fall and just baled
in the spring. We used to cut it in the spring and bale. The problems, more
breakage over winter and the material is so brittle we have to use a swather
to cut it in the spring. The advantages are the fuel is 12-14% moisture so
it require no further drying and its wood like in chemical composition.  The
further north you go the more it is viable. In Manitoba we have a grower of
warm season seed who has 800 acres of grass seed production. He prefers
spring baling to fall baling. It also conserves field moisture in semi-arid
areas by trapping snow. Maybe we could also blend spring and fall harvested
switchgrass. Fall harvest switchgrass can likely work for many commercial
boiler applications so it is an option also.  

Straw combustion will lead to boiler corrosion for most smaller boilers and
also its high chlorine content leads to making it more vulnerable to
creating dioxins. It's just a recipe for headaches for the bioenergy heating
industry. It may work for power plants when co-fired but overall it looks
like grief. Better to use straw for the emerging cellulosic ethanol.
Growing fibre of an improved biomass quality or using crop milling residues
of improved biomass quality is a safer way to succeed in developing the
BIOHEAT industry. Growing switchgrass is as about cheap as harvesting straw
except in the main wheat belt areas.

Roger,

If you use wood as a blend or "pilot" fuel then you can burn most grasses.
Over-wintering does reduce slagging but as the Danes have learned and as we
have learned in Iowa it is not very practical for harvesting, storage and
handling. It's better to find applications and markets where the grass can
do well as is. I thinkfuelprice has driven the interest in burning corn
grain and ag pellets. If the customer will accept straw as a fuel even with
its higher maintenance then the market can grow.

Thanks

Tom

In Eastern Canada, switchgrass will compete with Agri-fibre fuel pellets and
high ash wood pellets that sell in bulk for about USD $105-130/tonne  for
the greenhouse heating industry in Southern Quebec and Ontario. 

Switchgrass pellet fuel at present should not be promoted as a solution to
the wood pellet fuel shortage for the residential heating industry. In
certain types of stoves they can burn be used, however the grass needs to be
overwintered, and it is used more conveniently as blends with wood fuels.

I think they could sell for about $3/bag if you wanted to blend them with
wood fuels. However our focus should be on bulk commercial pellet grass
fuels to start the market without problems and work on improving fuel
quality for the residential market.

At our present rate of switch grass processing in Chariton Valley we could
supply 4000 tons per month but it would take a few months to get into pellet
production. Right now we're putting it all into a boiler.

Roger, what's the wholesale price for switchgrass pellets? $2/bag?

What can SWG pellets sell for retail? $3-$4/bag?

Ok, and where can I get these switchgrass pellets wholesale now?

A question for Roger Samson I take it...
