Tom M.,
The mention of 5000 hours/yr is an average of 14 hrs per day. But how
much power do they need? Minimum expectations, average, and maximum
and peak requirements are all very different. If the 4 houses want 20
kW each, that is different from power for basic LED lighting and fans in
gas heating and a refrigerator running. 5 kW max and 3 to 4 kW
sustained for 14 hours is withing reach.
What did your requester specify? Any mention of the available
biomass? In what climatic region? Summer houses in Wisconsin that
are only occupied for 4 to 8 months are different from Alaska 12 month
residences.
ANY size of operational system will find some people who will want it.
Then the question becomes the price they are willing to pay.

Tom,
My request is technology agnostic at this point. Any style of
pyrolysis or gasification are welcome. I’m looking for small,
reliable, and maintainable. What manufactured gasifier system can
deliver power to four houses in a microgrid for 5,000 hours per year?
The fuel form and moisture is an essential part of the geometry of the
reactor. We can make the fuel to suit. Over the years we have seen
several small scale systems which have not gone beyond one or two
units. Are there other suppliers, like the ones mentioned, where you
can find systems which have operated for 5,000 hours or year or more?
Are there gasifiers that have been integrated into microgrid systems
with diesel, wind, or solar?
Thanks
Tom

Tom Miles,
You might want to paint somewhat a more complete picture, the
"successful" units may need to be fed less than 10% moisture wood,
less than 3% fines, which is a rarefied wood source indeed. Most are
also reliant on "filters" that have to be shut down and replaced
periodically and a host of other aspects that reduce the potential in
the market.
A 20 kw unit by US Standards, is good for one house.
If those who wonder what has gone on with the gasification list,
perhaps because of the lack of innovation to reduce the narrowness of
the feedstock, notably this list is primarily focused on downdraft
systems, there are approaches that expand the application base and
increase market necessary to prevent saturation at a low level.
Energy prices or availability has repeatedly cycled gasification
applications up and down, from coal fired "town gas" units replaced
with natural gas, to WW II fossil fuel shortages. However, there are
applications not subject to this cyclic effect.

I received in inquiry last week from someone looking for a microgrid
scale gasifier to power four homes in a remote off-grid wooded area.
What suppliers do we have for that scale?
We have seen some reliable systems at a larger scale. All Power Labs
(_http://www.allpowerlabs.com/),_ <http://www.allpowerlabs.com/%29,>
Volter (volter.fi), Entrada (_http://www.entrade.de/_) and Spanner
(_http://www.holz-kraft.de/en/company/102-spanner-re-2-company_) all
seem to be selling refined units at the 20kWe+. Are there others?

Hello Doug.
Re:
“It's a mute point drawing the low price of gasoline into our discussions”
A moot point?
I was only responding to your questioning the lack of traffic to this
forum, not its mission.
Most people spend their discretionary time doing what seems most
important to them, I think. When gasoline is USD$4.00 per gallon, the
idea of developing or supporting cheaper alternatives rises higher
towards the top of the to-do list.
Oh- maybe you did mean “mute” point. In either case, I won’t bring it
up again.

Hi Pete,
We are only as professional as our need to breath the same air.
Because we all are at different levels of knowledge, none of us can
know how to answer, or ask questions, due to the differing perspective
of how our interests have "drawn us in". We all share that
gasification has such promise for energy applications, so asking
questions or providing answers is the reason this list was created.
Yes, there have been other groups form to discuss gasification, There
are no short cuts to reliable gasifier performance, but information
without scrutiny can only speak for itself. This Forum and it's
extensive collection of related information, was the first to
recognize the need for such discussions and become available to us
all. There never has been any restriction on who participates, and
some very good people have shared with us particularly in the earlier
years.
It's a mute point drawing the low price of gasoline into our
discussions relating to an alternative for fossil fuels! It's not
about the price, but availability which can change over night, and for
me, that means being able to be self supporting in time of need. NZ
has had a reported 32,000 quakes this last year, plus major storms
that destroyed electrical distribution facilities. Are any of us
really prepared for the inconvenience when, not if, it comes?

Hello Doug.
I view this list to be for the professional for the most part, so
I hesitate to join in unless I have a question that I can clearly
describe.
But I think at least part of the reason for the lack of traffic is
that there are now several other websites that cater to hobbyist
and advanced tinkerer wood-to-electricity crowd:
-Yahoo woodgas group,
-Yahoo charcoal gasifier group
-Wayne Keith’s driveonwood.com website
-allpowerlabs.com
And I am sure there are many others.
In addition (although I have been flamed for even mentioning it),
gasoline for USD$2.00 per gallon does take the edge off for many
people.
