Tom & list,
That the ICM plant shut down was already physically on site and working
is of concern.
Certainly our view and experience is that functional gasification
systems should be capable of multiple outputs where required. The
successful trial at a sawmill Real Power Systems have just completed was
certainly based on this concept, with clean producer gas and high
quality char as the products from the gasifier, a secondary pyrolysis
retort using the producer gas also produced torrefied sawdust for a
briquetting trial for a specific end use, so perhaps in combination
could be described as a hybrid plant.
We have found multiple barriers to gasifier uptake, not many of which
are technical. The ICM experience perhaps more closely highlights that
projects must have sound economics to be sustainable, starting with
better outcomes than "business as usual" as a minimum. However local
politics and vested interests in maintaining existing business
arrangements (particularly in established waste management practice) can
present unexpected challenges.
Wishing everyone a safe and happy festive season.

Peter, It is a highly functional gasifier that makes two good products ?
gas and biochar - in variable proportions. As you know it is a challenge
just to sell a gasifier in energy markets that are dominated by low cost
natural gas. I had previously understood that the 200 tpd gasifier
referred to in the article was a pilot facility that was owned and
operated by ICM. However, it appears that it might have also been
operated on trial by the county as a means of wood waste reduction and
the term ran out. That?s pure speculation but it was not generating heat
or power for a customer. Tom

Just curious - is the ICM technology based on gasification or pyrolysis?
Maybe this just highlights the fact that you cannot expect any single
technology to deliver multiple outcomes. Peter Mason. A problem well
defined is a problem half solved and always start with the end in mind.
