The most striking thing in this area, and many
others in British Columbia, is the abundance of dead and downed wood fiber;
both, in the logged areas with their residual fiber and in the standing
forests. The Pine Beetle has left vast tracts of forest dead in its wake;
generating a situation that offers salvage of the affected trees possible.
Presently the timber affected by Pine Beetle offers viability as a saw log, but
the window for use as sawlogs is coming to a close. One is then faced with the
question of what to do with this fiber and other waste fiber at large in the
forest.
I have had limited exposure to individuals that
have installed Co-generation plants that burn wood waste from milling processes,
to both generate electricity and to use heat for kilns and the like. This has
led me to begin contemplating the possibility of a standalone wood electrical
generation station.
Preliminary investigation,
very preliminary, indicates a favorable opportunity. I have reviewed some
modeling done by BC Hydro around a centralized plant that relies on a large
catchment area to supply fiber (2010 Resource Options Report - Wood Based
Biomass Potential Report). The model was generated with an installed capacity
of 35 megawatts. The business model as depicted offers some challenges to
viability, one of the primary challenges is related to the transport of fiber
over long distances.
This spurred the
contemplation of a smaller mobile plant that could be readily relocated to
areas of high fiber concentration and where there is a confluence of other
required operational components, by way of example, BC hydro power lines of
sufficient capacity to meet the transmission demands of the plant and perhaps
water resources.
In adapting the BC Hydro
model to the mobile plant, and then performing sensitivity analysis with
respect to transportation savings, there seems that viability is in the offing.
This is very preliminary assessment and much due diligence is required.
However, further investigation is warranted.
I am posting this brief
discussion in the hope that perhaps someone may find the concept of interest
and wish to engage in exploring the idea further. Thank you for your
consideration.
