Abstract
Willow biomass crops have been shown to be a good fuel for farm-based power
production using advanced gasification technology. The fuel gas can be used for
generating electricity, using microturbines modified to operate on low-BTU gas,
or for other farm energy needs. Willow biomass was found to make an excellent
fuel for ash-rejection gasifiers with a predicted net gasification efficiency of
about 85 percent. The main drivers to the cost-of-electricity were found to be
associated with the harvesting, handling, and transporting of the willow biomass,
accounting for 40 to 50 percent of the annual operating cost. In the present
study, analysis showed that developing a method to co-gasify willow with
various amounts of low-cost wastes, such as dairy farm animal waste, can be an
excellent way to reduce the fuel cost, to increase the overall fuel availability and
help work around problems resulting from seasonal availability of bioenergy
crops. Co-gasification of dairy farm wastes along with willow offers an
economical way to dispose of the wastes and manage nutrient flows on a dairy
farm. The power generated from the animal waste can be used on the farm or
sold to offset the cost of waste treatment.
