Converting Coal Plants to Biomass

Converting coal plants to burn wood chips and other biomass is a cost competitive way to reduce reliance on coal, a new study suggests. Coal-powered generating stations retrofitted to run on a mixture of coal and dried wood pellets can produce cost-competitive, emission-reduced electricity even without the advent of a cap-and-trade system, according to a new biomass life cycle analysis published in the Journal of Environmental Science and Technology.

For utilities under pressure to meet renewable portfolio standards, biomass should be considered along with wind, solar and small-scale hydro, says Heather MacLean, the lead researcher and an associate professor of civil engineering at the University of Toronto.

“The study results suggest that biomass utilization in coal generating stations should be considered for its potential to cost-effectively mitigate” greenhouse gases from coal-based electricity, the paper concluded.
