A state economic development grant is helping to fund an effort to find a cheaper and more effective ice repellent.
Its a problem that makes rooftop ice dams seem minuscule by comparison: how to prevent ice buildup on massive wind turbine blades.
Researchers at Iowa State University are trying to develop a cost-effective antidote with the help of a $303,000 state economic development grant.
The stakes are real for the wind energy industry in Iowa and other cold weather states. Energy production can fall by as much as 50% when blades are icy, and operators sometimes turn turbines off during icy weather to prevent damage to the machines, according to Hui Hu, a professor of aerospace engineering at Iowa State who is leading the research effort there.
Given our substantial wind resources
this has the potential to increase production, but to do it in an efficient and sustainable way, said Brian Selinger, who directs the energy office for the Iowa Economic Development Authority.
