Minnesota Pledges 100 Percent Carbon-Free Energy. Is It Possible?
As Minnesota looks to scale up its use of renewable energy sources, a U of M energy transition expert weighs in on one potential source.
A few options: Nuclear fusion. Carbon capture. Flow batteries.
"Flow batteries are really cool," said Ellen Anderson, director of the Energy Transition Lab at the University of Minnesota. "That's an up-and-coming technology that could use things like iron that could come from Minnesota. They can last longer, they can be scaled up and used to save excess wind energy and solar energy and then inject them back into the grid 12 hours later or two days later even."
And even though there is a lot of excitement around adding renewable energy and storage to the electricity mix, Anderson said, there are also a lot of questions about how soon the state can phase out fossil fuels from the electricity sector.
