Missouri S&T has installed two new advanced lead-battery microgrid systems at the campus’s EcoVillage, a “living laboratory” that is home to solar-powered houses designed and built by Missouri S&T students.
Members of Missouri S&T’s Microgrid Industrial Consortium want to use the microgrids to test advancements in lead battery energy storage for their potential use as a renewable energy source in communities of the future.
Two homes occupied by students will be individually supplied with stored electricity from the systems, which run off charging algorithms from a 24-hour, cloud-based control system.
To celebrate the installation, Missouri S&T will hold a ribbon-cutting ceremony for the microgrids on Friday, November 9 at 10am. The public is invited.
The Missouri S&T Microgrid Industrial Consortium is a collaborative research alliance that includes the Advanced Lead Acid Battery Consortium (ALABC), a research group and program of the International Lead Association (ILA); The Doe Run Co., a Missouri lead mining and battery recycling company; Ameren, Missouri’s largest energy utility provider; the Missouri Public Utility Alliance (MPUA); the Missouri Department of Economic Development Division of Energy (MO DED); and Missouri S&T’s Center for Research in Energy and Environment (CREE).
ALABC members NorthStar Battery and EnerSys, both global battery manufacturers, and The Doe Run Co. donated the equipment and funding to construct the new microgrids.
Leading with lead
Lead batteries are typically known as a tried-and-true rechargeable energy source. According to the ILA, up to 90% of modern lead usage is in the production of batteries. The ILA further states that more lead is produced by recycling than is mined, making it ideal for a circular economy. According to the 2017 National Recycling Rate Study commissioned by Battery Council International (BCI), lead batteries are the most recycled consumer product in the U.S. with a 99.3% recycling rate.
“With lead as a Missouri natural resource, this project provides opportunities to better serve our state’s economy and environment through energy research,” says Dr. Christopher G. Maples, interim chancellor. “This project perfectly aligns with S&T’s mission to integrate education, research and application to serve the state and solve the world’s great challenges.”
Missouri-based microgrid consortium partner Doe Run manages nearly the full lifecycle of lead. “From mining underground deposits, to supplying Missouri battery manufacturers with lead and lead alloys, to reclaiming and recycling lead from spent batteries, Doe Run provides more than a $1 billion a year in economic value to Missouri,” says Chris Neaville, the company’s asset development director and a 1987 geological engineering graduate of Missouri S&T.
