California officials expect zinc energy-storage technologies to help the state attain 100-percent clean energy by 2045, proving cheaper and safer than lithium-ion while holding a charge longer.
“Some of them are looking for 25 to 50 hours of storage,” said Mike Gravely, research program manager at the California Energy Commission.
“Some of them are looking to provide residential homes the storage they need to ride through these PSPS (public-safety power shut-off) events that California has, or to provide the reliability and resiliency that a home should have, and they’re in the size that they would fit in your garage, or they would fit something about the size of your outside air conditioner.”
California recently invested $16.8 million in energy-storage technologies beyond lithium-ion, many of which employ zinc.
“If you look past lithium ion, probably zinc
