Lithium-ion (Li-ion) batteries accounted for 90% of all proposed grid storage projects in 2014, according to a new study by Lux Research.
A team at Harvard is pursuing a metal-free battery chemistry based on organic molecules called Quinones. The technology potentially offers an abundant and safe material to use for scaling up flow batteries, but according to the energy storage team at Lux Research in Boston, there are significant limitations based on project cost.
A remote town in Canada which lies 55km away from the nearest electrical substation, was supplied with a battery system aimed at shoring up the reliability of its electricity supply.
