Since the lead-acid battery was invented in 1859 in time to power Civil War telegraph communication between armies in the field and military and civilian leaders in Washington, D.C. we’ve witnessedEnergy integrationof about five times.

Battery buzz has been building because of portable power.

So what about batteries? Well, No. 2 on the World Economic Forum’s annual list of breakthrough technologies is next-generation batteries that will allow for grid-scale energy storage.

According to an Altair press release, “Going beyond lithium-ion, Altair’s lithium-titanate-based battery systems are among the highest-performing and most-scalable, with applications that include battery cells for military artillery, battery packs for hybrid vehicles and energy storage systems for large-scale stationary power services.”

The most exciting development for storage technology may be the product of one small Scottsdale, Arizona, startup Fluidic Energy.

Fluidic’s proprietary zinc-air battery technology and integrated intelligence may be the battery technology innovation that checks the boxes: higher energy density, lower cost, better safety, and longer life.

Zinc-Air Batteries, like a marathon runner, exert a steady flow of energy over a longer period of time.
