Vanadium Redox Energy Storage
Via Utilipoint IssueAlert, a quick mention of this vanadium redox energy storage system that claims to have some remarkable properties, including a claimed 70-78% round-trip efficiency, up to 220 W/kg energy density, and a real-time energy storage ability (i.e., it charges as fast as it discharges). It does require a pump (they estimate it will need replacement every 5-7 years, ouch). All this without using heavy metals. Sweet!

"All this without using heavy metals"? What is vanadium????
Vanadium is a heavy metal but I think this shows real promise.
Interestingly enough, many of the non-conventional sources of oil contain vanadium which must be refined away. The Orinoco tars are riddled with the stuff.
Bears watching for sure
Okay, so maybe I should have said, sans lead.
