Observing the world of renewable energy and sustainable living

Storage Breakthrough – $100/kWh has been achieved

Cheap storage to counter the intermittent supply of renewable electricity is the missing link en route towards the desired renewable energy base of the future, but that problem could now have been solved. Technology has developed so rapidly in recent years that cost of electricity storage has been brought down from $1000 to $100 per kWh.

City College NY has improved an old concept of mangandioxide-zinc batteries. Result: 6000 charge-cycles for less than $100/kwh.
Price storage of a single kWh: 1.67 dollar cent or say 8 cent per day per 5 kWh/day household. Peanuts.
Can also be used for cars: 40 kWh battery for $4000. Bye-bye gasoline.

Mangan-Oxid is abundant and non-toxic.
This NYC startup is going to produce the batteries first:
