Ok rocks, I cannot claim a scientist background so let this article speak for me. He makes my points for me. I hope you will agree that this is a sober analysis from a man that knows more about the issue than either you or me.

One Expert's View On The Near-Term Future Of Energy Storage

At the same time, energy storage involves complex technologies in a complicated market. We will see a proliferation of use-cases and applications, some of which are still a few years out. And while storage will add a tremendous amount of value and let us add large amounts of renewables, it is not perhaps the Holy Grail. Jaffe cautions that batteries alone are unlikely to let us dispense with fossil fuels entirely.


Batteries won’t replace everything on the grid. They are not going to displace fossil fuel, energy efficiency, or demand response. They will start with a few applications. They are still going to be a ratchet in the toolkit of grid energy, but not the tool box.

That said, storage is a pretty large and important ratchet (or – to mix metaphors – Swiss Army knife) in that toolbox and it will be used in a variety of interesting and useful applications. Still somewhat of a novelty today, storage will become a commonplace and central part of future power grids in the visible future.

Thank you for a very interesting article. Yes, the author makes many excellent points. And right now I am pushing an effort at the manufacturing facility where I work to do a cost analysis on what the bumps on the grid cost us in terms of downtime, loss of components, plc's and drivers, loss of product, and the cost of variable rates. When the costs of the storage gets low enough, that would be a good investment for the company. As the author points out, economics are the determining factor.

Eos Energy Storage | Technology and Products

Low Cost/kWh At $160/kWh for the DC system, Eos is cost competitive with existing peak generation technologies

Extremely Long Lived Aurora is projected to last 5,000 cycles for a 15-year calendar life

High Energy Density Aurora has an energy capacity of 4 MWh housed in four 40-foot. containers, ideal for space constrained applications

High Energy Efficiency With a round trip efficiency of 75% in full depth of discharge applications, Aurora is one of the most efficient long-duration energy storage solutions

100% Safe Constructed with environmentally benign, non-toxic materials, the Aurora system has no mode of catastrophic failure and is safe to locate in urban areas

Here is a presently available battery that fulfills many of the factors the author was speaking of. And, like pv solar, this is a technology with a steadily decreasing cost curve.
