Battery based electric vehicles of today and tomorrow.

The fact there are unused electrons on a wire waiting to be used is the definition of storage.

Look at all those lines with holding capacity...

Amazing that a wire functions as a battery.
Why don't we just have lots of wire in our cars and store electricity in them that way? Who needs complex chemistry!

Wires pre date battery tech...

Wires pre date battery tech...

How do the wires store gigawatt-hours of electricity?
And with such an amazing storage capacity, why are people investing in battery storage?

The grid has no "Storage Capacity." You use it, or you lose it. It runs any way.

you guys need a physics lesson...but this might suffice for a quick lesson...

The second paragraph...

"At present, the U.S. has about 24.6GW (approx. 2.3% of total electric production capacity) of grid storage"

Amazing what a person can learn if they don't get all intellectually stubborn.

Oil May Hit $380 Per Barrel

I guess a barrel of this high powered crude would make a Whopper of a battery?

The grid is our storage capacity in this nation.

That's your original quote.

The grid is not our storage capacity.

The grid has storage capacity available to it and is the energy distribution network; the storage is connected to the grid.

Similarly, the grid itself isn't the nation's generating capacity; most generators (I'm sure your know that not all of them are) are hooked up to the grid.

At present, it probably has the majority of the nation's storage capacity connected to it (in the form of pumped water, presumably measured in GWh, not GW).

I can't put power into the grid for storage; that storage isn't storage for the nation in general but only for the generator that has direct access to it; they can put power from it - typically by running stored water through the dam turbines - and then put it on the grid.

When large battery storage is available (like in Oz), they'll be able to consume excess power from the grid and store it, but it's still not available for the nation in general but is just another power consumer and producer, connected to "the grid".

I feel this an about-face post...you had to admit the grid has storage capacity while at the same time not admitting it.
