Thanks for that link, dspp.
I have been taking an interest in companies like: GSF (Gore Street Energy Storage) and GRID (Gresham House Energy Storage), who invest in battery storage systems, but I would think that any real (investment) potential ought to be from companies involved in the actual development and discovery of battery and other storage related systems, and in that respect I wouldn't have much idea as to where to direct investments.
(I have a small holding in GSF).

Is this mainly about locking in a cobalt supply, before someone else nabs it.
I wonder to what extent Tesla will support past generations of its batteries. Anecdotally, its early cars are not well supported in terms of parts and there is a year's waiting list for replacement batteries.
Perhaps in storage applications this would not matter, a battery is a battery is a battery.

2020 will see a rise of almost six times the storage capacity in ISO markets
FOLSOM, Calif. – The California Independent System Operator (ISO) connected the
largest battery storage resource in the nation to its power grid last month, signaling an
era of rapid battery growth for the ISO in the next several years.
The initial phase of LS Power Group’s Gateway Energy Storage Project in San Diego
County came online June 9, adding 62.5 megawatts (MW) of storage interconnection to
the ISO grid. The power grid, which serves about 80 percent of California and a small
portion of Nevada, currently has just over 216 MW of storage capacity in commercial
operation. If all planned projects in the interconnection queue are completed on
schedule, storage capacity will jump to 923 MW by the end of 2020, a six-fold rise from
136 MW at the beginning of the year. "

One of the 5 is RES, but I am not sure who the others are
RES is building one of the five lithium-ion projects SDG&E announced on Monday, a 30-megawatt facility expected to be completed by the end of next year at the SDG&E Miramar substation.
There is a lot more coming

And I'm going to make the same comment on this report. The MW output does not measure the capacity of the energy stored in the battery.
I have no idea from this report as to what the energy storage is. A few car batteries and some fancy electronics could deliver the quoted power for a few milliseconds. OK - its unlikely to be as bad as that. But why is the appropriate figure of MWh not quoted? Is it because it is trivially small when compared to the need to iron-out long term fluctuations in massive wind-power installations? Does it compare with pumped-storage?
dspp wrote:Scanning those these large scale storage systems appear to be being sized at about 4:1 MW:MWh, i.e. at max capacity they would give 4-hours. I'm sure they have been doing quite a lot of modelling and it is striking that they are all in the 4-5:1 range, so that would appear to be a sweet spot. There are enough of them that it may well become a rule of thumb to use when journalists only quote one number.

And regular inspections to check the insulation is intact and no one is going to get incinerated putting a screw into the wrong place!
The tech is interesting, and might even find a home, but the idea that it can be used as a straight brick substitute in houses is laughable.
