Who knows maybe even Tesla will license Electrovaya Technology, hopefully Elon Musk, who seems very pragmatic, stays away from the NIH “Not Invented Here” philosophy of many early market companies and sets giant battery engineering egos aside to guide Tesla Batteries to the logical conclusion, that is: big drying ovens to gas-off the roll-to-roll “R2R” process of sandwiching wet cathode and anode pastes to a separator is a waste of space, time, equipment and power consumption expensive, not to mention the resulting flat prismatic battery cell material produced has 50% less power density. Electrovaya has got it right and Tesla would be well advised to take a closer look at their sourcing, and maybe double the capacity of their Giant 1 GWAmp hour/year Gigafactory into a 2GWAmp hour/year factory using Electrovaya Technology and avoid buying all that old expensive R2R technology.

Thus, don’t look for “CAES” solutions to be used in smaller scale electrical generation and storage facilities for some time, until automated production and injection moulding takes over the production of the spray water/foam adapted ICE “Internal Combustion Engines” used in the Lightsail and SustainX solutions. The fact is these three solutions need alot of real estate and their “ROP” Rest of plan costs only make sense in 8MWAmp Hour sizes and larger.
