Did you ever look at the cost of distribution of electricity vs the cost of generation of the electricity?
There is a business opportunity when the EESU is cheap enough that a home goes off the grid. Home delivery of electricity via truck.
When will the cost of grid delivery exceed the cost of truck delivery?
For delivery by surface transport, you'd have to have truly massive ED (50x? 1000x?). Enabling incredibly cheap EESUs ($2 / kWh? 10¢ / kWh?). But, if you could do that, you could have power generators at their source, say coal or biomass or hydro or ..., "densifying" that chemical or other energy source into EESUs of much much higher ED. Then, transport of EESUs could match or beat long distance transport of, say, coal to power plants, and then power via the distribution grid.
Sounds like sci-fi, to me.
Would you build a rail line from, say, the massive but remote Hydro Quebec James Bay dams to connect to existing rail service to deliver power to Ottawa, Montreal, Toronto, New York city, Boston, rather than incur the costs and losses of conventional transmission grid?
EESUs would have to be fantastically economical, per kWh.
And, Hydro Quebec's capacity, as an example, is 36.8 GigaWatts. Which makes for 883 GWh, per day. At 1x's ~500 Wh / kg, those gajillion EESUs would weigh 883,200 tons - transport ~1 million tons, per day? At 1000x, 1,000 tons per day would be pretty doable.
But none of it really matters, if the price is $100 / kWh (10¢ / Wh), 883 GWh worth of EESUs would cost $88.3 Billion.
