The elephant in the room -- unfortunately, there cannot be enough batteries made to support this. That is why I invested in Tesla -- don't care about EVs, but the battery play is good! Backup power for personal/family use? I use a Firman generator - 20 litres of fuel per day of operation at load. (here, $30 Canadian). Since the generator was only $300 and load is 3000W, this is a much better deal for me.
And... at the rates being bandied about here... if anyone EVERY offers, say, $1/KWh - That grosses me $70 per $30 of gas. I would take that incentive. Note that the generator would pay for itself every 10 days by my reckoning.. And the recycling of the motor is already a solved problem.
So... $1/KWh is way too much. $0.50/KWh is also too much (and note that my gasoline pricing is around $1.50/litre at the pump -- $22.41 US for 20 liters ...
So the actual amount should be around 32 cents per KW/h... 50 cents work fine because that factors in "wear and tear" -- do those numbers work for batteries? Of course, buying electricity is 7 to 15 cents/KWh here.
I would want LiFePo4 for this application; at current rates, a 10KWh battery runs $10,000. From that, I determine that I can "just" buy much more effective gas/natural gas/propane burning generators. Something like the Generac 6551. Natural gas is .23/c3 or around $1 for one hour of 7000W operation... actually looking competitive with electricity grid rates (except wear&tear on the generator).
Note that I do have a hybrid car. So, not "anti-electric" by any means. I just don't think that enough batteries can be made for this application. Certainly NOT be 2030 (6 years? Oh really?)
- tuatoru 4y ago> unfortunately, there cannot be enough batteries made to support this. Why do you say this? It contradicts what everyone in the industry thinks. There are no material shortages for the materials used in lithium batteries, and there are several alternative chemistries under active development, that are at least two of cheaper, more durable, or higher power-to-weight than lithium.

Where in the heck did you get that number? 10kWh of LiFePO4 batteries is more like $3k at current prices: https://signaturesolar.com/eg4-lifepower4-lithium-battery-48v-100ah/?setCurrencyId=1&srsltid=AeTuncpTxPvKfrxGAtr46WGFibDBPB5vvrhgblCB3e6AZfqXy90r4Wc534Y https://signaturesolar.com/eg4-lifepower4-lithium-battery-48...
- ratboy666 4y agoThank you! At those prices, it begins to make sense. Man, the prices have fallen!
