5 GWh in what time? Gigafactory 1 was at 30 GWh per year in 2019 and they planned to ramp up to 54 GWh, according to Wikipedia. So probably per year? Which would make their production capacity 570 kW. Also according to Wikipedia, a production of 35 GWh per year which is 4 MW was estimated to require 300 MW of energy input.
- Tade0 4y ago> Which would make their production capacity 570 kW. I understand where you got this number, but I would rather stick to units which are easy to interpret. Yes, 5GWh per year or 570kW - in a sense.
- seszett 4y agoWhat is the point of comparing 300 MW energy use for production with 35 GWh/year (which is technically 4MW indeed) new battery capacity though? These are technically the same units, but they don't measure the same things.
- danbruc 4y agoI find that comparison quite interesting with respect to the energy intensity of producing lithium ion batteries. A factory that can produce two oil barrels per hour or seven 60 liter gasoline tanks per hour or will also produce 35 GWh storage capacity per year and would probably not consume anywhere close to 300 MW in the process.
- IshKebab 4y agoThey measure comparable things. The ratio is how many times you would have to discharge the battery to output enough energy to manufacture the battery. It's the capacity independent measure of embodied energy. An important metric.
