Thank you Gordon
Please excuse me if I do not follow the correct format here. I have had trouble aligning the "=" but I think it will make sense.
I am seeking feed back on the following information I have prepared for a Presentation I will be delivering. Thank you all in advance for your time. Have a great day brendan
100% National Storage Model
Referring to a paper by the Federal Bureau of Resources and Energy Economics titled, “Energy in Australia 2014”, on P24 it is stated “Australia consumed 5884 Petajoules of energy in 2012-13, with 94 percent coming from fossil fuel sources …”
I have used this figure to perform the following calculations quantifying a cost estimate, should batteries be adopted as the sole means of energy storage in Australia.
5885 Petajoules converts to 1634 Tera Watt hours.
94% x 1634 TWh = 1536 TWh
Assuming that the fossils fuels were consumed with 30% efficiency, we get the productive conversion of,
1537 TWh x 30% = 461 TWh of productive energy consumed per year
Working out the Daily Energy Consumption we find,
DEC = 461 TWh / 365 days
Daily Energy Consumption = 1.26 TWh
Assuming, 100% battery efficiency and a national storage requirement of 5 days of energy consumption, not including onboard vehicle storage, we get,
National 5 Day Energy Storage = 1.26 TWh x 5 days
National 5 Day Energy Storage = 6.31 TWh
Assuming the use of 129 MWh Big Batteries as a source of storage and noting 1 TWh = 10^6 MWh we can work out the number of batteries required,
Number of batteries required = 6.32 x 10^6 MWh / 129 MWh
Number of batteries required = 48,945.0 Big Batteries
Assuming the cost of these batteries is $200 Million per each, we can calculate the total cost,
Total Purchase Price = 48,945 Big Batteries x $200 Million/each
Total Purchase Price = $9.8 Trillion
Paid off over 15 years the annual cost becomes,
Purchase Price per year = $9.8 Trillion / 15 years
Purchase Price per year = $652.6 Billion
Assuming a national population of 25 Million, we can work out the cost per person,
= $ 652.6 Billion / 25 Million people
5 Day Standby Energy Cost Per Person = $ 26,104 per person per year for 15 years
