Question

question 3. use data from the table above to calculate the cost of using each solution to store the 16,000 mwh of energy that would have been needed to prevent blackouts in lubbock during the texas storm. show your calculations using meaningful units. question 4. choose the solution that you would recommend based on total cost. how much land area would this solution use? clearly indicate which solution you have chosen, and show your calculations using meaningful units.

Explanation:

Step1: Calculate for Moss Landing Li - Ion Storage System

The energy storage capacity is \(1600\) MWh. To store \(16000\) MWh, the number of systems \(n_1=\frac{16000}{1600} = 10\). The total cost \(C_1=10\times400\) million \( = 4000\) million \(=\$4000000000\).

Step2: Calculate for Single Battery Li - Ion Storage System

The energy storage capacity is \(4\) MWh. The number of systems \(n_2=\frac{16000}{4}=4000\). The total cost \(C_2 = 4000\times2\) million \(=8000\) million \(=\$8000000000\).

Step3: Calculate for Pumped Hydro - Gravity Storage System

The energy storage capacity is \(8000\) MWh. The number of systems \(n_3=\frac{16000}{8000}=2\). The total cost \(C_3=2\times480\) million \( = 960\) million \(=\$960000000\).

Step4: Calculate for Flywheel Kinetic Storage System

The energy storage capacity is \(0.25\) MWh. The number of systems \(n_4=\frac{16000}{0.25}=64000\). The total cost \(C_4=64000\times50000=\$3200000000\).

Based on total cost, the Pumped Hydro - Gravity Storage System has the lowest cost among the four.
The land area used for one Pumped Hydro - Gravity Storage System is \(400\) acres. For \(n = 2\) systems (to store \(16000\) MWh as calculated above), the land area \(A=2\times400=800\) acres.

Answer:

• Moss Landing Li - Ion Storage System: \(\$4000000000\)
• Single Battery Li - Ion Storage System: \(\$8000000000\)
• Pumped Hydro - Gravity Storage System: \(\$960000000\)
• Flywheel Kinetic Storage System: \(\$3200000000\)
