For a single Ca-looping cycle installed on a 500MW power plant:
# Amount of CaO from purge annually = 12.6 kg CaO/s × 365 days/year × 24 hr/day × 3600s / hour = 3.97 × 10 kg CaO/ year
# Cement that can be obtained from purge annually= 3.97 × 10 kg CaO/ year × 1 kg cement/ 0.65 kg CaO = 6.11 × 10 kg cement/year
# Net electricity generation in US:  (415 + 318 + 51) GW = 784 GW = 7.84 × 10 W
# Number of 500 MW power plants: 7.84 × 10 W / 5.00 × 10 W = 1568 power plants
# Amount of cement that can be produced from Ca-looping waste: 1568 × 6.11 × 10 kg cement/ year = 9.58 × 10 kg cement/year
# Production from Ca-looping waste as percent of total annual cement consumption = [(9.58 × 10 kg)/ (1.10470 × 10 kg)] × 100 = 870%
Therefore, amount of cement production from Ca-looping waste of all fossil fuel based electric power plants in US will be far greater than net consumption. To make Ca-looping more viable, waste must be minimized (i.e. sorbent degradation reduced) to ideally about 1/10th of current levels.
