A cost analysis is performed assuming a 30 year lifetime for PV and a 35 year lifetime for PTC.
A SB system with a 30 year lifetime is typically not designed to reach capacity until near the end of that 30 year period.
A detailed economic analysis reveals the technology can be installed for $0.58/watt and deliver a levelized cost of heat at 3.01 cents per kWh over a 20 year lifetime.
Analysis is performed for a fifty year lifetime of the overlay.
The results show that using Method A, over a 15-year lifetime, EROIstnd, EROIide, EROI3,1, and EROI3,1+e are expected to deliver EROIs of approximately 11 1, 20 1, 7 1, and 6 1, respectively.
The mission foresees a series of satellites, each having a 7.25-year lifetime over a 15-year period starting with the launch of Sentinel-2A foreseen in 2013.
Modern reactors typically use about 1,000 tonnes of fuel over a 60-year lifetime, so an operator would have to be subsidised to the tune of about £250m to make buying Mox fuel economic.
Comparisons with a 25-year lifetime deorbiting suggest a significant performance improvement.
HFC-134a, that accounts for the bulk of HFCs used, has a GWP of 1,430 over a 100-year lifetime.
"We can now be confident of a 4-year lifetime and talk seriously about a 6-year lifetime," Werner says.
