Not exact matches
What the authors would like to see is the prospect of limited and expensive coal get a serious consideration; currently, most energy policy decisions, such as a focus on carbon capture and storage for coal
plants,
assume that coal will remain cheap enough to compensate for its added
costs.
After all, these
costs assume all emissions have been zeroed, and it's hard to zero the 4 GtCO2e per annum from pure agriculture, even without incidental emissions of
planting, harvesting, processing, production, and transport.
Just recently, Duke was given authority by Bush's former OMB Director, Mitch Daniels to force their customers to
assume the risk for the
plant even though the utility commission did not require Duke to file anything near a current construction
cost estimate for the 630 Megawatt
plant they are seeking to build in what is already the largest concentration of coal fired capacity in the world, SW Indiana.
Assume typical nuclear
plant of 1 GWatt capacity, 1 Euro = 1.32 USD (today's exchange rate), gives $ 2.97 billion
cost.
If a reader has the $ / kW (stated), discount rate (
assume 8 %), capacity factor (missing) and projected years of operation (stated) one can use my worksheet «A Financial Worksheet for Computing the
Cost (US cents / kWh) of Solar Electricity Generated at Grid Connected Photovoltaic (PV) Generating
Plants» that was published in the Journal of Solar Energy Engineering, August, 2002, Vol.
«Studies so far
assume that what we do will
cost $ 600 per tonne — this is a study by the American Physical Society, and one study by MIT, Stanford and Berkeley even
assumed $ 1,000 per tonne — for
plants which are a) industrialised and b) have a much bigger scale, so not one thousand tonnes per year, but a factor one thousand more, so a million tonnes per year.
•
Cost of electricity (harsh environment, short
plant life, diesel backup generators, transmission line problems)--
assume $ 500 / MWh
• Annual
cost of «CO2 Deposition
plants» (including construction, operation and maintenance, accommodation facilities and fly - in - fly - out airports)--
assume $ 100 million per
plant per year.
• CO2 to be sequestered per year = 4 billion tonne • Number of Deposition
plants per year = 1,787 • Electricity required per year = 2.47 × 10 ^ 18 J = 686,000,000 MWh •
Assumed electricity
cost (including, diesel back up generation, transmission, harsh environment and short
plant life) = $ 500 / MWh •

assumes its depreciation is on a 100 % use basis.
«A comparison of the levelized
cost of energy (LCOE) revealed that the LCOE of $ 148 per MWh for the first CSP

assuming that the temporary 30 percent Investment Tax Credit is extended.
At a
cost of $ 34.26 per ton (per the EIA's 2006 figures), you're looking at $ 34.26 million a year, or about $ 685 million over the course of 20 years (the average life most power
plants, both renewable and non-renewable are given as a base measurement),
assuming no price increase over the next two decades... which is not a safe assumption to make.
Assuming that each power
plant we built
cost that amount, the total
cost would be 23.07 trillion USD.
