Overview of the Algae System Spreadsheet
The economic impact of CO2 photosynthesis on electric costs is reflected in the ultimate cost per kWh of electricity generated by fossil fuel plants. Here that cost is designated by the variable FutureGen Prime Elex Cost With CO2 and NH3 Sales ($/kWh) = 0.093114465230852. A negative number means the value of the CO2 is high enough that the fossil fuel plant can give away electricity and still make money.
In the table of variable names and values that follow, the primary control parameters are as follows:
- (ShortTerm=0 or LongTerm=1)
- (MVsSystem=1 or JBsSystem=0 or SolixSystem=0)
- (NaturalGasSystem=0 or CoalSystem=1)
- Default Amortization Interval Bond Rate (%/year)=.05
MVsSystem (1) stands for Miguel Verhein's system, which is the Algasol LLC photobioreactor model "Alga6". It has a much lower cost photobioreactor vessel and support platform than the system described in the link to "the algae system" below which was developed by James Bowery as an alternative since other algae cultivation system costs were poorly documented or were verifiably uneconomic even at the macroengineering economies of scale. If "(1)" appears next to "MVsSystem" then the numbers below refer to MVsSystem's characteristics. EquatorialOcean (0) is a speculative system that is being modeled with its value is '1' that takes advantage of the high insolation of the equator and thermal buffering of the ocean.
The primary inputs to the algae system are H2O, CO2 and NH3, delivered by pipeline. A complete breakdown of inputs is given in the Chemistry section of the spreadsheet.
The cost basis for the algae system is given in the AreaCost section of the spreadsheet, as costs are levelized and normalized to cost flow per insolated area of photobioreactor surface.
The market basis for the algae system is given in the Net section of the spreadsheet and the protein price per unit mass. See The Foresight project Global Food and Farming Futures final report for the long-term price outlook for protein.
Total system quantities (such as total land area required, total profit, etc.) are given in the Global section of the spreadsheet.
Employment figures are given in the Employment section of the spreadsheet.
Price supports to secure investment in the system are given in the PriceSupports section of the spreadsheet.
Environmental impact of the reengineered coal baseload power generation is given in the FutureGen section of the spreadsheet. These estimates are normalized per baseload power.
As thermal issues are a frequent failure mode of algae projects there is a dedicated Thermal section of the spreadsheet.
