model.ocean_solution
Implement all the calculations required for solutions in the Ocean sector.
Read the scenario inputs file. Load the pds scenario, ref scenario and set up the unit adoption.
Return the difference between the units adopted in the pds scenario and the reference scenario for the final year of the reporting period.
Return the functional units adopted in the pds scenario only, for the final year of the reporting period.
Return the world current adoption as a percentage of the total functional units adopted for the base year.
Return the functional units adopted for the start year as a percentage of the total area (or total addressable market if appropriate) for the start year of the reporting period.
Return the functional units adopted for the final year as a percentage of the total area (or total addressable market if appropriate) for the final year of the reporting period.
Calculates the annual cumulative first cost of the implementation of global units by multiplying global units (including any replacement units) installed by install cost per unit. Both PDS, Reference and conventional scenarios are calculated.
Return the Marginal First Cost for the emissions reduction calculated for the study period.
The Marginal First Cost is the increase in first costs for the emissions reduction calculated for the study period. This reduction may be partly due to implementation units installed after the base year but before the study period, and hence the first costs of these units should be counted. It is the Cumulative First Cost of the PDS minus the Cumulative First Cost of the Reference Scenario(REF) or the increase in installation costs of the PDS over the REF for the study period. (US$2014 bn).
Return the Cumulative First Cost for the solution.
The Cumulative First Cost is the total cost of installations that provide the emissions reduction calculated. As this includes implementation units installed prior to the start of the study period, we include the first costs of all units from the base year to the final year of analysis (inclusive) in US$2014 bn.
Return the time series of the contribution of each new set of SOLUTION implementation units installed over the lifetime of the units.
Calculated only for new or replacement units installed during the analysis period. Fixed and Variable costs that are constant or changing over time are included.
Return the operating cost (or operating savings) of all implementation units (end year minus start year of study period). (US$2014 bn)
Return the sum of all operating cost (or operating savings) of all implementation units across the study period. (US$2014 bn)
Return the discounted cashflows time series (PDS relative to the Reference Scenario - first cost and operating cost) for the full lifetime of a single implementation unit.
Return the sum of the net present value of all cashflows (PDS relative to the Reference Scenario - first cost and operating cost) for the full lifetime of a single implementation unit. ($US2014 bn)
Return the timeseries of all discounted cashflows (first cost and operating savings) for the full lifetime of all implementation units adopted during study period.
Return the sum of all discounted cashflows (first cost and operating savings) for the full lifetime of all implementation units adopted during study period. (US$2014 bn)
Return the length of time taken to recover all investments costs where cashflows are NOT discounted.
If a decision maker is considering an outright investment in the solution technology, he would want to know the payback of the solution in the absence of any conventional comparator. Some payback analysis calls for discounting cashflows, others do not.
Return the length of time taken to recover all investments costs where cashflows ARE discounted.
If a decision maker is considering an outright investment in the solution technology, he would want to know the payback of the solution in the absence of any conventional comparator. Some payback analysis calls for discounting cashflows, others do not.
Return the length of time taken to recover all investments costs (above and beyond the conventional technology costs) where cashflows are NOT discounted.
If a decision maker is comparing two projects, one with the conventional technology,and another with the solution technology, she would want to know the relative payback. Some Payback analysis calls for discounting cashflows, others do not.
Return the length of time taken to recover all investments costs (above and beyond the conventional technology costs) where cashflows ARE discounted.
If a decision maker is comparing two projects, one with the conventional technology,and another with the solution technology, she would want to know the relative payback. Some Payback analysis calls for discounting cashflows, others do not.
Return the discounted lifetime cost of the solution.
This is calculated as PDS - REF, including First Costs and Operating Savings, but only for those years of the analysis, divided by the total emissions reduction during those years.
Return the time series of Net Profit Margin of all implementation units across the study period.
Return the Net Profit Margin of all implementation units during the study period only (value at end minus value at start).
Return the Net Profit Margin for the full lifetime (to 2139) of all implementation units in use during study period.
Note that this may include units adopted prior to the start year, and may extend past the end year.
Return the time series of reduced emissions.
Annual CO2 reductions by region and year are calculated by adding reduced emissions derived from the electric grid, the replaced emissions derived from clean renewables, the net direct emissions derived from non-electric/non-fuel consumption, and the reduced emissions derived from fuel efficiency, and then subtracting the net indirect emissions. Most solutions will not use all of the defined factors.
The emissions values used are from the regional future grid BAU CO2 emission intensity values (by year) from the AMPERE 3 MESSAGE Base model used in the IPCC 5th Assessment Report WG3.
Return the sum of all emissions reduced in the PDS Scenario versus the REF Scenario over the study period. (Gt CO2)
Return the maximum reduction of all years in the reporting period
Return a time series of the sequestration amount for each year in the reporting period
The total CO2-eq sequestered in the PDS but not in the REF Scenario.
Return the highest rate of sequestration during the period of analysis.
Return CO2 Sequestered in the final year of the reporting period.
Return the time series of reduced PPM of CO2 equivalent for each year in the reporting period.
Each yearly reduction in CO2 (in million metric ton - MMT) is modeled as a discrete avoided pulse. A Simplified atmospheric lifetime function for CO2 is taken from Myhrvald and Caldeira (2012) based on the Bern Carbon Cycle model. Atmospheric tons of CO2 are converted to parts per million CO2 based on the molar mass of CO2 and the moles of atmosphere. CO2-eq emissions are treated as CO2 for simplicity and due to the lack of detailed information on emissions of other GHGs. If these other GHGs are a significant part of overall reductions, this model may not be appropriate.
Return the CO2 atmospheric concentration change (in parts-per-million) estimated as a result of the PDS scenario compared to the REF scenario, in the final year of the reporting period only.
Return the CO2 atmospheric concentration change (in Parts-per-Million) estimated as a result of the PDS scenario compared to the REF scenario, in the final year minus the penultimate year.
Return the expected reduction in land/ocean degradation (of solution land/ocean type) as a result of the adoption of the solution over study period.
"Calculate the sum of the increase in adoption in the final year and the degraded area under protection for the solution in the final year. Return this sum multiplied by the carbon storage in the protected area type.
