  1. CO2 Pipeline Transportation Technology Transfer Package(Version 1.0) August 17, 2006 Carbon Capture and Sequestration Technologies Program Massachusetts Institute of Technology

  2. Overview • Package Contents • National CO2 transportation obstacle layers • Module to calculate pipeline diameter (D) • Module to identify the least-cost path connecting a CO2 source to a given sink (L) • Economic module to calculate the total and annualized CO2 pipeline transportation cost

  3. Package Delivery • Data: • Data CD contains national obstacle layers. • Tool • Tool is delivered in a mxd file for ArcGIS 9.1. • Documentation

  4. MIT CO2 Transportation Cost Calculation Tool Structure

  5. Pipeline Diameter Calculation –Methodology • Doubling the CO2 mass flow rate will increase the pipeline diameter by 32 %.

  6. Pipeline Diameter Calculation – Implementation • Given a CO2 flow rate from the user and assuming a pressure drop of 49 Pa/m, we generated a look-up table for pipeline diameter.

  7. Pipeline Diameter Calculation

  8. Least-cost Pipeline Path Selection and Length Calculation – Methodology • Pipeline construction costs vary considerably according to local terrains, crossings (waterways, railways and highways), protected areas, and populated places. Obstacle grid layers (spatial unit: 1x1 kilometer) are used to determine the least-cost pipeline route. • Current version will identify the least-cost path and calculate its length for matching one source to one sink.

  9. Obstacle Conditions and Their Relative Cost Factors * Values and/or methodology may be updated after working with Kinder Morgan later this summer; * Values are based on 8-inch diameter pipelines;

  10. (continued) • Apply Cost Factors to calculate Land Construction Cost per grid cell (1x1 kilometer) LLC = Aggregated Cost Factors * Base Cost here: • Aggregated Cost Factors= (1+∑(cost factor*8/D)) • Base Cost = D/8*(base cost of 8 inch pipeline)

  11. Least-cost Path Selection and Length Calculation – Implementation Procedures to identify the least-cost path • Pipeline diameter is calculated; • Obstacle layers’ relative cost factors are adjusted according to pipeline diameters; • All obstacle layers are aggregated to get a total cost raster layer; • Direction (back link) raster layer is calculated; • Least-cost path is identified by using CostPath function in ArcObject; • Least-cost path length is fed back to the total cost model to get the total cost.

  12. Pipeline Total Cost • General Equation • Annualized Cost = Land Construction Cost * Capital Charge Factor + O&M Cost • Capital Charge Factor • Use 0.15 by default • O&M Cost • The O&M cost is estimated to be $5,000*Length (in mile) per year, independent of pipeline diameter

  13. Land Construction Cost (LCC) Calculation • MIT Correlation • LCC = a * D * L • a = $33,853; • D: pipeline diameter in inches (function of CO2 flow rate); • L: least-cost pipeline path length in miles; • Users are allowed to replace the default a value in the MIT correlation.

  14. Land Construction Cost (LCC) Calculation (Continued) • CMU Correlation • LCC = a* Dx * Ly * z • z: region weights; • a= $42,404; • x=1.035, y=0.853; • z values

  15. Region Map

  16. MIT-CMU LCC Comparison • MIT Correlation: $33,853/in/mile • CMU Correlation: ($/in/mile)

  17. Tool Interface

  18. Future Work • Implement many-source-to-many-sink matching (system optimization) • Update the obstacle layers and the associated relative weights • Allow users revise the pipeline diameter calculation by changing the pressure drop default
