Capturing and Utilizing CO2 from Ethanol: Adding Economic Value and Jobs to Rural Economies and Communities While Reducing Emissions The NETL model calculates costs by pipeline segment based on inputs such as pipeline length, annual CO2 volume, input/outlet pressure, capacity factor, and number of booster pumps. Model output includes capital costs for materials, labor, right-of- way negotiations, CO2 surge tanks, pipeline control systems, and pumps. Operational costs include pipeline O&M, equipment and pumps, and electricity costs for pumps, by segment. The GPI/IHR study team mapped several pipeline network scenarios in ESRI’s ArcGIS to determine the route, length, and volume of each segment of the network.26 Ethanol plants ranged in size from 40 to 350 MGY, with many plants operating at around 100-110 MGY. Network design considered the location of large plants (at least 100 MGY and greater) for primary hubs or trunk line route, with smaller plants clustered along feeder lines into the trunk line. Segment properties were entered into the modified NETL model to calculate costs for each segment. Additional pipeline assumptions included a +10 percent scaling factor to account for route right-of- way issues, a pressure drop from 2000 psi to 1400 psi (field delivery at 1400 psi), and booster stations distributed evenly throughout each segment. Ethanol CO2 production was set at 90 percent of plant potential based on nameplate ethanol production volumes derived from Energy Information Agency (EIA) tables.27 Resulting cost estimates were in line with a CO2-EOR industry rule of thumb of about $100,000 per inch-mile (within ±10 percent variation for individual segments, and less than ± 3 percent for networks). Estimating the capital and operating costs for CO2 capture, compression, and dehydration (CCD) from fermenters in an ethanol plant is problematic because of the paucity of publicly available data. There are currently only three commercial-scale ethanol plant operations that process and deliver CO2 via pipelines for injection into geologic targets, two for EOR and the other for saline storage, and capital expenditures (CapEX) and operating expenses (OpEX) are not publicly available for the three privately operated facilities. For this study, we relied on CapEX estimates 26 Environmental Systems Research Institute (ESRI). ArcGIS Desktop: Release 10.5. Redlands, CA. 2017. 27 US Dept. of Energy, Energy Information Administration, 2017, Ethanol Plans (EIA-819M Monthly Oxygenate Report, March 27, 2017. from two DOE-funded projects28,29 and data sourced from a publicly available presentation30 covering a third DOE-funded project, augmented and adjusted by input from trusted sources with direct project experience. A simple linear regression equation was derived by cross-plotting CapEX estimates and ethanol plant size in MGY for the three examples: CapEx ($Million) = 0.15*Plant Size [million gallons per year (MGY)] + 9 Capital costs for 55 and 200 MGY plants are estimated at $17 and $39 million respectively. On a cost per daily-MT of CO2 basis, costs are approximately $43,000 and $26,000 per daily-MT, respectively, for 400 MT per day (55 MGY) and 1480 MT per day (200 MGY). Operating expense for capture, compression, and dehydration from ethanol plants in this study is $8.58 per MT processed. Operating costs are derived from the two DOE final reports24,25 and are applied in a linear fashion for all CO2 volumes. By far, the largest contributor to OpEx is energy costs, which are directly proportional to CO2 volumes compressed. There would be economies of scale for larger-sized plants but these savings could not be quantified from the data available. Both CapEx and OpEx for capture, compression, and dehydration operations deserve significant additional study and refinement, but are considered adequate for this study. For financing purposes, the CO2 capture equipment and pipelines are modeled as 22-year long projects with a two-year construction phase and 20 years of operation and amortization. Two financing scenarios were modeled, one for gathering 4.3 million MT per year of CO2 from 15 ethanol plants, and the other for 9.85 million MT per year from 34 plants, each with two different return on investment (ROI) rates: 10 percent and 15 percent. 28 Integrated Mid-Continent Carbon Capture, Sequestration & Enhanced Oil Recovery Project, final report for DOE Project # DE-FE-0001942, August 31, 2010. 29 Integrated Carbon capture and Storage for North Dakota Ethanol Production, final report for DOE Project # DE-F0024233, May 31, 2017. 30 Ray McKaskle, Trimeric Corporation, Insights into Costs of CCS gained from the IBDP, 2016 Midwest Carbon Sequestration Science Conference, May 17, 2016.
