NETL CO2U LCA Guidance Toolkit Change Log

openLCA LCI Database

• Added a new profile for saline aquifer transport and storage in addition to multiple biomass and grid mix profiles
• Corrected emissions with an update to the Onshore Conventional Wind Electricity unit process
• Replaced “US Ave Fuel Oil” profile used in the electricity grid mixer
• Corrected flow properties of two water flows to properly convert between kg and m3
• Miscellaneous metadata edits
• Corrected water consumption for power plants

Documentation Spreadsheet

• Updated values to NETL Unit Process Data tab to include correction to Onshore Conventional Wind Electricity
• Old SWRC and Switchgrass profiles are removed
• Added values to NETL Unit Process Data tab to include new grid mix profiles, new biomass profiles, and saline aquifer transport and storage
• Corrected the 45Q Direct+Upstream Impacts factors for transportation to be in units of Mg*km rather than kg*km
• Corrected water consumption for most entries on NETL Unit Process Data sheet

Guidance Document

• Updated text to allow for the use of any upstream CO₂ profile in addition to the NETL default profiles
• Updated text to match new instructions for Contribution Tool (Section 4)
• Minor text updates for grammar and clarity

45Q Addendum to the Guidance Document

• Original 45Q addendum

openLCA LCI Database

• Added GHGRP GWP impact method for use in conjunction with 45Q addendum
• Corrected error in emissions of the natural gas production unit processes
• Added metadata to the NETL Process library

Contribution Tool

• Created “reset calcs” button to clear data but leave built-in calculations
• Minor update to graphing tables format

Documentation Spreadsheet

• Updated values to NETL Unit Process Data tab to include correction to natural gas production profiles
• Added GHGRP GWP results values to NETL Unit Process Data tab to be used in conjunction with 45Q addendum
