GHGenius 5.02c

GHGenius 5.02c is a minor version release. 

Microsoft has recently been rolling out changes to how Office handles macros in files downloaded from the web. Depending on your version of Office, you may need to take new and extra steps to allow the macros in GHGenius. Microsoft has provided a page with many details on this change, and most users will need to follow these steps to allow macros.

Full changelog is after the break.

Changelog:

  • Changes to the biodiesel pathway.
    • The fossil C in the methanol is now included in the exhaust emissions for biodiesel rather than in adjustments to the co-product credits. This aligns the approach with the ECCC LCA Model.
    • There are additional biodiesel co-products included:
      • Distillation Bottoms
      • Free fatty acids
      • The emission displacement factors for refined, crude, and fuel applications for glycerine have been changed to reflect changes in the marketplace over the past twenty years. The refined and crude factors are lower and the fuel factor is higher as the fossil emissions are not accounted for in exhaust emissions.
      • The emission displacement factor for propylene glycol is slightly lower reflecting new data on the production from fossil resources.
    • c. Biodiesel CIs will be higher for most co-product applications with the new version.
  • The potential for including CCS in the HDRD pathway has been included on the sequestration page in response to user requests. The input is slightly different than other pathways as the quantity of CO 2 sequestered needs to be calculated outside of the model and input into the model as it could be biogenic or fossil CO 2 . The energy requirements are input as with other sequestration pathways.
  • Bug fixes
    • The transportation emissions for wet feedstocks are treated consistently and the double counting of some feedstock moisture contents has been removed.
    • Issues with energy and mass allocation for coproducts from the production of gaseous fuels has been corrected.
    • An issue with ethanol co-products being slightly influenced by biodiesel yield has been removed.
    • CCS for RNG has been simplified so that the reduction shown in row 38 on the sequestration sheet will be the emission reduction on the Upstream Emissions HHV sheet.
    • The e-fuel pathways have been modified to correctly handle the cases where it is fossil-based CO2 that is processed. CO2 excess to process requirements is included in process emissions and the remainder of the carbon in the CO2 is embedded in the fuel so the fuel combustion emissions are the same as a fossil fuel.
