**Addition of biomass feedstock net import supply curves**
- New commodities(IFG stands for imported FOG, ICL stands for imported canola oil, HIF stands for biofuel produced through HEFA of imported FOG, HIC stands for biofuel produced through HEFA of imported canola oil, IMP stands for imports, _C is a new location that refers to customs entry point. The rest of the nomenclature follows that of other commodities in the model) - New activities: (IFG stands for imported FOG, ICL stands for imported canola oil, HIF stands for biofuel produced through HEFA of imported FOG, HIC stands for biofuel produced through HEFA of imported canola oil, _C is a new location that refers to customs entry point. The rest of the nomenclature follows that of other activities in the model) - Supply curve parameters for the new curves using the reference quantities, reference prices, and elasticity assumptions (new Data_Inputs spreadsheet: bmassmx_refdata.csv) - Input distances and costs for transportation routes between ports of entry and biorefineries (routes must originate in states that are points of entry for the imports; allowed routes are up to 1000 miles) - Entries in the TEA/LCA/policy input spreadsheets going into the data_inputs folder of the model repository: CO2eqcoeffs.csv, IRA_taxcredits.csv, state_SAF_tc.csv, IOcoeffs, OMC.csv, CI_delta_LC_energy, bioref_energy_input_q.csv, LCFS_AMIXT_MJpergal_all.csv, AMIXT_CI_LCFS_all.csv - Add inputs to determine incentive eligibility of biofuels produced from the imported feedstocks: - For 45Z credits, according to changes introduced in the OBBBA, eligibility is limited to biofuel produced with feedstocks from Canada, U.S., or Mexico - RFS-SET2 (still not approved) proposes that biofuel produced with imported feedstocks would get half the RINs and the same biofuel produced with domestic feedstock - New equation CTRANSPEQ_CB to track transportation cost of moving the imported feedstock from the customs entry point to the biorefinery - Interstate transportation costs for the imported feedstocks are tracked as part of the CXM equation **Addition of SAF export demand curve from European Union** main.gms - New commodity (SAF_EXP_T) and commodity subgroup for commodities with export demand curves (CEXPT(C)) - New activity: EXP_SAF_T - New parameters: - SAF_EU_ref_imp_share: Share of projected EU (biomass-based) SAF volume required to meet ReFuelEU blending mandate used as reference quantity for potential U.S. exports - SAF_EU_max_imp_share: Maximum share of projected EU SAF (from biomass) volume required to meet ReFuelEU blending mandate allowed to be met potential U.S. exports (this is a modeling assumption, not a real world limit; however, it is reasonable to think that EU will develop capacity to meet a large share of the mandates) - SAF_JET_EU_premium(T): Assumed premium for SAF (over conventional jet fuel) that EU countries are willing to pay to meet ReFuelEU blending mandate in period T - USGC_EU_cleantanker_freight_rate: cost of transporting SAF from U.S. Gulf Coast to EU - Demand curve coefficients for exported commodities data.gms - New input-output relationships in IOCOEFF table (except for the corn ethanol ATJ pathway and HEFA using soybean oil or imported canola oil, all other SAF has now two options at the wholesale fuel terminal: 1) distribution to domestic airports, 2) export to the EU) - New Table DD_BLF_INTERNATIONAL containing data on international biofuel demand that could be met by U.S. biofuel - Added elasticity value for export demand curve to parameter set DELAST(CDEMP)
