Heavy Lift: Ethanol's Role in Decarbonizing Heavy Duty Markets

Transcript

1. 1 We are trying to reduce CO2 in the atmosphere, not at the tailpipe Global Carbon Project 2022 2021 US GHG ~ 6.3 Gtons US Transport ~ 1.8 Gtons (~ 5% of global emissions) 2040 2060 2080 CO2 pathways using IPCC Remaining carbon budgets
2. 2 FUEL VEHICLE Raw material Components Assembly In-use (Regulated today) Maintenance Export Recycle Disposal Life-Cycle Analysis Land-use change Impact on environment CO2 capture Impact on market OTHER Production (Regulated through RFS) Transport Fueling

4. 4 A “plug” for ClearFlame Pairing an engine with renewable fuel Base image from Cummins X15 service manual 10-15% of engine parts changed Fuel adaptive Fleet GHG & $$ savings Based on 10K mi fleet testing • Total WtW GHG reduced*: 45% • Total tons avoided annually by each 100,000 mile/truck: 64.3 tons per truck • Fuel cost saved over 10,000miles: $2,350 * Based on Greet Model 2.0 Same performance as base diesel Lower criteria pollutants Soot emissions below limit w/o DPF PM limit EO Soot Integrates as new product or retrofit
