UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

Total hydrocarbons (THC), non-methane hydrocarbons (NMHC), and carbon monoxide (CO) showed either marginally or statistically significant reductions for E15. Although no strong differences were found for carbon dioxide (CO 2 ) emissions, E15 showed lifecycle greenhouse gas (GHG) emissions savings when compared to E10. Durbin, Kent C.

Proposed CA LCFS pathways for corn starch ethanol with carbon capture and sequestration: as low as 37 gCO2e/MJ

Green Car Congress

North Dakota-based Red Trail Energy (RTE), which since 2007 has operated an ethanol production facility with annual production of about 60 million gallons per year, is proposing sequestration of CO 2 produced from starch fermentation to lower the overall carbon intensity of the fuel for the California Low Carbon Fuel Standard (LCFS).

California ARB issues feedstock-only pathway for camelina-based fuels under LCFS; zero ILUC emissions results in very low CI fuels

Green Car Congress

a wholly owned subsidiary of Global Clean Energy Holdings, a feedstock-only pathway for the production of camelina-based fuels under the Low Carbon Fuel Standard (LCFS). The feedstock-only CI (carbon intensity) is 7.58 As a comparison, ARB’s general pathway for soybean-based biodiesel finds a direct GHG contribution of 21.25

Life Cycle Analysis of Camelina-based Renewable Jet and Diesel Fuels Shows 84-89% GHG Savings Compared to Petroleum Fuels

Green Car Congress

The study was based on camelina grown in Montana by Sustainable Oils and processed into renewable jet and diesel fuels using UOP hydroprocessing technology. It is estimated that the state of Montana alone could support between 2 and 3 million acres of camelina, generating 200 to 300 million gallons of oil each year. Earlier post.).
