U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.

California Air Resources Board readopts Low Carbon Fuel Standard, adopts regulation on alternative diesel fuels

Green Car Congress

1 ] The average carbon intensity requirements for years 2011 and 2012 reflect reductions from base year (2010) CI values for CaRFG (95.85) calculated using the CI for crude oil supplied to California refineries in 2006. [ 3 ] In 2015 the LCFS was readopted and the CI modeling updated. Alternative Diesel Fuels.

Farm-to-Fleet venture to make drop-in biofuel blends part of regular operational fuel use by US military

Green Car Congress

The Navy will seek to purchase JP-5 and F-76 advanced drop-in biofuels blended from 10 to 50 percent with conventional fuels. The announcement marks the first time alternative fuels such as advanced drop-in biofuels will be available for purchase through regular procurement practices. —Navy Secretary Ray Mabus.

ICCT: available low-carbon fuels can reduce CI of on-road transportation fuels in Pacific Coast region by 14%–21% by 2030

Green Car Congress

Fuel carbon intensity reduction from 2015-2030 from fuel deployment scenarios for the Pacific Coast region. The study presents eight scenarios for low-carbon fuel supply, including varying amounts of electricity, hydrogen, ethanol, biodiesel, renewable diesel, next generation cellulosic biofuel, and natural gas.

euglena planning commercial production of biojet and renewable diesel from algae in Japan

Green Car Congress

The company has been investigating the production of biojet from the microalgae Euglena since May 2010 ( earlier post ) and has also partnered with Isuzu in research on next-generation (i.e. crop oils and animal fats) to non-ester biofuels—renewable fuels that are pure hydrocarbons indistinguishable from their petroleum counterparts.

NRC report concludes US LDVs could cut oil consumption and GHGs by 80% by 2050; reliance on plug-ins, biofuels and hydrogen; strong policies mandatory

Green Car Congress

Achieving those goals will will be difficult—but not impossible to meet—and will necessitate a combination of more efficient vehicles; the use of alternative fuels such as biofuels, electricity, and hydrogen; and strong government policies to overcome high costs and influence consumer choices.
