US Navy researchers demonstrate synthesis of high-density biofuels from myrtenal using cyclopropanation

Green Car Congress

Recent work has shown that chemoselective hydrogenation of ring-strained monoterpenes is an effective strategy for the generation of high-performance fuels. Alternatively, the alkenes can be easily converted to cyclopropane rings, which further enhances the density and volumetric heat of combustion (NHOC) of these hydrocarbons.

Opinion: Alternatives to the RFS

Green Car Congress

Recently, the Energy Resources Center made headlines by saying the EPA’s shift on the Renewable Fuel Standard (RFS) would equal adding 1 million more passenger vehicles on the road. It’s also a political lightning rod given the stagnation of fuel consumption matched with accelerating ethanol blending. by Doug Williams.

Study finds behavior-influencing policies remain critical for mass market success of low-carbon vehicles

Green Car Congress

Policies to entice consumers away from fossil-fuel powered vehicles and normalize low carbon, alternative-fuel alternatives, such as electric vehicles, are vital if the world is to significantly reduce transport sector carbon pure-emissions, according to a new study. —McCollum et al. —David McCollum.

NAIT partnering with Oberon, Mack and Westcan to advance use of DME fuel in long-haul trucks

Green Car Congress

Oberon units have the capacity to produce 10,000 gallons of DME per day to service regional fuel markets. Because DME can be produced from natural gas, its use could provider another value-added product from Alberta’s resources. Rebecca Boudreaux, President, Oberon Fuels. billion by 2020.

MIT study concludes that absent climate policy, coal-to-liquids could account for around a third of global liquid fuels by 2050

Green Car Congress

They modeled different scenarios, varying the stringency of future carbon policies, the availability of biofuels and the ability to trade carbon allowances on an international market. However, the viability of CTL would be highly limited in regions that adopt climate policies, especially if low-carbon biofuels are available.

DOE TEF project finds US can eliminate petroleum and reduce GHG by more than 80% in transportation by 2050; less use, more biofuels, expansion of electricity and hydrogen

Green Car Congress

TEF is organized into four research areas: light-duty vehicles; non-light-duty vehicles; fuels; and transportation demand. Findings are being detailed in a series of nine reports, six of which are now available. Achieving the reduction will require combined reductions across three factors: modes, demand and fuels.

UC Davis report finds LCFS compliance costs may rise rapidly; recommends offsetting measures

Green Car Congress

Due both to the unprecedented nature of the program as well as to the uncertainty regarding the ability of the renewable fuel industry to produce volumes of low CI fuels necessary to meet the required reductions, it is difficult to predict market outcomes and compliance scenarios in the market in coming years. —Lade and Lin.
