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.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. We hope that it can be a steppingstone for future sustainable solar fuel production.

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.

CARB releases 2022 draft Scoping Plan update

Green Car Congress

The California Air Resources Board (CARB) has released the draft 2022 Climate Change Scoping Plan —the third update to the state’s initial 2008 Scoping Plan. It achieves this goal by building on and accelerating regulations, incentives, and carbon pricing that have been in place for a decade and a half.

Neste opens four new renewable diesel filling stations in California

Green Car Congress

Each location is regularly supplied with Neste MY Renewable Diesel, a low-carbon fuel produced from 100% renewable and sustainable raw materials that cuts greenhouse gas emissions by up to 80% compared to petroleum diesel. The four new fueling stations join existing Neste-branded fuel stations in San Leandro, San Jose, Keyes and Ripon.

JBEI researchers produce high density jet fuel precursors from bacteria

Green Car Congress

Among these biofuel candidates, C 10 and C 15 terpenes (monoterpenes and sesquiterpenes) have been increasingly used as jet fuel alternatives for commercial aviation and military purpose because of their structures, suitable carbon numbers and reactive olefin functionality, which collectively impart low freezing points and high energy densities.

Study finds renewable fuel mandates alone not likely to lower carbon intensity of biofuels; the importance of localized LCAs and optimized low carbon fuel standards

Green Car Congress

Ultimately, the authors suggest, states can encourage the reduction of fuel GHG emissions by developing policies, such as a low carbon fuel standard (LCFS), that encourage incremental improvements in corn ethanol in the short term and in the medium term by switching to cellulosic-derived fuels. —Boies et al.
