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

The US Department of Energy (DOE) released findings from a new project—Transportation Energy Futures (TEF)—that concludes the United States has the potential to eliminate petroleum use and greenhouse gas (GHG) emissions by more than 80% in the transportation sector by 2050.

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

In a paper published in the journal Energy Policy , the team suggests that more effective policies would evaluate fuels at the refinery level, thereby creating incentives for GHG emissions to be lowered through competition as low GHG emission fuels have higher economic value to blenders. renewable fuel standards—and LCFSs.

UK study finds Bio-SNG could offer 90% reduction in lifecycle CO2; lower cost of carbon abatement than electrical solutions for transport applications

Green Car Congress

Although anaerobic digestion of organic material has been widely accepted as an important renewable energy technology, the production of Bio-SNG will required to move to higher levels of fossil fuel replacement, according to the report. Few other renewable vectors are as fungible, with so few demand-side constraints.

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. The results are reported in an open-access paper in the journal Communications Biology.

However, with the rise in energy prices that began in 2008 and concerns over energy security, there is renewed interest in the conversion technology, the report notes. Researchers also examined whether CTL-conversion plants would use carbon capture and storage technology, which would lower greenhouse gas emissions but create an added cost.
