ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas. This results in significantly lower battery production emissions than in earlier studies.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses. However, residential uses and exports of natural gas were not considered in those comparisons.

Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

In the Tianjin study, they team fueled a four-cylinder light-duty diesel engine fueled with CFT and DF, identifying 13 individual carbonyl compounds in the exhaust. However, the use of CFT resulted in a remarkable reduction in carbonyl emissions in comparison with using DF. Jakober, 2008). reduction in total carbonyls and a 6.0–100%

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. The study used the series production versions launched in 2011, with the assumption of operation for 150,000 km (93,205 miles). dCi); gasoline Fluence 16V (1.6L); and the battery-electric Fluence Z.E.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)
