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.

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

Our test shows that as well as electric driving on renewable electricity, there are other concepts that permit long-distance, low-emission driving. As a result, the synthetic fuels assure a more effective mixture preparation process, cleaner combustion and lower emissions.

Synbio company Intrexon and Dominion partner to commercialize bioconversion of natural gas to isobutanol in Marcellus and Utica Basins

Green Car Congress

Intrexon’s proprietary methanotroph bioconversion platform uses optimized microbial cell lines to convert natural gas into higher carbon compounds such as isobutanol and farnesene under ambient temperatures and pressures. Methanotrophic bacteria oxidize methane as their sole carbon source to support cellular metabolism and growth.

Ninth annual Green Innovation Index finds California light-duty vehicle emissions spike; major challenge to 2030 climate goals

Green Car Congress

However, although the state has made considerable progress decoupling economic growth from greenhouse gas (GHG) emissions, the rate of emissions decline appears to be slowing, due in part to a spike in transportation emissions attributed to an increase from light-duty vehicles. —Adam Fowler, economist at Beacon Economics.

Top Factors Affecting EV Adoption

EV Connect

Industry experts predict that electric vehicles (EV) will account for 40% of car sales by 2030. Yet for all the optimism around the electric vehicle adoption rate, certain human, structural and environmental factors still dictate the pace. Of the 289 million cars registered on US roads, barely 2 million are electric.

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. China recently launched several EV demonstration programs (e.g., Earlier post.]
