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 is especially important for assessing the GHG emissions of PHEVs.

Hydrogen is not currently an option for small vehicles such as electric scooters and motorcycles, since the pressure surge during refilling would be too great. POWERPASTE (left); POWERPASTE cartridge (middle); portable 100 W power supply unit (right). POWERPASTE, on the other hand, the researchers suggest, would be ideal.

CMU analysis finds BEVs powered with natural gas-based electricity have about 40% of the lifecycle GHGs of a conventional gasoline vehicle

Green Car Congress

According to a new lifecycle analysis by a team at Carnegie Mellon University, a battery electric vehicle (BEV) powered with natural gas-based electricity achieves around an average 40% lifecycle greenhouse gas (GHG) emissions reduction when compared to a conventional gasoline vehicle. Earlier post.).

EPA annual inventory shows US GHG up 3.1% from 2017-2018

Green Car Congress

This increase was largely driven by an increase in emissions from fossil fuel combustion, which was a result of multiple factors, including more electricity use greater due to greater heating and cooling needs due to a colder winter and hotter summer in 2018 in comparison to 2017. Source: EPA. >.

MIT study finds shift to green energy sources could mean crunch in supply of key rare earth elements

Green Car Congress

Comparison of demand projections for REE (total summed). Of particular significance, one country (China) controls 98% of current supply (production). For example, in 1978 Zaire controlled 48% of the cobalt supply and yet political unrest in Zaire resulted in a disruption to global supply that became known as the “Cobalt Crisis”.

Dark Secrets at The Heart EV Supply chain We Often Fail to Address

Get Electric Vehicle

We all believe that an electric vehicle is much more eco-friendlier than a conventional gasoline car. Yes, They Are Greener But… On the surface, EVs are more ecological than gasoline cars because 70-80% of the pollution caused by automobiles comes from their tailpipe and EVs don’t have tailpipe emissions.

DeCicco: Transportation GHG reduction policy should focus upstream on fuel supply rather than downstream on choice of fuels in vehicles

Green Car Congress

In addition to managing travel demand and improving vehicle efficiency, the implied climate policy priority is limiting net GHG emissions in fuel supply sectors. ” The challenge is illustrated for electric cars, which are roughly three times as fuel efficient as conventional, non-hybrid gasoline cars.
