Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Study finds air pollution and GHG costs of crude-by-rail nearly 2x pipeline costs; much larger than spill and accidents costs

Green Car Congress

Researchers from Carnegie Mellon University and the University of Pittsburgh have found that the air pollution and greenhouse gas costs of shipping crude by rail are nearly twice as large as those for oil pipelines. Air pollution and greenhouse gas damages for transportation by railroad and pipelines to the gulf coast.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

NTSB Chair questions safety impact of heavy EVs

Green Car Congress

During a keynote speech to the Transportation Research Board annual meeting Wednesday, National Transportation Safety Board (NTSB) Chair Jennifer Homendy questioned the safety impact of electric vehicles. The Ford F-150 Lightning is between 2,000 and 3,000 pounds heavier than the non-electric version. Why does this matter?

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Abatement cost with hydrogen at $1/kg (7.4/MMBtu).

CMU study finds taxes on emissions would result in more rapid electrification by ridesharing companies

Green Car Congress

Researchers at Carnegie Mellon’s College of Engineering have found that with an emissions-based incentive towards electrification, ridesourcing companies such as Uber and Lyft would electrify more and cut their emissions by amounts ranging from 10% in New York to 22% in Los Angeles. —Bruchon et al.

What makes maintaining electric vehicle charging stations more difficult than gas stations?

Setec Powerr

Electric vehicles are gaining popularity as people become increasingly concerned about the environment and rising fuel costs. While electric cars have many benefits, such as reduced emissions and lower fuel costs, they also present unique challenges when it comes to maintaining the charging infrastructure they require.
