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.

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.

DOE issues $10M incubator FOA for batteries, power electronics, engines, materials, fuels and lubricants

Green Car Congress

VTO is seeking projects that address the major challenges to developing and commercializing batteries for plug?in in electric vehicles (PEVs). As described in multiple DOE reports, the main barriers to widespread PEV commercialization are the cost; performance and life; and abuse tolerance of high?energy energy batteries.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. The Stanford study considered a future US grid where up to 80% of the electricity comes from renewables. —Barnhart and Benson.

ARPA-E to award $30M for next-gen storage to electrify aviation, rail and shipping: PROPEL-1K

Green Car Congress

Transportation is responsible for approximately 29% of total greenhouse gas (GHG) emissions annually in the United States. Light duty vehicles—passenger and small commercial vehicles—account for 58% of transportation GHG emissions, and battery-powered electric vehicles have emerged as a lower-emissions solution for many applications.

Freudenberg Sealing Technologies and Quantron AG collaborate on fuel cell systems for heavy-duty trucks

Green Car Congress

While battery-electric vehicles can be used efficiently and in an eco-friendly way in urban areas, fuel cell technology offers an attractive approach when it comes to emission-free logistics over long distances and with higher payloads. During stop-and-go traffic or traffic jams, the battery loses significant power.
