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.

U of I study: synthetic fuels via CO2 conversion and FT not currently economically & environmentally competitive

Green Car Congress

A study by a team at University of Illinois at Urbana−Champaign has found that, with currently achievable performance levels, synthetic fuels produced via the electrochemical reduction of CO 2 and the Fischer-Tropsch (FT) process system are not economically and environmentally competitive with using petroleum-based fuel. 6b00665.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. We distinguished ammonium carbamate pairs and a mix of ammonium carbamate and carbamic acid during carbon dioxide chemisorption.

Study finds carbon capture & storage could be financial opportunity for conventional ethanol plants

Green Car Congress

The analysis combines process engineering, spatial optimization, and lifecycle assessment to consider the technical, economic, and institutional feasibility of near-term carbon capture and sequestration (CCS). An open-access paper on the work is published in Proceedings of the National Academy of Sciences (PNAS). —Sean McCoy.

Researchers develop wave-energy-driven CO2 reduction system for production of carbon-based liquid fuels

Green Car Congress

This type of TENG is more cost-effective compared to conventional EMG-based wave energy converters. Finally, besides the above, the cost of fabricating the TENGs must be lowered, and it should be made more convenient to form a large network of TENGs to deliver cheaper and higher wave power output.

Study finds shifts to renewable energy can drive up energy poverty

Green Car Congress

Efforts to shift away from fossil fuels and replace oil and coal with renewable energy sources can help reduce carbon emissions but do so at the expense of increased inequality, according to a new study by researchers at Portland State University (PSU) and Vanderbilt University. —Julius McGee.
