Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle.

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.

UC Davis researcher finds ride-hailing EVs offer triple the emissions benefits of a personally owned EV

Green Car Congress

Replacing a gasoline-powered ride-hailing vehicle with an electric vehicle can deliver three times the carbon benefits of a personally owned electric vehicle, according to a study by a University of California, Davis, researcher of Uber and Lyft data. The paper is published in the journal Nature Energy.

Study calls for reduction in car ownership, battery size and vehicle dependency to limit environmental impact of surging lithium demand

Green Car Congress

The authors designed a material flow analysis paired with socioeconomic pathway modeling to determine possible scenarios for the decarbonization of personal transportation in the US. Producing EVs and building and maintaining roads, highways, and parking lots are energy- and emissions-intensive processes with high levels of embodied carbon.

The Role of Power Utilities in Turning EVs into a Grid Asset – Part 2

Driivz

Part 1 of this two-part blog discusses the challenges facing electric utilities – both electricity generators and grid operators – with electric vehicle (EV) adoption coinciding with the electrification of buildings, heating, and industry. That is one way to balance the load on the grid. Leveraging EVs as grid assets.
