Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). coal, oil, natural gas, and biomass). Winter O 3 increases due to reduced loss via traffic NO x.

Royal Academy of Engineering Report Says EV Success Depends on Low-Carbon Electricity, Universal Broadband Provision and Smart Grids

Green Car Congress

The introduction of electric vehicles on a large scale in the UK can only have a beneficial effect on CO 2 emissions if low-carbon electricity, universal broadband provision and smart grids are in place to support the transition, according to a new report published by the UK Royal Academy of Engineering. Dr Chris Brace, Bath University.

Q&A: Inside DARPA’s Subterranean Challenge

Cars That Think

DARPA designed the competition to advance practical robotics in extreme conditions, based around three distinct underground environments: human-made tunnels, the urban underground, and natural caves. A series of three preliminary circuit events would give teams experience with each environment. IEEE Spectrum. Can you talk about that?

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. Coal- and natural gas-fired power plants are responsible for at least a third of those emissions. Energy Environ. Click to enlarge.

The Case for Nuclear Cargo Ships

Cars That Think

“At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore. Engines in ordinary ships are the size of houses,” says Emblemsvåg, who is leading NuProShip.

Green Hydrogen Cars: How They are Different?

Get Electric Vehicle

Unlike battery-powered electric vehicles, FCEVs can go over 500 kilometers on a full tank of hydrogen and can be refueled in 2-3 minutes, exactly like regular petrol/diesel cars. Unlike Lithium, hydrogen is the most plentiful element in the universe ( Lithium is the key component in electric vehicle batteries).
