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).

Australia Goes All-in on Green Hydrogen

Cars That Think

And while coal plants still supplied over half of Australia’s power in 2021, change is afoot. The government elected last year passed the country’s first climate-action law in more than a decade. Some plans for green ammonia could actually extend fossil-fuel consumption and thus delay climate action. Why a hydrogen truck?

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. Credit: Barnhart and Benson, 2013.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Many countries have met their climate goals and are on track to be completely carbon neutral. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Airplanes, for example, won’t be able to fly long distances on battery power.

How To Make Sure EV Infrastructure Is Energy Efficient

EV Connect

Even among those who support urgent action to fight climate change, there are some who raise questions about the trade-offs that electric vehicles present. But there are serious questions , as well, such as: If electric cars rely on power from coal- or oil-burning plants, are they really reducing fossil fuel use?

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).
