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). Seasons and times of day. Winter while PM 2.5

Australia Goes All-in on Green Hydrogen

Cars That Think

They’ve been studying up on renewable energy, hydrogen power, and electric vehicles, preparing for the big day in April when their remote-controlled vehicles will rumble for 4 hours in Gladstone, a port city in Queensland. The task: make the most of a 30-watt fuel cell and 14 grams of hydrogen gas. 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

As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. Their results are published in the RSC journal Energy & Environmental Science.

The Case for Nuclear Cargo Ships

Cars That Think

Nearly all of the world’s ship fleet still runs on diesel fuel, with about a quarter of new ships on order being built to run on somewhat lower-carbon alternatives like liquefied natural gas, methanol, or hybrid propulsion. Shipping uses over 300 million tonnes of fossil fuels every year, producing 3 percent of greenhouse gas emissions.

EIA Energy Outlook 2013 reference case sees drop in fossil fuel consumption as use of petroleum-based liquid fuels falls; projects 20% higher sales of hybrids and PHEVs than AEO2012

Green Car Congress

Sales of battery-powered electric vehicles are 65% lower in the AEO2013 Reference case than the year before, with annual sales in 2035 estimated to be about 119,000. Reductions in battery electric vehicles are offset by increased sales of hybrid and plug-in hybrid vehicles, which grow to about 1.3 slower growth in E85 sales.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

They are highly automated production islands that directly convert wind energy to hydrogen, with a few of them processing the gas into fuels and other goods. Airplanes, for example, won’t be able to fly long distances on battery power. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

How Smart EV Charging Will Help Promote Renewable Power Generation

Wallbox

Until recently most power stations relied on coal and gas to power generators. Now countries’ electrical grids are increasingly powered by renewables. With grids increasingly powered by renewables, electrical demand has to follow supply. The EV as a mobile electricity storage device.
