How Efficient Is Your EV? It’s Complicated

Cars That Think

But the efficiency equation is more complicated than that because, unlike petrol pumps, recharging stations do not transfer energy perfectly. The car will then know how much electricity was consumed, along with how much of that its batteries managed to store.

Why Hydrogen power is not the answer

EV Info

I truly believe hydrogen is the UK’s best opportunity to build a world-leading industry which creates UK jobs, cuts emissions and is the envy of the globe.” Most of today’s hydrogen use is grey; Blue: during the steam reforming process, a high proportion of carbon generated is captured and stored underground. And here’s why. .

Naysayer Alert – the hydrogen red herring

My Electric Car

More significantly it must be realized that hydrogen, just like a battery, is not an energy source in itself, but simply a means of storing energy. Most commonly it is refined from conventional coal seam gas, often termed ‘natural gas’ to greenwash what it really is, in essence just methane found with other fossil-fuel deposits.

Why EVs Aren't a Climate Change Panacea

Cars That Think

Greenpeace , on the other hand, argues that sales of all diesel and petrol vehicles, including hybrids, must end by 2030 to meet such a target. In states (or countries ) with a high proportion of coal-generated electricity, the miles needed to break-even climb more. For the U.S. Doing so would still take decades to complete.

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. Furthermore, unlike coal and oil, it is a clean energy source that produces only water vapor and leaves no residue in the air. Why Fuel cells are Preferred?

Electric Cars and a Smarter Grid - Green Inc. Blog - NYTimes.com

Tony Karrer Delicious EVdriven

And in a true smart grid, electric cars will not only be able to draw on electricity to run their motors, they will also be able to do the reverse: send electricity stored in their batteries back into the grid when it is needed. An embryonic movement is growing in Europe to build “smart cities&# that will challenge the status quo.

Small long-term evaluation program, including modeling of vehicle-to-grid building benefits and economics, begun with Southern California Edison, joined by EPRI, other utilities, US DOE. DaimlerChrysler has presented plug-in hybrids in commercial vans that have enough room to store the batteries, but the technology is not quite ripe for cars."Plug-in
