One tax credit allows clean fleets to recoup 50 cents per gge (gasoline gallon equivalent) specifically for the alternative fuels propane autogas (LPG), compressed natural gas (CNG) and liquid natural gas (LNG). The other provides a 30 percent credit on fueling infrastructure for any alternative fuel, on up to $30,000 per facility.

Though propane autogas is already affordable for fleets to implement without federal funding [see our recent post “America’s most cost-effective and practical clean fuel succeeds despite lack of government support”], this is still great news in terms of encouraging the use of domestic alternative fuel in the U.S. transportation sector. Fleets that have already made the transition to clean fuel will recoup enough money to add even more alt fuel vehicles over the next year. For fleet operators that have thought about converting to an alternative fuel but worried about the upfront cost, these tax credits may just be the extra incentive (pardon the pun) they need to take that first step toward greening their vehicles and saving on fuel costs in the long run.

If you’re a fleet operator considering making the switch to alternative fuel in 2013, we encourage you to do your research to decide on the most practical fuel for your fleet. The Alternative Fuel Fact Briefs available on the Autogas for America website provide a side-by-side comparison of propane autogas versus natural gas electric vehicles and gasoline, so you can see how each fuel stacks up in the areas of cost, emissions reduction and overall viability.

Here’s to a greener 2013 for American fleets—happy saving!

Mark Perry, Nissan’s director of product planning, said, “If fast charging is the primary way that a Leaf owner recharges, then the gradual capacity loss is about 10 percent more than 220-volt charging. In other words, it will bring the capacity…closer to 70 percent after 10 years.”

The same article also states that an average Lithium-Ion battery cell in an electric cycle has about 1,000 full cycles before it is classified as reaching its “end of life” (EOL).  If you fast charge your Leaf more than twice a week, however, the battery’s EOL could arrive much more quickly. Since the lifespan of the battery is determined by a fixed number of charge cycles, more frequent charging effectively ‘uses up’ battery capabilities more quickly.

According to the industry, a battery has reached its EOL after it has lost 20 percent of its original storage capacity, meaning a charging capacity of 80 percent, which occurs in about 10 years without frequently fast charging an EV.

With all the expenses of electric vehicles (and they seem to be making them more expensive over time), the cost of a replacement battery brings yet another cost into the mix if you want your EV to keep running. In fact, according to a recent British article, it could cost you up to £19,000 to purchase a new battery pack, which would be about $30,645 in U.S. dollars. Indeed, Nissan has stated the production costs for a replacement Leaf battery are around $18,000 – but has declined to say on its website how much a replacement battery would cost the consumer.

And it seems other automotive buffs are questioning the viability of the Leaf’s battery. As Daryl Siry wrote in a blog for Wired.com:

“It also appears that Nissan has cut corners on the most critical aspects of electric vehicle technology – the battery pack.”

One of the more noticeable traits – maybe because it is not so noticeable – of an EV is that they produce almost no sound. However, due to concerns over safety, companies such as Warwick Manufacturing Group are designing and testing sounds to be added to EVs.

“Electric vehicles and hybrids are alarmingly quiet,” said Warwick’s Paul Jennings. “The concern is that as a road user, as a pedestrian or as a cyclist, we’re just not aware of their presence. And therefore there’s a real danger that there could be an accident.”

Jennings further explained that sounds they are testing range from regular “car” noises to sounds from “The Jetsons.” Once they have a noise, they test them in their car, named Elvin.

Clotaire Rapaille, consultant for the automotive industry, thought this idea sounded like music to her ears.

“Think of all the possibilities that are suddenly open,” she said. “We have different ring tones for different cell phones; we can have different sounds for different kinds of cars.”

While safety is important, noise emissions shouldn’t be the only thing that electric vehicles are worried about. In an article published on the American Fuel Facts blog, we describe how EVs may be worse for the environment than gasoline vehicles when energy-sapping batteries are factored into the equation.

Zero-noise and zero-emissions both sound nice, but it looks like neither may turn out to be in our future.
