The annual Alternative Clean Transportation Expo is being held in Washington D.C. this week, where movers and shakers in the alternative fuel and fleet industries will gather to share knowledge about the latest clean technologies and trends. This year’s expo is notable because it’s kicking off today with a 2pm event sponsored by the Propane Education and Research Council called “Lead the Way: A Propane Autogas Event.” What better way to commence a gathering of the nation’s leading authorities on alternative fuel and transportation than to put the spotlight on the most viable fuel for fleets?

Propane autogas is the most widely used alternative fuel in the world, powering more than 21 million vehicles globally. The “Lead the Way” autogas event will cover refueling infrastructure pitfalls, how switching vehicle fleets to autogas can benefit taxpayers, insight on financing for alternative fuel fleet programs and more. Policymakers and public and private fleet managers are encouraged to attend to learn more about autogas, the most viable fuel for fleets.

Autogas for America founder Stuart Weidie will speak during the ACT Expo on Wednesday, June 26, during a 3:30pm panel called: “Fueling the AFV Revolution: Updates on Rapidly Expanding AFV Infrastructure Networks across North America.” His presentation, titled, “The Cost-Effectiveness of Propane Autogas Refueling Infrastructure, Present and Future,” will provide expert insight on just how affordable and easy it is for fleets to get up and running on propane autogas, with a focus on building autogas fuel stations. (For example, did you know it can be 15 times more expensive to build a CNG fuel station vs. an autogas station?) In fact, infrastructure for natural gas is so cost prohibitive, some even wonder if it will ever really catch on with more American drivers.

A variety of propane autogas vehicle technology will be on display during the ACT Expo, which runs June 24–27 at the Walter E. Washington Convention Center in Washington, D.C. ROUSH CleanTech will showcase a propane-powered Ford F-650, CleanFUEL USA will display a GM 4500 chassis and PERC will have a Liberator 6.0-liter engine, as well as autogas dispensers.

In addition to propane autogas, the Alternative Clean Transportation (ACT) Expo represents all alternative fuel types on the market, including electric, hybrid, hydrogen, natural gas, and renewable fuels. As North America’s largest alternative fuel and clean vehicle technology conference and expo, the ACT Expo provides direct access to the latest OEM and technology products, offering a one-stop shop for fleet managers to learn about the wide-range of solutions available.

As more U.S. drivers move toward alternative fuel and advanced technology vehicles instead of gasoline, several state governments are tackling an important question: how do we pay for transportation infrastructure funded by diminishing gasoline taxes while not punishing those who opt for cleaner transportation?

No one is a fan of raising taxes, whether it’s the gasoline tax or fees for alternative fuel vehicles, but we can no longer depend on the gasoline tax to fund our nation’s transportation needs. On one hand, this is a good thing; it means we’re decreasing our reliance on gasoline for vehicle fuel and increasing our nation’s energy security. On the other hand, the money has to come from somewhere—and it’s becoming increasingly clear that taxing drivers of alternative fuel and advanced technology vehicles is not the answer. Part of the allure of switching to alternative fuel or purchasing an electric vehicle is the promise of eventual cost-savings, and any move to tax these drivers is sure to be met with resistance.

The state of Virginia, for example, has legislation approaching ratification that would replace the gasoline tax of 17.5 cents per gallon with a 3.5 percent wholesale tax on motor fuels and a $64 annual fee on hybrid and alternative fuel vehicles (down from $100 as part of a compromise). While this was meant as a way for clean vehicle drivers to continue contributing to the state’s transportation fund, some criticize the so-called “hybrid tax” as detrimental to adoption of clean fuel vehicles, petitioning the legislature to eliminate the tax from the bill.

Other states struggling to address transportation funding in the new era of alternative fuel and fuel-efficient vehicles include IndianaMaryland, and New Jersey. In Florida, a group is proposing to tax drivers for every mile they drive in order to make up for an estimated $74 billion shortfall in funding for necessary transportation projects. West Virginia is considering a similar program; however, Minnesota recently tried this and found the tracking technology lacking. Even the federal government is grappling with the question of how to increase funding for important transportation initiatives without raising taxes. However, as an article in Politico recently pointed out:

The most obvious, simple and straightforward solution would be to raise the 18.4-cents-per-gallon gasoline tax, which hasn’t budged since the last time it was raised in 1993. But that’s also the most politically difficult option. As a result, a gas tax increase has become the third rail of transportation policy, sending lawmakers of all political stripes — Democrats as well as Republicans — fleeing.

We are certain to see this issue played out on both the state and national level. Solutions will most likely be a matter of trial and error as part of the growing pains of collectively switching to domestic clean fuel. Luckily for drivers of vehicles that run on affordable American-made fuels like propane autogas, fuel cost savings are significant and, in many cases, immediate. While a $64 fee may negate any savings a driver of an electric-hybrid vehicle sees in a year, autogas vehicle drivers can save thousands annually on fuel costs alone.

Electric vehicles (EVs) have recently attracted significant attention from the media, politicians, and environmentalists, but do EVs really live up to everything their manufacturers promise? Autogas for America released a new Alternative Fuel Fact Brief on November 25, examining the evidence behind the industry’s claims that EVs are viable, cost-effective and “zero-emission.”

The study questions electric vehicle’s environmental record, considering the greenhouse gases emitted during EV manufacturing. It points out that while EVs have no tailpipe emissions, they charge on U.S. electric grids that draw 50 percent of their power from coal. The Fact Brief also casts doubt on the practicality of EVs for public and private fleets, citing the technology’s struggles with limited carrying capacity, limited driving range and the high cost of their charging infrastructure. The study warns that experts believe an increase in EVs could overburden an already strained electric grid.

While electric vehicles hold many benefits over vehicles running on traditional fuels, the Fact Brief encourages consumers to consider other alternative energies which have more verified environmental and economic benefits and a proven record in American fleets.

Currently, the car with the best gas mileage reaches about 50 miles a gallon. So, it came as a huge shock to the automotive industry when General Motors announced last year that their new electric-drive Chevy Volt would reach an EPA-rated 230 miles per gallon. But so far, journalists, industry experts and even the EPA are still at a loss to fully explain GM’s math.

The Chevrolet Volt is a plug-in hybrid electric vehicle, designed to run on electricity until its battery level drops. After that, a gasoline engine kicks in to power the car. According to GM, the Volt’s battery-only range would be about 40 miles, and the gasoline engine would have about 40 mpg.

How did GM reach this inflated figure? According to Motor Trend, GM used a proposed EPA measurement system that converts a vehicle’s kilowatt hours (kWh) to an equivalent in miles per gallon. Since GM predicted the Volt would consume 25 kWh per 100 miles, they calculated 230 miles per gallon. The EPA has since shied away from GM’s claims, officially rating the Volt at 37 kWh per 100 miles and announcing it had “not tested a Chevy Volt and therefore cannot confirm the fuel economy values claimed by GM.”

Journalists questioned the 230 mpg claim because the actual figure can change drastically depending on how the Volt is driven. For instance, CNN predicts that if a driver goes 300 miles with a fully charged battery, the fuel economy would actually be about 62.5 mpg. Edmunds.com found that with the battery depleted the car averaged 31.1 mpg.  Edmunds ultimately called the Volt’s performance “seriously subpar when compared to the mid-40s mpg that a standard hybrid typically provides.”

Analysts say GM’s figures also overlook recharging and initial costs. GM has said 8 kWh are needed to travel 40 miles, which the Department of Energy says will cost around 88 cents per charge. While these costs may appear modest, reviewers like Edmunds.com question the overall value since the Volt is far more expensive than other hybrids.

Ultimately, GM and other EV manufacturers need to justify the high price tag of their vehicles by providing buyers measurable fuel savings and a return on their investment. But, even the CEO of GM has questioned the Volt’s lasting value, saying it will be “an old, old technology and old news” in just five years.

According to a new study by psychologists at Germany’s Chemnitz University of Technology, drivers who regularly worry about an electric vehicles’s (EV) battery level don’t maximize their vehicle’s potential. The study found that worried drivers overcharged their EVs on a regular basis. However, the study didn’t address how overcharging can lower the vehicle’s battery life and potentially strain electric grids.

Feeling like you’re about to be stranded because your car runs out of juice is known as “range anxiety” in the EV business. The study at Chemnitz found drivers experienced range anxiety about once per month, and researchers proposed that feeling could worsen if there were no nearby public charging stations. EV manufacturers have long tried to dismiss consumers’ worry about insufficient mileage between charges. Then again, when new battery-electric cars like the Nissan Leaf lose power unexpectedly, range anxiety may be well founded.

The researchers discovered most drivers needlessly recharged their vehicle with 20 percent or more power left in the battery. This finding is important because frequent charging can overwhelm the electric infrastructure, which is already threatened by electric vehicles.

Experts estimate that EVs consume about a third of the power of a house, and warn that adding electric cars to a residential area could overwhelm transformers and even cause blackouts. A public charging network would ease drivers’ nerves, but would add an additional burden to the grid. EVs draw their power from a system that is not prepared to meet the increased demand.

Overcharging can also degrade EV’s battery at a higher rate. Fast charging a Nissan Leaf, for example, can decrease the battery life much faster than slow charging at home. And, replacing a dead EV battery isn’t cheap: a recent article from the UK states that a new battery pack could cost over $30,000.

With the harm overcharging can ultimately bring to their vehicles and the electric grid infrastructure, EV drivers unfortunately have more to worry about than just their range.

nissanleafIf you fast charge your Nissan Leaf more than once per week, you could see a decrease in your vehicle battery life by several years.

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.”

A recent British study has questioned the environmental benefits of plug-in electric vehicles (PEVs) and has gone so far as to claim they may be dirtier than gasoline vehicles. While this statement may baffle those who have seen automakers’ touting “zero emissions” EVs (view our June 2nd post about Nissan), the study goes on to say that nearly half of an electric vehicle’s emissions are produced during the manufacturing process, before the car has ever been driven. EVs require multiple batteries to operate – batteries that greatly increase the amount of energy needed and pollution created by the factory.

Of course, the other portion of EV emissions is created when the vehicle’s battery is charging. Since much of the world’s electricity is sourced from dirty sources such as coal, the EV’s emissions are simply being transferred from the road to the area around the power plant.

One place this study’s findings might be (indirectly) tested is in Australia where PEV manufacturer Tesla is attempting to break the national record for the longest road trip by an electric vehicle with its all-electric “Roadster.” It will be recharged along the way with renewable energy sources such as solar, hydro and wind to illustrate the low emissions capabilities of the vehicle. Critics of the project, such as automotive expert and editor of New Zealand’s sardonic Dog and Lemon Guide Clive Matthew-Wilson, say that the car isn’t as environmentally conscious as Tesla would have you believe. “Burning coal to make electricity to power an electric car creates more pollution than if you simply powered the same vehicle using petrol [gasoline],” Matthew-Wilson said.

This study was among the first to complete an analysis of  the energy-intensity of producing batteries when calculating EV life-cycle emissions. Given that this and other recent studies have targeted EVs’ green credentials lately, shifting from gasoline to mass production of EVs may be too ambitious for now – which only furthers the case for using American-made, clean-burning alternative fuels like autogas and natural gas.

To make the way for a true clean energy future with PEVs, America would need to overhaul its energy grids and greatly expand renewable energy use. The disparity between EVs’ actual contribution to lowering emissions and EV proponents’ dream of what it could be does not mean we’re stuck with gasoline in 2011– autogas is right here, right now.
