Archive for fuel consumption

As gasoline prices continue to increase further the interest in alternate fuel vehicles. This summer looks set to be the most expensive ever in most countries to fill up a traditional gas tank while simultaneously the demand for electric and hybrid vehicles is generally outstripping supply. As I’ve written before one of the consistent arguments against electric vehicles to date has been the lack of range offered by most options currently on the market, at least at the more affordable end of the market. There is very good news however coming from Hyundai Motor Company that could signal a major change to help overcome this not insignificant obstacle. I’m still trying to find official word on just how soon these vehicles might be ready for the commercial market.

To date most electric vehicles have offered a range per charge in the vicinity of 110-130 miles (177-209km ) which doesn’t fare well when compared with a normal gasoline powered sedan. The new Fuel Cell Electric Vehicles (FCEVs) from Hyundai have just completed road tests which provided results of 211 miles (340 km) from a single charge. Still not quite on par with a 2.0 liter sedan powered by gas but almost double where the reluctantly accepted industry norm resides. For commuters it takes an electric vehicle away from the range of inconvenient to being far more practical. You could have a 15 mile each way commute starting with a fully charged car on Monday morning and still have battery power to burn on the way home Friday night. While this doesn’t resolve the issue with long range city to city journeys it does begin to level the playing field. Even a fuel efficient gasoline powered car needs to fill up from time to time with a long highway journey (typically after completing 275-375 miles).

Hyundai are offering two of their prototype 1x35FCEV electric vehicles for test conditions throughout northern Europe this summer as part of a campaign designed to make major inroads in the European market for electric vehicles, seen by automakers as the most responsive to the new technology. A season of public events has been booked to help market the vehicle and show consumers that the forthcoming electric vehicles are not only eco-friendly but also competitive.

Adding range to electric vehicles could make Hyundai a market leader in the field

The Hyundai ix35 FCEV only emits water vapour and offers very comparable stats to a similarly sized vehicle with an internal combustion engine. In addition to the great improvement in vehicle range it offers a maximum speed of 99 mph / 160 km/h and reasonable zero-to-60mph acceleration time of 12.6 seconds.

Final specifications, pricing and release schedule are still to follow but this should provide confidence that the issue of vehicle range for electric cars can and will be addressed.

The automotive industry continues to reinvent itself and as it does so I think we’re going to a continuation of environmental benefits beyond the engine and source of fuel. If you are anywhere near the same vintage as myself think back to the days of your youth and your parents vehicles. In my case it was the early 1970′s and almost everything on the exterior of the car was made of steel, from the bumpers/fenders to the wing view mirrors and the whole body metal was the order of the day. In the subsequent decades car manufacturers have gradually added more and more plastic and plastic compounds to the exterior of the vehicle making cars lighter, quicker to make and easier to repair after accidents. If you’ve ever wondered how much of your own vehicle actually is still made from steel try placing a magnet to any of the panels and see what happens.

The percentage of car body parts made in plastics continues to increase but the environmental cost of plastic is far from ideal. Imagine this however, in the relatively near future much of your automobile’s body and interior could essentially be made from compounds from bananas or pineapples. I’m not kidding.

An intriguing report from scientists in Brazil who are testing new fiber compounds from these and other plants to create a new hybrid of automotive plastics. It’s not just change for change sake either even though of course the production of such compounds would be sustainable, but the new plastics are also testing to be lighter and stronger as well. The findings were presented at the National Meeting and Exposition of the American Chemical Society and really do hold the potential to completely change manufacturing techniques not just in the auto industry but in many processes that use strong plastics. They are collectively known as nano-cellulose fibers and while current equivalents being used typically are made from petroleum or natural gas the nano-cellulose compounds would be completely renewable. The leader of the study Alcides Leão, Ph.D adds:

“The properties of these plastics are incredible. They are light, but very strong — 30 per cent lighter and 3-to-4 times stronger. We believe that a lot of car parts, including dashboards, bumpers, side panels, will be made of nano-sized fruit  fibers in the future. For one thing, they will help reduce the weight of cars and that will improve fuel economy.”

The testing is providing very impressive results in addition to the reduction in weight and gains in strength these reinforced plastics also are proving to be more resistant to damage from spilled gasoline, water and heat. If it all sounds a little like science fiction, it’s not at all as the researchers estimate that this new product could be in the marketplace within the next 2 to 3 years. The study shows that plant fibers with their natural composition of cellulose are perfectly suited to such applications, while we’ve long benefited from the application of the more common compound to make paper and cardboards these smaller fibers have an ideal composition for this use.

The team report that it is using the stems and leaves from pineapples rather than wood to make the ideal source for the creation although other species such as agave, coconut and banana plants also provide excellent solutions. The Palm products are inserted into the equivalent of a pressure cooker and then added chemicals create a mixture that over heating cycles will ultimately resemble a powder. Although the process is expensive it will take one pound of nano-cellulose to generate 100 pounds of the new lightweight plastic. At this point I’m relying on your scientific knowledge being much stronger than mine but it certainly sounds like a fascinating development. Leão also stated that although the initial testing is aimed toward automotive plastics and replacing them, future applications could include replacing certain steel or aluminium vehicle parts as well as numerous medical applications.

EPA ethanol ruling seems counterintuitive

Posted by: Tim | Comments (1)

According to Bloomberg the Environmental Protection Agency are anticipated to approve a ruling that might just be the most backward decision that I’ve read about in years. I’ll get to the ruling in a moment but I want to start with the fine print – exactly what the impact of the decision might be (which questionably won’t be the piece that the media focus upon). Gasoline prices as you’ve noticed have been steadily creeping up for many months now with average prices now at their highest in over two years and industry insiders predicting further increases of up to 15 to 20 percent this year. While commercial vehicles will still drive all the miles that are required the expectation is (was) that fuel consumption might reduce slightly for private use as drivers question the value of extra leisure mileage in their vehicles due to cost. I don’t need to explain it to you but perhaps I should write to the EPA – reduced fuel consumption equates to reduce pollution.

Why then would the EPA support a decision that is expected to stabilize and perhaps even lower the price per gallon throughout the United States?

The rule which the agency may be passing would approve the use of E15 for vehicles that were built after the year 2000. E15 fuel is a synthetic blend consisting of 85 percent gasoline with 15 percent ethanol – automakers view it as the enemy citing the fact that increased ethanol is capable of harming components of a vehicle’s engine. Last year a temporary waiver was granted to ‘Growth Energy’ who had campaigned on behalf of ethanol whilst representing various manufacturers and suppliers within the industry. The waiver allowed the normal blend (10% ethanol) to be increased to E15 for vehicles built from 2007 onwards, that initial decision has been met with opposition from manufacturers revisiting the claims of vehicle damage.

Here is the intriguing part which I don’t think is really being looked at and it doesn’t take the most tenuous mathematical theory to prove it. Most environmentalists would of course applaud the increased use of ethanol (grain alcohol) to help power motor vehicles – it is cleaner and is of course not burning a fossil fuel. Increasing that ratio from the typical 8 to 10 percent nationally to 15 percent would see more ethanol on the market, but the seven percent reduction in petroleum is completely misleading. It’s only a winning theorem if drivers curtail the miles they drive annually. Simply in population terms US demand for fuel will increase each year as more drivers take the road – the only significant downturn in gasoline use in recent years was when fuel charges rapidly spiked a few years ago. Depending on which report you read consumer demand for gasoline fell by as much as 18 percent, a trend that is being followed again over the last six months even though prices have not returned to their previous national high just yet. Currently the US averages is $3.10 cents per gallon which seems to be right around the break even point where consumers notice it being too expensive – if the anticipated increases to a four dollar gallon were to take place this summer you can essentially guarantee a lower demand from consumers. If the E15 ruling goes ahead the rapid increase in ethanol use will change prices at the pump even in some cases it will only see them as stabilise at first. The reason being is that refiners receive a 45 cent tax credit for each gallon of ethanol that they use. That tax credit could then most likely would be used by refiners to offset rising fuel prices and in some locations may see a drop in price. Why would refiners pass on their savings? To secure high demand – which in actuality would be ‘normal demand’ which is far too high in the first place.

Another asterisk that you have to place against ethanol usage is the fact that it will often result in a slight but consistent reduction in fuel economy due to the lower energy density, even if it’s only one or two percent it once again slices away any potential gains environmentally if the subsequent demand for petroleum increases by the same amount.

While nothing would please me more to say that most drivers will change their choice of vehicle and fuel due to environmental matters the fact is that nothing changes driving habits in the US is significantly as more expensive gasoline, if we could eliminate that long-term passionate desire for cheap gas (which would be $2.40 a gallon in 2011) we might just see alternate fuel vehicles really take hold. As the cost of oil recovery, refining, transport and marketing continues to increase as will the pump price – trying to manipulate that only slows our transition to better driving habits and hybrid or electric vehicles. The front end of the EPA decision looks logical but the consequences may be just the opposite of what environmental protection means.
