When anything is referred to as "not dead yet," it's usually dead--or very close. But despite the headline reference to a legendary Monty Python skit (NSFW), a recent post from Pike Research makes the case that hydrogen fuel-cell vehicles likely have at least a limited role to play in future...

By the end of this year, Honda says it will have more than 200 dealers certified to sell the 2012 Honda Civic Natural Gas across the U.S. Much cheaper than regular gasoline and cleaner-burning, many states offer incentives to encourage drivers to make the switch to natural gas. But there’s...

You felt the earth shake a week ago today when the EPA formally approved the sale of E15 gasoline, right? Oh, you didn't? Not surprising, really. No gas station in the U.S. sells E15 today, and it looks like it may be a while before any given driver sees the stuff showing up as one of several...

By 2015, Germany is expected to have 5,000 hydrogen fuel cell vehicles roaming the streets. That doesn't sound like a great number, particularly when battery-electric cars like the Nissan Leaf are already selling in far greater numbers. But it still presents a problem, as that number relies on a...

A government-funded laboratory that helped pioneer the battery technology behind many electric vehicles, including the Chevy Volt, has recently begun to focus on developing technologies to improve natural gas-powered vehicles, in anticipation of government and industry soon seeking to bring...

Even more so than with electric cars, the future of hydrogen vehicles depends on a network of filling stations to allow people to go about their journeys as normal. That future has taken a blow in California, with the news that $27 million in grants for hydrogen filling stations has been revoked by...

Politics is never pretty, and the politics of alternative fuels seem even less so. Today, The Detroit News reports that the U.S. military's program to reduce its reliance on oil by using ethanol and other non-petroleum fuels could be de-funded in the military authorization bill that's now working...

The Department of Energy has hit out at the recent Coordinating Research Council study into damage caused by using E15 gasoline. In its rebuttal, the DoE points out several flaws in the CRC's study, and says the Council failed to establish a proper control group to determine the statistical...

A new study released today by the Coordinating Research Council says that E15 gasoline, which contains 15 percent ethanol, could damage the engines of certain high-volume car and truck models. The two-year study was conducted on eight different engines from the 2001 through 2009 model years, with a...

A team of researchers at Brookhaven National Laboratory in Upton, New York, has opened the door to a future of clean, cheap hydrogen fuel by ditching a popular platinum catalyst in favor of one based on two low cost alternatives, nickel and molybdenum. Until now, the manufacture of hydrogen gas has...

Ethanol has been problematic for several years now. Promoted as a way for the U.S. to grow its own vehicle fuel, the alcohol was so popular several years ago that Congress passed a Federal Renewable Fuels Standard as part of the 2007 Energy Independence and Security Act. Now Hart Energy has issued...

NASA has developed a system that captures carbon dioxide and helps to prevent pollution from wastewater while creating renewable algae biofuel, fertilizer and possibly animal feed, too. NASA calls its system OMEGA, for Offshore Membrane Enclosures for Growing Algae, self-contained bags of...

If you want a green truck at the moment, your options are limited. By their nature, trucks require large engines, and large engines use a lot of fuel. Until electric and range-extended trucks become a realistic proposition, your best option is either hybrid, or alternative fuels--such as GM's...

Sapphire Energy, a company that creates algae-based fuel, just announced a whopping $144 million in funding. In recent years several startups have emerged to create fuel out of plant material, all hoping to lure people away from gasoline made from crude oil. Solazyme, Algae.tec, and Sapphire Energy...

Progress comes slowly to the world of commercial shipping, but it is coming. Three years ago, we noted that one giant cargo ship emits as much as 50 million cars. Now, shipping lines are starting to experiment with biofuels, which offer several advantages: They contain no sulfur or so-called...

On the face of it, biofuels seem like an ideal short to medium-term solution for reducing our reliance on fossil fuels. After all, they could not only be grown at home--reducing dependence on foreign oil--but growing crops is also a renewable process, and net CO2 emissions are lower than burning...

You'll already be familiar with ethanol-powered cars, but what about methanol? Both are alcohols, but methanol is even simpler than ethanol, containing only one carbon atom. It has less energy content than ethanol, and only half that of gasoline, but it's easier to produce. The fuel is now...

In case you thought we just reported on cars that are green in their energy sources, this 1982 Morgan Plus 8--available on eBay with 1 day left, and first brought to our attention by BringATrailer.com--qualifies both in the figurative and literal senses. Classic roadsters almost always look fine in...

In the not-so distant future, you might find you’ll find an extra choice when you fill up at the gas station, alongside the current choices for Regular or Premium. That’s because the Environmental Protection Agency (EPA) has approved a set of guidelines from the Renewable Fuels...

We missed it last week while we were covering all the new cars at the Geneva Motor Show, but Chrysler has officially stepped forward into the world of natural-gas vehicles. Its Ram truck brand announced that it would offer a bi-fuel version of its 2500 Heavy Duty pickup, to be known as the Ram 2500...
