Alt Fuels

You can virtually throw a stone these days and hit someone developing a "fuel of the future", but some do appear to show more promise than others. Many options for future transportation have their disadvantages, but Alchemy Research believes there's one option that could solve several of our fuel...

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That future has taken a blow in California, with the news that $27 million in grants for hydrogen filling stations has been revoked by...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...

Hydrogen fuel-cell cars have not progressed as fast as some companies had predicted 10 or 15 years ago. No carmaker sells a fuel-cell vehicle in any kind of volume, but plug-in electric cars are on sale in North America, Europe, and Asia, with tens of thousands sold (and likely more than 100,000...

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...

In terms of renewable energy, you have to give credit to the first person who thought of using excrement as a source of fuel. At the risk of dragging things down to gutter-level, one place you'll find one heck of a lot of excrement is at a zoo. You don't need us to tell you that big animals produce...

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...

Continuing his efforts to reduce U.S. dependence on imported oil, President Barack Obama yesterday proposed expanding tax credits now offered to buyers of plug-in cars to those who buy natural-gas vehicles as well. Given the ugly politics around electric cars and the presidential election season...

General Motors announced today it will offer bi-fuel versions of its 2013 Chevrolet Silverado and GMC Sierra pickup trucks that run either on gasoline or natural gas. The two trucks are the 2500 HD (heavy duty) model, and can be ordered in rear-wheel or four-wheel drive and with a standard or long...

For years, the great and the good of Hollywood have helped encourage people to ditch gas guzzlers by turning up to red-carpet events and driving around Beverly Hills in an eclectic mix of trendy eco-cars. But when those cars are traded in for the latest, greenest model, or perhaps swapped for...

If you choose to run your car on an alternative fuel or electricity, it's not always as easy to find somewhere to refuel or recharge as it might be with a normal gasoline vehicle. Luckily, you have technology on your side in the modern age. So below you'll find the best five ways of locating that...

Ferraris aren't typically known for their green credentials. In fact, they tend to be known for everything but green credentials: High performance, for example. High-revving V-8 and V-12 engines. Being painted very, very red. Not being painted green. Most methods of extracting greater power from...
