While ethanol in gasoline remains a point of contention among automakers, ethanol producers, and the Congressman who love them, renewable diesel fuel seems to be moving quietly forward. Late last month, the U.S. Environmental Protection Agency certified an ultra-low-sulfur diesel blend containing...

Internal-combustion engines typically convert only one-third of the energy stored in gasoline or diesel fuel into usable power. The rest is wasted as heat, noise, or even goes unburnt. So the question for designers of range-extended electric vehicles becomes: How can onboard liquid fuel most...

Russia. Onion domes, remnants of Communism, enormous natural-gas reserves, and a fierce love of Vodka. These elements have now somehow combined to convince Mikhail Prokhorov--reportedly Russia's wealthiest man, new owner of the New Jersey Nets basketball team, newly-minted publisher of the New...

Yesterday, the Environmental Protection Agency approved raising the proportion of ethanol in pump gasoline from 10 percent (E10) to as much as 15 percent (E15). It would be the first increase in ethanol percentage since 1978, when the 10-percent blend was approved. Roughly 70 percent of U.S...

Despite the hype and the near-ubiquity of the Toyota Prius (pictured), most Americans remain leery of buying alternative-fuel vehicles. That’s probably because they don’t have the basic knowledge to understand it, according to a new survey conducted by Harris Interactive. The survey...

E-Fuel is one of 70 companies chosen by VentureBeat to launch at the DEMO Fall 2010 event taking place this week in Silicon Valley. After our selection, the companies pay a fee to present. Our coverage of them remains objective. In the renewable energy sector, customers face a variety of options...

A couple of weeks back, I received an invite to visit Argonne National Laboratory in suburban Chicago. The lab spends a fair amount of time on transportation research--up to 10 percent of what the lab does revolves around transportation--as it looks towards the future of fuels used to power the...

Range Fuels, one of the more successful biofuel startups backed by Khosla Ventures, announced today that it has opened up its first commercial plant to make cellulosic methanol out of non-food feedstocks. Located in Georgia, the facility is expected to pump out 20 million gallons of ethanol and...

There seems to be no end to the number of organic materials that can be converted into usable biofuel to power a car. We’ve seen fuel derived from garbage before, a race car that ran on chocolate, and even a Volkswagen Beetle running on fuel generated from human waste, and now we have news of a...

Most of the focus on new green cars--like the 2011 Nissan Leaf, the 2011 Chevrolet Volt, and a slew of new and existing hybrids--has been on how consumers will adapt to them. But in fact, a portion of early years' production of any of those cars is likely to go into car fleets maintained by state...

The development and launch of the R35 Nissan GT-R was an epic achievement for the Japanese automaker. After all, Nissan was able design and engineer a sports car capable of outperforming exotic supercars with pricetags twice as high or more, as well as make it seat four adults in relative comfort...

Our article last week on Ford's doubling of its flex-fuel models included a mention that diesel models of the new 2011 Ford Super Duty pickup trucks will run on either pure diesel fuel or a mix of up to 20 percent biodiesel, known as B20. Reader Suzanne Johnson responded with the following...

It must be something in the water. Yesterday, we learned that every 2011 Buick Regal will offer flex-fuel capability as standard. Now it's Ford's turn; the company announced today that it will have doubled the number of flex-fuel models it builds by the end of the year, fulfilling a 2006 pledge...

Almost a year ago, we called Bentley's much-touted biofuels strategy "bogus," in an alliterative headline to a piece that was much forwarded around the green-car world. Now we've had a chat with the very reasonable and polite David Reuter, Bentley's head of PR and communications. We still think...

Who knew? Turns out even cartoon classic Betty Boop uses alternative fuels to power her roadster. In "Musical Mountaineers," a 1939 animated short (it totals 6:43), she runs out of gas while driving through hillbilly country, complete with misspelled signs warning of family feuds. Her first...

Your car already runs on (some) ethanol, although you may not know it. Much of the gas sold in the U.S. is now actually a blend: 90 percent gasoline, 10 percent ethanol. It's known as E10, for the percentage of the total derived from the corn-based biofuel. Since 1978, new cars have been able to...

If you watch TV or read the papers, you'll see lots of coverage of people who are pretty unhappy with one facet or another of the U.S. government. This post is about something government seems to do relatively well: pre-commercial research and development. Here at GreenCarReports.com, we usually...
