The House transportation bill includes provisions benefiting natural-gas vehicles.

The EPA wants to reduce ethanol requirements under the Renewable Fuel Standard.

Changes to the tax code could make LNG more attractive to truckers.

It sounds like an intriguing idea: Make diesel fuel from air rather than fossil-fuel petroleum. Better yet, make it from carbon dioxide--the greenhouse gas whose concentration in the atmosphere has risen precipitously since the dawn of the Industrial Age. Diesel fuel, after all, is a hydrocarbon...

Heading into another U.S. presidential election year, getting more biofuels into the U.S. gasoline supply continues to pose both political and logistical hurdles. But researchers, regulators, and entrepeneurs increasingly see promise in synthetic diesel created from a variety of non-fossil fuel...

Congress has taken an important step to advance cleaner transport with the introduction of new, fairer taxation for natural gas. The 'LNG Excise Tax Equalization Act of 2013' is designed to equalize the discrepancy between taxation of diesel and liquefied natural gas (LNG). ALSO SEE: Tesla Model 3...

A bipartisan group of 36 Senators wants the EPA to require more biodiesel to be mixed into the fuel supply.

Ethanol is a beleaguered fuel these days, with national availability E85 nowhere in sight, rollout of E15 seemingly stalled, and concerns over its full carbon footprint hotly debated. Most drivers pumping gas pay little attention to its ethanol content, which in several states may now be at 10...

Only seven states require ethanol to be blended with gasoline.

Steelmaker ArcelorMittal plans to install equipment that converts carbon monoxide into ethanol.

United Airlines will use biofuel on certain flights in California.

Neste sends a car across the U.S. with just one tank of its renewable diesel.

Three years ago, Volkswagen announced that it was testing two different types of renewable diesel fuel in a pair of its TDI diesel-engined cars sold in the U.S. Now, the company says it has finished its testing, and the results are in. The renewable fuel gave the same performance as conventional...

Among owners and advocates of zero-emission vehicles, few topics generate as much back-and-forth debate (to put it politely) as those cars powered by hydrogen fuel cells. Discussions of wells-to-wheels carbon footprint, the presently nonexistent hydrogen fueling infrastructure, and their purported...

Ethanol use doesn't automatically limit gasoline consumption.

The Chevrolet Impala bi-fuel natural-gas model was delayed over a year, but GM won't say why.

The addition of ethanol to gasoline has now been a political hot potato in the U.S. for more than a decade. Joined by cosponsors from both sides of the aisle, U.S. Representative Bob Goodlatte [R-VA] introduced two bills in February that together would eliminate the Renewable Fuels Act passed in...

Artificial photosynthesis involves breaking down CO2 and water molecules, and recombining them into fuel.

The EPA wants to cut ethanol levels originally mandated by the 2007 Renewable Fuels Standard.

New research suggests claims of biofuels' carbon neutrality are oversimplified.
