Alt Fuels

A study funded in part by the U.S. DOE found that ethanol is at least 24% more carbon-intensive than gasoline. It contradicts the conclusions of a 2019 USDA study suggesting ethanol has GHG benefits.

Smog-forming emissions might not be any better with synthetic fuels, according to testing commissioned by a European environmental group.

Hydrogen-fueled internal combustion engines are the focus for a partnership among a range of Japanese makers of two- and four-wheeled vehicles.

GAC Motor joins the ranks of companies considering internal combustion hydrogen engines as part of a future CO2-cutting solution.

Gas stations, tailpipes, and internal combustion engines will soon be ushered out. Could synthetic fuels ever possibly turn the tide?

Mazda's varied vision of the future includes EVs, hybrids, and a Skyactiv-X six—but no diesel for the U.S. We consider why that didn't work out.

Keeping internal combustion alive through synthetic fuels with a lower carbon footprint is not a better solution than batteries, T&E argues.

Toyota sees potential in hydrogen internal-combustion engines as part of a future racing program—perhaps to boost interest in its plans for a hydrogen economy.

Porsche is among the automakers hoping to find a way to keep internal combustion alive as a niche, with a sustainable new twist at the fuel-making level.

Illegal delete kits and tampering with emissions equipment is so common that is creates more noncompliant vehicles than the VW diesel scandal, a new EPA report suggests.

Concern over an ethanol downturn, possibly exaggerated by EVs, has both campaigns—and Congress—pandering to the Corn Belt.

FCA is recalling Jeep Grand Cherokee and Ram 1500 models with the EcoDiesel V-6 for an engine-stalling issue, fixed with a software update.

Until the Jeep Wrangler 4xe plug-in hybrid arrives, the Wrangler EcoDiesel is the high-mileage off-road leader. Is it eco enough?

Mercedes and parent company Daimler AG will pay $1.5 billion in penalties, as it continues to priorities Europe over the U.S. for cleaner EVs.

Through BMW i Ventures, the automaker is putting its brand behind gasoline that might help lower emissions versus fossil-fuel sources.

McLaren is planning to give synthetic fuels another try, although it knows that they won't replace battery-electric technology at this point.

Will the corn ethanol industry survive a year when refiners are holding back and gasoline pump prices drop as low as $1 a gallon?

With the addition of an EcoDiesel V-6 engine achieving an EPA 29 mpg highway, the Jeep Wrangler is no longer a gas-guzzler.

Despite controversies over a formulation that adds to smog issues, a Trump push for more E15 gas has been stymied by state rules and costly station retrofits.

In a process that's a bit like a flow battery, scientists have generated electricity by spraying salt water on a rusty film.
