GreenFuel Technologies on Wednesday said that it has completed a round of funding to ramp up its algae-farming projects.

The company landed $13.9 million, which was led by Access Private Equity, Draper Fisher Jurvetson, and Polaris Venture Partners.

A portion of the money will retire debt the company borrowed following a corporate shakeup last year that put Bob Metcalfe in as interim-CEO. The remaining $7.6 million in new capital, which completes its series B round, will go to scale up technology projects.

In a statement, Metcalfe said the company will announce a new CEO, a C round of … Read more

It's not uncommon on California roadways to spot diesel cars with bumper stickers that boast of biofuels in the engine, using slogans such as "Fuel for the revolution."

"This is the largest underground movement in the United States since the Civil War and the underground railroad," said Michael Wittman, an environmental activist and biodiesel user in Los Angeles.

But many drivers who began using biofuels to reduce their carbon emissions and save money fear that little-known government regulations are nipping the adoption of homegrown, "green" fuels in the bud.

In California, it's … Read more

NEW YORK--"Henry Ford had it right all along," E-Fuel founder and CEO Thomas Quinn declared, referring to the fact that many original Model T Ford automobiles ran on the ethanol, not gasoline. But that was before the era of Prohibition, which banned production of the biofuel along with other forms of alcohol.

Now, he hopes ethanol can have a real revival.

In a press event at Revel, a Meatpacking District restaurant that features a greenhouse-like roof and trees growing inside, Quinn and his fellow executives unveiled the EFuel100 MicroFueler. It looks like a cross between a gas … Read more

MTI MicroFuel Cells is hoping to use its portable fuel cells in digital cameras.

The company, a subsidiary of Mechanical Technology, announced Wednesday that it is already working with a Japanese optics manufacturer to adapt its integrated Mobion fuel cell technology for digital cameras.

Fuel cells are being explored as potential power sources for everything from data centers to SUVs. Over the years, MTI Micro has designed products for the industrial and military markets, but as of late, the company has been making a big push on the consumer electronics side, with the hope of replacing lithium ion batteries with … Read more

The United States can slash its use of petroleum dramatically by 2035 by adding a heavy dose of hybrids to the market, according to a study from the Massachusetts Institute of Technology.

To return U.S. fuel use to pre-2000 levels, however, carmakers would have to improve efficiency and consumers would have to learn to love hybrids, trading features like increased speed and size for higher fuel efficiency.

"There's all this fascination with vehicle technology--more hybrids, more diesels, and so on," said study author Anup Bandivadekar, an analyst at the International Council on Clean Transportation, in a … Read more

Granted it's still in prototype stage, but Sony's latest micro-sized hybrid fuel cell nevertheless offers a sneak peek at what to expect of batteries in mobile devices in coming years.

The tiny fuel cell measures roughly 2 x 1.2 inches, thanks to its combination of a lithium polymer battery, fuel cell, and control circuit, with methanol as the fuel, according to Tech-On Nikkei. A pump regulates the fuel supply to cater to the device's power needs.

Sony says one-third of an ounce of methanol can provide almost 14 hours of 1seg TV viewing on mobile phones, … Read more

When it comes to next-generation biofuels, it's a competition for both technology and capital.

Range Fuels expanded its previously announced series B funding from $100 million to $166 million, according to reports. Private Equity Hub on Monday cited a regulatory filing, saying Morgan Stanley Capital Group joined the round. VentureBeat reported the expansion last week.

The money will be used to build the first phase of its ethanol plant in Soperton, Ga., which will use forestry waste as a feedstock. The plan is to complete a 20 million gallon-per-year plant next year that uses a gasification process.

There's … Read more

Attention mountain climbers, hikers, backcountry skiiers, and city dwellers with no sense of direction: new technology could make your handheld GPS device more energy-efficient and let its battery last longer.

Fuel cell manufacturer MTI Micro announced on Friday that it has created a prototype for an embedded fuel cell for handheld GPS devices.

The company said it will provide three times as much power as a set of four AA batteries would, keeping the GPS gadget in question powered for up to 60 hours of continuous use. That's crucial for many users of handheld GPS devices, who are often … Read more

Can the lowly algae ease a growing food-versus-fuel debate?

A growing number of start-ups are betting against the dominant biofuel crops--corn and soy--and looking to sidestep the backlash against biofuels, which are being blamed in part for higher food prices and deforestation around the world.

Melbourne, Fla.-based PetroAlgae says that it hopes to test a commercial system as early as next year.

The company licensed strains of freshwater algae bred by Arizona State University and is developing the bioreactors and harvesting methods to grow the algae at large scale, said Fred Tennant, PetroAlgae's vice president of business development. … Read more
