First Flex-Fuel Plug-in Hybrid Electric Vehicle

As part of a push by the US Department of Energy (DOE) to make plug-in hybrid electric vehicles (PHEVs) cost competitive with other cars by 2014, Ford has delivered a plug-in hybrid electric flex-fuel Escape to the DOE to join its test fleet of other PHEVs currently undergoing research and testing.

The vehicle is equipped with a 10 kilowatt lithium ion battery that can take it up to 30 miles at speeds under 40 mph before needing to fire up its fuel-fed hybrid-electric engine. After that, the hybrid-electric engine kicks in and can deliver a fuel economy of 88 mpg in the city and 50 mpg on the highway when using E85 (85% ethanol/15% gasoline blend).

CleanTech Biofuels is serious about turning garbage into fuel and sincerely hopes you’ll ignore the fact that your car’s fuel tank could be carrying what’s left of little Timmy’s soiled nappies.

The company has announced that it’s investigating suitable sites for commercial garbage-to-ethanol facilities — leading baby-owners everywhere to rejoice that they may never again have to feel guilty about throwing out enough diapers each day to put the elephant in this commercial to shame (and can I just be the first to say “WTF?” to that commercial).

In the June 2008 issue of the journal Nature Reviews Genetics, internationally renowned biofuels researcher Mariam Sticklen proposes that future production of cellulosic biofuels will be made infinitely more efficient and affordable through genetic modification of cellulosic feedstocks such as cereal grains and perennial grasses. Citing the impossibility of fueling the world on starch-based ethanol, such as that from corn, Sticklen argues that cellulosic biofuels are the only viable option for future commercial production.

Biofuels are increasingly lumped into a single category of environmentally apocalyptic dead-end solutions. As the food vs. fuel debate rages on, it’s no wonder that the general public believes this.

But not all biofuels are created equal, as the chart above illustrates (click the image to see full size). It’s one of the best depictions I’ve seen of how each biofuel feedstock has completely different impacts on overall greenhouse gas emissions, water and pesticide use, and the energy required to produce the fuel.

AutoblogGreen reported today that the cellulosic ethanol company Mascoma has received another $10 million for research and development from Marathon Oil. This comes after GM’s undisclosed equity share in the same company was announced last week, and puts the grand total raised in this round of financing at $100 million. Read the rest of this entry »

General Motors announced today it would be entering into a strategic relationship with Mascoma Corp., a second-generation biofuel company with the technology to produce cellulosic ethanol from non-food sources via a single-step biochemical conversion.

The undisclosed equity share aims to contribute to joint research and development along with technology exchange, plant siting, and rapid commercialization of cellulosic ethanol technology and infrastructure. This is GM’s second investment in a cellulosic ethanol company, after announcing partnership with Coskata back in January. Read the rest of this entry »

Researchers at Michigan State are trying to get corn-stover to digest itself after harvest. Doing so would mitigate the costly pretreatment steps needed for the production of cellulosic ethanol from the non-edible parts of the corn plant.

MSU’s scientists are adding genetic material to the corn’s genome, genes that would normally be responsible for the digestive enzymes produced by fungi and the microbes in cow rumens. The newly transgenic plants store these enzymes in vacuoles in the leaves and stalk in a way that doesn’t affect the plant while it’s alive.

Range Fuels Inc. announced yesterday it has secured over $100 million in Series B funding, an investment that could make it the first company to seriously commercialize cellulosic ethanol. The first phase of construction will produce 20 million gallons of mixed alcohols per year by 2009, and has the potential to expand to up to 120 million gallons.

Range Fuels says their facility will break down any type of plant material (eg agricultural waste or wood chips) by a two-step thermochemical process. This differs from competing methods of producing cellulosic ethanol, which involve breakdown of plant material with heat and/or acid, and treating it with costly ($0.50/gallon) enzymes.

In January, USDA researchers completed a five-year evaluation of another biofuel feedstock with the potential to make a serious dent in US petroleum usage. In the largest study to date, switchgrass has been shown to produce 540% more energy than was used to grow, harvest, and process it into cellulosic ethanol, while reducing greenhouse-gas (GHG) emissions by 94% when compared to gasoline.

USDA geneticist Ken Vogel commented that the study demonstrates switchgrass’s potential to be a major renewable biofuel that reduces GHGs and could “potentially displace 30 percent of current U.S. petroleum consumption.” Read the rest of this entry »

The first commercial cellulosic ethanol facility to convert waste wood materials into a renewable fuel went online last month near Upton, Wyoming. After 6 years of development, KL Process Design Group, in conjunction with the South Dakota School of Mines and Technology, has produced a proprietary enzymatic method to break down wood and waste materials, such as cardboard and paper:

KL’s cellulosic ethanol plant is converting waste wood into a renewable fuel. “It is now possible to economically convert discarded wood into a clean burning, sustainable alternate motor fuel” said Randy Kramer, president of KL Process Design Group, a design firm that has been working in corn ethanol. “We’re proud of what this small company has accomplished, and believe that our design will be a cornerstone from which we can build our country’s renewable fuel infrastructure providing a better source of motor fuel, starting today.”

The press release makes no mention of production volumes or plans for expansion (I’m currently contacting KL about this), but the company could be the first to capitalize on the massive potential of cellulosic ethanol, namely, making fuel from waste products (see earlier post).
