BIOFUEL CROPS DOUBLE AS GREENHOUSE-GAS REDUCERS
Jan Suszkiw
ARS News Service, June 8, 2007
Corn and soybeans may be the current "go-to" crops for producing ethanol
and biodiesel, respectively. But two other crops—switchgrass and hybrid
poplar—could steal the show in the future when it comes to curbing greenhouse
gases. A recent study conducted by a scientist at the ARS revealed that bioenergy
crops offset their greenhouse-gas contributions in three key ways: by removing
carbon dioxide from the air and storing it in crop roots and soil as organic
carbon; by producing coproducts like protein for animal feed, which saves on
energy to make feed by other means; and by displacement, whereby replacing a
fossil fuel with a biobased one "recycles" rather than adds more carbon
dioxide to the atmosphere.

BIOFUELS: BEYOND CORN
Emily Singer
Technology Review, June 21, 2007
Most ethanol in the United States is derived from corn kernels; hence,
it consumes a valuable food and agricultural product. In addition, growing
corn is itself an energy-intensive process. In an attempt to find cheaper
and more efficient routes to biofuels, researchers are turning to genomics.
Scientists at the Department of Energy (DOE) have just selected the button
mushroom as one of their latest picks for DNA sequencing, hoping to co-opt
fungi's plant-degrading power to produce ethanol more cheaply. Efforts
are also planned to sequence the genomes of the eucalyptus tree and foxtail
millet, a grass closely related to switchgrass.

BUILDING BETTER BIOFUELS
Neil Savage
Technology Review, June 6, 2007
Some biotech startup companies are positioning themselves to take advantage
of an anticipated booming market for biofuels. One such company,
LS9, of San Carlos, CA, is using the relatively new field of synthetic
biology to engineer bacteria that can make hydrocarbons for gasoline,
diesel, and jet fuel. Hydrocarbon fuels are better suited than ethanol
to existing delivery infrastructure and engines, and their manufacture
would require less energy.

CUTTING GREENHOUSE GASES: BIOFUELS THAT DON'T INVOLVE FOOD CROPS
OR MICROBIAL FERMENTATION
Science Daily, July 2, 2007
California researchers plan to make biofuels in a novel way that doesn't
involve food crops or microbial fermentation. A new research effort involving
three University of California campuses and West Biofuels LLC, will develop
a prototype research reactor that will use steam, sand and catalysts
to efficiently convert forest, urban, and agricultural "cellulosic" wastes
that would otherwise go to landfills into alcohol that can be used as
a gasoline additive.

A DIFFERENT KIND OF POWER PLANT
Sam Hopkins
Energy and Capital, June 14, 2007
Alga Technologies (Algatech), based here at Ketura, in the southern Israeli
desert, mass produces algae for cosmetics, nutritional supplements, and
now for energy conversion and production. Algatech's feedstock spends
most of its growth cycle in petri dishes, before moving along to a massive
system of pumps and tubes sitting in the desert sun. This region,
the Arava Valley of the Negev Desert, has the highest solar radiation
levels anywhere in the world -- between ten and 14 hours a day of direct
sunlight hit these plastic tubes and sleeves.

FROM LEFTOVERS TO ENERGY
Emily Singer
Technology Review, June 18, 2007
A University of California-Davis bioengineer has developed microbes that
convert food scraps into energy--mostly methane and hydrogen--that
can be burned to generate electricity or compressed into liquid to power
specialized vehicles.

NEW TECHNOLOGY COULD LEAD TO MORE ENERGY-EFFICIENT ETHANOL PRODUCTION
Marcia Wood
ARS News Service, June 26, 2007
Chemical engineers at the ARS Western Regional Research Center in Albany,
Calif., think it may be possible to cut energy costs by using a series
of specially designed permeable plastic sheets, or membranes, to produce
ethanol from fermented broths of corn, or straw and other kinds of biomass
feedstocks. The technology will help to address the serious concern
regarding the energy efficiency of bioethanol production.

A NEW TREND: FOREST INDUSTRY INCREASES BIOMASS-BASED COGENERATION
Energy & Enviro Finland, June 15, 2007
Increased utilization of biomass in combined heat and power production
at the mills - a trend that started in the Nordic countries and continued
throughout Europe - is now picking up pace in North America and also
globally. The trend involves procurement of external biomass and in some
cases also wastes for additional energy production.

RUNNING CARS ON HYDROGEN MADE FROM STARCH
Kevin Bullis
Technology Review, May 25, 2007
Researchers have developed a way to convert starch, available from numerous
sources including corn and potatoes, into hydrogen gas at low temperatures
and pressures. This enzymatic method produces three times more
hydrogen than an older enzymatic method does, suggesting that it might
be practical to use such enzymes to produce hydrogen for fuel-cell vehicles.

Biopact, June 13, 2007
Researchers from Sandia National Laboratories are looking at the biology
of organisms, known as extremophiles, living in earth’s extreme
environments to help solve the problem of breaking down lignocellulosic
biomass efficiently to convert it into biofuels - the key to a new transportation
economy based on abundant renewable, green fuels.
