Green Gasoline Could Power Future Cars and Jets Email Green Gasoline Could Power Future Cars and Jets Virginia, United States [RenewableEnergyWorld.com]
Researchers have made a breakthrough in the development of "green gasoline," a liquid identical to standard gasoline yet created from biomass sources like switchgrass and poplar trees.
Chemical engineer and National Science Foundation (NSF) CAREER awardee George Huber of University of Massachusetts-Amherst (UMass) and his graduate students Torren Carlson and Tushar Vispute have recently announced the first direct conversion of plant cellulose into gasoline components.

Trash Today, Ethanol Tomorrow Email Trash Today, Ethanol Tomorrow
Maryland, United States [RenewableEnergyWorld.com]
University of Maryland research that started with bacteria from the Chesapeake Bay has led to a process that may be able to convert large volumes of all kinds of plant products, from leftover brewer's mash to paper trash, into ethanol and other biofuel alternatives to gasoline.

Biochar Offers Answer for Healthy Soil and Carbon Sequestration Email Deep, rich, black soil is a farmers dream come true. Healthy soil is full of life, with entire communities living just below our feet. Healthy soil can retain and purify water, provide an abundance of food, and even act as way to sequester carbon dioxide. One key to getting there is amending soil with biochar . Biochar is what you get when biomass is heated in the absence of oxygen through a process called pyrolysis. When incorporated into soil, biochar provides the structural habitat needed for a rich community of micro-organisms to take hold. Incorporating biochar into soil can also act as a way to sequester carbon.

Solar Power Around the Clock, Enough for 90% of U.S. Grid Email Ausra: Solar Power Around the Clock, Enough for 90% of U.S. Grid
Nobody can fault Ausra for lack of ambition. The solar power-plant maker has released a peer-reviewed paper claiming that solar-thermal electricity could power 90% of the US grid, with enough left over for plug-in hybrid cars . "The company estimates that such a changeover would eliminate 40 percent of the country's greenhouse gas emissions with a land footprint of 9,600 square miles, about the size of Vermont".

Low-cost Solar Thermal Plants Email Low-cost Solar Thermal Plants at Heart of Algerian-German Research Push
by Jane Burgermeister, European Correspondent
Vienna, Austria [RenewableEnergyWorld.com]
The development of a new generation of large-scale, low-cost solar thermal power plants is the focus of a joint research agreement signed between Algeria and Germany
Researchers will be sharing data and expertise to speed up the market introduction of large-scale solar thermal plants. The plants could supply up to 200 megawatts (MW) of electricity and desalinate water for 50,000 people.
Electricity from solar thermal plants could cost as little as €0.04/kilowatt hour (kWh) [US $0.06/kWh] by 2015 to 2020, Bernhard Milow from the German Aerospace Center (DLR) said. And using solar thermal power to desalinate seawater could cost the same.

Carbon Output Must Near Zero To Avert Danger Email Carbon Output Must Near Zero To Avert Danger, New Studies Say
The task of cutting greenhouse gas emissions enough to avert a dangerous rise in global temperatures may be far more difficult than previous research suggested, say scientists who have just published studies indicating that it would require the world to cease carbon emissions altogether within a matter of decades.

World can 'afford' to solve its environmental woes: OECD Email World can 'afford' to solve its environmental woes: OECD
OSLO (AFP) - The world could solve many of the major environmental problems it faces at an "affordable" price, the OECD said Wednesday, warning that the cost of doing nothing would be far higher.
In a report presented in Oslo , the Organisation for Economic Cooperation and Development suggested a range of measures to address what it said were the greatest global environmental challenges through 2030: climate change , biodiversity loss, water scarcity and the impact on human health of pollution and toxic chemicals.

Sodium Sulfur Batteries to be Used for Energy Storage at MN Windfarm Email Sodium Sulfur Batteries to be Used for Energy Storage at MN Windfarm
Xcel Energy , (NYSE: XEL )in partnership with the University of Minnesota , the National Renewable Energy Laboratory and the Great Plains Institute, will soon begin testing a one-megawatt sodium-sulfur battery storage system to demonstrate its ability to store wind energy and dispatch it to the electricity grid when needed.
Fully charged, the batteries could power 500 homes for six and one-half hours. Xcel Energy will purchase the batteries from NGK Insulators, Ltd. that will be an integral part of the project. The sodium-sulfur battery is commercially available and versions of this technology are already being used in Japan and in a few US applications, but this is the first U.S. application of the battery as a direct wind energy storage device.

An update on international wood pellet markets Email An update on international wood pellet markets
The use of wood pellets as fuel for domestic stoves and boilers and for co-firing in thermal power plants has been an amazing success story over the past 10 years. Recently, the exorbitant speed of growth caused supply problems and a slowdown of markets, but the next boom is waiting, says Christian Rakos.

Work starts on Gulf 'green city' Email Work starts on Gulf 'green city'
Abu Dhabi has started to build what it says is the world's first zero-carbon, zero-waste car-free city. Masdar City will cost $22bn (£11.3bn), take eight years to build and be home to 50,000 people and 1,500 businesses.
The city will be mostly powered by solar energy and residents will move in travel pods running on magnetic tracks.
