From our colleague Edna Vassilovski:

July 15, 2010: WIPO published over a dozen patent applications relating to biofuels. DuPont, Novozymes, BP Biofuels UK, Xyleco and Borregaard Industries each had one or more PCT applications publish as follows:

1. DuPont.

Seven PCT applications published relating to pretreatment of biomass for second generation biofuels. The majority of the applications are directed to organic solvent pretreatment processes in which lignin is extracted and enzymatic saccharification is enhanced.

WO2010080464 discloses pretreating biomass in the presence of an organic solvent solution under alkaline conditions in the presence of ammonia and optionally an additional nucleophile to fragment and extract lignin without loss of hemicellulose.

WO2010080462 discloses pretreating biomass in the presence of organic solvent under alkaline conditions in the presence of elemental sulfur and optionally one or more alkylamine and/or one or more additional nucleophiles to fragment and extract lignin.

WO2010080461 discloses pretreating biomass using an organic solvent under alkaline conditions in the presence of one or more sulfide (hydrosulfide) salt and optionally one or more additional nucleophile to fragment and extract lignin.

WO2010080460 discloses pretreating biomass using an organic solvent solution under alkaline conditions in the presence of one or more organo-mercaptan such as thioglycolate and optionally one or more additional nucleophile to fragment and extract lignin.

WO2010080434 discloses pretreating biomass using an organic solvent solution under alkaline conditions in the presence of one or more alkylamine and optionally one or more additional nucleophiles to fragment and extract lignin. According to the specifications of each of the above applications, the disclosed processes surprisingly result in significantly improved lignin fragmentation and extraction and high carbohydrate retention.

WO2010080436 discloses pretreating biomass through simultaneous oxidative degradation and selective extraction of lignin using a solvent solution comprising water in combination with at least one Mn(III) salt.

WO2010080489 discloses pretreating biomass under conditions of high solids and low ammonia concentration and contacting the biomass with a gas comprising about 0.1 to about 20 percent by volume ozone.Continue Reading THIS WEEK IN BIOFUELS, A (PCT) PATENT PERSPECTIVE

On June 30, 2010, the U.S. Department of Energy ("DOE") launched its Technology Commercialization Portal (the "Portal").  The Portal is an online resource that provides a mechanism for investors, entrepreneurs and companies to identify new technologies coming out of DOE laboratories and other participating research institutions.  Relevant technologies include:

  • Advanced Materials
  • Biomass and Biofuels
  • Building Energy Efficiency
  • Electricity Transmission and

…

The DOE announced today that it will provide up to $11 million over three years for improving the conversion via pyrolysis of non-food biomass to biofuels, that can use the existing fueling infrastructure. (Pyrolosis is the process that decomposes biomass using heat without oxygen to produce bio-oil.)

 

Successful applications for projects will (among…

The Washington State Department of Commerce (formerly the Department of Community, Trade and Economic Development or CTED) has announced that it is attempting to revise Washington’s comprehensive energy plan (the “State Energy Strategy”). 

The State Energy Strategy was last revised in 2003, and it does not serve current energy realities and forecasts. Therefore, the Washington State Legislature has tasked the Department of Commerce with updating the State Energy Strategy while taking account the following three goals and nine principles:Continue Reading Washington Revising its State Energy Strategy

Several deadlines relating to the implementation of RFS2 are rapidly approaching and should be strictly followed by renewable fuel producers to avoid loss of the value of RINs under the new system. Producers who miss the registration deadline of July 1, 2010 will be unable to generate RINs until they have completed the registration …

This year’s International BIOMASS Conference and Expo will be held in Minneapolis, Minnesota on May 4-6.  The 6 program tracks will provide specified topic panels and discussions on Crop Residues, Dedicated Energy Crops, Forest and Wood Processing Residues, Livestock and Poultry Wastes, MSW and Urban Wastes as well as Food Processing Residues.

My colleague Graham Noyes and Clayton McMartin of Clean Fuels Clearinghouse recently published a white paper on the massive and staggeringly complex revision of the federal Advanced Fuel Standard (RFS) issued by the U.S. Environmental Protection Agency on February 3, 2010. Graham and Clayton describe how this second generation renewable fuel initiative (RFS2) will bring…

President Obama met today with a bipartisan group of governors from around the country and announced a series of steps the administration is taking to boost biofuels production in the United States.  The President’s Biofuels Interagency Working Group released a report spelling out ways to promote the development of the biofuels industry in the United States…
