Char-crossed fuel

Posted on April 1, 2010, in Ag Innovation News

The challenge with biochar is holding it all together. The fine, black soot-like material is a byproduct of biomass gasification. Biochar could be used as a coal substitute if it could be compacted into granules or pellets for easy handling. AURI is working with the Chippewa Valley Ethanol Company (CVEC) in Benson to solve this […]

Gas to fertilizer

Posted on January 1, 2009, in Ag Innovation News

Roseau, Minn. – Gasifiers can turn crop waste into electricity, but can they turn waste into fertilizer? A project in Minnesota’s northland will find out. The City of Roseau is sponsoring a demonstration project to gasify biomass, creating syngas. Hydrogen from the syngas will be precipitated through a catalyst to produce ammonia, which could be […]

Cob Collection Technology Tested

Posted on January 1, 2009, in Ag Innovation News

Benson, Minn. – Specially-equipped combines chomped through several thousand acres of corn this fall — collecting cobs as well as grain. The Chippewa Valley Ethanol Company in Benson collected cobs from its producer-shareholders to gasify and power its 47 million gallon-per-year ethanol plant. CVEC currently gasifies wood chips for power. General Manager Bill Lee says […]

Screen Savers

Cottonwood, Minn. — Jon Mohn is working on a new “screen-saver” program. He has a warehouse full of grass-seed chaff and screenings — material he once threw away. Now he’s hoping to convert this biomass into pellets. The southwest Minnesota entrepreneur and his wife Melissa grow, harvest and process native grass and wildflower seeds. Their […]

Green gas grass

Posted on October 1, 2008, in Ag Innovation News

Cecil Massie wants to skip the cow. Cow manure is getting notice as a methane source for generating electricity. But Massie, a chemical engineer, is looking ahead at making methane from haylage — “to green chop the grasses, ensile them in bunker silos and use that as feedstock in an anaerobic digester.” “It’s analogous to […]

Power Renewal

Posted on April 1, 2008, in Ag Innovation News

Priam, Minn. — A Minnesota cooperative has a new “power point.” Minnesota Valley Alfalfa Producers started plans to generate electricity from alfalfa stems 14 years ago. But after investing six years of effort and millions of dollars, the farmer-owned cooperative was forced to pull the plug on the project when its partners dropped out. Despite […]

The year of innovation

Posted on January 1, 2008, in Ag Innovation News

A 3M chemist made a sub-par batch of glue that wouldn’t bond properly; another worker used it to stick bookmarks in his hymnal. The post-it note was born. It’s a legendary story that brought world fame to 3M — a small sandpaper company that has grown to $23 billion in annual sales worldwide. Companies have […]

Biomass bridge

Posted on January 1, 2008, in Ag Innovation News

Benson, Minn. — A Minnesota ethanol company is building a biomass bridge to an energy self-sufficient future. Chippewa Valley Ethanol Company will gasify wood chips, corn cobs and other biomass to run its plant. The system will go on line early 2008, replacing about 20 percent of the company’s natural gas consumption. Eventually, biomass gasification […]

Waste to watts

Posted on October 1, 2007, in Ag Innovation News

Williams, Minn. –A grassroots power movement is taking hold in northwest Minnesota. Northern Excellence Seed, LLC, plans to gasify grass-seed chaff and straw to make electricity. The Lake of the Woods County business is one of the first companies in Minnesota to generate on-site power from biomass. And it may be the only factory in […]

Gasification groundwork

Posted on October 1, 2007, in Ag Innovation News

Minnesota’s got gas! The state is becoming a leader in the development of small-scale biomass gasification systems, which produce synthetic natural gas. “There’s a considerable amount of buzz about biomass gasification in Minnesota,” says AURI project manager Michael Sparby. Several gasifiers are now being built around the state and more are in the works. The […]
