Green Options

On the heels of the opening of Coskata’s first flex ethanol facility capable of making ethanol from virtually any organic material, GM and Coskata have released a video (below) detailing the Coskata process. Unlike most promotional/informational videos that get dumped on the public, this one is actually rather informative.

Pennsylvania is beautiful this time of year, but I missed most of it since I made the 400+ mile drive mostly in the dark. It took eight hours of dodging speeding semi-trucks and going through many miles of tunnels, but I finally made it to the Westinghouse Plasma Center in Madison, PA. In case you’re asking, yes, the same Westinghouse that makes flat screen televisions (among other nifty tech stuff).

The Coskata semi-commercial flexible ethanol plant, dubbed “Lighthouse”, is located here. This facility is essentially a working scale model of a full size ethanol plant, and the processes and technology here can one day soon be scaled up to produce as much as a 100 million gallons of flex ethanol annually. The important word here is flexible, because unlike other ethanol products, the Coskata process can use just about any carbon matter to produce ethanol. This means the very garbage filling our dumps may one day instead fill our cars.

Editor’s Note: This is a guest post from David Hone, Climate Change Adviser for Shell.

I have been in Sao Paulo this week at Sustentavel 2009, perhaps the premiere Sustainable Development event in Brazil, if not all of South America. At the opening I represented the World Business Council for Sustainable Development and then on the first day of presentations I participated in the main climate change panel session.

What is clear is that there is a passion in Brazil for sustainability – from the huge issues they face in the Amazon region to the road congestion in Sao Paulo. Talking with delegates at Sustentavel, it is also clear that the country faces an interesting future in terms of greenhouse gas emissions.

Running your car on used cooking oil is so 2008. The hottest feedstock for home-grown vehicle fuels is wood chips.

Well, maybe not everyone’s doing it. But at least one resident of Alabama is, and he’s trying to spread the word about his innovation.

Wayne Keith of Springville, Alabama, who’s a cattle rancher and a partner in Renewable Energy Systems LLC, was inspired to develop his Bio-Truck back in 2003, when gas prices reached $2 a gallon. Looking for a better way to fuel his 1984 Ford truck, which he uses extensively on his ranch, he started building a gasifier that produces syngas from the partial combustion of wood.

New York’s Ontario County is exploring the possibility of turning garbage into gas at the county’s landfill.

The county is debating whether to let Casella Waste Systems, which runs the landfill in the town of Seneca, build a $5 million pilot plant there. If the pilot proves successful, a $100 million plant could eventually be built on the site, reports the Rochester Democrat and Chronicle. The idea will be debated at a public hearing tonight.

Currently the landfill takes in about 2,200 tons of trash a day from 33 counties, other states and Canada.

The renewable energy startup Ze-gen, Inc., has put a new spin on an old technology. Before the advent of the electric light bulb, many cities used coal gasification to provide fuel for their street lamps, and as the costs of oil and natural gas soar, many are reconsidering this old method in the hopes of providing cheaper sources of fuel.

If you spent any time as a child in the 80’s, you probably spent a more than a few afternoons longing for your own flying DeLorean, hover-board, and Marty McFly Nikes.

Unfortunately, you still can’t have any of those things (although the Nikes did appear on eBay, briefly, and sold for $1300 US), but maybe you can have something better:  a real, honest-to-goodness Mr. Fusion!

The “Mr. Fusion” reactor mounted to the back of Back to the Future’s famous DeLorean hovercar produced the car’s fuel by extracting chemical energy from common household garbage.  While the 1985 movie version of Mr. Fusion put out enough power to juice the good Doctor Brown’s flux capacitor all the way to the year 2015, the 2008 version will probably only get a few miles down the road.

Under a new research directive at Ames National Laboratory, scientists are honing in on a way to use a process called gasification to create cheap ethanol from almost any carbon source without fermentation. If they’re successful, crops, agricultural waste, lawn clippings, raked leaves, sewage sludge and garbage could all be turned into ethanol using the same efficient process, in the same facility, under one roof.

The Cafe Racer Truck Runs on 100% Recycled Coffee Grounds

A commenter on Ben’s wood-powered truck post pointed us to a similar car hack. The truck above is also powered by a wood gas generator, except this one runs on coffee grounds. The Cafe Racer is a 1975 GMC pickup that essentially burns up used coffee to create a combustible gas. The gas is filtered on its way to the engine and, Viola, a caffeine-powered truck.

Earlier this year, headlines were made on the announcement of biotech start-up Coskata promising to revolutionize the production of ethanol with a process that could use a variety of feedstocks, ranging from wood chips and switchgrass, to old tires, and even directly from municipal waste. Most importantly, it did not rely on corn or other food stocks in order to produce fuel. At the time, Coskata was predicting an aggressive timeline, with a pilot demonstration plant to begin operation in 2009, and a first full-scale plant to be underway by 2011.

Last week Coskata announced the location for their pilot demonstration plant, a facility that will begin producing 40,000 gallons of ethanol per year, starting in 2009. While that is only a tiny drop in the proverbial bucket, it’s another step along the path to having a full-scale plant in operation and producing 50 to 100 million gallons of ethanol per year.

On Friday I spoke with CEO Glenn Farris about his company, Biomass Gas & Electric.

CleanTechnica: What does your company do?

GF: We use biomass (primarily woody biomass), but also forest residues, agricultural waste, and woody crops, to produce renewable energy in an environmentally beneficial gasification process that doesn’t involve combustion, and so is carbon neutral. BG&E currently has three contracts (Georgia Power Company, The City of Tallahassee and Progress Energy of Florida) to provide biomass-generated electricity, pipeline gas, and hydrogen. We have many, many other projects in development both in the U.S. and abroad. In states that have a Renewable Portfolio Standard, we provide tradeable renewable energy certificates. In other states, we sell renewable energy credits to large companies like IBM and Alcoa, who want to reduce their carbon footprint. We believe the future of the company is in the production of methane.
