OK. I admit it. I am writing this article from a Summit about cow poop. No, this isn’t a joke to get 8-year olds rolling on the floor with laughter. This is serious.
I am reporting from the inaugural National Biomethane Summit, in Sacramento, California, where over 300 attendees including elected officials, government agencies, farmers, ranchers, landfill owners, facility owners and operators, technology leaders, researchers, regional planners, and carbon trading experts.
Biomethane is renewable natural gas because it is from biological sources. In some areas, biomethane is called renewable gas. Biomethane is a low carbon fuel – CH4. John Boesel, President of CALSTART, calls biomethane “Our lowest carbon fuel.” Just like the fossil fuel version of natural gas, biomethane can be converted into electricity or fuel.
Making money from meadow muffins is helping dairy farmers stay in business. Among the Western United Dairymen, 18 projects that capture biomethane from manure are generating 4.425 MW of electricity. Hilarides Dairy also converts enough biomethane into fuel to power two of its heavy-duty and five pick-up trucks. Michael Marsh, CEO of the Western United Dairymen quipped, “This smells like an opportunity.”
Dallas Tonsager, Undersecretary, U.S. Department of Agriculture (USDA), is a former dairyman who sees big economic opportunity in methane from manure. Since 2003, USDA has helped 121 projects with co-funding and/or loan guarantees. These projects have generated 449 GW hours/year of electricity, reducing emissions 384,664 metric tons of CO2e and displacing 8 million gallons of oil.
The 121 projects include WI 24, PA 18, CA 14, NY 14, and VT 7. There are opportunities in every state. USDA is encouraging the growth of biomethane for energy and fuel. This is definitely a “shovel ready” opportunity to create green jobs.
Across the nation, ranchers, farmers, landfill operators, and all that generate agricultural waste, forest residue, and municipal waste can increasingly become energy independent. Through anaerobic digestion much of their biological waste can be converted into biogas which can run electrical generators, turbines, or fuel cells to generate electricity. Biogas can also be converted to cleaner biomethane for cleaner electricity and renewable fuel. These operations can generate their own electricity and fuel their own vehicles. Increasingly, excess electricity and fuel can be sold as added revenue streams.
A growing number of our nation’s buses, refuse trucks, delivery vans, airport and port equipment has been converted from diesel to natural gas. Michael Gallagher, CEO of Westport Innovations, has already sold 20,000 engines for such applications. He estimates that 20 percent of our nation’s diesel vehicles could be running on biomethane produced in the United States.
Nations like Russia and Iran that control the largest reserves of natural gas may not like this trend of making our own natural gas, but if we want energy independence then we need to follow W.C. Field’s advice, “Take the bull by the tail and face the situation.”

I hate to be negative, but according the CIA World Fact Book, Sweden imported one billion cubic meters of natural gas in 2007. The 40 million cubic meters mentioned in this article sounds like a lot on the face of it, but it’s just 4% of Sweden’s annual consumption. I don’t think the Russians need to worry just yet.
But still — it’s certainly a good idea to make fuel from waste. Every bit helps.

CH4 is CH4. The source is irrelevant, but it is interesting that much of the “global warming hazard” CH4 comes from cattle burps and farts.
Can anyone explain why this fact is ignored by the “Global Warming” alarmists?

Hi ChuckL – don’t know that they ignore it but it is a bit difficult to do anything about – except go vegetarian which I am not even a little interested in.
Actually the problem is being worked on by many parties – changing diets etc.
Like John said – Russia could care less – it is a small amount to them and will only make their supply last longer.

“…He estimates that 20 percent of our nation’s diesel vehicles could be running on biomethane produced in the United States….”
If that’s true, this idea would reduce GHG emissions a few orders of magnitude more than running all of our diesel vehicles on soy or canola biodiesel.

You know, even with this economy, poop and fumes help all of the time! you just need to know what you do with it. Obama can’t stop us from using poop to power our house, can he??
*ChuckL – It is true that a large part of greenhouse gas climate forcing is due to methane, as methane is 300 times more climate forcing as CO2, and CFC’s are 1000 times more. Methane also has a much shorter half life in the atmosphere than CO2, which means that capturing these methane emissions and using them for fuel is not only good for national security, because it is renewable, but also helps reduce the effects of man-made global warming much faster than reducing CO2 emissions in the same amounts.
Cows are not the only source of methane emissions, as rice paddies, landfills, and mining operations also account for substantial methane emissions. It is the combined effects of these emissions that have half the climate forcing power of the CO2 in the atmosphere.
CH4 captured from these sources, “renewable gas” or “biomethane”, must be converted into energy-grade gas before it can be used in the grid. The fossil-fuel methane we call “natural gas” is more carbon-rich than the methane being discussed in the climate debate and that is produced by cows landfills, etc.
*I think the wonderful thing about this is that it can be done on an individual, local, level. This isn’t about making a ton of energy for export. It’s about making your own energy, with readily available resources, which does not require massive change in the current infrastructure to be usable, which is not only fiscally feasible, but even profitable, for the individuals who invest in it. A better solution than FRACKING, for sure.
