Subject: US Dairy Farm Manure Begins to Power Homes
The potential annual market for
manure gas is about 150 trillion British thermal units, or
more than 250 million barrels of oil equivalent
http://www.planetark.com/dailynewsstory.cfm/newsid/36548/story.htmUS DAIRY FARM MANURE BEGINS TO POWER HOMESUS: May 26, 2006NEW YORK - Lee Jensen says the manure from his dairy
farm powers almost as many homes as he has cows.The farm is one of three in Wisconsin that has
partnered with New Hampshire-based Environmental Power
Corp. to run machines called methane digesters. The
machine mines methane, or natural gas, from rotting
manure which then powers generators that connect to
local grids, or feed the gas directly into pipelines.The gas from Jensen's 875 cows produces about 775
kilowatts of electricity, enough for about 600 homes,
according to EPC.The machines heat the manure, which also creates useful
leftovers once the gas is removed. Jensen uses some of
the byproduct as pathogen-free bedding for his cows.The machines reduce the size of manure lagoons, making
them less likely to leach into local water supplies.
The process creates seed-free fertilizer to boot. And
there's another benefit. "The odor reduction is
probably the biggest thing that everybody likes,"
Jensen said in a phone interview.The first methane digester was built in 1859, at a
leper colony in India. Use of the machines is a small,
but established practice in Europe.The trend is narrow in the United States, but with high
energy prices and tight electricity generation
capacity, it could catch on. "We're likely to see a
number of cottage industry-type solutions to the energy
problems and although they may only be a drop in the
bucket, every drop helps," said Jason Schenker, an
economist with Wachovia Securities in North Carolina.EPC estimates 1,000 dairy farms across the United
States could be tapped, as well as pig farms, and at
pork and beef production factories. The potential
annual market for manure gas is about 150 trillion
British thermal units, or more than 250 million barrels
of oil equivalent, it says.If it capitalizes on 10 percent of the US market
potential, and if natural gas prices average US$7 per
mmBtu, EPC says it could realize US$120 million in
annual earnings from manure alone.The technology has advantages over solar and wind power
because it doesn't need subsidies. And since cows will
always make waste, there is less risk than drilling for
gas. "We know a well (from the farm) is not going to
come up dry," Albert Morales, EPC executive vice
president, said in an interview.Since methane is a greenhouse gas 21 times stronger
than the main greenhouse gas carbon dioxide, some
farmers have been able to capitalize on selling credits
for burning the gas in voluntary greenhouse gas
markets.Minnesota dairy farmer Dennis Haubenschild, for
instance, sells credits for capturing methane on the
Chicago Climate Exchange. Last year Haubenschild, who
financed his own digester, got about US$10,000 from
CCX. He sold his credits to members of the exchange who
were not able to reduce their emissions of greenhouse
gases under levels to which they had agreed.EPC is in final permitting stages with Joseph Gallo
Farms in California, where it expects two digester
tanks for manure from 3,000 cows will produce 130
billion British thermal units of energy per year, or
enough for 2,200 homes.It is also in talks with privately held Swift & Co.,
the world's second-biggest beef and pork processor, to
extract methane from processing wastes that would
otherwise be tossed into landfills.Story by Timothy GardnerREUTERS NEWS SERVICEmore at websitefunction GoToContent() { selection = document.siteLinks.selectLink.options[document.siteLinks.selectLink.selectedIndex].value; if (selection == "none") { return; } if (selection.indexOf("http:") != -1) { location.href = "" } else { location.href = "" + selection; } } function GoToSearch() { location.href = "" + escape(document.searchLinks.searchLink.options[document.searchLinks.searchLink.selectedIndex].value) } ![]()
