As lawmakers in Washington, D.C., debate new federal climate-change legislation, Wisconsin's dairy industry is leading the way in demonstrating the benefits of using cow manure methane digester biogas. In the last several years, a growing number of dairy farms in Wisconsin have installed GE Energy's Jenbacher biogas engines to generate needed renewable electricity for onsite power and the local grid.
GE's newly installed, advanced Jenbacher biogas engine technology is generating 633 kilowatts (kW) in renewable energy at the Crave Brothers Farm, LLC in Waterloo, Wisc..
"Installing GE Energy's Jenbacher biogas technology is playing an important role in our ongoing initiatives to reduce the operational costs as well as the environmental impacts of our dairy operations," said Charles Crave, one of the farm's co-owners. "We hope that other dairy farms around the country adopt similar technologies in recognition of the agricultural community's increasingly important role in addressing the country's energy and climate-change concerns."
This week, Crave Brothers is hosting the 2009 Farm Technology Days, one of the country's largest agricultural technology expositions. More than 80,000 people are expected to visit the Crave Brothers site, which is located about an hour west of Milwaukee.
Crave Brothers is a 29-year-old, family run dairy farm and on-site cheese plant that is nationally known for its progressive use of technologies to reduce the environmental impacts of its operations. The 1,700-acre farm currently has nearly 1,000 milk cows and 700 heifers.
By converting the manure to methane biogas and using it to generate electricity in GE's Jenbacher unit, less greenhouse gas is able to escape into the atmosphere. The system also is helping Crave Brothers lower its operational costs, including through the sale of energy to the regional grid and more cost-effective manure management.
Crave Brothers originally had operated an older, less powerful biogas system to support some of the farm's electricity requirements. However, the owners later installed GE's Jenbacher technology after deciding they could be generating even more electricity with a more powerful Jenbacher engine, Crave said.
In May 2009, one of GE's ecomagination-certified Jenbacher J312 biogas engines was commissioned at the Crave Brothers site and is generating 633 kW of electricity to support the site's dairy operations. Surplus power from the engine is being sold to the regional grid in Wisconsin, which is aggressively supporting the expansion of renewable energy production.
