California cows start passing gas to the grid
RIVERDALE, California (Reuters) - Imagine a vat of liquid cow manure covering the area of five football fields and 33 feet deep. Meet California's most alternative new energy.
On a dairy farm in the Golden State's agricultural heartland, utility PG&E Corp began on Tuesday producing natural gas derived from manure, in what it hopes will be a new way to power homes with renewable, if not entirely clean, energy.
The Vintage Dairy Biogas Project, the brainchild of life- long dairyman David Albers, aims to provide the natural gas needed to power 1,200 homes a day, Albers said at the facility's inauguration ceremony.
"When most people see a pile of manure, they see a pile of manure. We saw it as an opportunity for farmers, for utilities, and for California," Albers said.
In addition to being a partner in the 5,000-head Vintage Dairy, Albers is also president of BioEnergy Solutions, the company that funded and built the facility which cost millions of dollars. PG&E is simply a customer and the companies declined to give details of project finances.
As cow manure decomposes, it produces methane, a greenhouse gas more potent than carbon dioxide. Scientists say controlling methane emissions from animals such as cows would be a major step in addressing climate change.
