A growing number of livestock farms are installing digesters to trap methane gas and turn it into sustainable energy.
When cow manure decomposes, it releases methane gas. The EPA says it's 25 times more potent than carbon dioxide at trapping heat in the atmosphere.
The anaerobic digester on the farm can hold up to 25 million gallons of manure and water. The EPA explains anaerobic digestion as a process through which bacteria break down organic matter in the absence of oxygen inside a sealed vessel."About 15 years ago, we started hearing about digesters and became intrigued because one of the biggest costs that we face on the dairy is our power costs," Shehadey said.
"I think what makes our project unique is the fuel cell," Shehadey said."The fuel cell is the first of its type to run on biogas from a dairy. You know, these fuel cells, Bloom Energy has several hundred of these throughout the country, but normally they run on natural gas. And so, this, they took it one step further to take methane from a dairy. And instead of using natural gas, they use cleaned-up methane to produce energy, and as it's near zero emissions.
Shehadey says the annual carbon emission reduction is equivalent to providing clean power to more than 17,000 electric cars per year.
