BLOOMFIELD, Conn. -- A Bloomfield bakery that churns out about 160 loaves of bread per minute is going green.

The Pepperidge Farm Bakery is switching to fuel cells. It already has one fuel cell in place and has another one on order.

Plant officials said switching to fuel cells will help the company save on electricity.

They said that the plant will go from spending 14 cents a kilowatt hour to around 10 cents, which will equal about $1 million a year.

A fuel cell works by putting natural gas, methane, propane into a fuel processor that removes the hydrogen. The hydrogen then mixes with air which then passes into the fuel cell, producing electricity.

The company is purchasing the second fuel cell with a $3.5 million grant from the Connecticut Clean Energy Fund. When the second fuel cell is brought online, the pair will provide about 70 percent of the plant's electrical needs.

The fuel cell byproducts won't be wasted, according to officials.

The company said another reason it is switching to fuel cells is because of their reliability. The fuel cells won't fail in a thunderstorm.
