Will curb carbon footprint by 50 percent
AT&T has signed a deal with Bloom Energy to install oxide fuel cell technology at 11 of the company's sites in California. All told, the Bloom Energy Servers, or Bloom Boxes, will generate 7.5 megawatts of power with 50 percent lower CO2 emissions than conventional fossil power generation. This is equivalent to taking more than 3,700 cars off the roads, AT&T claimed.
The Energy Servers contain stacks of fuel cells that convert air and natural gas into electricity through a clean electrochemical process. They will help AT&T avoid generating approximately 250 million pounds of CO2. The process also creates energy without sulfur and nitrous oxide byproducts (smog) often associated with power creation. AT&T hopes to generate 62 million kilowatt-hours of energy annually, enough to power over 5,600 homes.
The 11 AT&T facilities include Corona, Fontana, Hayward, Pasadena, Redwood City, Rialto, San Bernardino, San Diego, San Jose, and San Ramon. Installation will begin later this year with a target completion of the project sometime in mid-2012.
