NTT America Data Center to be Powered by Biogas, Bloom Servers

by | Aug 2, 2011

Japanese telecommunications company  NTT America has deployed five Bloom Energy Servers running on directed biogas, at its Lundy Data Center in San Jose, Calif. The energy servers are connected to a natural gas pipeline, and use biogas from a California dairy farm to generate electricity on-site.

The five servers have a total capacity of 500kW (kilowatts), and will produce over 4.2 million kilowatt-hours annually, while reducing carbon dioxide emissions by 1.6 million pounds.

The deployment is part of NTT America’s energy efficiency initiatives, the fuel cell option reduces the dependency on the public electric grid, minimizing the company’s carbon footprint by using renewable fuels, as well the use of biogas further reduces dependency on fossil fuels, the company said.

According to Reuters, many Bloom fuel cells are powered by natural gas, and each Bloom fuel cell costs around $700,000 to $800,000 before subsidies, so NTT is spending a couple million dollars on the green data center.

Other energy efficiency measures used at the data center include hot aisle/cold aisle server rack design, aisle containment solutions, high efficiency computer room air conditioner (CRAC) cooling systems, distributed electricity generation and dynamic temperature sensor/control technology, the company said.
