Online commerce giant eBay (Nasdaq: EBAY) on Thursday announced that it will expand its flagship data center in Utah and use renewable energy to power the addition.

This expansion will use 30 Bloom Energy fuel cells and will be the largest non-utility fuel cell installation in the United States.

The fuel cells will be the primary source of energy for the facility — the electric utility grid will only be used as backup.

“We intend to shape a future for commerce that is more sustainable at its core,” Dean Nelson, eBay’s vice president of global foundation services, told TechNewsWorld.

“Through this project, we are enabling every transaction that goes through our Utah data center to be clean,” he added.

“The only end products from a fuel cell electricity production process are the electricity, water and some heat,” John Rogers, a senior energy analyst with the Union of Concerned Scientists (UCS), told TechNewsWorld. “If the fuel cell’s source is from a sustainable source, then it can be a very attractive option from an environmental perspective.”
