Why eBay is powering its Utah data center with fuel cells

In Utah, 94 percent of the energy produced comes from coal. That’s not the case at eBay’s (s ebay) data center, where fuel cells will use natural gas to power servers.

“The cost of electricity in Utah is low. It’s dirty and cheap. But that’s not what we want,” eBay vice president Dean Nelson said Thursday at the GigaOM Structure conference.

Instead of one large generator, 6 MW of smaller fuel cells will give the data center the flexibility to roll with unexpected power challenges. If one cell goes down, the facility loses a small amount of capacity instead of power altogether. The grid will function as a backup to the cells, and computers will consume energy 100 feet from where it’s generated.

“We’re challenging fundamentally how we’ve all done it for the last 30 years,” he said.

Bloom Energy vice president Peter Gross, who co-presented with Nelson, said natural gas has changed the power situation completely for data centers. They now have the ability to lock in energy costs for a period of 15 years. He said he was surprised by how rapidly the fuel cells were embraced by the data industry.

“We’ve been very public about this project because we do believe it starts the right dialogue,” Nelson said. “We’re proving this can be done this way.”

    Use the grid as back up? Even though they just pointed out electricity is really cheap in utah? you can also use a bunch of small generators. Argument doesn’t make much sense, so what is the real reason? Because we know its not cost…..or was it subsidized?

      You’re missing the point. Using the grid as backup means exactly that… They are primarily powered by the fuel cells, and in the event of a fuel cell failure, they switch seamlessly to the regular grid. A fuel cell is way cheaper (in total cost of ownership) and more reliable than “a bunch of small generators”.

      It is really, really important to them that the power never goes out, and they are willing to pay a premium for it. They are in Utah for the cheap grid power, and use fuel cells which are the cheapest way to get 99.99%+ reliability.

        Off topic; For the call center on that same site they installed two 1MW Generac Gemini generators. Generac parallels the generators using controls and switching in the generators themselves. This allows feeding redundant paths and N+1 capacity very easily.

    • Generator is just burning the fuel to generate power, not efficient and clean. Fuel cell generates power in a chemical way, very efficient and clean.
