Microsoft Sees Huge Potential in Fuel Cells

Fuel cells may be a strong alternative for powering data centers, Microsoft report concludes.

Computerworld — Microsoft is touting the use of fuel cells to power data centers, arguing in a paper released Tuesday that its studies find it a technology with much potential.

The paper, boldly titled "No more electrical infrastructure: Towards fuel cell powered data centers," investigates fuel cells as a centralized power source and as distributed power generation technology with fuel cells used at the rack or single server cabinet level.

There is broad industry interest in fuel cells.

In September, eBay unveiled a data center in Salt Lake City Utah that uses fuel cells made by Bloom Energy.

But overall, use if the technology in data centers remains far from mainstream.

Sean James, a senior research program manager at Microsoft's Global Foundation Services and an author of the study, said in a blog post that he sees "tremendous potential" in fuel cells, though "deep technical issues" remain.

"Fuel cells are very clean, reliable and perfect for small form factor applications," wrote James. "By integrating fuel cells with IT hardware, we can cut much of the power electronics out of the conventional fuel cell system. What we are left with is a very simple and low cost data center and fuel cell system."

Technical issues, such as the fuel distribution system, power management and even safety training, remain to be resolved, he notes.

Nonetheless, James argues, in time, "you may end up with one someday delivering clean electricity and heat to your home" via fuel cells. Fuel cells, an electrochemical process to convert energy from hydrogen, natural gas, ethanol or biogas. The eBay facility uses biogas, which comes from agricultural waste.

The paper looks at running an entire data center on fuel cell technology and decoupling data centers from the electric grid. If fuel cells use natural gas, the buried lines delivering it are "not subject to severe weather."

Indeed, in a report released in August, the White House Council of Economic Advisors said severe weather is the number one cause of power outages in the U.S.. The report added that "the number of outages caused by severe weather is expected to rise as climate change increases the frequency and intensity of hurricanes, blizzards, floods and other extreme weather events."

The council's report argued for increased spending on grid improvements.

Fuel cells are "much cheaper" than high voltage switchgear, transformers and copper cables, and have no moving parts, unlike generators, the Microsoft paper argues.
