Microsoft sees huge potential in fuel cells

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

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.

If the fuels are distributed in a data center, and placed at the servers and racks, "we can completely eliminate the power distribution system in the data center, including the power backup generation." If a fuel cell fails it only affects a small part of the data center, the report reasoned.

There's trade-off in cost with using smaller fuel cells to power individual pieces of equipment. Also, smaller fuel cells used at a server cabinet level may be unable to keep with an almost instantaneous rise in server load.

James says that fuel cells can double the efficiency of traditional data centers, and are also environmentally friendly, even when they use natural gas.

The cost benefits are a moving target, though the paper assumes that they will improve as the industry grows.

Fuel cells are seeing high growth, according to the U.S. Dept. of Energy, in a report last month. Total fuel shipments increased 34% in 2012 over 2011.

Approximately 30,000 fuel cell systems were shipped in 2012, up from 5,000 in 2008.

Examining the changing job scene in the Kiwi channel

Typically, the New Year brings new opportunities for personnel within the Kiwi channel. 2017 started no differently, with a host of appointments, departures and reshuffles across vendor, distributor and reseller businesses. As a result, the job scene across New Zealand has changed - here’s a run down of who is working where in the year ahead…

​What are the top 10 tech trends for New Zealand in 2017?

Digital Transformation (DX) has been a critical topic for business over the last few years and IDC is now predicting a step change as DX reaches macroeconomic levels. By 2020 a DX economy will emerge and it will become the core of what New Zealand industries focus on. From the board level through to the C-Suite, Kiwi organisations must be prepared to think and act digital when the DX economy emerges in 2017.

Top 15 Kiwi tech storylines to follow in 2017

​The New Year brings the usual new round of humdrum technology predictions, glaringly general, unashamedly safe and perpetually predictable. But while the industry no longer sees value in “cloud is now the norm” type projections, value can be found in following developments of the year previous, analysing behaviours and patterns to formulate a plan for the 12 months ahead. Consequently, here’s the top Kiwi tech storylines to follow in 2017...
