Fuel Cell-Powered Data Centers Could Cut Costs and Carbon
angry tapir writes "A group of Microsoft researchers believe that using fuel cells to power data centers could potentially result in an 'over 20% reduction in costs using conservative projections', cutting infrastructure and power input costs. In addition, using fuel cells would likely result in a smaller carbon footprint for data centers. The researchers looked at the potential of using fuel cells at the rack level to power servers in data centers — although they note there is a long way to go before this could become a reality (not least of the small worldwide production level of fuel cells)."
Give me a call when those fuel cells are ready for deployment, then we can talk about all these wonderful uses. No talk about the carbon footprint of operating fuel cells?
The article mixes the use of fuel cells as a power source with efficiency improvements. The only place that makes sense is with the minor savings that may be seen by eliminating DC converters, but you will still need DC regulators which will have some losses.
A major oversight of this article is the fact that fuel cells are major heat generators, not something you want in a data center. They would need to be installed in a separated structure, therefore idea that "Rack-level fuel cells would do away with data-centre-wide electricity distribution for servers" is hard to imagine.
