Full article: Fujitsu gets cleaner datacentre power from fuel cell (20-Aug-07)
Fujitsu America has become the first Silicon Valley company to install a hydrogen fuel cell to provide power to its data centre and other operations. The fuel cell provides half of the data centre's cooling electricity needs. The company said that it will take three and a half years to get a return on the investment.
A fuel cell generates electricity and heat as by-products of an electro-chemical reaction between fuel and an oxidant in the presence of a catalyst or electrolyte. As long as fuel and oxidant (reactants) flows in and the reaction product flows out then electricity production is continuous.
Much of the heat produced by the fuel cell can't be used by Fujitsu and is just vented away. Fujitsu states that the fuel cell produces 35% less CO2 per megawatt-hour than the average fossil fuel-based power plant, and approximately 4,000 lbs per year less Nitrous Oxide, the equivalent of taking more than 100 average passenger cars off the road.
