A new reason to use fuel cells for data centers: fire prevention

Data center operators have been experimenting with using fuel cells to increase the use of off-grid energy and cleaner power. But at least one data center operator is citing yet another reason for installing a fuel cell system in its data center in Frankfurt, Germany: fire prevention.

Earlier this month Equinix announced that it’s installed a fuel cell at its FR4 data center, which will be able to generate 800,000 kilowatt hours of electricity per year and another 600,000 kilowatt hours kilowatt hours/a of heating. The fuel cell was made by Japanese giant Fuji Electric and was installed by German project developer N2telligence.

Fuel cells are industrial units that take fuel, usually natural gas or biogas, and combine it with a catalyst to produce electricity and heat. Because the boxes are installed close to the source that uses the power they can be more efficient (energy isn’t lost over transmission lines bringing the power to the data center), and because natural gas and bio gas tend to emit less carbon than grid coal power, they can be cleaner, too.

Beyond the fact that fuel cells can be cleaner and more efficient, data center companies like eBay and Microsoft have been using them as a way to take smaller data centers off the grid. That way they are more resilient if the grid goes down.

Equinix says in addition to resiliency and environmentalism, it’s also using the fuel cells for the more unusual reason of fire prevention. The company says the Fuji Electric fuel cells produce nitrogen-rich air that can fill buildings and help prevent fires. Fires are relatively rare in data centers, but when they happen they can bring down internet companies services.

Equinix says that because of the fire prevention aspect, this installation is the only one in the world with this high level of data center integration. Equinix and N2telligence will be monitoring the fuel cells, and the project was created in conjunction with the Hydrogen and Fuel Cell Initiative Hessen (H2BZ).
