Hydrogen Fuel Cells: Unlimited UPS (Sep-04)

Uninterruptible Power Supply (UPS) allows computer systems to keep running for a short time even if a facility loses power, the advantage being that the user has time to save data before the power cuts out. In the past UPS systems have relied on battery or diesel generators, however, advances in hydrogen fuel cell technology have provided a more environmentally friendly solution. The advantage of using hydrogen is that there is no CO2 emitted, it runs very quietly and it lasts for ten years as opposed to batteries which last three or four years.

The disadvantage of hydrogen is that it is not very cost competitive for short runs when compared to other UPS options, thus the future of hydrogen becoming a major player in the economy will depend upon producing, supplying and storing the element at a low cost for end users.
