Fuel Cells and UPS
Thursday, November 29th, 2007
I read in the press that the South Gare lighthouse, at the mouth of the River Tees in North East England, is now being powered solely by a hydrogen fuel cell. The technology was developed by the Centre for Process Innovation at Wilton. The lighthouse is 120 years old and is regularly lashed by high winds and rough seas. The fuel cell has been developed to withstand such conditions. Another development comes from USA-based Protonex Technology who, in partnership with AeroVironment, have developed a fuel cell system that has kept an unmanned aerial vehicle in the air for several hours – a significant improvement on the two hours so far achieved by earlier technologies.
Fossil fuels are running low, we know that, so alternatives have to be sourced but are fuel cells really in the running? First invented by Sir William Robert Grove in 1839, in recent years their development has centred primarily on military applications, although the last few years has seen a rash of activity in the leisure industry with companies, such as Voller Energy, developing fuel cells that run on natural gas, which can then be used by caravan and boat enthusiasts. Replacing generators as an alternative source of back-up power still seems a long way off. Fuel cells are expensive to manufacture and run plus their environmental credentials are questionable. They run on hydrogen, hydrocarbons, alcohol and chlorine or chlorine dioxide, which are pretty potent chemicals that have to be sourced, stored and disposed of. Conversely, a fuel cell can be compact, lightweight and, as it has no major moving parts, extremely reliable.
Where the normal mains power supply is unreliable and there is a suitable supply of natural gas, fuel cells can be advantageous as an alternative source of ac power although a battery set will still be required. It will be a while before they enter the mainstream UPS market. For more information on fuel cells and alternative power sources, see The Power Protection Guide
‘Tis the season to be jolly – and why not? You’ve worked hard all year; you deserve to ease off the peddle in December. Trouble is, that’s when people often become less vigilant and succumb to the distractions of the season; parties, shopping, planning the holiday, tying up loose ends and so on. It takes the focus away from

A report the other day stated that oil production and demand will max out within 10 years. After this we can expect a slow reduction in oil production and the need to (1) develop technologies to make more use of heavier oils that we will require even more energy to turn them into useable fuels, and (2) move further towards renewables. Riello UPS is already working within the solar energy field and has an exciting
Wednesday saw the final event in our 2008 Power Protection and Business Continuity roadshow. We closed the season at Old Trafford which remains a favourite venue for Riello UPS for a number of reasons. Our seminars are always well received and this is in no part thanks to the partners we work with who include some of the leading companies within the power protection field – UPS Systems, Vycon, Cummins, PFC Engineering, Furse, Secure IT, Denco and Sinetica. Thank you to everyone who attended. We will be posting podcasts of the various presentations to a new TEC website during 2008 and announcing details of next year’s programme in due course. In the mean time if you have any specific questions on UPS, power factor correction, generators, fly wheels, lightning protection, secure data environments, air conditioning or remote monitoring please
