SSE Fuel Cell Energy Experience
- 1. Selecting, installing and life after – Why SSE chose fuel cell energy for their service centre and their experiences to date. David Farr – project manager
- 2. Penner Road Havant, Hants. Refurbished factory completed 2009 2500 seat call centre and office. +/-1 MW load. Open 07.00 – 20.30 6 days per week
- 4. Design Plan well ahead – we added the fuel cell at a late stage. Mode of operation – decision as to use of ‘waste’ heat. Absorption vs adsorption chiller. Grid connected or not etc Planning issues – Concerns re location, noise, COSHH, discharges, legionella, explosion. Other plant - Interconnection, heat exchangers, Gas supply
- 5. Pre Installation Testing of plant – PUWER, Electrical, CE compliance. Substantial base – machine weighs +/- 20 Tonnes.
- 6. Installation Usual H&S issues, CDM Building shut down to allow fuel cell connection
- 7. Commissioning Plumbing, - straightforward nothing out of the ordinary Electrical, normal as above – add involvement of your local network operator for parallel operation of plant and certification of emergency cut off relays. Fire alarms & BMS – just add to the complexity Gas, meter with BMS mode Fuel Cell & Chiller – both items of a specialist nature with limited number of available technicians
- 8. Operation Fuel cell is very sensitive to supply voltage. The voltage from our substation was 10 volts above nominal; caused nuisence trip outs. Had to re-set tappings on transformer. Absorption chiller seems more sensitive to water temperatures than normal compressor types.
- 9. Lessons learned Things take longer than you first expect. Fuel cells may not be new technology – but assume they are. The larger the fuel cell, the fewer have been made and the less anyone knows. For most spares you have only one source of supply, they are likely to be slow to arrive and costly.
