The document complements a separate analysis of the opportunities for hydrogen transport applications. There are a number of drivers for consideration of fuel cells in stationary power applications at Heathrow. Key drivers include: • Reduction of CO2 emissions – Fuel cells offer the potential to reduce Heathrow’s CO2 emissions through more efficient heat and power generation. • Air Quality improvement – Use of fuel cells produces fewer NOx and particulate emissions, compared to incumbent systems. • Reliability and availability – Fuel cells can outperform batteries and gensets in certain critical back-up applications. • Low noise – Noise pollution is a significant issue at Heathrow. Fuel cells offer very quiet operation compared to incumbent gensets. • Integration with waste processing – Fuel cells could deliver benefits as part of an integrated waste management system at Heathrow • Synergy with transport applications – Adoption of hydrogen in both stationary and transport applications could be mutually beneficial 3 Introduction: Potential applications There are a range of potential applications around Heathrow where fuel cells could play a role: Prime and back-up power – diesel gensets are currently employed in a number of back-up power applications and there is interest in use of on-site generation in a peak-shaving mode (i.e.
