- Load following – no over engineering
- Silent
Who uses fuel cells?
- Emergency services
- Communications networks
- Rail and transport
- Data centres
- Finance
- Marine
- Residential
- Space
- Military
What are the most common types of fuel cells?
- Alkaline
- Molten Carbonate
- Phosphoric Acid
- Proton Exchange
