Availability Explanation:

The system availability is the lowest due to the dependence on weather conditions.

The system availability is justified due to the fuel cell offering back-up capacity for the system.

The system availability is justified due to the increased number of fuel cells offering back-up capacity for the system.

Advantages +

 

+ Self sustained off-grid solution
+ Reduced O&M cost
+ No fuel
+ Long system life-time (15 years)

 Self-sustained off-grid solution
+ Reduced O&M cost
+ Silent
+ Long system life-time (15 years)
+ Increased system availability (less weather dependent)
+ Reduced installation footprint
+ Reduced design activities (standard solutions available)

 

+ Self-sustained off-grid solution
+ Reduced O&M cost
+ Low CAPEX costs
+ Silent
+ Long system life-time (15 years)
+ Increased system availability (not weather dependent)
+ Extremely reduced installation footprint/weight
+ Reduced design activities (standard solutions available)

Disadvantages -

- System availability is weather dependent.
- Installation footprint must be assessed for each project
- Ad-hoc design required
- High CAPEX costs

- Eco-fuel dependent*
*classed as disadvantage but simple to overcome in line with standard maintenance activities

- Eco-fuel dependent*

 

Suitability Examples:

 

  • Highly predictable and good weather conditions, e.g. MENA region
  • High footprint available

 

  • Suitable for unpredictable weather conditions, e.g. North Sea/Canada
  • Limited footprint available

 

  • Suitable for unpredictable weather conditions, e.g. North Sea/Canada
  • Limited footprint available
  • Higher system availability and autonomy requirements
