Results and Discussion for the System of Fair Isle

The analysis of both the existing wind-diesel autonomous power system and the proposed hydrogen-based power system of Fair Isle was conducted with the HOMER simulation tool. The detailed results of the analysis are presented in the following sections.

Similarly to the analysis of all other case studies, the objective of Fair Isle s autonomous power system simulation was the identification of all important operational parameters that will be used as a basis for comparison to the proposed hydrogen-based autonomous power system described in the next section. 

The analysis of Fair Isle s power system, which is currently in operation revealed that it produces 767,804 kWh per year, 92% of which is produced by the wind turbines. The analysis results related to electricity production and demand for the existing system of Fair Isle are summarised in Table 5.7. 

Therefore, we can conclude that there is a high potential for the introduction of hydrogen energy technologies in the system of Fair Isle in order to take advantage of the huge amount of excess electricity currently produced and dumped on the island.
