The hydrogen tank autonomy is the ratio of the energy capacity of the hydrogen tank to the electric load. HOMER calculates the hydrogen tank autonomy using the following equation:

equations_A_htank

where:


 

 

Yhtank

= capacity of the hydrogen tank [kg]

 

LHVH2

= energy content (lower heating value) of hydrogen [120 MJ/kg]


Lprim,ave

= average primary load [kWh/d]
