The degree of self-sufficiency (Φ) [Eq. 1] describes the portion of electric energy that is no longer purchased from the grid (E grid) as a result of the electricity generated on-site can be calculated by the ratio of the PV energy consumed directly (E dir) or taken from the storage (E discharge) and the whole energy demand of the household (E load).
This is primarily because the energy cost for battery storage increases significantly with its capacity, whereas the cost of hydrogen storage is relatively stable due to the lower cost of H 2 tanks. Such a cost structure makes battery energy storage economically infeasible for long-duration applications. Specifically, the battery-UHV pathway outperforms …
