Techno-economic study of a PV-hydrogen-battery hybrid system for off-grid power supply: Impact of performances' ageing on optimal system sizing and competitiveness

The PV-Batteries-H2 system is operated by an efficient power management strategy and its optimal sizing is assessed on the basis of technical (e.g. load satisfaction) and economic (e.g. levelized cost of electricity) criteria. The results highlight the important role of the hydrogen chain in reducing the cost of the supplied energy. It is also shown that performances degradation of the hydrogen chain has a limited impact on the system optimal sizing and economic results.
