abstract = {The current need to reduce carbon emissions makes hydrogen use essential for selfconsumption in microgrids. To make a profitability analysis of a microgrid, the influence of equipment
costs and the electricity price must be known. This paper studies the cost-effective electricity price
(EUR/kWh) for a microgrid located at ‘’La Rábida Campus” (University of Huelva, south of Spain),
for two different energy-management systems (EMSs): hydrogen-priority strategy and batterypriority strategy. The profitability analysis is based, on one hand, on the hydrogen-systems’ cost
reduction (%) and, on the other hand, considering renewable energy sources (RESs) and energy
storage systems (ESSs), on cost reduction (%). Due to technological advances, microgrid-element
costs are expected to decrease over time; therefore, future profitable electricity prices will be even
lower. Results show a cost-effective electricity price ranging from 0.61 EUR/kWh to 0.16 EUR/kWh
for hydrogen-priority EMSs and from 0.4 EUR/kWh to 0.17 EUR/kWh for battery-priority EMSs
(0 and 100% hydrogen-system cost reduction, respectively). These figures still decrease sharply if RES
and ESS cost reductions are considered. In the current scenario of uncertainty in electricity prices, the
microgrid studied may become economically competitive in the near future},

developed the software with which a simulation of the described microgrid was performed, which
subsequently led to the profitability study carried out in this paper},
