Thus, in this system, hydrogen is used as a long-term energy storage option, whereas the battery is utilised as a short-term option. As a result, the contribution of electricity supply by the grid in Fig. 14 c is significantly reduced when compared to the battery-only and hydrogen-only cases in Fig. 12 c and Fig. 13 a.

Modelling of hydrogen energy storage system The HESS consists of a proton exchange membrane electrolyser (PEMEL), storage tank, and proton exchange membrane fuel cell (PEMFC), as shown in Fig. 3. The HESS is flexible to combine different charge power, discharge power and storage capacity because of the modularity and independence of each component.
Li-ion batteries are deployed in both the stationary and transportation markets. They are also the major source of power in consumer electronics. Most analysts expect Li-ion to capture the majority of energy storage growth in all markets over at least the next 10 years , , , , .
As illustrated in Fig. 11, the Hybrid ESSs are still the best energy storage solution in this analysis. Interestingly, the HESSs perform better than the BESSs in MEL in this ultimate cost scenario, showing the potential of using hydrogen as a long-duration ESS in locations with high seasonal variations.
Also, due to internal chemical reactions, the energy stored in BESS is reduced even without any connection between the electrodes or any external circuit. A self-discharge rate r SD of 0.004 % per hour (equivalent to 2.9 % per month ) is used in the BESS model. 3.2.2. Modelling of hydrogen energy storage system
