Through a comparative analysis of current storage technologies, several key findings have emerged: PHS Superiority: It became evident that Pumped Hydro Storage (PHS) holds distinct advantages over Hydrogen (H 2) storage in two critical areas: efficiency and environmental impact.
For long-term deployment, the picture changes. While pumped hydro storage remains a viable option, other storage systems like compressed air and hydrogen may become more cost-effective. For medium-term deployment, there are reductions in LEC of around 40% for pumped hydro, 45% for compressed air storage and 70% for hydrogen storage.
Based on the assumptions made for 2030, hydrogen storage surpasses pumped hydro in terms of average, discounted costs of energy storage. Even the costliest variant of hydrogen storage is only half the cost of pumped hydro.
Any surplus energy generated by the system is channelled to an electrolyzer, which produces hydrogen. This hydrogen is then stored in a dedicated tank for future use.
For each type of activity, it is readily apparent that these NPC and COE values are lesser than those of PV/HES and Wind/HES systems. For this reason, among the systems that make use of pumped hydro energy storage, the PV/Wind/HES system appears to be the most appropriate option.
Currently, hydrogen storage is not cost-competitive in short-term storage (STS) and medium-term storage (MTS) deployment scenarios. In these scenarios, pumped hydro and compressed air storage are more cost-effective.
