Particularly for small-scale stand-alone renewable energy systems, energy storage has become essential in providing electricity when the demand is high, for example, during the night. Although there are many different storage technologies, only a few are suitable for small-scale stand-alone renewable systems.

One disadvantage of small pumped hydro energy storage is the investment cost, given the low storage capacity. Small PHES indeed suffers from scale effects [13] . The method developed considers natural opportunities, such as existing lakes and natural terrain depressions, which could be operated at a limited cost.
Large-scale hydropower has several advantages such as: 1. Cost-Effective. Large-scale hydropower is considered to be one of the least expensive forms of renewable energy. Once the initial construction cost is covered, there are few maintenance costs and no fuel costs since water is the fuel used to generate energy. 2.
Large scale storage provides grid stability, which are fundamental for a reliable energy systems and the energy balancing in hours to weeks time ranges to match demand and supply. Our system analysis showed that storage needs are in the two-digit terawatt hour and gigawatt range. Other reports confirm that assessment by stating that
1. Introduction Hydrogen is attracting global attention as a key future low-carbon energy carrier, for the decarbonisation of transport, power and heating, and of fuel-energy intensive industries, such as the chemical and steel industries. 1–5 The United Nations Industrial Development Organisation 6 has defined hydrogen as "a true paradigm shift in the area
The promise of large-scale batteries. Poor cost-effectiveness has been a major problem for electricity bulk battery storage systems.
