“…The curtailed renewable power and the fact of its intermittency is the biggest barrier delaying the transition towards 100% of renewable power penetration into the power systems [6]. The storage systems will need to store and shift the RE generated power on different time scales, i.e., hourly, daily and seasonally [7,8]. The conventional energy storage systems like batteries, pumped-hydro, mechanical, etc.…”

“…These limitations raise the necessity for a new approach to store energy in an environmentally friendly way, large-scale capacity and longer discharge duration [9][10][11]. Hence, the innovative idea of storing RE in an energy carrier such as hydrogen, which is storable, transportable and utilizable has encouraged interest worldwide recently [7]. Robust energy storage technology with an intelligent and integrated control system is an urgent requirement today to increase the penetration of RE into the energy mix.…”

“…Renewable energy storage systems (RESS) play a crucial role in maximizing the RER contribution to the SAM energy balance. Such RESS solutions can be a hybrid combination of more than one technology working together in a synergistic way [7,21]. However, the classic trend is to use a conventional diesel generator (DG) as a backup or to meet the peak load in combination with RESS for the optimal energy system component sizing to minimize capital cost [16,17,[21][22][23][24].From the available researches, it is evident that SAM with a high percentage of RE penetration and hybrid RESS can be reliable, cost-effective and more sustainable compared to a 100% fossil-fuel-based SAM [25].…”

“…This system is called power to hydrogen to X (X means different applications depending on the hydrogen utilising pathway or end-use) [5,16,18,[35][36][37][38][39]. The novel concept of power to hydrogen to power (P2H2P) is a promising option for storing intermittent renewables and regenerating power when needed [7].In this research, a remote community SAM has been proposed to identify the techno-economic viability of a 100% RE-based system with hydrogen-battery energy storage. In Western Australia (WA), there are dozens of remote stand-alone electricity grids that are beyond the State's main utility grid, the South West Interconnected System (SWIS) [40,41].…”

A 100% renewable energy-based stand-alone microgrid system can be developed by robust energy storage systems to stabilize the variable and intermittent renewable energy resources. Hydrogen as an energy carrier and energy storage medium has gained enormous interest globally in recent years. Its use in stand-alone or off-grid microgrids for both the urban and rural communities has commenced recently in some locations. Therefore, this research evaluates the techno-economic feasibility of renewable energy-based systems using hydrogen as energy storage for a stand-alone/off-grid microgrid. Three case scenarios in a microgrid environment were identified and investigated in order to select an optimum solution for a remote community by considering the energy balance and techno-economic optimization. The "HOMER Pro" energy modelling and simulating software was used to compare the energy balance, economics and environmental impact amongst the proposed scenarios. The simulation results showed that the hydrogen-battery hybrid energy storage system is the most cost-effective scenario, though all developed scenarios are technically possible and economically comparable in the long run, while each has different merits and challenges. It has been shown that the proposed hybrid energy systems have significant potentialities in electrifying remote communities with low energy generation costs, as well as a contribution to the reduction of their carbon footprint and to ameliorating the energy crisis to achieve a sustainable future.A modern microgrid is an integrated energy system consisting of localised grouping of distributed electricity generation with storage and multiple electrical loads [11,12]. It can be controlled as one entity or grid, either standalone, completely separate from, or connected to, the existing utility grid [13]. The development of the microgrid has been largely dominated by energy demand-side management, RE penetration and its integration into the utility grid [14,15]. In cases where it is not possible to connect the microgrid to the utility grid for any reason such as the remote or isolated location, a stand-alone microgrid (SAM) is an answer to the power supply challenges [16]. The authors of this research envisioned that the SAM is a good starting point to transit from the classic trend of fossil-fuelled powered systems to 100% RE powered systems.The SAM is a low-voltage power system that supplies a specific localised area [17]. It comprises local power generation systems with load demands, that can operate in islanded mode or off-grid [18,19].In the transition to a 100% RE SAM system, hybrid distributed (decentralized) or centralized energy generation and storage systems are used to meet the energy need [18]. The SAM is presented as a viable and effective solution to the utilisation of renewable energy resources (RER), by minimizing the problems associated with variability and intermittency of the renewables [16]. The main challenge in a SAM system is the optimal sizing of the system components to make the...
