Alternative power generators form the basis of reliability, affordability, and sustainability in accessing rural and urban communities from developing or developed countries (with minimized emission of gases) in connection and isolation from the utility grid system. Econometrics and energy assessment of an integrated hybrid renewable energy-power reserve network was analyzed with grid mode connection in Ko-Kut Island (Thailand) from this paper. Hybrid energy-power sources (solar photovoltaic energy, utility grid, biomass resources fueling biogas energy system, wind energy turbine and high energy flywheel) and a unified power reserve unit (vanadium redox flow: VRXFB-, sodium sulphur: NaS-, Li+: lithium-ion-, ZnBr: zinc bromide flow batteries) was designed to effectively manage the energy flow linking the unified generators and the needed energy from the island. A combined dispatch energy controller was used as an interactive controller system across the generators-, batteries-, and load to enhance the unified energy system's flexible operation into four different configurations in other to investigate their energy cost, net present service cost, energy sales, energy purchase from the utility grid, and estimated operational cost performance, respectively. In addition, an optimized power management control algorithm was designed with microgrid power analysis software (HOMER) to determine the most economic and efficient generating system architecture. It was observed from the optimization result that the architecture of VRFB energy system had the least energy tariff

With the expansion of renewables in the electricity markets, research on electricity storage economics is needed for a better understanding of the utilization of these systems and for improving the performance of intermittent variable generation. Collected up-to-date research of electricity storage systems published in a wide range of articles with high impact factors gives a comprehensive review of the current studies regarding all relevant parameters for storage utilization in the electricity markets. Valuable research of technical characteristics from the literature is broadened with the electricity storage analyses from an economic point-of-view. Analysis of selected technologies, considering different perspectives such as their profitability, technical maturity, and environmental aspect, is a valuable addition to the previous research on electricity storage systems. Comparing conducted analysis with the selected literature, electricity storage technologies are analyzed concerning their viability in the electricity markets. Given the current outlook of the electricity market, the main problems for storage's wider integration are still energy storage costs. These can be overcome with different applications of energy storage systems, integration of new market players, or a combination of storage technologies along with the implementation of new energy policies for storage.

“…For the UK alone, a future renewable energy-dominant energy system requires ~100 to 120 GW/100-200 GWh for short-term storage, ~100 to 130 GW/2-6 TWh for medium-term storage, and 70-80 GW/35-40 TWh for long-term storage [8]. A significant amount of work has attempted to address shortterm energy storage, e.g., lithium-ion and sodium-ion batteries, supercapacitors, and flywheels [9][10][11][12], whereas medium-and long-term energy storage types require less effort. For long-term energy storage, high energy density, low energy losses during storage, and low costs are among the top key performance indicators (KPIs) for technology development.…”

Salt Hydrate Adsorption Material-Based Thermochemical Energy Storage for Space Heating Application: A Review

et al. 2023

Recent years have seen increasing attention to TCES technology owing to its potentially high energy density and suitability for long-duration storage with negligible loss, and it benefits the deployment of future net-zero energy systems. This paper provides a review of salt hydrate adsorption material-based TCES for space heating applications at ~150 °C. The incorporation of salt hydrates into a porous matrix to form composite materials provides the best avenue to overcome some challenges such as mass transport limitation and lower thermal conductivity. Therefore, a systematic classification of the host matrix is given, and the most promising host matrix, MIL-101(Cr)(MOFs), which is especially suitable for loading hygroscopic salt, is screened from the perspective of hydrothermal stability, mechanical strength, and water uptake. Higher salt content clogs pores and, conversely, reduces adsorption performance; thus, a balance between salt content and adsorption/desorption performance should be sought. MgCl2/rGOA is obtained with the highest salt loading of 97.3 wt.%, and the optimal adsorption capacity and energy density of 1.6 g·g−1 and 2225.71 kJ·kg−1, respectively. In general, larger pores approximately 8–10 nm inside the matrix are more favorable for salt dispersion. However, for some salts (MgSO4-based composites), a host matrix with smaller pores (2–3 nm) is beneficial for faster reaction kinetics. Water molecule migration behavior, and the phase transition path on the surface or interior of the composite particles, should be identified in the future. Moreover, it is essential to construct a micromechanical experimental model of the interface.
