“…The installation flexibility, compactness, and global availability, are some of the advantages of battery energy storage systems. 8 It is good to mention that battery and supercapacitor energy storage systems are still used for short-term storage. Electric vehicles' powering and electronic devices have also been made possible by battery and supercapacitor storage systems.…”

In this study, the benefits and challenges of existing energy storage systems are presented. The environmental threats and the apparent unreliability of fossil fuel energy sources necessitate the need for alternative sources of electrical power. Energy storage has been sourced from mechanical, electrical, thermal, chemical, and electrochemical systems. Perhaps, an electrochemical energy storage system, is a better option toward achieving a net zero carbon‐dioxide emission by 2050. Energy storage sources, such as: batteries and supercapacitors, can be reliably fabricated from the hybrid of polymers and two‐dimensional materials for electric vehicles, aviation, and grid load balancing applications. The performances of lithium‐ion batteries are yet to meet the requirements for high‐duty machines and devices. Graphite, the anode of lithium‐ion batteries, suffers from low capacity and high volume‐expansion, resulting in cracking and fracture of the electrodes. Herein, based on evidence from literature, this study suggests substituting graphite with polymer nanocomposite or metal‐oxide nanocomposites such as: conducting polymers, copper oxide, and graphene. This approach, giving attention to these materials' excellent electrochemical, thermal, electrical, mechanical, and redox properties, offers possible ways to overcome the limited limitations confronting lithium‐ion battery technology.

“…[ 2 ] Although PHS is an interesting technology with widespread benefits, further successful deployment of PHS at large scale is questionable, as projects require long lead times, need to fulfill specific geographic requirements, and can face backlash from community stakeholders due to significant local environmental impact. [ 3 ] As an alternative to PHS a wide variety of mechanical, chemical, thermal, and electrical energy storage technologies are currently being considered, comprehensive overviews of which are provided by Rahman et al [ 4 ] and Benato and Stoppato.

ZeoPTES: Zeotropic Pumped Thermal Energy Storage with an Ammonia–Water Mixture as Working Fluid

The rapid rise of renewable energy production necessitates the development of large‐scale electricity storage systems. Pumped thermal energy storage (PTES), where electricity is stored in hot and cold storage units, has recently garnered a lot of interest. Previously proposed PTES systems rely on pure fluids as working fluids in Brayton‐ or Rankine‐based power cycles. Herein, ZeoPTES, a PTES system using a zeotropic mixture of ammonia and water as working fluid, is introduced. The mixture exhibits nonisothermal evaporation and condensation, which allows utilization of industrially available sensible storage units, like water or molten salt, to store the thermal energy from these phase changes. A simulation using the REFPROP 10.0 database is written to analyze the cycle. Eight parameters are identified as having an effect on system round‐trip efficiency and 30 000 simulations with random values for these parameters are run to identify the impact of all. Although efficient compressors and expanders are necessary to reach a high power‐to‐power round‐trip efficiency, the largest system‐wide losses arise from entropy generation and thermal stream mismatch in the cold and hot side heat exchangers. Using state‐of‐the‐art microchannel heat exchangers with extremely low pinch points allows for round‐trip efficiencies in excess of 70%.

“…This is significant because it can increase grid stability, improve the efficiency of energy systems, enhance penetration of renewable energy resources, conserve fossil energy resources, and reduce the environmental impact of energy generation. 6,7 Because of the progressive fall in the costs of wind turbines, solar PV, and electrical energy storage (EES), as well as the tremendous advancements in technological development, there is a huge potential that favors the deployment of these technologies in standalone and grid-connected systems. This potential has to be accompanied by an economic analysis of hybrid systems based on PV-wind and EES.…”

This paper presents a detailed analysis of the levelized cost of electricity (LCOE) for a real photovoltaic(PV)‐wind‐battery system installed in a remote area in Morocco. Besides the evaluation of the existing autonomous system, different scenarios are discussed. A techno‐economic evaluation of a PV‐battery system is carried out. Additionally, in order to enrich the discussion, the case of possible connection to the national grid, either in a medium‐ or low‐voltage level is considered. Costs were analyzed using on‐site collected data of energy production and initial (realistic) costs of the different components of the power plant with various discount and degradation rates. In contrast to the grid‐connected mode where all the available energy could be exploited, the detailed analysis shows that the LCOE is affected by the energy management strategy (droop control) in the standalone mode where a part of the energy cannot be used. Furthermore, the degradation rate, the discount rate, and the battery lifetime affect the LCOE. The results show that the LCOE for the PV‐wind‐battery system is optimal compared to the PV‐battery system under different system designs, especially for the low voltage grid‐connection where the grid parity could be achieved.
