“…Thermal storage systems can be classified into different categories according to their range of working temperature, storage mechanism, nature of circulation, and duration of storage period. [24][25][26][27] 1.1.1 | Based on their operating temperature TES systems are categorized by their operating temperatures such as low-, medium-, and high-temperature TES systems. Storage systems operating under the range of 20 C to 100 C are considered to be a low-temperature storage systems and between 100 C and 200 C are considered to be a medium-temperature storage systems, whereas the systems operating beyond the temperature of 250 C are called high-temperature thermal storage systems.…”

Summary Because of the unstable and intermittent nature of solar energy availability, a thermal energy storage system is required to integrate with the collectors to store thermal energy and retrieve it whenever it is required. Thermal energy storage not only eliminates the discrepancy between energy supply and demand but also increases the performance and reliability of energy systems and plays a crucial role in energy conservation. Under this paper, different thermal energy storage methods, heat transfer enhancement techniques, storage materials, heat transfer fluids, and geometrical configurations are discussed. A comparative assessment of various thermal energy storage methods is also presented. Sensible heat storage involves storing thermal energy within the storage medium by increasing temperature without undergoing any phase transformation, whereas latent heat storage involves storing thermal energy within the material during the transition phase. Combined thermal energy storage is the novel approach to store thermal energy by combining both sensible and latent storage. Based on the literature review, it was found that most of the researchers carried out their work on sensible and latent storage systems with the different storage media and heat transfer fluids. Limited work on a combined sensible‐latent heat thermal energy storage system with different storage materials and heat transfer fluids was carried out so far. Further, combined sensible and latent heat storage systems are reported to have a promising approach, as it reduces the cost and increases the energy storage with a stabilized outflow of temperature from the system. The studies discussed and presented in this paper may be helpful to carry out further research in this area.

“…In both cases, the costs are based on a reported depth of discharge [30]. Other sources report lithium-ion costs of 1200-4000 $/kW [23], [31], [32], [25], [33]. Based on cost and shipment volumes for Li-ion batteries between 1997 and 2003, EPRI calculated a learning rate of 30% [30].…”

“…More recent analysis report a similar range for compressed air storage: 0.10 EUR/kWh in porous rock, 1.01 EUR/kWh in solution-mined salt caverns, 9.71 EUR/kWh in dry-mined salt caverns, 9.71 EUR/kWh in abandoned mines, and 29.55 EUR/kWh in rock caverns from excavation [55]. Overall cost estimates accounting for all types of CAES facilities range from 400 -800 $/kW [56] [23] [31], [32], [25], [33], 500 -1500 $/kW [22], 400-1000 $/kW [24], 910 EUR/kW [57], and 1075 $/kW [41] . Costs in the range of 325 -975 $/kW for gas CAES and 350 -1050 $/kW for hydrogen CAES are assumed in this analysis.…”

The role of electricity storage and hydrogen technologies in enabling global low-carbon energy transitions

Previous studies have noted the importance of electricity storage and hydrogen technologies for enabling large-scale variable renewable energy (VRE) deployment in long-term climate change mitigation scenarios. However, global studies, which typically use integrated assessment models, assume a fixed cost trajectory for storage and hydrogen technologies; thereby ignoring the sensitivity of VRE deployment and/or mitigation costs to uncertainties in future storage and hydrogen technology costs. Yet there is vast uncertainty in the future costs of these technologies, as reflected in the range of projected costs in the literature. This study uses the integrated assessment model, MESSAGE, to explore the implications of future storage and hydrogen technology costs for low-carbon energy transitions across the reported range of projected technology costs.Techno-economic representations of electricity storage and hydrogen technologies, including utility-scale batteries, pumped hydro storage (PHS), compressed air energy storage (CAES), and hydrogen electrolysis, are introduced to MESSAGE and scenarios are used to assess the sensitivity of long-term VRE deployment and mitigation costs across the range of projected technology costs. The results demonstrate that large-scale deployment of electricity storage technologies only occurs when techno-economic assumptions are optimistic. Although pessimistic storage and hydrogen costs reduce the deployment of these technologies, large VRE shares are supported in carbon-constrained futures by the deployment of other low-carbon flexible technologies, such as hydrogen combustion turbines and concentrating solar power with thermal storage. However, the cost of the required energy transition is larger. In the absence of carbon policy, pessimistic hydrogen and storage costs significantly decrease VRE deployment while increasing coal-based electricity generation. Thus, R&D investments that lower the costs of storage and hydrogen technologies are important for reducing emissions in the absence of climate policy and for reducing mitigation costs in the presence of climate policy.

This largescale deployment has been motivated by a number of drivers, including government subsidies, rapidly declining investment costs, energy security concerns, and growing global consensus around climate change risks [3] [4]. Future scenarios of the global energy system suggest an even larger role for renewable energy over the next century, particularly if climate policy is introduced....

“…Primary energy use and the emission of CO2 are most significant during battery manufacturing, since significant SΟx and NOx emissions arise in the extraction and refining of raw materials [60]. According to [63], [57] and [62], the most representative key parameters for the energy assessment of storage systems, which in turn can be coupled with representative environmental indicators are the following, i.e. i) "Technical maturity and specific energy", ii) "Stored energy and round-trip efficiency", iii) "Life time and cycle life" and iv) "Power rating and discharge time".…”

During the last years a variety of numerical tools and algorithms have been developed aiming at quantifying and measuring the environmental impact of multiple types of energy systems, as those based on Renewable Energy Sources. Plenty of studies have proposed the use of a Life Cycle Assessment methodology, to determine the environmental impact of renewable installations when coupled with storage solutions, based on a pre-selected repository of Key Performance Indicators. The main scope of this paper is to propose a limited number of best fitting, and at the same time easily adaptable to various configurations, list of KPIs for the case of renewable energy systems. This is done by capitalizing on the environmental and energy performance KPIs tracked in the open literature (e.g. "Global Warming Potential", "Energy Payback Time", "Battery Total Degradation", "Energy Stored on Invested", "Cumulative Energy Demand") and/or other proposing new simple, scalable and adaptable ones, (e.g. "Embodied Energy for Infrastructure of Materials and for the building system", "Life Cycle CO2 Emissions", "Reduction of the Direct CO2 emissions", "Avoided CO2 Emissions", "CO2 equivalent Payback Time"). Moreover, the proposed KPIs are distributed according to the individual phases of the entire life-cycle of a related component of a renewable energy system, each time the environmental impact refers to, i.e. manufacturing, operational and end-of-life. Apart from that, the current paper presents a necessary base grounded approach, which can be followed for a holistic approach in environmental point of view of renewable-based technologies, by addressing the potential competing interests of the relevant stakeholders (e.g. profit for the market operator in contrast to low-cost services for the consumer). All in all, the scalar quantification of the environmental impact of multiple energy systems, through a list of proposed assessment criteria, being evaluated in terms of the selected repository of KPIs, enables the comparison on a fair basis of the available energy systems, irrespective if they are fossil-fuel or RES based ones. As a typical example, a simple standard model of a photovoltaic integrated with an electric battery is selected, for which indicative indicators are provided.
