“…Thermodynamic flowsheet simulations using the software ChemCAD ( [18]) based on comparable boundary conditions (e.g. realistic turbomachine efficiencies and pinch temperatures) are combined with an equipment based cost estimation [19]. Equipment cost are then converted to installed cost using an installation factor for assembling the equipment, piping, instrumentation etc.…”

With continuously falling cost of renewable power generation and ambitious decarbonization targets, renewable sources are about to rival fossil fuels for energy supply. For a high share of fluctuating renewable generation, large-scale energy storage is likely to be required. In addition to selling electricity, the reliable supply of heat and cold is a further interesting revenue pool, which makes hybrid storage technologies an interesting option. The main feature of hybrid energy storageas defined here-is to offer charging and especially discharging in different forms of energy by combining different charging, discharging and storage devices. They can address various demands (e.g. electricity and cold) simultaneously. Two hybrid storages, pumped thermal energy storage (PTES) and power-to-heat-to-x (x: heat and/or electricity) energy storage (PHXES), are investigated based on a technoeconomic analysis within this work. Both hybrid storage technologies are charged with electricity and can supply heat and electricity during discharging. They are implemented into a simplified energy system model of a prototype city in the earth's sunbelt in the year 2030 to find a cost-optimal configuration. Different cases are evaluated: a power-to-power case (P2P), where only an electric demand must be addressed and a power-topower-and-cooling (P2P&C) case, where the electric demand from the P2P case is divided into a residual electric demand and a cooling demand. For both cases, a natural gas-based benchmark scenario and a decarbonized, renewable-based scenario including the hybrid energy storage technologies are calculated. Both, total expenditures and CO2 emissions are lower in the P2P&C scenarios compared to P2P scenarios. PHXES plays a major role in both cases. PTES is part of the costoptimal solution in the P2P&C decarb scenario, only if its specific cost are further decreased.

“…The cost function for thermal storages in [19] has been updated and is now based on a pressure vessel calculation. The cost of each thermal storage is calculated based on the corresponding process conditions (upper temperature, lower temperature, pressure) coming from the flowsheet.…”

“…In hybrid ESS, the improved cycle efficiency and optimal performance is achieved by coordinating the qualities of the available ESS [ 139 ]. The purpose of all the hybrid ESS is to merge high energy density with high power densities in devices, to achieve power and energy rating characteristics [ 140 ].…”

This paper reviews energy storage systems, in general, and for specific applications in low-cost micro-energy harvesting (MEH) systems, low-cost microelectronic devices, and wireless sensor networks (WSNs). With the development of electronic gadgets, low-cost microelectronic devices and WSNs, the need for an efficient, light and reliable energy storage device is increased. The current energy storage systems (ESS) have the disadvantages of self-discharging, energy density, life cycles, and cost. The ambient energy resources are the best option as an energy source, but the main challenge in harvesting energy from ambient sources is the instability of the source of energy. Due to the explosion of lithium batteries in many cases, and the pros associated with them, the design of an efficient device, which is more reliable and efficient than conventional batteries, is important. This review paper focused on the issues of the reliability and performance of electrical ESS, and, especially, discussed the technical challenges and suggested solutions for ESS (batteries, supercapacitors, and for a hybrid combination of supercapacitors and batteries) in detail. Nowadays, the main market of batteries is WSNs, but in the last decade, the world’s attention has turned toward supercapacitors as a good alternative of batteries. The main advantages of supercapacitors are their light weight, volume, greater life cycle, turbo charging/discharging, high energy density and power density, low cost, easy maintenance, and no pollution. This study reviews supercapacitors as a better alternative of batteries in low-cost electronic devices, WSNs, and MEH systems.

“…The general concept of PTES has been discussed under a variety of names in the literature, including "Carnot battery," which can also consider direct resistive heating to charge the hot storage (Walter et al 2020). In common with many thermo-mechanical systems, the energy and power capacities of PTES can be decoupled, and the marginal cost of additional energy storage is potentially very low.…”

NREL), envisions how, over the next few decades, solar could come to power 40% or more of U.S. electricity demand, dramatically accelerating the decarbonization of buildings, transportation, and industry.Through state-of-the-art modeling, the Solar Futures Study is the most comprehensive review to date of the potential role of solar in decarbonizing the U.S. electric grid and broader energy system. However, not all the detailed analysis that informed the Solar Futures Study could be included within its pages. This further analysis is collected in additional National Renewable Energy Laboratory reports, each dedicated to a different technology or socioeconomic concern.This report, The Role of Concentrating Solar-Thermal Technologies in a Decarbonized U.S. Grid, focuses on a particular technology area that could contribute to decarbonization.
