“…Figure 13 lists common applications of TES in the temperature range between −50 and 400 °C, as well as a measure of the potential of PCMs to provide EE, ER, LS/S, and TM benefits for each of the listed applications. For example, incorporating PCMs in building air‐conditioning systems provides a LS/S benefit and could potentially provide EE and ER benefits depending on system configuration and climate, [ 3 ] but would not provide a TM benefit. Incorporating PCMs into textiles or cooling fabrics worn by humans provides comfort TM and potentially LS/S building loads if worn by enough occupants but is unlikely to provide EE or ER benefits.…”

“…[ 40 ] While this is a cost‐effective TES solution for campus systems and large commercial buildings, there is a need to integrate TES into smaller, modular building systems, as all residential buildings and most commercial building floor space are conditioned by smaller packaged air conditioners and heat pumps. [ 3 ] Additive manufacturing can play a leading role in developing power‐dense, high‐efficiency compact PCM‐integrated heat exchangers for such applications.…”

Phase change materials (PCMs) can enhance the performance of energy systems by time shifting or reducing peak thermal loads. The effectiveness of a PCM is defined by its energy and power density-the total available storage capacity (kWh m −3 ) and how fast it can be accessed (kW m −3 ). These are influenced by both material properties as well as geometry of the energy systems; however, prior efforts have primarily focused on improving material properties, namely, maximizing latent heat of fusion and increasing thermal conductivity. The latter is often at the expense of the former. Advanced manufacturing techniques hold tremendous potential to enable co-optimization of material properties and device geometry, while potentially reducing material waste and manufacturing time. There is an emerging body of research focused on additive manufacturing of PCM composites and devices for thermal energy storage (TES) and thermal management. In this article, the fundamentals and applications of PCMs are reviewed and recent additive manufacturing advances in latent heat TES for both the PCM composite and associated heat exchanger are discussed. A forward-looking perspective on the future and potential of PCM additive manufacturing for TES and thermal management is provided.

“…The speed of phototriggered crystallization dictates the time scale of heat release process, which can be tailored to each application. Lastly, the sustainable operation of the heat storage cycle requires the chemical and photochemical stability of the PCMs, repeatability of the photoswitching and phase transition for hundreds of cycles, and the reasonable cost of materials that will realize the levelized cost of energy storage at $15/kWh level …”

Conspectus Achieving a stable latent heat storage over a wide temperature range and a long period of time as well as accomplishing a controlled heat release from conventional phase change materials have remained prominent challenges in thermal energy control. Because the conventional phase change materials have the fixed phase transition temperatures under the standard ambient pressure, the latent heat storage is only viable at temperatures higher than their melting and crystallization points. Once the latent heat is stored in the liquid phase of materials, it is imperative to maintain the temperature of the system above its crystallization point to prolong the heat storage. Without the continuous energy input or extensive insulation, the crystallization of liquid occurs spontaneously, leading to the loss of latent heat and a short heat storage time. Thus, there exists a critical need to develop methods that enable the control over the phase transition of materials, unrestricted by the temperature of the surroundings. The successful development of such methods and materials in recent years has been viable through the incorporation of molecular switches that respond to external stimuli, notably light, electrochemical bias, and ions, by reversible structural changes. We have discovered novel functional organic material systems that exhibit solid-to-liquid phase transitions controlled by optical and electrical stimulation, along with other research groups. The development and optimization of such materials are enabled by the judicious molecular designs and syntheses. In this Account, we will introduce the cutting-edge design principles of controllable phase change materials that have demonstrated the storage of thermal energy for up to a couple of months without crystallization over a wide temperature range, from subzero to over 100 °C, which addresses the major weakness of conventional phase change materials. In particular, materials that are controlled by solar irradiation and compounds that exhibit substantial gravimetric energy densities are presented, which will guide the further development of functional materials for practical energy storage applications. The controllable heat storage materials will not only recycle the wasted solar thermal energy but also ameliorate massive energy loss in industrial processes. In particular, the waste heat released at temperatures below 100 °C can be effectively absorbed and stored in organic phase change materials, which cannot be easily reclaimed by other energy conversion and storage systems, including thermoelectrics and electrical batteries. This complementary storage method will harness various sources of waste heat and reduce the consumption of fossil fuels by recycling the wasted energy, which will contribute to mitigating climate change.

Energy systems are progressive and revolutionary for their alternative resources, technical developments, demands, effectiveness and environmental effects. The recently published research's goal is to assess and evaluate the systems that are already in operation and those that will be in the future. Energy can be stored as electrical energy such as supercapacitors (SCs) and superconducting magnetic energy storage (SMES) etc., mechanical energy such as pumped hydro energy storage (PHES), compressed air energy storage (CAES) and flywheel energy storage (FES) etc., chemical energy, electrochemical energy such as batteries and fuel cells etc., and thermal energy. Performance of these energy storage systems (ESSs) have been evaluated in terms of energy density, power density, power ratings, capacitance, discharge-time, energy-efficiency, life-time and cycling-times, and costs. Supercapacitors provide highest power density (>10,0000 W/l), while hydrogen fuel cells provide highest energy density (500-3000Wh/l) among other EESs. Batteries also provide high energy density(200-500Wh/l). The energy efficiency is found highest in SMES system (95-98%), and lowest in TES system (30-50%). Moreover, batteries and supercapacitors have the cycle efficiency above 90%. PHES and CAES seem to be the most cost-effective energy storage systems reviewed in this analysis in terms of $/kWh. In addition, power-based capital cost of supercapacitors is lower (100-300$/kW) compared to energy-based capital cost of supercapacitors (300-2000$/kWh). In comparison with power-based capital costs, the energy-based capital cost of batteries is lower, which is 150-400$/kWh for Lead-acid battery, and <300$/kWh for Li-ion battery. This essay may help researchers in choosing the advanced energy storage technologies for relevant purposes.
