“…Combining the above facts with the knowledge that 20 of the last 23 years have been among the hottest on record in the world, it somewhat forces us to seek new solutions in cooling production methods. The search for sustainable solutions is also critical because heat and cooling production consumes 51% of the world's energy demand [3].…”

“…Setting the bed in motion under the influence of gas flowing through it facilitates heat and mass transport processes in the adsorption beds. An attractive option is using moving adsorption beds, as they do not require the input of mechanical energy to improve mass and heat transport [3,36,37]. Due to the ability to improve heat and mass transfer, fluidization has been applied in power boilers and thermochemical energy storage [38][39][40][41].…”

Adsorption technology utilizes low-temperature renewable and waste heat sources for cost-effective and environmentally friendly cooling and water desalination systems. However, the problem with existing adsorption refrigerators is the low COP. This is caused by poor heat and mass transfer in existing packed bed designs. The solution to this problem lies in the use of fluidized bed technology, which enhances heat and mass transfer mechanisms. Various approaches to the construction and operation of adsorption systems with a fluidized bed of adsorbent can be found in the literature; hence, the aim of the work is to analyze the existing applications of a fluidized bed in adsorption refrigerators and other systems utilizing sorption beds. There are many methods for improving the energy efficiency of adsorption refrigerators. However, the literature suggests that fluidized bed systems have the potential to significantly improve the energy efficiency of adsorption cooling and desalination systems. Based on the review, it was concluded that using fluidization technology in adsorption cooling and desalination systems can be beneficial and represents significant potential for future research.

“…Such a scheme would increase the energy and resource efficiencies not only of regional energy systems (including the DH networks) but also of the national energy system (because the transportation of energy could be carried out without relying on the electricity transmission network) while boosting the penetration of VRE. The idea of combining TCES and DH is attractive because a large share of the available infrastructure of the DH system can be adapted to use a reduced metal as fuel [16,17]. DH plants based on solid fuels (fossil and nonfossil) in the Nordic countries typically use fluidized bed (FB) combustors (either bubbling or circulating), which can be retrofitted to process metal powders [18].…”

Thermochemical Energy Storage with Integrated District Heat Production–A Case Study of Sweden

et al. 2023

The implementation of electricity-charged thermochemical energy storage (TCES) using high-temperature solid cycles would benefit the energy system by enabling the absorption of variable renewable energy (VRE) and its conversion into dispatchable heat and power. Using a Swedish case study, this paper presents a process for TCES-integrated district heating (DH) production, assesses its technical suitability, and discusses some practical implications and additional implementation options. The mass and energy flows of a biomass plant retrofitted with an iron-based redox loop are calculated for nine specific scenarios that exemplify its operation under electricity generation mixes that differ with respect to variability and price. In addition, the use of two types of electrolyzers (low-temperature and high-temperature versions) is investigated. The results show that for the Swedish case, the proposed scheme is technically feasible and capable of covering the national DH demand by making use of the existing DH plants, with an estimated process energy efficiency (electricity to heat) of 90%. The results also show that for a retrofit of the entire Swedish DH fleet, the required inventories of iron are approximately 2.8 Mt for the intermediate scenario, which represents 0.3% and 11.0% of the national reserves and annual metallurgical production rates of the national industry, respectively. In addition to the dispatchable heat, the process generates a significant amount of nondispatchable heat, especially for the case that employs low-temperature electrolyzers. This added generation capacity allows the process to cover the heat demand while decreasing the maximum capacity of the charging side computed herein.

“…Sorption-based chemicals are suited to lower-temperature TCES pairs. These have been suggested for domestic hot water and domestic space heating due to their high energy density (when compared with sensible and latent thermal energy storage), and their low charging temperature, as well as their high cycle stability [11,12]. Initially, research in this field focused on the use of pure sorption materials (i.e., molecular sieves) such as zeolites and silica gels and more recently, metal-organic frameworks.…”

Composite thermochemical energy storage (TCES) represents an exciting field of thermal energy storage which could address the issue of seasonal variance in renewable energy supply. However, there are open questions about their performance and the root cause of some observed phenomena. Some researchers have observed the breakdown of particles in their production phase, and in their use. This study seeks to investigate the underlying cause of this breakdown. SEM and EDX analysis have been conducted on MgCl 2 impregnated 13X zeolite composites of differing diameters, as well as LiX zeolite. This was done in order to study the level of impregnation of salt into the zeolite matrix, as well as the effect this impregnation process has on the morphology of the zeolite. Analysis was conducted using ImageJ software to study the effect of the impregnation process on the diameter of the particles. It has been found that a by weight impregnation concentration of magnesium chloride of 11.90% for the LiX zeolite, and 7.59% and 5.26% for the large diameter 13X zeolite and the small diameter 13X zeolite respectively has been achieved. It has been found that the impregnation process significantly affects the morphology of 13X zeolite particles, causing large fissures to form, and eventually resulting in the previously found breakdown of these particles. It has been verified that a primary factor influencing the breakdown of the 13X zeolite particles is the efflorescence and sub-fluorescence phenomena, which leads to a build-up of crystals in the zeolite pores. It has also been found that prolonged impregnation times and the use of high concentration salt solutions in the soaking process can induce significant crystal growth which also leads to the breakdown of these particles. Results demonstrate that LiX zeolite is the optimum host matrix choice in these conditions. These results will allow for the design of more resilient composite TCES particles.
