“…The most widely used adsorbate-adsorbent is silica gel/water and reaches T Evap of up to 5 • C [15,[143][144][145]. Systems with activated carbon/methanol have also been evaluated, but the COP and the T Gen increase with respect to silica gel/water [16,[146][147][148][149]. In comparison, ABS equipment has a COP between 0.7-1.8 and a T Gen between 80-220 • C [13,109,150,151].…”

The trend to reduce CO2 emissions in cooling processes has made it possible to increase the alternatives for integrating solar energy with thermal equipment whose viability depends on its adaptation to polygeneration schemes. Despite the enormous potential offered by the industry for cooling and heating processes, solar cooling technologies (SCT) have been explored in a limited way in the industrial sector. This work discusses the potential applications of industrial SCTs and classifies hybrid polygeneration schemes based on supplying cold, heat, electricity, and desalination of water; summarizes the leading SCTs, and details the main indicators of polygeneration configurations in terms of reductions on primary energy consumption and payback times. To achieve an energy transition in refrigeration processes, the scenarios with the most significant potential are: the food manufacturing industry (water immersion and crystallization processes), the beverage industry (fermentation and storage processes), and the mining industry (underground air conditioning).

The storage of hydrogen by adsorbent materials has been addressed by several researchers. These materials can serve as a reservoir of hydrogen at a very lower temperature and the emptying operation for fuel cells is simply heating the adsorbent bed. However, in order to maximize the ability of the adsorbent materials to meet the instantaneous hydrogen demand, adequate knowledge of desorbed hydrogen flow rate (DHR) must be investigated. The objective of this study is to model the control of the DHR induced by heating. The results show that the excess of hydrogen stored in the adsorbent material can be completely released at room temperature and the DHR increases with temperature. A solution is proposed for stabilizing the DHR, which consists in controlling the fuel cell supply section and, consequently, the power to be produced.
