“…Most often, the liquefaction technology for charging needs to be selected amongst the cycles of Linde-Hampson, Claude, Heylandt and Collins, or a cycle with two expanders. Shmeleva and Arkharov [2] compared different options and concluded that the Claude cycle is optimal for LAES purposes. Thus, the LAES configurations analysed hereafter in Sections 2.2 and 3.2 also resort to the Claude cycle.…”

This contribution elaborates on a futuristic hybrid concept for the multifunctional employment of a liquid air energy storage (LAES) system for combined heat, cold and power production (tri-generation) in a food factory, thereby providing a substantial part of the energy demand for various unit operations and enhancing the round-trip efficiency (RTE) of LAES. A processing line for frozen French fries, with relatively high heating and refrigeration demands, is used as a case study. The total useful energy output per charge/discharge cycle is 61,677 kWh (i.e., 38,295 kWh of electricity, 19,278 kWh of heating, and 4104 kWh of refrigeration). The estimated tri-generation RTE of the studied system reaches 55.63%, which appears to be 1.2 times higher than the RTE of a classical standalone LAES system with the same power input, considered as a baseline. In a broader context, such a performance enhancement by amalgamating food and energy technologies can make cryogenic energy storage a more viable grid balancing option capable of substantially increasing the share of renewables in the energy supply mix.

For many years, there has been great interest in metal-organic frameworks, or MOFs. MOFs are a family of crystalline hybrid organic-inorganic compounds made up of strong coordination interactions connecting metal molecules to organic ligands. Due to their vast specific surface area, structural diversity, and adjustable pore size and functionality, they are highly advantageous in a variety of applications, including hydrogen storage. As a result, MOFs have been thoroughly researched. This study examines the drawbacks of traditional hydrogen storage methods before concentrating on MOFs’ potential as a cutting-edge material to get around these issues. The work also illustrates the benefits of MOFs in enhancing hydrogen adsorption performance by examining the synthesis techniques, functionalization tuning strategies, and their use with metal nanoparticle composites. Simultaneously, the significance of fine-tuning the functionalization and optimizing the performance of MOFs is underscored, and their potential to foster hydrogen-based economic growth is anticipated.

The research community is becoming more interested in liquid air energy storage among the leading innovative technologies for long duration and grid-scale energy storage. Practical Uses of liquid air energy storage are currently somewhat limited, though, mostly due to the intricate design of LAES plants and the poor “roundtrip efficiency” that is the ratio of the energy recovered from the LAES system during the discharge cycle to the total energy input. With so many components already present in the LAES plant, nearly every research project underway adds even more complexity to the mix. The objective of the work that is being presented aims to increase the use of the heat of compression that has been stored during the charging without adding additional complexity. A mixture of water vapour and air, or humidified air, serves as the working fluid in the presented concept. Thermodynamic performance of the proposed discharge configuration is evaluated and compared on a consistent basis with the stand alone LAES system. The results demonstrate significant increase in the roundtrip efficiency.
