The main challenges of liquid hydrogen (H2) storage as one of the most promising techniques for large-scale transport and long-term storage include its high specific energy consumption (SEC), low exergy efficiency, high total expenses, and boil-off gas losses. This article reviews different approaches to improving H2 liquefaction methods, including the implementation of absorption cooling cycles (ACCs), ejector cooling units, liquid nitrogen/liquid natural gas (LNG)/liquid air cold energy recovery, cascade liquefaction processes, mixed refrigerant systems, integration with other structures, optimization algorithms, combined with renewable energy sources, and the pinch strategy. This review discusses the economic, safety, and environmental aspects of various improvement techniques for H2 liquefaction systems in more detail. Standards and codes for H2 liquefaction technologies are presented, and the current status and future potentials of H2 liquefaction processes are investigated. The cost-efficient H2 liquefaction systems are those with higher production rates (>100 tonne/day), higher efficiency (>40%), lower SEC (<6 kWh/kgLH2), and lower investment costs (1–2 $/kgLH2). Increasing the stages in the conversion of ortho- to para-H2 lowers the SEC and increases the investment costs. Moreover, using low-temperature waste heat from various industries and renewable energy in the ACC for precooling is significantly more efficient than electricity generation in power generation cycles to be utilized in H2 liquefaction cycles. In addition, the substitution of LNG cold recovery for the precooling cycle is associated with the lower SEC and cost compared to its combination with the precooling cycle.

“…A series of assumptions are made to simulate the subsystems involved in the proposed process. These assumptions are the same as the ones made in the literature ,,,, to model similar subsystems: The pressure differences for the heat exchangers and separator are considered insignificant. ,,,, The pressure differences for the reactors in the electro-thermochemical cycle, ammonium bicarbonate production system, and formic acid production cycle are considered negligible. ,, The required electrical power for the hybrid system is supplied by wind turbines and an auxiliary power supply. The wind turbines and auxiliary power supply provide continuous power for the hybrid system. The pinch point temperature of the designed heat exchangers is considered greater than 1 °C. The products associated with this hybrid structure are needed according to the export demands of NL and/or import demands of different regions. The utility water inlet temperature and pressure for cooling purposes are assumed to be 24 °C and 1 bar, respectively.…”

Chemical storage of hydrogen, originated from renewable energy, is one of the most efficient and reliable methods to absorb carbon dioxide (CO 2 ) and easily transport large-scale energy to remote areas. In this study, a novel integration of an electro-thermochemical process with industrial flue gas thermal energy and wind turbines is proposed to absorb CO 2 and store chemically hydrogen in the form of methanol, formic acid, and ammonium bicarbonate. The proposed hybrid structure includes a post-combustion CO 2 capture technology, a copper−chlorine thermochemical process, and several ammonium bicarbonate, formic acid, and methanol production cycles. The proposed configuration produces 2597 kg/h methanol, 5270 kg/h ammonium bicarbonate, and 833.3 kg/h formic acid. The energy and exergy efficiencies of the proposed layout are computed at 63.68 and 66.82%, respectively. The exergy analysis depicts that three processes of electro-thermochemical, methanol production, and post-combustion CO 2 capture have the greatest destructed exergy contributions among other subsections to the amounts of 40.85, 30.16, and 7.97%, respectively. The verification, validation, and sensitivity analyses, along with a multi-objective optimization protocol (i.e., a hybrid neural network and a genetic algorithm), are also used to evaluate the proposed system. The objective functions, decision variables, and constraints for the optimization phase are determined through sensitivity analysis. Several multi-criteria decision evaluation methods are employed to prioritize and choose the optimal point from the Pareto set. The electrical power supplied from the wind turbines as well as the auxiliary power supply, and the energy and exergy efficiencies calculated based on the TOPSIS/LINAMP techniques are 9.90 MW, 89.23, and 67.27%, respectively. In addition, the power consumption, energy, and exergy efficiencies at the optimal operating condition, calculated using the
