“…A complete knowledge of the cryogenic cycle arrangement and its distance from the optimal arrangement is gained using the CCs, GCCs, and heat exchanger networks as the qualitative indexes obtained from pinch analysis in H 2 liquefaction systems. Next, by altering the design and arrangement of the equipment in the refrigeration process, the optimal arrangement is selected. ,,,,, It is possible to target the overall costs of the system, including the operational costs of energy supply and the initial costs of providing network equipment using CC and GCC diagrams. Thus, by changing Δ T min and calculating the cost of the required level for the network and the cost of providing utility services, the system total cost is calculated for each Δ T min , and then, the lowest total cost required for the system as the target point is determined.…”

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.

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
