Summary

Hydrogen technologies have gained increased attention and interest over the last years due to their potential impact on the decarbonization of several sectors. However, that potential is yet to be transformed into reality and technical and economic challenges still prevent the technologies from having their expected impact. Storage and transportation are among the biggest challenges. Different alternatives are currently being explored, with liquefaction presenting a promising solution, even though it is still an expensive and energy-intensive process. To this end, an assessment of current technologies was conducted to evaluate conventional and emerging technologies for hydrogen liquefaction. Among the conventional alternatives, component optimization, hybridization with renewable energy sources or new cooling technologies, and scaling up conventional energy cycles are considered the best options for improvement of efficiency and cost reduction. Among emerging technologies, caloric systems are still at a low stage of development, with magnetocaloric systems considered the most promising solutions.
