Analysis and performance assessment of a combined geothermal power-based hydrogen production and liquefaction system [PDF]
International Journal of Hydrogen Energy, 2018 In this paper, the thermodynamic study of a combined geothermal power-based hydrogen generation and liquefaction system is investigated for performance assessment. Because hydrogen is the energy of future, the purpose of this study is to produce hydrogen

Hydrogen liquefaction and liquid hydrogen storage
, 2016 In view of a vast hydrogen infrastructure, very large quantities of hydrogen may be distributed and stored as a liquid at about 20 K (-253°C). Today hydrogen liquefiers are a mature technology for capacities up to 30 tonnes per day and with energy requirements of 30 to 40 MJ per kilogram of liquefied hydrogen, while the World capacity is today around ...

Economics of hydrogen production and liquefaction by geothermal energy
International Journal of Hydrogen Energy, 2012 Seven models are considered for the production and liquefaction of hydrogen by geothermal energy. In these models, we use electrolysis and high-temperature steam electrolysis processes for hydrogen production, a binary power plant for geothermal power ...

Hydrogen liquefaction and storage: Recent progress and perspectives [PDF]
Renewable and Sustainable Energy Reviews, 2023 The global energy sector accounts for ∼75% of total greenhouse gas (GHG) emissions. Low-carbon energy carriers, such as hydrogen, are seen as necessary to enable an energy transition away from the current fossil-derived energy paradigm.

Because of increased activities in cryogenic engineering, liquefaction cycles, in particular hydrogen cycles, are undergoing a more thorough thermodynamic analysis than had been justified previously.

Small-scale liquefaction of hydrogen
International Journal of Hydrogen Energy, 1992Abstract Hydrogen may be stored compactly as a cryogenic liquid at low pressure and temperature, i.e. 20 K at atmospheric pressure. Gaseous hydrogen at normal temperature may be liquefied on a small scale using a cryogenic refrigerator (cryocooler). Stirling refrigerators are well suited to this duty.

Liquefaction of hydrogen by the expansion method
Proceedings of the Physical Society, 1935Descriptions of some experiments to liquefy hydrogen by the expansion method (a) by pure expansion, and (b) by the additional use of the Joule-Thomson effect. The yields are of such an order that it seems promising to build large hydrogen-liquefiers on this principle.

Fundamentals of Hydrogen Liquefaction
1960The selection of a hydrogen liquefaction cycle depends on the use to which the liquefier must be put. In a small laboratory, liquefier safety, reliability, simplicity, and initial cost would most likely be the main items of consideration. On the other hand, if the stress is on low operating cost in a large production operation, careful consideration ...
