Cryogenic tanks show huge potential in storing hydrogen; research still going on to reduce inefficiencies associated with this storage method.
Here’s an article posted in PV Magazine.
According to the article,
- Cryogenic fuel tanks maintain temperatures below -253°C to transport hydrogen as a liquid, addressing the safety and storage efficiency issues of high-pressure gas-based storage methods.
- The energy required to cool hydrogen to a cryogenic liquid state is approximately 35% of its total energy, making it a promising storage solution.
- Cryogenic tanks offer a potential breakthrough in hydrogen storage, paving the way for safer and more efficient utilization of this clean energy source.
Although the technology of cryogenic hydrogen storage seems promising, it is also not entirely advantageous to implement at the moment.
Here are key points to note regarding the disadvantages of cryogenic hydrogen storage:

- Efficiency: The efficiency of liquid hydrogen storage is estimated at about 53%, meaning that a substantial portion of energy is lost during the liquefaction process and subsequent storage. This inefficiency makes cryogenic storage energetically expensive, particularly when compared to other methods.
- Capital and Operational Costs: The capital costs for cryogenic storage tanks can range from $30 to $50 per kilogram of hydrogen stored, in comparison to $3.00 to $7.00 per kilogram of hydrogen stored using compressed gas storage or $1.50 to $3.00 per kilogram using LOHCs.
These disadvantages, on the other hand however, show only the yet undiscovered potential of this technology, which in turn can be a significant breakthrough for the decarbonisation mission.
