Principle of liquid hydrogen energy storage

How can hydrogen be stored?

Hydrogen can be stored physically as either a gas or a liquid. Storage as a gas requires high-pressure tanks (350–700 bar), while storage as a liquid requires cryogenic temperatures due to hydrogen's boiling point of −252.8°C at one atmosphere pressure.

This publication is licensed under CC-BY-NC-ND 4.0. The main challenges of liquid hydrogen (H 2) 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.

Why is liquid hydrogen important?

Among these, liquid hydrogen, due to its high energy density, ambient storage pressure, high hydrogen purity (no contamination risks), and mature technology (stationary liquid hydrogen storage), is suitable for the transport of large-volumes of hydrogen over long distances and has gained increased attention in recent years.

Why do we need hydrogen storage & transportation systems?

The massive adoption of hydrogen demands a broad range of hydrogen storage and transportation systems. Liquid its high gravimetric and volumetric energy densities and hydrogen purity. The very low characteristics of liquid hydrogen, which should be appropriately and sufficiently managed.

What is a hydrogen storage solution?

Efficient hydrogen storage solution for sustainable energy transportation and storage. Enables safe and cost-effective hydrogen transportation and distribution networks. Promotes renewable energy integration through versatile and scalable storage capabilities.

What is mobile hydrogen storage?

Mobile storage is used to transport liquid hydrogen from one place to another via road, railway or maritime. When road transport is adopted, liquid hydrogen needs to be stored on board of road tankers (contained in the double walled tank).
