Solvents that can store hydrogen

What are the different types of hydrogen storage solutions?

Crucially, the development of compact, lightweight, safe, and cost-effective storage solutions is vital for realizing a hydrogen economy. Various storage methods, including compressed gas, liquefied hydrogen, cryo-compressed storage, underground storage, and solid-state storage (material-based), each present unique advantages and challenges.

What are chemical methods of hydrogen storage?

Chemical methods of hydrogen storage (also called materials based hydrogen storage) are based on the interaction of hydrogen with the storage media (i.e., hydrogen storage materials) as opposed to physical methods of hydrogen storage in which there is no interaction between hydrogen and the storage media.

Is liquid hydrogen storage a good option?

Currently, liquid hydrogen storage is only attractive for short-term storage (i.e., space applications) due to aforementioned limitations. Cryo-compressed hydrogen storage is based on storing hydrogen at high pressures and cryogenic temperatures (i.e., <77 K).

Which chemical hydrogen storage materials are most promising?

The most promising and well-studied chemical hydrogen storage materials are NaBH 4 [ 85 ], AlH 3 [ 86 ], ammonia-borane (NH 3 · BH 3 or simply AB) [ 87 ], and liquid organic hydrogen carriers such as cyclohexane-benzene [ 88, 89 ]. These materials will be discussed in more detail in the following sections.

What are materials based hydrogen storage?

Among the materials-based storage, liquid organic hydrogen carriers and metal hydrides are two hydrogen storage reliant on materials technologies that offer exciting qualities, making them suitable for certain applications, even in storage at a large scale.

Which LOHC is best for hydrogen storage?

Methyl cyclohexane, N-ethylcarbazole (NEC), and toluene , are considered highly promising as LOHCs for hydrogen storage, with typical storage densities ranging from 5–6 wt%, and use organic compounds to safely store hydrogen through covalent bonds and enable efficient hydrogen release .
