Solid-state hydrogen storage technology and the comprehensive comparison of energy density between various hydrogen storage methods. For LSHS materials with intrinsic high energy density, the feasible hydrogen release approaches mainly include thermolysis (via heating) and hydrolysis (via reacting with water).
That''s what the Department of Energy (DOE) concluded when comparing the operation and maintenance (O&M) costs of different hydrogen storage technologies. 12 They pegged metal hydride storage at 0.02 $/kWh versus compressed gas and liquid hydrogen at 0.04 $/kWh and 0.06 $/kWh. Energy density is another essential factor to
The cryogenic liquid hydrogen storage has a relatively high hydrogen storage density but the liquefication process may consume nearly 30% of the stored energy. Also, the liquid hydrogen storage requires special insulated containers, which are generally costly and not suitable for vehicle on-board applications.
The key difficulties for hydrogen storage materials are hydrogen storage density, dehydrogenation temperature, and dehydrogenation kinetics. In this chapter,

The production, storage and transportation of ammonia are industrially standardized. However, the ammonia synthesis process on the exporter side is even more energy-intensive than hydrogen liquefaction. The ammonia cracking process on the importer side consumes additional energy equivalent to ~20% LHV of hydrogen.

Hydrogen can be stored in compressed, liquified, and solid-state, as mentioned in Fig. 4.
