A comparison of technical efficiencies of the energy storage in Table 2 shows that electrochemical storage options have greater efficiencies than hydrogen storage, although hydrogen storage has greater specific energy. The low hydrogen storage efficiency would imply significant energy losses as compared to other technologies.
Conversely, hydrogen storage boasts higher energy density (500–3000 Wh/L) but lower round-trip efficiency (30–50 %) compared to batteries. Improving the efficiency of hydrogen storage would enhance its viability for long-term electricity storage, minimizing energy loss. Energy transfer for end-use is also a critical aspect of the production chain.
This makes it more difficult and expensive to store and transport hydrogen for use as a fuel (Rivard et al. 2019). There are several storage methods that can be used to address this challenge, such as compressed gas storage, liquid hydrogen storage, and solid-state storage.
However, Marchenko & Solomin posit that both hydrogen and electricity storage could complement each other in the future where electricity storage provides short-term (Seconds-Minutes) and Medium-term (Minutes-hours) energy storage while hydrogen provides long-term storage (hours-months). Fig. 7.
Further, developing in-situ synthesis techniques for enhancing micropore geometry will be the key to finding more efficient hydrogen storage systems. Also, it is necessary to study how dissociated hydrogen atoms are transported onto receptor surfaces.
They can be classified according to the energy form of the storage systems, such as mechanical, electrochemical, chemical energy, electrical, and thermal. Hydrogen can be stored through liquefaction, compression, and chemical (i.e., NH3, formic acid, methanol etc.) and physical storage media.
