How Hydrogen Storage Works. Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure).
This is where hydrogen could play a pivotal role: Its potential applications in seasonal and diurnal energy storage can offer a buffer for renewables, helping to balance the supply and demand by storing excess energy for later use. Moreover, off-grid energy storage is becoming increasingly important for remote or isolated regions

For the stationary applications, the weight of the storage system that is gravimetric hydrogen density is less of a concern than the volume of the storage system or volumetric hydrogen density. For the on-board applications, on the other hand, both the gravimetric as well as volumetric densities are crucial though volumetric energy density is
Hydrogen, known for its high energy density and clean combustion, contributes to improved combustion efficiency and a reduced environmental impact. Ammonia, on the other hand, contains no carbon atoms, which eliminates the production of carbon dioxide and other harmful greenhouse gases during combustion [9].

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water, electricity, and heat. Hydrogen and fuel cells can play an important role in our national energy strategy, with the potential for use in a broad range of applications, across virtually all sectors—transportation, commercial, industrial, residential, and portable.
Nevertheless, the hydrogen concentration in syngas from gasification may reach values above 60% and further hydrogen addition is barely needed, what limits the energy storage potential [11]. Sewage plants produce poor biogas and its upgrading is relatively expensive.
