Technologies for Hydrogen Fuel Cell Storage

• One element of the hydrogen economy that is
  essential is hydrogen storage. Hydrogen must be
  kept in a solid state, under high pressure, or at
  low temperatures due to its low density and great
  flammability.

• There are several hydrogen storage options
  available, and each has benefits and drawbacks of
  its own. The many varieties of hydrogen storage
  solutions, together with their attributes and
  uses.
• Compressed Hydrogen Storage The most popular and
  extensively utilized technique for storing
  hydrogen is compressed gas storage. Compressed
  hydrogen gas is kept in high-pressure tanks using
  this technique. Composite or metal materials can
  be used to make the tanks. Greater store capacity
  is offered by higher pressures, which fall
  between 350 and 700 bar in the storage pressure
  range. Stationary applications such as refueling
  stations, industrial operations, and backup power
  can benefit from compressed hydrogen storage
  technology. Its usage in mobile applications is
  limited, nevertheless, by the tanks' weight and
  space requirements.

• Liquid Hydrogen Storage When hydrogen gas is
  stored in insulated tanks, it is first cooled to
  its boiling point (-253?C) to liquefy it. When
  comparing compressed and liquid hydrogen storage,
  the former offers a higher energy density. The
  tanks must be tightly insulated to prevent
  boil-off and venting, though, as it demands
  cryogenic temperatures.
• Metal Hydride Storage Metal alloys with the
  ability to absorb and release hydrogen gas are
  used in metal hydride storage. Aluminum,
  titanium, or magnesium are common lightweight
  metals used to make metal alloys. Metal hydride
  storage has several benefits, including as low
  operating pressure, safety, and large storage
  capacity. The alloys' high cost and requirement
  for high temperatures to liberate hydrogen are
  drawbacks. Backup power systems, tiny fuel cells,
  and portable electronics are good uses for metal
  hydride storage.
• Chemical Hydrogen Storage Chemical substances
  that can release hydrogen gas when activated are
  used in chemical hydrogen storage. Formic acid,
  ammonia borane, and sodium borohydride are among
  the chemicals, which can be either organic or
  inorganic. High storage capacity, low operating
  pressure, and portability are benefits of
  chemical hydrogen storage. The compounds'
  drawbacks are that they are costly, produce
  byproducts, and need a catalyst to release
  hydrogen. Portable electronics, tiny fuel cells,
  and backup power systems can all benefit from
  chemical hydrogen storage.
• Within the hydrogen supply chain, storage is an
  essential component. In off-peak hours, it
  permits the production of hydrogen and its
  delivery to the site of consumption. Applications
  vary in terms of energy density, safety, and cost
  requirements, which influence the choice of
  hydrogen storage technologies. The goal of
  ongoing research and development is to lower the
  cost of hydrogen storage while increasing its
  efficiency.
