Hydrogen Storage Solutions

Application required energy density, safety requirements, and cost all influence the selection of hydrogen storage options. A key element of the hydrogen economy is hydrogen storage. Hydrogen must always be stored at high pressure and low temperature. It is also a solid material due to its low density and high flammability.

There are various hydrogen storage options available, and each one has its own special set of benefits and drawbacks. In this post, we’ll go over a variety of hydrogen storage options along with their features, traits, and uses.

  1. Compressed Hydrogen Storage: The most popular and widely utilized method for storing hydrogen is compressed hydrogen storage. This process involves compressing and storing hydrogen gas in high-pressure containers. Metal or composite materials may be used to create the tanks. Storage of compressed hydrogen is appropriate for stationary uses including refueling stations, standby power, and industrial processes. Because tanks are hefty and take up a lot of room, their usage in mobile applications is constrained.
  2. Liquid Hydrogen Storage: In order to store liquid hydrogen, hydrogen gas must first be cooled to its boiling point (-253°C), following which it is placed in insulated containers. Comparing compressed hydrogen storage to liquid hydrogen storage, the former offers a higher energy density. Liquid hydrogen storage is only appropriate for specific niche applications like high-performance cars because of its complexity and high expense.
  3. Metal Hydride Storage: Metal alloys that have the ability to both absorb and release hydrogen gas are used to store metal hydrides. The metal alloys are produced using light metals such as aluminum, titanium, or magnesium. Metal hydride storage is advantageous for safety and low operating pressure in addition to its vast storage capacity.
  4. Chemical Hydrogen Storage: Utilizing chemical substances that, when activated, can release hydrogen gas is known as chemical hydrogen storage. The substances include formic acid, ammonia borane, and sodium borohydride, and they can be either organic or inorganic. The great storage capacity, low-pressure operation, and portability of chemical hydrogen storage are benefits. Small fuel cells, backup power systems, and portable electronics can all benefit from chemical hydrogen storage.

Hydrogen storage has been one of the major technical challenges in the extensively of hydrogen as a fuel source. Some of the key hydrogen storage problems includes:

  1. Low energy density: Hydrogen has a lower energy density per unit volume when compared to common fuels like gasoline and diesel. A larger volume of hydrogen is required to hold the same amount of energy as with fossil fuels.
  2. Storage at high pressures: Hydrogen needs to be compressed to extremely high pressures in order to achieve the required energy density for practical use. This presents a safety concern, as the high pressure can lead to leaks and explosions.
  3. Cryogenic storage: Cooling hydrogen to extremely low temperatures to turn it into a liquid is another way to store it.
  4. Material compatibility: Hydrogen can cause embrittlement and corrosion in some materials, so storage tanks and pipelines must be made from materials that are compatible with hydrogen.
  5. Cost: As compared to other fuels, the cost of storing hydrogen is still expensive. The price of cryogenic storage, high-pressure tanks, and materials compatible with hydrogen can raise the overall cost of hydrogen storage.
