Hydrogen as an energy storage path

Why is hydrogen a potential energy storage medium?

Hydrogen offers a potential energy storage medium because of its versatility. The gas can be produced by electrolysis of water, making it easy to integrate with electricity generation. Once made, the hydrogen can be burned in thermal power plants to generate electricity again or it can be used as the energy source for fuel cells.

How can hydrogen energy be stored?

Stored hydrogen in the form of compressed gas can be distributed in dedicated pipelines over a long distance, while the liquid stored hydrogen can be transported in tankers by rail, ship or road to the urban area. Unlike other mentioned energy storages above, the hydrogen energy can be produced close to the point of use . Samuel C. Johnson, ...

Can hydrogen be stored as a fuel?

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.

What are the benefits of hydrogen storage?

4. Distribution and storage flexibility: hydrogen can be stored and transported in a variety of forms, including compressed gas, liquid, and solid form . This allows for greater flexibility in the distribution and storage of energy, which can enhance energy security by reducing the vulnerability of the energy system to disruptions.

Can hydrogen be used for electricity storage?

During the discharge phase, the stored hydrogen is either used in fuel cell or burnt directly to produce electricity. One major drawback in using hydrogen for electricity storage is the substantial energy losses during a single cycle .

Is hydrogen a viable energy storage method?

Although hydrogen production is a versatile energy storage method, offering clean and efficient electricity generation as well as scalability and a compact design, many challenges still face this technology.
