The working principle of hydrogen energy storage and energy conversion process

How does a hydrogen storage system work?

The electrolytic cell is the core of the hydrogen storage system, in which electrical energy is converted into heat and chemical water to obtain O 2 and hydrogen. The compressor is used to compress H 2 and store it in the high-pressure gas storage tank [18,19,29]. Fig. 10. Hydrogen storage system.

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.

Can a hydrogen storage system reduce operational costs?

The findings demonstrate that incorporating an energy storage system (ESS) can cut operational costs by 18 %. However, the utilization of a hydrogen storage system can further slash costs, achieving reductions of up to 26 % for energy suppliers and up to 40 % for both energy and reserve suppliers.

How to transport hydrogen from production areas to storage facilities?

Transportation: Transporting hydrogen from hydrogen production areas to storage facilities can be challenging due to its low volumetric energy density. It is crucial to develop practical and affordable transportation systems, like pipes or high-pressure tanks. 8.

Why do we need a safe and reliable hydrogen storage method?

Frequent cycling process may lead to the degradation of hydrogen storage, therefore safe and reliable storage is pivotal in maximizing hydrogen energy. Although, hydrogen is clean energy the methods employed for production and storage of hydrogen are not environmentally friendly.

Why do we need hydrogen as an energy carrier?

The technology and infrastructure for hydrogen production and storage demand more advancements when compared to conventional technologies and infrastructure. The need for hydrogen as an energy carrier is sharply increasing due to its potential as an alternative to fossil fuels.
