Analysis report on the technical difficulties of hydrogen energy storage

What are the challenges and opportunities facing hydrogen storage technologies?

In addition, this paper highlights the key challenges and opportunities facing the development and commercialization of hydrogen storage technologies, including the need for improved materials, enhanced system integration, increased awareness, and acceptance.

What is a comprehensive assessment of hydrogen storage technologies?

This comprehensive assessment offers a current overview of the state-of-the-art in hydrogen storage technologies, outlining both the significant progress made and the pivotal challenges that need attention.

What are the different storage and transportation methods for hydrogen?

Then, the different storage and transportation methods (compressed hydrogen storage, liquid hydrogen, blending hydrogen into natural gas pipelines and ammonia as a large-scale green hydrogen carrier) are analyzed, as well as an evaluation of the challenges and opportunities for large-scale deployment.

What technologies are available for hydrogen storage?

Various technologies are available, including some that have been applied on a large scale for decades, for example, compressed hydrogen gas, liquid hydrogen, blending hydrogen into natural gas pipelines and ammonia for hydrogen storage, as shown in Fig. 3.

What is the economics of hydrogen storage scale?

It is revealed that the economics of scale are proven in terms of hydrogen storage scale. For instance, the unit hydrogen storage cost of CO 2 –methanol which is calculated as 20.4–103.3 €/kgH 2 at the current scale of hydrogen storage can be reduced to 2.2 €/kgH 2 at 300 m 3 /h [86, 87].

What is a major challenge in hydrogen storage?

The critical challenge in hydrogen storage is to achieve convenient, safe, and economical storage of hydrogen. Therefore, storing hydrogen at high pressure can mitigate this challenge to some extent.
