Can large-scale hydrogen storage in porous media enable a global hydrogen economy?

Expectations for energy storage are high but large-scale underground hydrogen storage in porous media (UHSP) remains largely untested. This article identifies and discusses the scientific challenges of hydrogen storage in porous media for safe and efficient large-scale energy storage to enable a global hydrogen economy.

Are all hydrogen storage technologies suitable for long-term storage?

However, not all hydrogen storage technologies are suitable for long-term storage. Long-term and efficient storage of hydrogen energy is also one of the key issues in the development of hydrogen energy on a large scale and one of the constraints that limit the high price of hydrogen energy.

Why is long-term storage of hydrogen important?

Long-term and efficient storage of hydrogen energy is also one of the key issues in the development of hydrogen energy on a large scale and one of the constraints that limit the high price of hydrogen energy. Therefore, long-term storage of hydrogen in a safe and stable form is a prerequisite.

Is hydrogen stored on a large scale?

Previous work related to the storage of hydrogen on a large scale is relatively scarce. Most of this work focuses on underground storage, with a few exceptions.

Is hydrogen a long-term energy storage solution?

Electrical energy storage for the grid: a battery of choices Hydrogen as a long-term large-scale energy storage solution to support renewables Electrical integration of renewable energy into stand-alone power supplies incorporating hydrogen storage

Can a large-capacity hydrogen storage system meet the demand for energy storage?

For instance, if the portion of electricity with rapid fluctuations and the user’s peak load are relatively small, a larger-capacity CB could serve as the base load for energy storage, while a smaller-capacity hydrogen storage system could meet the demand for rapid-response energy storage.
