Harnessing Coal: A Solution to Storing Hydrogen?

💡Hydrogen is a clean alternative to fossil fuels, but storing it is difficult due to its low boiling point and small size.

🔋Scientists propose using coal as a medium to store hydrogen, creating hydrogen 'batteries' in depleted coal beds.

🌡️The adsorption potential of hydrogen in coal varies depending on coal type and rank.

📚Researchers have conducted experimental work to investigate the feasibility of coalbed-based hydrogen storage.

🌍Developing efficient hydrogen storage methods is crucial for a cleaner and greener energy future.

Why is storing hydrogen difficult?

—Hydrogen has a low boiling point and small size, making it challenging to store. It requires extremely low temperatures or high pressures for storage.

How can coal be used to store hydrogen?

—Coal, particularly coal beds, can adsorb hydrogen gas like a sponge, providing a potential solution for storage. Depleted coal beds could be used as hydrogen 'batteries'.

Does the type of coal affect hydrogen storage?

—Yes, the diffusivity and adsorption potential of hydrogen in coal vary depending on the type and rank of coal. Lower-rank coals may have better storage capabilities.

What is being done to research coalbed-based hydrogen storage?

—Scientists are conducting experimental work to investigate the feasibility and efficiency of storing hydrogen in coal beds. Further research is needed to determine its viability.

Why is finding efficient hydrogen storage methods important?

—Efficient hydrogen storage is crucial for the development of a cleaner and greener energy future, as hydrogen is a promising alternative to fossil fuels.
