Introduction
Sorption materials are solids that can absorb or adsorb hydrogen, often used for storage or purification.

🧠 What It Means
Absorption: hydrogen enters the material (e.g. metal hydrides).
Adsorption: hydrogen sticks to the surface (e.g. activated carbon).
Used in hydrogen tanks, filters, and sensors.
❗ Key Challenges
Must balance storage capacity, release rate, and weight.
Some require high pressure or temperature swings.
Degradation after multiple cycles can limit lifespan.
Muzaffar’s Comment
“Sorption materials are like sponges for hydrogen — only smarter and much stronger.”
🦉 Sameer’s Comment
“They hold hydrogen when we don’t need it — and release it when we do.”
