🧠 What It Means
High gravimetric density means lighter, more efficient systems.
Crucial for transport applications like FCEVs and aerospace.
A major metric for evaluating new storage technologies.
❗ Key Challenges
Difficult to achieve both high gravimetric and volumetric density.
Advanced materials like metal hydrides can add weight.
Trade-offs between cost, safety, and density remain.
🦁 Muzaffar’s Comment
“The lighter we make hydrogen storage, the closer we get to true mobility.”
🦉 Sameer’s Comment
“Weight matters—a few kilos saved can make or break a car’s efficiency.”
