What are the Challenges in Catalytic Solid State Hydrogen Storage?
Despite the advantages, several challenges exist:
1. Thermodynamics vs. Kinetics: Finding a balance between the thermodynamic stability of the storage material and the kinetics of hydrogen release is challenging. 2. Catalyst Deactivation: Catalysts can degrade over time, losing their effectiveness. 3. Material Costs: Some catalysts, like platinum, are expensive, which can hinder large-scale applications. 4. Hydrogen Capacity: Achieving high hydrogen storage capacity while maintaining fast kinetics and low operating temperatures remains a significant challenge.
