Background:

Deliverable methane capacity is crucial for efficient gas storage in materials.
Current understanding relies on simplified models and rules of thumb for material selection.
Nanoporous materials are promising for methane storage applications.

Purpose of the Study:

To identify key thermodynamic factors governing methane deliverable capacity in nanoporous materials.
To develop and validate statistical thermodynamic models for predicting material performance.
To challenge and refine existing guidelines for selecting methane storage materials.

Main Methods:

Development of several statistical thermodynamic models.
Comparison of model predictions with classical thermodynamics and molecular simulations.
Screening of extensive zeolite structure databases (IZA and hypothetical).

Main Results:

Statistical models and simulations do not support a universal optimal heat of adsorption of 18.8 kJ/mol for methane storage.
An optimal heat of adsorption exists but is structure-dependent, ranging from 8 to 23 kJ/mol.
Established a relationship between material's molecular structure and optimal heat of adsorption.

Conclusions:

The optimal heat of adsorption for methane storage is not a fixed value but is intrinsically linked to the nanoporous material's structure.
The developed models provide a more nuanced approach to designing materials for effective methane storage.
This research offers improved criteria for selecting and designing advanced materials for gas storage applications.
