From Hydrogen to CO₂: Applying Adsorption-Based Gas Storage Technologies to Enhance Compressed Gas Energy Storage Systems

Résumé

Hydrogen storage is essential for advancing hydrogen technologies, though challenges remain due to hydrogen's low volumetric energy density at ambient conditions. Physisorption on porous materials shows promise for enhancing this density, enabling efficient and reversible storage. Similarly, Compressed CO₂ Energy Storage (CCES) relies on high-pressure CO₂ storage, using compressed CO₂ to generate electricity on demand. Achieving efficient CCES requires high-density CO₂ storage to maintain closed-cycle operation and optimize system efficiency. This study draws from advancements in hydrogen adsorption to improve CO₂ storage performance. Using COMSOL™ simulations, one models the heat and mass transfer dynamics in storage tanks, focusing on gas charging and discharging effects. The results show similar temperature profiles and pressure uniformity for H₂ and CO₂, though CO₂ generates more heat, reaching a peak temperature of 382 K compared to 341 K for H₂. This indicates that while hydrogen adsorption advancements aid CO₂ adsorption storage, further solutions are needed to manage heat dissipation effectively.
