Adsorption based biomethane storage for vehicular applications

Subcategory (under Clean Energy): Cross Cutting
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)

Adsorption-based gas storage (ANG) system on sustainable materials is an alternative to the compression-based gas storage (CBG/CBG) methane rich biogas or natural gas. Currently, higher pressure compression of methane rich gas requires a thick- walled cylinder, larger space, and high energy which makes it risky operation. Therefore, adsorption is another way seen as an alternative in which the gas is stored in porous materials. The porous materials derived from biomass-based activated car- bons have received particular attention as adsorbents. In this technology pressurised gas is injected in the porous materials filled cylinder where the gas is stored. In the same direction we have developed several materials for the efficient gas adsorption which stored higher amount of gas compared to the compression at similar pressure and cylinder volume.

Salient Features/Advantages

  • Lesser severe methodology for material production
  • Higher gas storage than compression-based method at similar pressure and cylinder volume
  • More efficient and less risky operation
  • Highly porous materials developed with physicochemical method with higher packing density 
  • Great recyclability of the materials
  • Environment friendly approach competitively

Key Outcomes

  • Developed a methodology for hierarchical interconnected porous materials for higher storage of gas
  • Hard biomass such as coconut shell or woods are key for compatible pores and higher gas adsorption
  • High deliverable (80%) in first cycle and 100% deliverability from 9th cycle
  • Efficient methodology as supported by life cycle impact assessment
  • Several publications in international journals.
