Effective recovery of methane from methane hydrate and storage of various gases in clathrate hydrates

  • 7.Affordable and clean energy
  • 13.Climate action
  • 14.Life below water

Objective

To exploit effective utilization of water ubiquitously distributed on the earth as an energy resource from the viewpoints of energy cycle and mining of chemical energy.

  • Recovery of methane from methane hydrate
  • Development of an environmentally friendly approach for hydrogen and ozone storage in clathrate hydrates

Present activities

  • Establishing theoretical methods to estimate the thermodynamic stability of  methane and hydrogen hydrates only from the intermolecular interactions
  • Elucidation of the formation and dissociation mechanisms of methane and CO2 hydrates by large scale computer simulations
  • Exploration of the structure and stability of semiclathrates for utilization as cooling materials 


Future prospects 

  • Exploration of hydrophobic effects in conjunction with the stability of clathrate hydrates
  • Theoretical prediction for the stability of N2 and CO hydrates under cryogenic conditions contributing to planetary sciences
