Structural phase transitions and the self-preservation effect in clathrate hydrates

Cel

This proposal brings together six world-leading groups on the theory of gas hydrates in order to solve some of the major unresolved issues in hydrate research. The project will:

- Produce a major generalisation of the existing theory of hydrate stability, so that it can account for phenomena such as multiple occupancy of individual cages and mutual guest-host couplings that have been discovered in recent experiments;

- Develop a quantitative theory for the self-preservation effect in methane hydrate, and thereby provide a fundamental understanding of why this effect appears to be limited to a very narrow range of temperature and guest composition;

- Produce a viable microscopic theory for the growth kinetics of gas hydrates under a wide range of pressures and temperatures, and for a variety of guest molecules; and

- Produce a detailed characterisation of the molecular structure and thermodynamic properties of a range of hydrate interfaces, and novel high pressure hydrate phases.

These developments are both important and timely. The properties of gas hydrates are already a major topic for research in most of the leading developed countries. Indeed, interest is still growing, motivated by a number of important applications for hydrates that are likely to emerge in the near future. These applications include exploitation of huge natural reserves of methane hydrate as an alternative to fossil fuel reserves; the probable role of CO2 hydrate formation in all the major greenhouse gas sequestration strategies that have been proposed; and the development of a number of promising and novel alternative energy technologies that are being developed to exploit the unusual - if not unique - properties of gas hydrates.

The theoretical developments proposed within this project are vital for the realisation of each of these applications. Achieving these developments in the near future is extremely challenging. These goals are achievable, but only with the close collaboration between researchers of proven and complementary expertise on the theory of gas hydrates that is proposed herein.
