Desalination using a clathrate hydrate technology

Project Goals and Description:

Clathrate hydrates are solid inclusion crystals comprised of hydrogen-bonded water cages that can trap small guest molecules (e.g., CO2). In the presence of saline solution, clathrate hydrate crystals will form, while excluding the salt ions from the water cages, such that separating the clathrate hydrate crystals from the concentrated saline solution can produce fresh water. A key challenge to advance the clathrate hydrate technology for desalination is controlled crystal nucleation and growth, which will be the focus of this project.
