This FOA supports research, development, and potential demonstration of early stage technologies that can significantly reduce the costs of desalination powered by solar thermal energy. 

Applicants will be expected to propose ideas that have the potential to dramatically decrease the cost of producing solar thermal energy, advance early-stage thermal desalination technologies, or design novel integrated systems that creatively use solar thermal energy to lower the cost of producing fresh water.

It is anticipated that the FOA may include the following Areas of Interest:

Area of Interest 1 – Low cost solar thermal heat - innovative concepts that have the potential to lower the cost of solar thermal collection, transport, and storage below conventional methods of generating heat.

Area of Interest 2 – Innovative thermal desalination techniques - Novel, early-stage thermal desalination technologies that are well suited to be coupled with solar generated heat.

Area of Interest 3 – Solar thermal integrated desalination - Integrated solar thermal desalination systems showing the potential for low-cost desalinated water.

Area of Interest 4 – Solar thermal desalination analysis - Analytic tools, such as systems models, for economic evaluation and resource optimization with solar thermal desalination.
