Remote coastal communities often rely on diesel generators for power. Electricity rates in these locations can exceed 1 $/kWh. Also, many remote communities lack modern water treatment infrastructure and water quality is often compromised. We are developing osmotic processes to improve the efficiency of clean water and electricity generation in remote communities.
We develop multi-domain models of water, salt, and heat transport to ensure the effective use of thermal energy to enhance osmosis.

We develop active real-time controllers for feed flow rates, draw flow rates, applied pressures, and temperatures to greatly improve osmosis performance.

We develop osmotic processes to generate electricity in stand-alone power plants, or to recover energy from desalination plants.
