About Osmotic Power
Osmotic Power is the energy available from the difference in salt concentrations between two solutions. New Mexico produces 14 billion gallons per day, or approximately 28 billion gallons per year, of high salt concentration wastewater from oil and gas production in the Permian Basin, San Juan Basin, and Raton Basin.
More than half (56%) of this produced water is injected to enhance oil recovery while the remainder is disposed of via salt-water disposal (SWD) wells. In southeastern NM, there are approximately 630 SWD wells, each holding produced water from 40 oil wells with a mix of 1% to 40% salinity.
Pressure Retarded Osmosis can be used to transform this produced water into renewable energy:
