CO2 removal and H2 production coupled with desalination

Desalination uses a significant amount of energy, producing CO2 to remove a significant amount of salt from seawater, both emitted as pollutants. Desalination plants dump left over salt brine into the ocean, which is harmful to marine life, and “indirectly emit” a significant amount of CO2, contributing to climate change. My solution uses the CO2 and brine to make marketable commodities: hydrogen gas for energy storage and baking soda that can be used as an environmentally friendly de-icing agent. Consuming the salts can potentially double the output of freshwater. Power and desalination plants commonly sit side by side to share ocean intakes for cooling water and desalination source water, and thus can work together to solve each other's problems.

How it benefits society

My solution combats climate change and brine pollution associated with desalination, thus enhancing this method of freshwater production that is steadily growing in demand worldwide.

John R. Hoaglund, III
Huntington Beach, California / Las Vegas, Nevada

Dr. Hoaglund is a geologist with more than 30 years of experience in environmental research, teaching, and consulting in the private sector, government, and academia. He received his BS and MS degrees in geology from the University of Wisconsin, then worked in Kansas with the Kansas Geological Survey to find supplies to replace the depleting Ogallala Aquifer, followed by environmental consulting on cold war legacy ground water contamination. He next completed his doctorate in geology from Michigan State University, completing a US Geological Survey regional groundwater model of the Michigan Basin used to calculate modern and Pleistocene groundwater and brine discharge to the Great Lakes and rivers in Michigan. He taught hydrogeology, groundwater modeling, environmental geology, and glacial and climate geology at the University of Michigan before joining Pennsylvania State University research on regional climate-hydrologic models, sponsored by the National Science Foundation, and groundwater nitrate studies, funded by the US Department of Agriculture. In 2007, Dr. Hoaglund moved to southern California, and resumed work on cold war legacy groundwater contamination. He founded Carbon Negative Water Solutions in 2010 to pursue energy consulting related to water resource development, desalination, renewable energy development, hydrogen production, and CO2 sequestration. He is currently on a long term contract with the Department of Energy working on the groundwater contamination of the Nevada Test Site related to cold war legacy nuclear testing. So he's already cleared at the DOE and ready to work with NREL!!!
