A high-tech chemical company has purchased the last available water in the Nueces River to make hydrogen and ammonia for export.

Recommended VideosChemical company Avina Clean Hydrogen Inc. has purchased the last available water supply from the Nueces River of South Texas, raising concerns of regional scarcity as reservoirs dwindle and drought persists.plant plans to separate the hydrogen from water, convert it to ammonia and export it as a high-tech fuel alternative to oil and gas.

That’s where Avina found the means to purchase 5.5 million gallons of treated Nueces River water per day—enough for all 38,000 residents of Calallen and Robstown to each flush their toilets 90 times daily—for the next 25 years. A spokesperson for Avina in New Jersey, Karen White, said the company “takes seriously the water/energy nexus and is engineering the most water conscious plant design, opting for dry cooling, reuse and reduction wherever possible.”

So instead, scientists devised an alternative: convert the hydrogen to ammonia , ship it overseas then re-convert to hydrogen. It’s an inefficient process. Up to 40% of the original energy input is lost in the production, conversion and re-conversion of the hydrogen, said Hugh Daigle, an associate professor of petroleum engineering at the University of Texas who has studied the hydrogen economy. But, it produces a carbonless fuel that can power heavy vehicles without harmful emissions.
