The U.S. Navy has made more progress in their quest to get clean, cheap fuel from seawater.
Using a machine called an Electrolytic Cation Exchange Module (E-CEM) that converts seawater to carbon dioxide and hydrogen, the Navy demonstrated proof-of-concept for converting CO2 to hydrocarbons, which can be used to produce liquid natural gas, compressed natural gas, and the military grade liquid fuels F-76 and JP-5.
Last year, synthetic fuel from the E-CEM was used to power an internal combustion engine in a commercially available radio-controlled aircraft.
Seawater contains an abundance of CO2—about 140 times greater than that in air.
It won’t be long before we see this technology moving into powering fuel cell cars.
Depending on who you talk to, the production cost varies from $3 to $6 per gallon, and one imagines that with economies of scale and improved technology, that price will come down.
