Zero Emission Coal Power Plant Design Makes Carbon Capture Profitable
Power Plant Produces Hydrogen, Only Raw Materials Needed are Coal, Salt and Water
The only raw material required is coal (or natural gas), sodium chloride (salt) and water. The process locks carbon dioxide (CO2) and carbon monoxide (CO) into sodium bicarbonate and sodium carbonate.
Florida International University (FIU, Miami, Florida) FIU Center for the Study of Matter at Extreme Conditions Director Surendra Saxena developed the system of reactions for a partial sequestration of carbon (CO2 and CO) from coal burning plants and zero emission production of hydrogen and hydrides. The only raw material to be used is salt (sodium chloride, NaCl), coal and water or a metal for the hydride. Sodium hydroxide (NaOH) generated from the chloride is used for locking carbon dioxide in sodium carbonate and bicarbonate, according to Saxena in U.S. Patent Application 20100028241
Saxena process also generates hydrogen from the reaction. The reaction takes place in a closed system to achieve zero emission of carbon gases while generating hydrogen from the reaction. The process of carbonation is not a direct conversion of NaOH to Na2CO3 but is a result of a reaction with other solids and gases usually producing hydrogen in important amounts.
