Upcycling sulfate byproducts into carbon-negative sulfuric acid and green hydrogen - The Travertine Process
The Travertine process converts aqueous sulfate into sulfuric acid and caustic solutions through electrolysis, generating clean and competitively priced hydrogen. The process involves three primary units. Initially, electrolysis divides aqueous sulfate into sulfuric acid and caustic solutions. Subsequently, Direct Air Capture (DAC) utilizes the caustic solution to extract CO2 from the air, yielding a carbonate solution. Lastly, the carbonate solution reacts with sulfate byproducts to form minerals and regenerate aqueous sulfate through mineralization.
