abstract = {Co-generation of hydrogen with value-added by-products is a
promising route for affordable low-carbon hydrogen. This
work presents a system for and a technoeconomic analysis of
hydrogen with the co-generation of chlorine and sodium
hydroxide from waste brine. The system uses a conceptual
triple-junction gallium arsenide (3-J GaAs)-based
photoelectrochemical (PEC) reactor at high solar
concentrations (50–500x). The base case of 200x solar
concentration results in a solar-to-chemical (SCE)
efficiency of $15\%$ and a levelized cost of hydrogen (LCOH)
production of $15.76/kgH2. Revenue from by-products
($45.36/kgH2) is critical for offsetting the operating
costs, with sodium hydroxide constituting 64\% of total
by-product revenue. The sensitivity analysis showed that
under favorable combinations of the key variables (sodium
hydroxide price, waste brine pretreatment price, and PEC
replacement lifetime) PEC hydrogen generation from waste
brine would be viable and have prices reaching $0.78/kgH2.},
