Design and analysis of a hydrogen production system using hybrid concentrated photovoltaic thermal system integrated with an organic Rankine cycle

This study evaluates an improved organic Rankine cycle (ORC) with a solar energy source for hydrogen production and presents functional results, validation, and sensitivity analysis. The increase in condenser outlet temperature causes a decrease in the total thermal efficiency, a decrease in the efficiency of the ORC, a decrease in the total electrical efficiency, and a decrease in hydrogen production. The most striking result is that the net generating power of the system is equal to 4200 W, which is equivalent to producing 0.02372 g/s of hydrogen and 0.0810 g/s of oxygen.
