Simulation study on enhancing hydrogen production in an ocean thermal energy (OTEC) system utilizing a solar collector

This article reports the simulation study on the performance of utilizing a solar collector at the inlet of an evaporator to provide auxiliary heat into a system for hydrogen generation in an otec cycle. the conventional method of otec is simulated by fortran programming and the results were compared with the presence of solar collector on the system. in the simulation experimental,the incoming temperature of warm seawater was boosted by using a flat plate solar collector. for the purpose of the experiment,a 100 kw otec cycle that was designed incorporated a solar boosting capability. its thermodynamic efficiency was then compared through a series of simulation involving several control parameters. the results reveal that the proposed solar boosted otec enhanced the thermal efficiency,te. increase in solar power absorption can increase the net power output,thus increasing the amount of hydrogen produced. the results obtained provided insights,from a thermodynamic perspective,on the outcome of combining sustainable energy with solar thermal energy to improve the system performance. © 2015 penerbit utm press. all rights reserved.
