Exergy-based sustainability assessment of continuous photobiological hydrogen production using anaerobic bacterium Rhodospirillum rubrum

The present research work was aimed at analyzing a continuous photobioreactor for hydrogen production from syngas via Rhodospirillum rubrum from exergetic point of view. Exergy balance equation was developed for the investigated photobioreactor based on both conventional exergy and eco-exergy concepts in order to determine its exergetic performance parameters. Two new exergetic criteria called the process exergetic efficiency and normalized...
