Low cost hydrogen production by anion exchange membrane electrolysis: A review
TL;DR: Anion exchange membrane (AEM) water electrolysis is a hydrogen production method that is achieved with an AEM, using electricity as discussed by the authors, which is still a developing technology; therefore, with a view to using it to eventually achieve commercially viable hydrogen production, AEM electrolysis requires further investigation and improvements.

Hydrogen production from rice winery wastewater in an upflow anaerobic reactor by using mixed anaerobic cultures
TL;DR: In this paper, a 3.0-l upflow reactor was used to investigate individual effects of hydraulic retention time (HRT), chemical oxygen demand (COD) concentration in wastewater (14- 36 g COD/l), pH (4.5-6.0), and temperature (20-55°C) on bio-hydrogen production from the wastewater.
