摘要

The increase in greenhouse gases emissions and associated climate change could have enormous effects on energy and water resources. Renewable energy represents the most promising and sustainable alternative to preserve the environment. Reverse osmosis represents the main desalination technology for producing freshwater. However, the disposal of the resulting brine is an important environmental consideration. Additionally, there is an interest in creating green hydrogen from water using water electrolysis. This paper presents an experimental study that uses brine to produce green hydrogen, oxygen, and salt in order to overcome water scarcity and potentially reduce the brine disposal impacts. For the first time, an experimental investigation is carried out to create hydrogen through electrolysis from brine. The experimental study is conducted to create green hydrogen using electrolysis from high water salinity (10 to 100 g/l). The results show that increasing the water salinity has increased hydrogen, oxygen, and salt production. The findings reveal that as the salinity raised from 10 to 100 g/l, the production of hydrogen increased from 3.5 to 18.3 ml and oxygen production increased from 1.75 to 9.15 ml, while the production of salt increased from 10 to 100 g. The results could help in producing green hydrogen, oxygen and salt from high saline water that overcomes water scarcity and leading to zero liquid discharge from desalination process. The new technique is also friendly environmental and using the produced green hydrogen will help in reducing the greenhouse gasses emission that protects the environment and slows down climate change.
