A recent surge of studies about renewable energy is now the focus of the world. Salt water
is known for its high concentration level of electrolytes, if enough water is use it can
harness electricity which can provide energy for light, electrician equipment’s, appliances
and etc. The researchers describe the use of NaCl (aq.) as the energy source (catholyte) in
a rechargeable saltwater battery. Reduction/oxidation reactions of Na/Na+ at the anode and
evolution/reduction reactions of gases (mostly O2, with a potential Cl2) in seawater at the
cathode power the battery. The system utilizes a interconnected fuel cells and fabricated
from corrosion-resistant stainless steel 304, operates efficiently, reaching full power within
3 minutes with the electrical connection of series, parallel, and series- parallel. Testing
demonstrated a positive result, particularly with the series-parallel configuration, which
produced increasing power outputs of 3W, 12.6W, and 24W at 10, 15, and 20 minutes,
respectively. The study emphasizes osmotic power generation's potential as an off-grid
community's sustainable energy source. The device was evaluated by 40 respondents,
comprising both professional and students, who rated its performance as “Very Good”,
achieving a mean score of 3.88. It shows an optimistic perspective regarding the potential
and performance of the device, suggesting that it holds promise for achieving favorable
outcomes.
