“Seawater battery-based smart buoys can monitor and collect over 15 different marine data, such as salinity, pH, and water temperature, as well as the location and range of fishing grounds. As it is a promising alternative for safe and scalable energy storage, we expect its further applications in the ocean sector!”

The 2020 Regional Vitality Project Project, carried out amongst UNIST and Korea Institute of Maritime Science and Technology (KIOST) is producing concrete outcomes. The firm to learn from this mission is KLabs Inc., which is about to launch smart buoys that utilized seawater batteries.

The “Seawater Battery-based Multi-Purpose Buoy” by KLabs Inc. is a tool that may monitor and accumulate varied information on the marine environment. A seawater battery that makes use of the naturally-abundant seawater as a sodium supply to cost and discharge electrical energy is a key characteristic of this gadget. Besides, with 3D printing, mass-customized merchandise are additionally potential with out having any bearing on prices.

The demonstration of latest product improvement is important in that each analysis institutes and personal corporations have cooperated for the reason that early phases of the brand new product improvement course of. In addition, it’s anticipated that each the commercialization and on-site software can be accelerated, as prototypes have been personalized to satisfy particular enterprise wants.

This prototype demonstration is a part of the Regional Vitality Project Project, promoted by the Ministry of Trade, Industry and Energy (MOTIE). Since the choice of demonstration mission to put the groundwork for the event of ‘Maritime-Specialized Power Supply System and Maritime Equipment,” in May 2020, UNIST and KIOST have actively been working with the businesses within the Ulsan area to provide and exhibit seawater battery-based merchandise.

Meanwhile, UNIST has been main the seawater battery analysis for the reason that improvement of the world’s first seawater battery in 2014. With the help from the Korea Electric Power Corporation (KEPCO), Korea East-West Power Company Ltd. (EWP), and KIOST, the middle continues to push forwards commercializing the seawater batteries. Besides, with the completion of the development of the Seawater Resources Technology Research Center of UNIST in November 2020, UNIST is taking the lead in upgrading analysis on seawater batteries.
