H2 participated in the International Green Energy Expo 2021 held at EXCO, Daegu from April 28 (Wed) to 30 (Fri) and introduced its Vanadium Redox Flow Battery ESS.

In a vanadium redox flow battery with a life span of 20 years, an electrolyte designed independently from the outside circulates inside the stack, causing oxidation and reduction reactions. Electric energy is stored in the form of chemical energy in the electrolyte so that it can be charged and discharged.

Since it is composed of a water-based electrolyte and there is no possibility of fire, it is recognized as the secondary battery with excellent safety and has long cycle and large capacity receiving worldwide attention. In this exhibition, the company exhibited the EnerFLOW 330 model and guided directly to the visitors.

H2 Business Development Team Leader Lee Si-woo introduced the company by saying, “H2O is a company that manufactures, produces, and supplies vanadium redox flow batteries with Korea’s pure technology. Our biggest merit is that it can be used for more than 20 years.”

He added, “The main models are EnerFLOW 430 and EnerFLOW 330, and 430 has specifications from 75Kw to 385Kw, and the 330 has specifications from 10Kw to 40Kw.”

The 18th International Green Energy Expo is Korea’s largest, one of Asia’s top 3 and the world’s top 10 new and renewable energy exhibitions, and the only exhibition jointly organized by the four major associations. The exhibition covers △Solar power △ESS (energy storage system) & battery △Smart grid technology △Wind power and △New and renewable energy. This exhibition is hosted by Daegu Metropolitan City and Gyeongsangbuk-do and organized by EXCO, KNREA, KOPIA, KWEIA, and KHIA.
