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

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

Since it is composed of a water-based electrolyteand there is no possibility of fire, it is recognized as the secondary batterywith excellent safety and has long cycle and large capacity receiving worldwideattention. In this exhibition, the company exhibited the EnerFLOW 330 model andguided directly to the visitors.

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

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

The 18th International Green Energy Expo isKorea’s largest, one of Asia’s top 3 and the world’s top 10 new and renewableenergy exhibitions, and the only exhibition jointly organized by the four majorassociations. 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 andorganized by EXCO, KNREA, KOPIA, KWEIA, and KHIA.
