H2 has been selected as a government innovative product with their flow battery 'EnerFLOW 430' and is targeting the domestic public ESS (Energy Storage System) market. The advantage of flow batteries is that they use water-based aqueous electrolytes and do not cause a fire or explosion risks. The company plans to preemptively obtain orders for flow batteries for ESS in public projects that allow private contracts by selecting the innovative products.

The Ministry of SMEs and Startups announced that 'EnerFLOW 430', a flow battery-based energy storage system (ESS) developed by H2, has been selected as an 'Excellent R&D innovative product'.

H2 was selected as the innovative product for the first time in the domestic flow battery industry. The innovative product is selected and designated by the Ministry of SMEs and Startups when their product is technologically innovative and recognized by public in R&D sector.

EnerFLOW 430 is a flow battery ESS product that can be linked with new and renewable energy. A flow battery is a non-flammable battery that does not pose a fire risk by using a water-based electrolyte solution. It is safer than lithium-ion batteries that use electrolytes with high fire risk as the main material.

H2stated, "EnerFLOW 430 can be used for more than 4 hours with a 75kW output, and it is commercialized as a large-capacity module and the capacity can be expanded from tens of kW to hundreds of MWh through parallel expansion method."

As EnerFLOW 430got selected as the Innovative Product, H2 took an advantageous position in the competition to win ESS projects ordered by public institutions. According to the Ministry of SMEs and Startups, for innovative products, private contracts are possible rather than competitive bidding. The Ministry of SMEs and Startups plans to support H2 product promotion and matching if there is demand in public bidding.
H2 plans to further expand the supply of EnerFLOW 430 to the public ESS market as its technology has been recognized by the government. According to the industry officials, it is known that 198 public institutions are planning to install ESS flow batteries.

H2 official stated, "The flow battery is expected to be used for various purposes, such as replacing fossil fuel power generation, relieving the output limit of wind power generation, reducing peaks, and resolving bottlenecks in transmission and distribution networks."
