A next-generation battery free from fire concerns is just one step away from commercialization.

TNP Solution, a specialist in next-generation secondary batteries, has successfully completed a field demonstration of an energy storage system (ESS) linked to solar power in a multi-housing complex using aqueous zinc-ion batteries, and is accelerating its push toward commercialization.

The company announced that it completed the "Demonstration of High-Safety Energy Storage System Based on Aqueous Zinc Batteries Linked to Solar Power" as the lead organization for the "2025 Climate Change Response Innovative Technology Demonstration Project," which is being promoted by Seoul City and managed by the Seoul Research Institute.

Professor Kim Chan-hoon's research team at Hanyang University participated as a technology cooperation partner, while the Seoul Housing and Communities Corporation (SH) served as the demonstration site operator.

This demonstration is significant because it involved operating an aqueous zinc-ion battery-based ESS linked to solar power generation equipment in an actual multi-housing complex where residents live, rather than in a laboratory setting. The company explained that through the process of storing generated solar power in batteries and supplying it when needed, it verified the feasibility of charge/discharge control, integration with power conversion devices, and system operation.

For batteries to be installed in living spaces inside and outside buildings, verification is required not only for cell-level performance but also for safety, system control, and operational reliability. TNP Solution plans to utilize the operational experience gained from this demonstration in the product development of future urban-type ESS and building energy storage systems.

Kang Seong-gu, CEO of TNP Solution Co., Ltd., stated confidently during a phone interview with this outlet, "The safety of batteries is a value that cannot be compromised in spaces where actual citizens carry out their daily lives." He added, "This demonstration marks a turning point proving that aqueous zinc batteries are high-safety energy solutions immediately applicable in real-life environments, going beyond the laboratory level. We will actively pioneer the urban power market, which absolutely requires safety and reliability, differentiating ourselves from markets focused on high density."

Meanwhile, the "aqueous zinc-ion battery" is a secondary battery that has recently attracted attention. As the adoption of solar power and distributed power sources expands, total costs—including energy density, fire safety, installation costs, and maintenance fees—are becoming increasingly important in domestic and international ESS markets. In particular, in spaces where people reside or essential facilities are located, such as multi-housing complexes, hospitals, data centers, and telecommunications facilities, battery safety is a core condition for adoption.

An aqueous zinc-ion battery is a secondary battery that utilizes a water-based electrolyte and a zinc metal anode. By using a non-flammable aqueous electrolyte, it can minimize the risk of ignition from the electrolyte itself. Additionally, by utilizing relatively abundant zinc, it possesses competitiveness in terms of raw material and manufacturing costs.

Although it may have lower energy density than lithium-ion batteries, it is gaining attention as an alternative or complementary technology for stationary ESS, UPS, emergency power for telecommunications facilities, and industrial applications where safety and economic efficiency are prioritized.
