Vinatech

VINATech Co., Ltd. is a South Korean manufacturer of energy storage and hydrogen fuel cell components, headquartered in Jeonju. Its two main product families are supercapacitors — electric double layer capacitors (EDLCs), pseudo-EDLCs, lithium ion capacitors (LICs) and polymer/hybrid capacitors — and fuel cell materials, where the company produces carbon supports, catalysts, membrane electrode assemblies (MEAs) and separators. VINATech also supplies customized Hy-Cap modules and systems in which capacity, voltage, current, size and balancing circuitry are configured to a customer's specification, as well as battery hybrid systems. The company additionally lists deodorant products among its manufactured goods.

Target applications span smart factory logistics and material handling (AGVs, rack masters, OHT, CSC, RGC), smart grid and renewables (frequency-regulation ESS, voltage sag protectors, wind turbine UPS), mobility (hybrid vehicle auxiliary power, UAM, trams), modules for wind power and data backup such as SSD backup and e-Latch, AI data centers, smart IoT and metering, and defense and aerospace uses including military vehicles, self-propelled guns, missiles and electric propulsion systems. On the fuel cell side, VINATech positions its proprietary catalyst and carbon support technology as central to improving fuel cell efficiency and durability.

The company was founded in 1999 and listed on the KOSDAQ in 2020, trading under the code 126340. It reports 186 domestic and 8 foreign patents and about 30 points in its global network. Reported headcount figures differ across sources, at 168 employees in one financial data profile and approximately 66 in another aggregator listing.

Business model

VINATech researches, develops and manufactures components — supercapacitors, capacitor modules and fuel cell materials — that it sells to industrial customers and OEMs, including standard catalogue parts and custom-engineered modules built to customer specifications.

Revenue comes from sales of supercapacitors, capacitor modules and systems, hybrid/polymer capacitors and fuel cell materials, including large supply contracts and project orders. The company has set a target of KRW 1 trillion in sales by 2030, driven in part by AI data center demand.

Traction

Reported order wins of KRW 6.8 billion (June 2025) and KRW 10.6 billion (October 2025); a large-scale supercapacitor supply contract with Bloom Energy and MEA deliveries to fuel cell makers reported in December 2025; MEA supply agreement with Doosan Mobility and an ONiO development partnership in February 2026. One aggregator estimates annual revenue at about $27.4 million, an estimate derived from comparable companies rather than reported financials.

Latest developments

In February 2026 VINATech announced an MEA supply contract with Doosan Mobility for building fuel cells and a strategic partnership with ONiO to jointly develop a batteryless IoT power architecture combining VINATech supercapacitors with ONiO's ultra-low-power MCU platform. In July 2026 VINA Enesol launched 100V hybrid polymer capacitors for 48–72V power systems. Korean coverage in December 2025 described a two-track push into supercapacitor modules and MEAs for PEM water electrolysis, a large supercapacitor supply contract with Bloom Energy, MEA deliveries to domestic fuel cell makers, a new carbon technology institute focused on carbon supports, and exploration of the US PEM electrolysis market. Financial filings summarized in market coverage record several capital inflows during 2025 and 2026, a KRW 15.135 billion investment by VINATech into affiliate Vinatech Vina in June 2026, the divestment of KRW 20.6 billion of treasury shares in February 2026, and order wins of KRW 6.8 billion and KRW 10.6 billion in 2025.
