NGK starts operation of NAS battery system for KEPCO

Lagos — NGK Insulators, Ltd, NGK, has announced that it has an order from BASF Stationary Energy Storage GmbH, BSES, a subsidiary of German chemical manufacturer BASF SE. and has started operation of a NAS® battery system for storing electric power delivered to South Korean electric power systems manufacturer G-Philos Co., Ltd.

The NAS battery system in Naju comprises 4 battery containers and (1) has a maximum 1,000 kW-dc power and 5,800 kWh-dc dischargeable energy under a demonstration project for comparison of performance of stationary storage batteries at a testing site of Korea Electric Power Corporation, KEPCO, in Naju City, South Korea.

KEPCO is promoting the introduction of storage batteries to expand domestic renewable energy use, and the results of this demonstration project will set performance standards for large storage batteries in South Korea.

The highly durable NAS battery, which has a large storage capacity and is able to discharge over a long period, was selected for this project because of its high reliability based on an extensive track record of use in the stabilization of widely fluctuating renewable energy and because it has received high praise for its certification and evaluation reports from UL Solutions, a global thirdparty safety science company.

NGK previously delivered a NAS battery (2) to G-Philos in 2020 for the first Power-to-Gas (P2G) * demonstration project in South Korea, carried out by Korea Midland Power Co., Ltd., KOMIPO, at Sangmyung Wind Farm, Jeju Island, South Korea.

The NAS battery was used as a storage battery for storing and discharging surplus electric power from wind power generation and supplied electric power to hydrogen manufacturing equipment in a stable manner, thereby realizing the manufacture of green hydrogen without impacts from the significant fluctuations of wind power.
