Further to the Prior Release, the Company wishes to clarify that the proposed recipients of the Consideration Shares will be: KORID, as to 7,500,000 Consideration Shares; DST Co., Ltd. ("DST") (KOSDAQ: 033430), as to 7,500,000 Consideration Shares; and LKAT Co., Ltd. (LKAT") as to 5,000,000 Consideration Shares. Each of DST and LKAT are shareholders of KORID. In connection with the Transaction, the Company proposes to incorporate a United States subsidiary to principally operate the proposed joint venture obligations of the Company ("DIA US"). The board of directors of DIA US will be comprised of two nominees of the Company and two nominees of KORID. The Company also proposes to reconstitute its board of directors in connection with completion of the Transaction to include three nominees of the Company, and two nominees of KORID.

This press release refers to a joint venture to construct a factory (the "Factory") in the United States for the purpose of producing Vanadium Redox Flow Batteries and energy storage systems.

Factory Design

Preliminary Factory footprint, process flow, equipment and personnel requirements have been completed by KORID for Phase I of a Vanadium Flow Battery Factory with an annual output capacity of 50MW and 200MWh of storage.

Battery Design

KORID's proprietary Vanadium Flow Battery has been developed and tested over the past 10 years and is patent protected. The flow battery design allows for limitation of storage only based on the capacity of the electrolyte tanks versus the fixed capacity of lithium-ion. The battery is non-flammable and non-explosive. There is no degradation as a result of cycling, partial charging, or time with a 100% depth of discharge and projected lifetime of 20 years. Battery efficiency is currently rated at up to 80%. The battery is scalable into the MW-range through simple parallel connection of multiple units. The systems are shipped in self-contained weatherproof and securely protected housing. The systems can be managed and maintained by remote or online maintenance through intelligent battery management. Temperature management and climate controlled containers eliminate weather impact on energy efficiency.

The battery is composed of four primary components: electrolyte tanks, cell stacks, power conversion system (including control system, communications, inverter, electrical wiring, etc.), and pumps / balance of plant equipment (Figure 1). The systems are designed for containerized deployment in twenty or forty foot containers. The forty foot design has a capacity of 100kW output, 400kWh capacity.

Cell Stack

KORID has manufactured four cell stacks to date including 2.5kW, 5kW, 10kW, and 25kW (Figure 2). KORID has developed and is currently testing a 50kW cell stack for high usage industrial and grid scale utility and renewables applications.

Grid Scale Mass Storage

Designs have been completed for a 3.6MW output system (Figure 3) to meet the demand for grid scale applications. There are a variety of applications to support both renewables and existing infrastructure as well as energy security. Placing batteries at substations or near high demand areas reduces need for new infrastructure such as transmission lines, substation capacity, and traditional power plants or hydro dams. The power is often wasted in the night only for a lack of battery capacity. Grid scale energy storage systems allow for charging at night during very low demand times (off peak) and release that energy during the day during peak demand reducing the need for new transmission lines or power plants. This both increases overall efficiency and provides backup/standby power for energy security and a robust and efficient energy infrastructure.
