Black & Veatch Completes an Independent Assessment of ViZn Energy’s Z20 and GS200 Redox Flow Energy Storage Systems

Black & Veatch gives glowing report on ViZn Energy Systems

AUSTIN, Texas - ViZn Energy Systems Inc. (ViZn), a leading provider of energy storage systems for utility and microgrid applications, as part of its ongoing commitment and comprehensive approach to transparency, quality and reliability, selected and hired the world-leading engineering, construction and consulting firm Black & Veatch to conduct an independent assessment of its Z20 and GS200 Redox Flow Energy Storage Systems. In the process, Black & Veatch methodically reviewed documents and test results, visited the facilities of both ViZn and its manufacturing partner Jabil, and reviewed the performance of ViZn's energy storage technology.


In its assessment of ViZn's Z20 and GS200 flow batteries, Black & Veatch stated that it believes:

• The ViZn batteries outperform systems with lithium-based chemistries at high ambient temperatures due to the fact that the ViZn energy storage systems perform well at high ambient temperature without any HVAC load.
• Jabil's vendor qualification and monitoring process is well established and should be able to ensure quality materials and components for ViZn's products.
• ViZn's zinc-iron redox storage technology is designed and manufactured for large scale energy storage applications. Key differentiators from other flow battery technologies are: safety and non-flammability of the electrolytes and chemistry, abundance of core raw materials, a 20-year expected system life, an HVAC system is not required to operate at high ambient temperatures, and ViZn's battery life and warranty are independent of the duty cycle imposed on the system.
• ViZn's senior management team has experience in the manufacturing commercialization of novel products in the energy industry and appears to have the skills required to manage ViZn.

"The results of Black & Veatch's assessment are consistent with our own internal test results for performance and longevity and, in some cases, exceeded our expectations," said Ron Van Dell, President and CEO of ViZn Energy Systems. "We've dedicated an extensive amount of R&D to continuously improve our batteries which, we believe, has resulted in the best value energy storage technology on the market."

ViZn sought Black & Veatch's expertise in conducting the independent assessment to demonstrate bankability and ensure project financing of ViZn systems. Black & Veatch's comprehensive assessment evaluated the design, performance, and manufacturing of ViZn's Z20 and GS200 flow batteries and assessed ViZn as a company. ViZn is happy to share the report with interested parties upon request.

ViZn's flow batteries are designed with the customer in mind, which is why the company has built in both high-power and long-duration capabilities, low O&M and a 20-year operating life, allowing end users to incorporate multiple value streams and realize more favorable payback periods than other energy storage technologies on the market. ViZn is currently building the largest flow battery in North America and is on track to be the largest global producer of flow batteries by the end of the year.

SolarEdge Technologies - EV Charging Single Phase Inverter

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
