The Zn Reactor is an electrochemical cell with a distinctive structure:
Global patent protection is pursued. Patents were granted in the United States and China and are pending in more countries.
The electrochemical cell has a simple mechanical operation.
During charging zinc metal is electrochemically deposited in the electrodes in the charging section and falls, when wiped off from the electrodes, into the discharge section and the storage space below.
During discharging, the zinc in the discharging section is dissolved into the solution and is circulated back to the top of the charging section to be deposited back into metal again.
Charging and discharging cycles are created as the operation processes repeat.
e-Zn is currently leading an industrial consortium to conduct a project awarded by SDTC to demonstrate the storage of solar energy with a Zn Reactor system in an off-grid setting. It consists of 5kW solar panels and 1kW/24 hours of energy storage.
Consortium members include Canadian Solar, Broy Engineering and NewESolar.
The Zn Reactor has low cost scalability for storage capacity based on three principles:
