• Novel approach to produce vanadium electrolyte directly from heavy oil waste ash
    • The only existing technology for directly producing vanadium electrolyte from waste
    • Eliminating of vanadium penta-oxide production and the low temperature process design for vanadium electrolyte lead to less GHG emissions compared to conventional extraction and production processes
    • Estimated reduction in production cost of vanadium electrolyte is up to 60%
    • Less environmental (GHG and land) emissions than conventional methods
    • Can be one of the cost-effective solution to meet the demand of the growth in energy storage
    • US patent (US2017/0349971 A1)
    • Leveraged governmental (Alberta and Canada) support (funding and in-kind)


      The use of extracted vanadium from secondary source for vanadium redox flow battery (VRB) application is the main interest of WAVE project. EnSciTech brings an innovative picture into vanadium electrolyte production to address the high cost of the electrolyte and insufficient supply of vanadium for VRB application.   Though initial market for vanadium in batteries, is supplied via primary sources (i.e. vanadium mining), heavy oil waste (such as oil sands waste in Alberta) can potentially be a significant secondary source which can be integrated into market suppliers for vanadium electrolyte.

      The waste ash contains high concentration of vanadium, nickel and carbon. All three can be used in batteries. EnSciTech has developed a technology for direct production of vanadium electrolyte from waste and is aiming for pilot scale in Q3 – 2019.


  • Decreases the production cost of vanadium electrolyte by eliminating mining and production of vanadium penta-oxide,
  • Reduces logistics of vanadium mining and transportation cost of vanadium as feedstock to vanadium electrolyte manufacturer,
      • Increases process intensification via integrating two processes (vanadium extraction and direct production of electrolyte)
      • Minimizes class I hazardous landfill requirement for the waste ash by utilizing the waste stream as feedstock to produce vanadium electrolyte.
