1.         Why Solar?

  • Growing industry of the future… renewable electricity is hitting critical mass and will go ‘viral’ in the next 5 years – from electric cars to roof shingles to sidewalk to mud huts in Botswana
  • The solar industry was roughly 1% of the 6,000 GW or US $2 trillion electricity market.  Over the next 20 years, Deutsche Bank expects the electricity market to double to US $4 trillion and expect the solar industry to increase by a factor of 10

2.          Why Silicon Metal (Si)? Because Silicon is THE Solar Metal

  • Solar Cells are needed to convert the Energy of the Sun directly into electricity
  • Solar Cells use Solar Grade Silicon Metal (SoG SI) to convert sun rays into electricity
  • One Watt capacity of a Solar Energy requires 5 grams of SoG Si

3.          What are the challenges?

  • Bottleneck in the production of SoG Si due to numerous barriers
    • High capital costs,
    • Multi-stage, complex smelting and refining processes,
    • High operating costs,
    • Large carbon and energy footprint

4.          What does HPQ provide?

  • A disruptive low cost, one – step, green technology solution: Pyrogenesis’ Purevap™ Reactor 
    • Purevap™ promises to eliminates several complex steps, high costs, and reduces not only carbon footprint but excessive by-products and energy consumption 
  • A completely vertical integrated solution, from the production of SoG Si directly from Quartz (SiO2) all the way to manufacturing high performance multi-crystalline and monocrystalline solar cells.
  • HOW?
    • The Purevap™ technology developed by Pyrogenesis is a new metallurgical process that allows a direct transformation of Quartz (silicon dioxide, SiO2) to Solar Grade Silicon Metal (SoG Si)
    • With the addition of Apollon Solar SAS to the Team, HPQ added to the partnership one of the leaders in transforming metallurgically produce SoG Si into high performance multi-crystalline and monocrystalline solar cells

5.          What advantage does HPQ have?

  • Pyrogenesis are world leaders in plasma torch and high temperature purification systems
  • Apollon is one of the world’s leaders in renewable energies, and high performance solar cells
  • HPQ owns the technology through its agreement and is funding the project for 90% interest
  • HPQ owns numerous Quartz deposits throughout Quebec

6.          What stage is the company at? 

  • Proof of Concept lab scale testing of Purevap™ validated the disruptive potential in 2016
  • Stage 1 bench metallurgical testing produced nuggets of Silicon Metal (Si) and delivered extensive data for the project design and fabrication of the Purevap Pilot Plant
  • Stage 2 bench testing of scaling up design and process improvements resulting from Stage 1 started, using the Gen 2 Purevap™, a scale version of the Pilot Plant

7.          What are the financial requirements?

  • The Cost to acquire the IP, test, design, build, commission and operate the Purevap Pilot Plant for ten months is $ 8,260,000 to be paid upon milestones between August 2016 and April 2019
  • $5,000,000 (60%) paid or funded to date, leaving a balance of $3,260,000 (40%) to finance

Purevap Process

Latest significant milestones reached during Gen2 testing of the PUREVAP™ Quartz Reduction Reactor


Having a process that uses less feedstock to make 1 MT of Mg Si and allows the substitution of costly high purity Reductant with readily available lower cost material will reduce the cost of making Mg Si, giving that process a competitive advantage, which is what the PUREVAP™ QRR can offer.

As part of the ongoing R&D, PyroGenesis decided to push the envelope of the process by using only one Reductant, a highly reactive carbon source (92.1% Total Carbon) and HPQ off spec SiO2 (98.839% VS 99.83%), Fe2O3 (0.121% VS 0.05%) and Al2O3 (0.182% VS 0.04%) in the Gen2 PUREVAP™ reactor1.

In this test, Gen2 PUREVAP™ produced commercially viable 99.73% Si with 0.166% Fe and 0.0424% Al, representing chemical grade Mg Si2, a product with great commercial value.  By comparison, PyroGenesis calculated that similar material input in a conventional smelter would produce 96.95% Si, a product with little commercial value
