Developing Processes For The Low-Cost Manufacturing Of High Purity Silicon Metals For Next-Generation Lithium-ion Batteries

Achieved final critical milestones, completing a successful silicon pour

Message: VIDEO – HPQ On The Cusp Of Transforming 120 Year Old Process of High Purity Silicon Production

Silicon is the 2nd most abundant element on the planet yet silicon metal manufacturing is currently the largest emitter of CO2 Among Metals And Non-Ferrous Metals on a per ton basis.


The demand for silicon is projected to surpass 3.8 million tonnes, valued between US$15 billion and US$20 billion, by 2025. By 2030 Silicon-based anode material demand estimated to be worth about US$ 15 billion that will need 3N+ Silicon as feedstock.



The conventional silicon manufacturing processes, both expensive and energy intensive. The process, invented in 1899, is still utilized today, making Silicon production the largest CO2 emitter among all metals and non-ferrous metals. HPQ  PUREVAP Quartz Reduction Reactor (QRR) technology is a revolutionary, compact, modular process that produces silicon cheaper & with zero CO2 emissions.


More than just lip service, HPQ testing has delivered the highest ever purity levels from a one-step process:

  • Reaching 99.96% (3N) Purity
  • Successful removal of an additional 400,000 parts per billion of impurities 
  • One step closer to goal of 4N Silicon in single step not only feasible but within company’s grasp

Earlier today HPQ Silicon Inc. Provided an exciting update. 


Major Milestones Achieved 

HPQ has already successfully reached 80% completion of key project milestones, including:

  • Achieving an astounding 99.5% silicon purity (2N+), surpassing industry standards.
  • Scaling up production by a mind-boggling 2,500 times from PUREVAP™ Gen2 QRR.
  • Demonstrating the semi-continuous batch production capability of the reactor.
  • Achieving one-step production of 3N+ Silicon, meeting the stringent requirements for battery-grade Silicon.
  • Using 25% less feedstock compared to traditional carbothermic processes, making it not only efficient but eco-friendly.

Innovation and Progress 

With PyroGenesis Canada Inc. (TSX: PYR) making crucial upgrades, including enhancing the Gen3 QRR design and crucible improvements, the stage is set for a successful silicon pour, slated to happen soon. This will mark a significant turning point in the silicon industry.


Green and Sustainable Future 

HPQ Silicon Inc. is not just a company; it's a catalyst for change. By reducing CO2 emissions and offering scalable, low-carbon manufacturing processes, they are leading the way towards a sustainable future.


Future Potential 

The demand for silicon is set to soar, and HPQ's technology positions it to play a pivotal role in the $15 billion silicon market by 2025 and the $15 billion Silicon-based anode material market by 2030.


Beyond QRR 

HPQ has a multi-pronged approach, with exciting developments in Fumed Silica and Autonomous Hydrogen Generation via Hydrolysis. These projects are making significant strides, offering investors diversified opportunities for growth.


What's Next? 

While we anticipate the successful silicon pour, remember that HPQ Silicon Inc. has multiple projects in motion, and each one is a stepping stone toward innovation and success.
