HPQ Silicon Resources (HPQ) has been issued a patent from the United States Patent and Trademark Office.

The patent, titled “Silica to High Purity Silicon Production Process”, covers the PUREVAP^TM Quart Reduction Reactor (QRR) process, which permits a one-step transformation of quartz into high purity silicon metal.

HPQ and PyroGensis Canada Inc. (PYR) have been working together to help produce these materials.

HPQ PUREVAP^TM QRR can not only produce a higher purity silicon material than traditional processes in one step, but it also does not require an “extremely” pure feedstock needed by conventional processes. The process only requires 4.5 tonnes of raw material to make one tonne of silicon, making a 25 per cent reduction in the process. It can potentially allow a 20 per cent cash cost advantage.

Bernard Tourillon, President and CEO of HPQ Silicon, stated,

“The U.S. patent issuance on our novel new approach to making silicon, combined with the end of Q1 start of the GEN3 PUREVAP^TM QRR pilot plant, have culminated at an opportune time, as demand for high purity silicon from the battery and high-performance material companies continues to rise just as bottlenecks, we had foreseen are now occurring in the silicon supply chain.”

High purity silicon is in demand for battery makers and high-value applications manufacturers. It significantly reduced costs, energy input, and carbon footprint compared to traditional processes.

HPQ is a technology company developing hydrogen-based ventures, that could be complementary to its QRR effort and PyroGenesis is a high-tech company working in the design, development, manufacture and commercialization of advanced plasma processes and sustainable solutions which reduce greenhouse gases.

HPQ Silicon Resources Inc. (HPQ) is up 6.45 per cent trading at $0.33 per share as of 12:22 p.m. EST.

PyroGensis Canada Inc. (PYR) is up 6.81 per cent trading at $2.35 per share as of 12:22 p.m. EST.
