HPQ Silicon issued U.S. patent for PUREVAP™ Quartz Reduction Reactor technology

HPQ Silicon Resources Inc., an innovative silicon solutions and technology development company, has informed that the United States Patent and Trademark Office issued U.S. Patent No. 11,267,714 entitled “SILICA TO HIGH PURITY SILICON PRODUCTION PROCESS” to Company on March 8 2022.

The US patent covers the PUREVAP™ Quart Reduction Reactor (QRR) innovative process, which permits the one-step transformation of quartz (SiO2) into high purity silicon metal (up to 4N+ Si), the material sought after by battery makers and high-value application manufacturers, at significantly reduced costs, energy input, and carbon footprint than traditional processes.

HPQ PUREVAP™ QRR disruptive advantages mean that not only can it produce a higher purity silicon material than traditional processes in one step, but it also does not require the extremely pure feedstock needed by conventional processes. In fact, the process only requires 4.5 MT of raw material to make 1 MT of Silicon, versus the 6 MT required by conventional processes, a 25% reduction which potentially allows a 20% cash cost advantage versus the lowest cost traditional Silicon producer1.

Since 2015, HPQ PUREVAP™ QRR has been at the forefront of disrupting Silicon manufacturing, an industry that still relies on a traditional process to make silicon first develop in 1899. The U.S. patent issuance on our novel new approach to making silicon, combined with the end of Q1 start of the GEN3 PUREVAP™ 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. With ESG principles playing an active role in materials sourcing, the world is more aware of the difficulties of securing the ESG compliant Silicon needed to meet its renewable energy goals. The reality of chronic underinvestment in new technologies combined with the offshoring of Silicon production capacity, has created a massive opportunity for HPQ and its PUREVAP™ QRR patented process, as we are the only company to bring to market a new process for making Silicon that is perfectly suited to the new demands and realities of the Silicon market,” said Mr. Bernard Tourillon, President and CEO of HPQ Silicon.
