(“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: O08), a technology company specializing in green engineering processes for silica and silicon material production, is pleased to provide shareholders with an update on the PUREVAPTM Gen3 Quartz Reduction Reactor ("Gen3 QRR”) project being developed in partnership with technology provider PyroGenesis Canada Inc. (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY) (“PyroGenesis”).
The most recent results from our continuous testing have achieved the highest Silicon purity level recorded to date, reaching 99.96%. This milestone signifies the successful removal of an additional 400,000 parts per billion (PPB) of impurities compared to our previous record of 99.92% purity. The achievement brings us one step closer to our goal, making the production of 4N Silicon in a single step not only feasible but within our grasp.
WITH EACH TEST: HPQ GEN3 QRR IS DELIVERING HIGHER PURITY LEVELS IN A SINGLE STEP
Silicon material produced during tests #6 was sent for ICP-MS Silicon Bulk Sample Analysis at Air Liquide Electronics (Balazs NanoAnalysis), and the results delivers a record 99.96% (3N+) Silicon Bulk Purity, outperforming test #5 results of 99.92%.
The key trend emanating from the Gen3 QRR testing to date and the silicon purity results are:
- Reproducibility of the one step production of Silicon that exceeds the highest purity threshold (2N) of commercially available silicon material, and
- Reproducibility of the one-step production of Battery Grade Silicon (3N+), the purity required for feedstock in the manufacturing of Silicon Base anode material, and
- Reproducibility of the production of silicon using 25% less feedstock than conventional carbothermic processes that use a ratio of 6 tonnes (t) of raw materials to produce 1 t of metallurgical grade silicon (MG Si – 98.5% to 99,5%) [1].
“The reproducibility of the results obtained by Gen3 QRR is another demonstration of how HPQ PUREVAPTM QRR process is modernizing the production of high-purity Silicon, transforming a century-old industrial process known for its significant CO2 emissions into an efficient, scalable, and low carbon manufacturing process," stated Bernard Tourillon, President & CEO of HPQ Silicon. "With Silicon now officially included in the US Department of Energy (DOE) 2023 Final Critical Materials List [2], the timing for the advancement of our Purevap project could not be better."
Over the past year, HPQ's three key initiatives – Silicon, Fumed Silica, and Autonomous Hydrogen Generation via Hydrolysis – have achieved significant milestones as we diligently executed our business plan.
HPQ SILICON INITIATIVE:
The demand for silicon is projected to surpass 3.8 million tonnes, valued between US$15 billion and US$20 billion, by 2025 [3]. These numbers do not take into consideration the 300,000 t of Silicon-based anode material demand projected by 2030, representing another market estimated to be worth about US$ 15 billion [4] that will need 3N+ Silicon as feedstock.
The conventional silicon manufacturing processes, with purity ranging from 98.5% to 99.5%, are 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. This information is based on the Intergovernmental Panel on Climate Change (IPCC), a United Nations body dedicated to climate change research [5].
HPQ is advancing its exclusive PUREVAPTM Quartz Reduction Reactor (QRR) technology, introducing a novel, compact, modular process that produces silicon with zero CO2 emissions. This innovation employs 25% less feedstock compared to traditional methods [6].
At the core of the PUREVAPTM QRR lies its Closed Electric Arc Furnace (CEAF) design, designed to operate under precisely controlled atmospheric conditions. This cutting-edge furnace allows the semi-continuous input of Silica (SiO2) and a carbon reductant, streamlining the production of 3N+ silicon in a single step. Importantly, the QRR's design ensures efficient capture of the CO gas (“Co(g)”) generated during the carbothermic reaction, enabling its potential for further utilization.
Investors are invited to explore the HPQ Silicon website and access our latest presentation, providing an elaborate insight into our development strategy for our three key initiatives, including their indicative short, medium, and long-term developmental steps.
We are delighted to present the immediate development milestones for our PUREVAPTM QRR project:
- Successful completion of a Silicon pour.
- Achievement of one-step production of 4N Silicon.
- Commencement of commercial operations with six continuous production cycles daily, yielding 20 kg of Silicon per pour.
- Validation of QRR's capacity to produce up to 4N+ Si higher conversion efficiency of 75% compared to 50-60% with the conventional way [6].
- Initiation of crucial engineering studies for the future Gen4 PUREVAPTM - a 2,500 TPY system.
- Production of Silicon materials for HPQ Silicon's anodes initiative.
- Securing grant financing for proof-of-concept studies concerning HPQ Green Silicon capability.
- Launch of proof-of-concept studies for HPQ Green Silicon initiative. Centered on the capture of CO gas generated during direct carbothermic production of silicon from quartz and convert it to solid carbon that can be re-injected in the next production cycle [7].
