  • Up to 92.0% less energy is required to produce fumed silica in one step compared to conventional industry processes

  • Up to 99.9% less CO2 emissions associated with the production process compared to conventional industry processes.

MONTREAL, Aug. 15, 2024 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), a technology company specializing in the green engineering of silica and silicon-based materials is pleased to share new data from recent updated process modelization work. This work was accomplished by technology supplier PyroGenesis Canada Inc. (TSX: PYR, OTCQX: PYRGF, FRA: 8PY) (“PyroGenesis”) during the ongoing commissioning of HPQ Silica Polvere Inc. (“HSPI”) [1] Fumed Silica Reactor (“FSR”) pilot plant.

The new data highlights the commercial and environmental impact advantages of the HSPI Fumed Silica project compared to conventional industry processes.

Reducing Energy Use and Carbon Footprint in Fumed Silica Production

Since the project's inception in July 2021, our working models have consistently been based on the estimate that producing 1 kg of fumed silica at commercial scale using the FSR would require between 10 and 15 kWh [2] of energy experimentally compared to 4-5 kWh theoretically based on the thermal model developed by PyroGenesis. This assumption has been the foundation of our internal technical and economic study, published on January 10th, 2024, which demonstrated the strong commercial potential of the FSR, as well as the update released on June 5th, 2024.

As part of the current commissioning work, data collected from updates to the thermal model now indicate that the energy required to produce 1 kg of fumed silica at commercial scale of at least 1,000 TPY has been reduced to a range of 8 to 12 kWh [3]. This represents an additional 20% reduction in the energy requirements for the FSR project which is due to an optimized thermal efficiency of the process.

The updated model indicates that HSPI FSR technology requires 92% less energy when compared to conventional processes, which typically consume between 100 and 120 kWh per kg of fumed silica produced [4].

The additional 20% reduction in energy requirements significantly enhances the environmental benefits of the FSR project. Since energy consumption and its associated greenhouse gas (GHG) emissions account for approximately 99% of the carbon footprint of FSR technology, this reduction is crucial. When factoring in the updated model data and considering that energy production in Quebec generates 1.7 grams of CO2 equivalent per kWh, the HPSI FSR technology should now emit only 0.0136 kg of CO2 per kg of fumed silica produced [5].
