Company Overview

HPQ Silicon Inc., headquartered in Montréal, Quebec, is a leading provider of advanced silicon and silica materials engineered for sustainable applications across industries such as EV batteries and clean energy systems. The company uses its proprietary PUREVAP™ Technology to manufacture high-purity silicon products in a one-step process that minimizes environmental impact. HPQ’s mission is to supply next-generation materials critical for low-carbon technologies and support industries transitioning to net-zero goals.

Battery Technology

HPQ Silicon’s core technology centers on its PUREVAP™ Quartz Reduction Reactors, which produce silicon at purities from 2N+ to 4N with zero CO₂ emissions, and its Fumed Silica Reactor for manufacturing fumed silica additives. The company also develops processes for silicon suboxide (SiOx), fumed alumina, and titanium oxides for battery cathodes to enhance energy storage efficiency.

Products

Key products include the GEN3 silicon-anode material offering a 30% improvement in energy return over 650 cycles, fumed silica produced via the Fumed Silica Reactor, silicon suboxide (SiOx) precursors, and fumed alumina and titanium oxides for battery cathodes.

Recent Projects

In 2025, HPQ pilot-produced fumed silica to become Canada’s first domestic supplier, demonstrated GEN3 batteries exceeding 900 cycles with a 31% energy gain, secured a patent for a one-step fumed alumina and titanium oxides process, saw NOVACIUM file a provisional patent for aluminum waste conversion, and increased its stake in NOVACIUM to 28.4%.

Investors

Investissement Québec holds 8.7% of the company. Management and board members collectively own between 6.3% and 10.7%. CEO Bernard Tourillon owns 2.9%. Strategic investors hold 7%. Key partners include PyroGenesis Canada Inc. and NOVACIUM SAS.
