HPQ Silicon Inc.

HPQ Silicon Inc. is a Quebec-based technology company dedicated to innovation in advanced materials and critical process development. Headquartered in Montreal, Canada, the company's core mission is to develop green engineering processes for the production of silica and silicon materials, contributing to the global transition towards net-zero emissions.

The company's portfolio includes several key technologies. It is developing the PUREVAP™ Quartz Reduction Reactor (QRR) for the one-step transformation of quartz into high-purity silicon metal, and the PUREVAP™ Fumed Silica Reactor (FSR) which produces commercial-grade fumed silica directly from quartz. Additionally, HPQ Silicon focuses on engineered silicon-based anode materials (Gen3) for lithium-ion batteries, commercializing its ENDURA+ lithium-ion cells, and advancing clean-hydrogen and waste-to-energy technologies. These solutions are designed to serve critical sectors such as energy storage, consumer products, data centers, and industrial hydrogen.

Under the leadership of Chairman, President, and CEO Bernard J. Tourillon, HPQ Silicon is actively transitioning from technology development to commercialization. Recent developments include advancing the deployment strategy for its Fumed Silica Reactor technology, with successful pilot programs expanding market opportunities as of July 2026. In June 2026, the company signed a Letter of Intent to explore the development of a Canadian-based electric propulsion platform for North American markets, positioning its ENDURA+ battery platform for applications in drones and autonomous systems. HPQ Silicon aims to become a low-cost, zero-CO₂ producer of fumed silica and high-purity silicon.
