HPQ Silicon Inc., headquartered in Montréal, Quebec, is a leading provider of advanced silicon and silica materials engineered for sustainable applications across global industries, including electric vehicle (EV) batteries and clean energy systems. The company specializes in developing high-purity silicon products using its proprietary PUREVAP™ Technology—a one-step manufacturing process designed to minimize environmental impact while achieving exceptional material quality.
HPQ’s core mission is to supply next-generation materials critical to industries transitioning to low-carbon technologies, with a particular focus on addressing the growing demand for silicon in lithium-ion batteries. By integrating innovation with sustainability, HPQ positions itself as a key player in advancing eco-friendly production methods aligned with net-zero goals. Its global reach includes innovative partnerships and a state-of-the-art laboratory in Solaize, France, operated by its affiliate NOVACIUM SAS.
Battery Technology
HPQ Silicon’s advancements in battery-related materials are centered on enhancing energy storage efficiency through silicon-based solutions. The company’s GEN3 silicon-anode material demonstrates a significant 30% improvement in cumulative energy return over 650 cycles compared to traditional graphite anodes, enabling higher-capacity batteries with faster charging capabilities. This innovation is driven by HPQ’s PUREVAP™ Quartz Reduction Reactors, which produce silicon at purities ranging from 2N+ to 4N while eliminating CO₂ emissions and reducing costs. Beyond anodes, HPQ has pioneered a process for manufacturing fumed silica—an additive critical for improving battery stability and performance—via its proprietary FUMED SILICA REACTOR.
Collaborations with key partners, such as NOVACIUM’s development of silicon oxide (SiOx)-based anode materials and a project with the French Army to create ultra-high-capacity batteries for military applications, further underscore HPQ’s commitment to industry-relevant innovation. These silicon-based solutions are designed to seamlessly integrate into existing battery supply chains, offering scalability without major infrastructure overhauls. The company is also advancing a patented process to produce silicon suboxide (SiOx), a precursor for next-generation anodes, and pursuing fumed alumina and titanium oxides for battery cathodes, broadening its footprint in the lithium-ion ecosystem.
Recent Projects
In early 2025, HPQ achieved several milestones, including the successful pilot production of fumed silica using its Fumed Silica Reactor (FSR), positioning the company to become Canada’s first domestic supplier of the material by Q4 2025. Concurrently, tests showed GEN3 silicon-anode batteries exceeding 900 cycles with a 31% cumulative energy gain versus graphite benchmarks. HPQ secured a patent for a one-step method to produce fumed alumina and titanium oxides for battery cathodes, while NOVACIUM filed a provisional patent for converting aluminum waste (black dross) into reusable materials—a breakthrough advancing circular manufacturing. Additionally, HPQ bolstered its stake in NOVACIUM to 28.4%, reinforcing strategic collaboration to further battery technology development.
Investors
HPQ Silicon’s equity stakeholders include Institutional investors like Investissement Québec, holding approximately 8.7% of basic shares. Management and board members collectively own between 6.3% (basic) and 10.7% (fully diluted). Notable individual shareholders include CEO Bernard Tourillon (2.909%) and other executives. Strategic investors account for roughly 7.0% of basic shares. Key partners in technology development include PyroGenesis Canada Inc. and NOVACIUM SAS, which are integral to scaling HPQ’s innovations.
