For more than 80 years, the fumed silica industry has relied on conventional production methods built around silicon tetrachloride. HPQ Silicon believes its Fumed Silica Reactor offers a different route: producing commercial-grade fumed silica directly from quartz.
That is why Bernard Tourillon’s latest interview matters. HPQ’s July 8, 2026 press release confirmed that the pilot program achieved its two principal objectives: reliably producing commercial-grade fumed silica directly from quartz and generating the engineering and operating data required to support the design, costing and economic evaluation of future commercial production facilities.
But the interview added the bigger investor context: pilot success did not narrow HPQ’s path. It expanded the commercial conversation.
WHAT YOU NEED TO KNOW
Pilot Validated: HPQ says the pilot program demonstrated that the FSR can produce commercial-grade fumed silica directly from quartz, including pilot-scale production of commercial-grade “150” fumed silica.
Engineering Confidence: PyroGenesis completed a detailed engineering review of pilot operating data, which HPQ says strengthened confidence in projected operating parameters and commercial-scale economics.
Commercial Discussions Expanded: HPQ had previously announced a non-binding MOU for a proposed 1,000 tonne-per-year commercial plant, but Bernard said the opportunity has now become broader than that original framework, with discussions involving new groups, old groups and parties that were already under NDA.
Evonik Question Addressed: Bernard addressed investor questions directly, saying they remain involved, communications have not stopped and the company had asked HPQ to be more discreet in how often its name was used publicly.
Multiple Deployment Paths: HPQ’s strategy includes joint ventures, licensing opportunities, royalty-based production partnerships and company-owned production facilities where appropriate.
PyroGenesis Transaction Advancing: HPQ and PyroGenesis remain in the final stages of completing the previously announced transaction under which PyroGenesis would acquire a 50% ownership interest in HPQ Silica Polvere while remaining the exclusive equipment supplier for commercialization.
STRATEGIC IMPLICATIONS
The interview clarified why HPQ’s original timeline around the non-binding MOU shifted. Bernard did not frame the delay as a lack of interest. He framed it as the result of a broader opportunity set that requires more commercial, legal and technical work before HPQ commits to a structure.
That distinction matters. HPQ had previously anticipated completing negotiations related to the initial non-binding MOU by the end of the second quarter of 2026. Since then, according to the company, successful pilot completion, independent validation and greater confidence from the engineering review have expanded the market opportunities and strategic partnerships being evaluated.
Bernard’s key message was that HPQ now has a better understanding of what the technology could look like at scale, including cost structure and potential price points. That has given the company more confidence to re-engage with existing parties, speak with new potential industrial participants and evaluate multiple possible commercial structures.
He also explained why fumed silica commercialization requires a more deliberate process than HPQ’s battery materials business. Fumed silica is an industrial material used in large-volume markets, which means potential partners need to understand scale, logistics, packaging, sales channels, financing and long-term supply before committing.
On PyroGenesis, Bernard said the commercial arrangement is clear: PyroGenesis gives up its lifetime royalty in exchange for 50% ownership of HPQ Silica Polvere. The remaining work is largely tied to legal, accounting and shareholder agreement matters. He also said a future spinout remains possible, but would be a joint discussion between the owners once the transaction is completed.
CEO Bernard Tourillon:
“The pilot program has demonstrated that our Fumed Silica Reactor can produce commercial-grade fumed silica directly from quartz and generated the engineering data required to evaluate multiple commercial pathways with significantly greater confidence. The pilot program has transformed the FSR from an engineering development project into a scalable industrial platform supported by independent validation, strengthened engineering confidence, and growing interest from potential industrial participants. Our focus is selecting the optimal deployment strategy while positioning the FSR as a scalable platform capable of serving multiple industrial markets and creating sustainable long-term shareholder value.”
INVESTOR TAKEAWAY
HPQ Silicon’s fumed silica story is no longer just about proving that the FSR can make commercial-grade material. According to the company’s July 8 update, the pilot program demonstrated commercial-grade fumed silica production directly from quartz and produced the engineering data needed to evaluate future commercial deployment.
The interview added the context investors needed. Bernard explained that the opportunity has expanded beyond the original non-binding MOU because HPQ now has more pilot-scale data, greater confidence in cost structure and a broader view of where the technology may fit commercially. He also made clear that discussions remain active with multiple parties, including Evonik, the original LOI party, while HPQ evaluates which business structure best protects long-term shareholder value.
The most important point is that HPQ has not announced a definitive commercial project. Management is still negotiating, evaluating structures and completing the technical, commercial and legal work required to move forward. The company also cautioned that there can be no assurance that definitive agreements will be executed or that any proposed commercial project will ultimately proceed.
For investors, the story has shifted from “does it work?” to “what is the right deal?” With pilot validation complete, engineering confidence strengthened and strategic discussions expanded, HPQ is now focused on selecting the deployment path it believes can maximize the long-term value of the FSR technology.
