Environmental Impact

We deliver a transformative reduction of carbon emissions for strategic raw materials through an integrated, low‑carbon industrial process.

Our environmental performance is quantified through a Life Cycle Assessment (LCA) based on industrial pre‑FEED data, providing robust and verifiable results across the entire value chain.

Our LCA follows internationally recognized standards (ISO 14040, ISO 14044, ISO 14067) and evaluates emissions from raw materials sourcing through production, logistics, and product delivery. The assessment applies updated industrial assumptions, including energy sourcing, logistics configurations, and allocation methodologies aligned with large‑scale deployment.
 
This approach ensures that carbon footprint reduction is assessed end‑to‑end, avoiding emission transfers between stages of the value chain.

Carbon Footprint Performance

Our process delivers a carbon footprint significantly lower than standard and conventional industrial reference processes, measured in kilograms of CO₂ per kilogram of product across the full value chain.

 
These results reflect the combined impact of low‑carbon production pathways, optimized energy use, and high‑efficiency liquid logistics, avoiding the emission transfers often observed in traditional processes. Based on this LCA, the deployment of HSL’s first industrial plant could enable the avoidance of 700 kilotons of CO₂ by 2032, compared with standard processes.
 
As production capacity scales and additional plants are deployed, cumulative avoided emissions could reach 71,500 kilotons of CO₂ by 2050, driven by the large‑scale substitution of carbon‑intensive silica production routes with HSL’s low‑carbon solution.

Key Drivers of Environmental Performance

Sensitivity analyses identify three primary drivers of carbon performance:

Green silicon sourcing

Electricity mix

Recovered steam utilization

Optimized Energy Use Across the Process

Our environmental performance is rooted in a process designed to minimize energy demand by construction. From production to transport and on‑demand release, HydroSil operates at ambient temperature and pressure, eliminating the need for high‑pressure compression, liquefaction, or cryogenic systems typically required in conventional pathways.

An energy input comparison based on industrial pre‑FEED data shows that HydroSil requires a significantly lower total energy input across the full value chain. In particular, the process avoids the energy‑intensive production steps associated with water electrolysis, which typically require around 55 kWh per kilogram of hydrogen. By integrating material processing and energy generation into a single, optimized solution, HSL reduces cumulative energy consumption, operating complexity, and associated indirect emissions, supporting scalable and durable industrial decarbonization.
