Making aluminium smelting observable, predictable and safely flexible.

We develop advanced sensing and control that reveals the real-time state of the Hall-Héroult electrolyte, enabling predictive control and safe demand flexibility in one of the world’s most energy-intensive processes.

Why it matters

Hydropower provides stability today, but interconnections and new large loads such as AI datacentres and semiconductors are tightening long-term capacity margins. Flexibility and predictability are becoming strategic assets. Observability is the foundation: safe change begins with knowing the cell’s true state.

Our technology

Our maintenance-free anodic current-sensor platform synchronously samples current distribution in the HH cell, providing a direct proxy for the electrolyte’s kinetic and thermodynamic state — data not captured by voltage-only monitoring. This unlocks predictive control, safer process adjustments, better component lifetime, and prepares smelters for controlled flexibility.

Process observability Continuous insight into cell behavior; fewer hazardous manual diagnostics.
Predictability and safety Maintain bath parameters, alumina concentration and side ledge integrity while adjusting current.
Grid readiness Prepare for flexibility mechanisms and evolving market or policy signals.
Path to pilots Short paid PoC collaborations to co-create the business case, followed by pilot development with non-dilutive funding.

Collaboration and contact

We are preparing short, paid PoC collaborations with aluminium producers and grid stakeholders to co-create the value and ROI model for flexible smelting, followed by pilot development. We are open to establishing a local presence in Canada as collaborations mature.
