Key performance drivers

Three Levers. Measurable Outcomes.

01
Current Efficiency

Higher current efficiency increases metal output without increasing amperage. MetSol technologies improve:

  • Pot stability
  • Alumina feed precision
  • Heat and mass balance
  • Current distribution
  • Cathode performance
02
Power Consumption

Electricity is one of the largest cost drivers in primary aluminium production. MetSol solutions reduce specific energy consumption by:

  • Lowering operating voltage
  • Reducing cathode voltage drop
  • Minimising anode effects
  • Improving alumina dissolution and distribution
03
Environment

Reducing carbon intensity is now both a strategic and regulatory priority. MetSol technologies support:

  • Lower PFC emissions through anode-effect suppression
  • Reduced Scope 2 emissions through lower energy use
  • Lower carbon footprint per tonne of aluminium
  • Improved ESG reporting
  • Alignment with Green Aluminium objectives
Green Aluminium

APC+™ directly reduces anode effects and PFC emissions through advanced feed control and predictive suppression.

Integrated strategy

A Practical Path to Lower Carbon Intensity

Lower specific energy consumption directly reduces Scope 2 emissions in carbon-intensive grids — without major rebuilds or large capital projects.

01
Optimise pot control
APC+™ reduces operating voltage and stabilises heat balance in real time
02
Improve alumina distribution
MPF™ reduces local depletion and suppresses anode effects
03
Upgrade cathode and anode hardware
HPCA™ and HPAA™ cut resistive losses and extend pot life<
Up to 820 kWh/t combined energy savings potential

Each MetSol technology targets a specific energy-loss pathway in the reduction cell. Deployed together, they address the full stack — from process control logic to physical hardware — delivering compounding improvements across the potline.

No structural rebuilds. No new potlines. MetSol solutions integrate with existing infrastructure, making improved performance accessible on legacy smelter technology as well as modern installations.

The result is a practical pathway to lower carbon intensity that meets the requirements of carbon reporting frameworks, green product certification, and long-term ESG commitments.
