Hydro announced on October 19, 2026, that it had produced aluminium using its HalZero electrolysis technology for the first time at its research and test facility in Herøya, Porsgrunn, Norway. Enova also awarded close to NOK 82 million for concept development and planning of an industrial pilot. For OEM buyers, the announcement marks progress in primary aluminium research; it does not create a near-term supply of zero-emission aluminium or change current material procurement requirements.
Hydro Produces First Metal from Aluminium Chloride at Herøya
The Herøya team produced metal from aluminium chloride, validating a step in a process Hydro has been developing since 2016. The work involves Norwegian research institutions NTNU and SINTEF. Hydro's existing test center has operated since January 2026 and allows technologists to test individual process steps before attempting a more integrated pilot.
Hydro CEO Eivind Kallevik called the first metal an important milestone for the company and its research partners. The company also attached a clear qualification: several years of targeted testing and piloting remain before HalZero could be ready for industrial use.
| Development stage | Status after the announcement | Purpose |
|---|---|---|
| Current Herøya test facility | First metal produced from aluminium chloride | Test individual process steps and build operating knowledge |
| Industrial Concept Pilot | Concept development and planning funded | Integrate the required process steps under conditions closer to industrial operation |
| Industrial deployment | Still requires further development and investment decisions | Assess technical performance, scale-up, and commercial viability |
HalZero Targets Closed-Loop Chlorine and Carbon Use
Most primary aluminium is produced through the Hall-Héroult process, in which oxygen from alumina reacts with carbon anodes and generates CO2. HalZero takes a different route. Alumina is converted into aluminium chloride before electrolysis, with chlorine and carbon designed to remain in closed loops.
Hydro's long-term objective is to eliminate CO2 emissions from electrolysis and anode production while releasing oxygen. That objective describes the intended completed process. Hydro states that production at the current test stage still generates CO2 emissions, so the first metal cannot be presented as verified zero-emission commercial aluminium.
NOK 82 Million Funds Planning for an Industrial Concept Pilot
Enova, a state enterprise owned by the Norwegian Ministry of Climate and Environment, awarded close to NOK 82 million for the next development phase. The funding supports a feasibility study, concept development, and planning for an Industrial Concept Pilot in Grenland.
The planned facility would be larger than the existing test center and would bring the main process steps together. This integration is important because a sequence that works in separate tests still has to demonstrate stable operation as a complete process.
The grant does not constitute a decision to build the pilot. Hydro said any future realization depends on technology development, project completion, and subsequent investment decisions. SMM independently reported the same funding amount and confirmed that the award does not represent construction approval.
HalZero Remains Years from Industrial Deployment
- No immediate supply change. The milestone is confined to a research and test facility. Buyers should not interpret it as a new commercial aluminium source or an immediate change in availability.
- Process integration is the next technical gate. The proposed pilot would test how the individual steps operate together, providing evidence needed for later scale-up assessments.
- Carbon claims need a defined boundary. Current testing still emits CO2. Future claims will need verified operating data that distinguish electrolysis, anode production, energy supply, and the wider product footprint.
- Commercial performance remains open. The announcement provides no validated production cost, capacity, or delivery data. Those questions belong to later pilot and investment evaluations.
For procurement teams, the practical response is to track the technology while keeping current specifications grounded in available alloys, documented recycled content, energy-related data, and supplier traceability. HalZero is relevant to long-term roadmaps, but present purchasing decisions still require present production evidence.
Meituo Tracks Material Innovation Alongside Current Production Needs
Meituo's current work centers on verified production inputs and controlled processing. Our aluminum die casting operations use A380 and ADC12 alloys with batch-level spectroscopic analysis, supported by machining and inspection for OEM components. Through our sustainable manufacturing systems, we also manage environmental data and resource efficiency. Customers reviewing material requirements can contact our team to discuss alloy selection, casting design, machining, and documentation for current programs.
