Hydro and Rio Tinto have forged a partnership to develop and assess carbon capture technologies for aluminum smelters. This alliance aims to accelerate decarbonization within the aluminum industry.

Joint Research and Development Initiatives

The agreement entails shared research and development costs, laboratory test results, and on-site pilot program data. The goal is to create commercially viable carbon capture technologies. The companies will invest roughly $45mn over five years, conducting work at Hydro's Norwegian facilities and Rio Tinto's European assets. Both companies will continue independent decarbonization efforts. A key focus will be anode consumption, representing 75pc of a smelter's direct carbon emissions. Hydro's HalZero smelting process and Rio Tinto's Elysis joint venture with Alcoa are central to this research.

Accelerating Technology Development

"The current technology readiness level is low and requires significant development efforts to mature from laboratory to commercial scale," the companies stated. The collaboration aims to expedite this development to reduce greenhouse gas emissions from smelters.
