Innovative recovery of valuable raw materials from ‘red mud’

Waste slags from the metallurgy industries often contain valuable materials, but in very small concentrations. This means that large areas of valuable land are used to accommodate reservoirs filled with what is sometimes toxic waste. We now want to use hydrogen to convert this waste into a resource.

Hydrogen production and carbon capture – in a single step

A team of Norwegian researchers has succeeded in producing hydrogen using a far more efficient method than is currently in use. The technology was ready as early as in 2017. The team has also demonstrated that the process can be scaled up for commercial application.
