Carbon capture is cheaper than ever
According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.
Could the chloride process replace the Hall-Héroult process in aluminium production?
At present, the Hall-Héroult process is universally used in the production of aluminium. It is an electrolytic process in which aluminium oxide is dissolved in molten cryolite (Na3AlF6) and then reduced electrolytically to aluminium at a temperature of around 960°C. The process uses carbon anodes that are consumed during the electrolysis, forming CO2. Aluminium oxide (alumina) is produced from bauxite, an alumina-rich clay mineral, by means of the Bayer process.
New Gemini centre gives greater clout to developing hydrochemical process technology
SINTEF Industri, NTNU and UiO, three partners in the new Gemini Centre HyProS “Hydrochemical process technology in the circular economy”, kicked off the new venture from Herøya Industrial Park last week.

Is aluminium electrolysis using inert anodes a blind alley?
The Hall-Héroult process, patented in 1886, is currently used universally for the smelting of primary aluminium. Since then, of course, many improvements have…
