Ambitious proposals for surplus electricity once Tiwai closes

Kathryn Ryan speaks with two scientists about how electricity from the Manapouri power station could be used once the Tiwai Point aluminum smelter is shut down by Rio Tinto next August.

The smelter currently uses 13 per cent of the country’s power production. The McDiarmid Institute says there are many options including manufacturing silicon solar panels, turning electricity into hydrogen and developing energy storage.

Otago University Chemistry professor Professor Sally Brooker and Principal Investigator in the MacDiarmid Institute for Advanced Materials and Nanotechnology, and Auckland University emeritus professor of Chemical sciences, David Williams.
