Rio gets Arena support for Yarwun hydrogen plans
The Australian Renewable Energy Agency (ARENA) has announced a A$32.1-million grant for Rio Tinto and Sumitomo Corporation to trial hydrogen calcination technology at the Yarwun alumina refinery in Gladstone, Queensland.
The A$111.1-million Yarwun hydrogen calcination pilot demonstration programme will be the first-of-its-kind deployment of hydrogen calcination in the world. The project is intended to reduce emissions in alumina refining, which currently contributes roughly 3% of Australia’s greenhouse gas emissions.
