Rio Tinto and Carbfix have entered into a partnership to apply carbon collection technology and its permanent storage underground at the ISAL aluminum smelter in Iceland, Rio Tinto announced today.
The partnership was established, as stated, with the aim of supporting the further decarbonisation of aluminum production and the fight against climate change.
It is explained that Carbfix technology accelerates natural processes and transforms carbon dioxide injected into geological formations into solid carbon minerals.
The raw materials used in this process are water, electricity and a favorable substrate such as basalt that surrounds the ISAL site in Iceland.
In accordance with the Memorandum of Understanding on Strategic Partnership, Carbfix will use Rio Tinto’s land in the vicinity of the ISAL smelter, for the world’s first carbon mineral storage center, called the CODA Terminal.
Liquid carbon dioxide will be brought by ship for storage from industrial sites across Northern Europe.
Rio Tint believes that ISAL is the ideal location for the first smelter in the aluminum industry, where carbon collection and storage will be carried out in a safe and economical way.
The two companies will work together to improve carbon collection solutions, and some of them are already being tested in production units at the ISAL smelter, with the aim of applying Carbfix technology to further decarbonize the plant.
“Global goals in the fight against climate change cannot be achieved without the widespread use of carbon capture and storage. The partnership with Rio Tinto will allow Carbfix to make great strides in the development of the world’s first carbon mineral storage center, thanks to which our technology would make a significant contribution. global efforts to combat climate change, “said Carbfix CEO Eda Sif Aradotir.
Rio Tinto Aluminum CEO Ivan Vela said the innovative technology developed by Carbfix paves the way for further decarbonisation of aluminum production at the ISAL smelter, which already produces low-carbon aluminum using renewable energy.
“We will work together to address technical challenges to advance carbon storage solutions. In addition, we will seek opportunities for the wider application of Carbfix decarbonization technology in Rio Tinto operations, complementing other innovations such as our ELYSIS zero-carbon partnership in aluminum smelting.” he said.
All guidelines of the Interstate Panel on Climate Change, which aims to limit global warming to 1.5 degrees Celsius, require serious reductions in harmful gas emissions and include technologies for reducing the share of carbon dioxide, Rio Tinto stated.
It was pointed out that Rio Tinto’s priority remains to reduce harmful gas emissions in mines and smelters, while the company is at the same time exploring the potential role of carbon storage and mineralization.
Carbfix plans to prepare the first injection wells for the KODA terminal in 2022, and carbon dioxide deliveries are expected in 2025.
