MONTREAL, May 10, 2018 – Rio Tinto and Alcoa Corporation today announced a revolutionary process to make aluminium that produces oxygen and eliminates all direct greenhouse gas emissions from the traditional smelting process.

Executives of Rio Tinto, Alcoa and Apple were joined by Canadian Prime Minister Justin Trudeau and Premier of Québec Philippe Couillard for the announcement, which signals the most significant innovation in the aluminium industry in more than a century.

To advance larger scale development and commercialisation of the new process, Alcoa and Rio Tinto are forming ELYSIS, a joint venture company to further develop the new process with a technology package planned for sale beginning in 2024.

ELYSIS, which will be headquartered in Montreal with a research facility in Quebec's Saguenay–Lac-Saint-Jean region, will develop and license the technology so it can be used to retrofit existing smelters or build new facilities.

When fully developed and implemented, it will eliminate direct greenhouse gas emissions from the smelting process and strengthen the closely integrated Canada-United States aluminium and manufacturing industry. The new joint venture company will also sell proprietary anode and cathode materials, which will last more than 30 times longer than traditional components.

Canada and Quebec are each investing $60 million (CAD) in ELYSIS. The provincial government of Quebec will have a 3.5 percent equity stake in the joint venture with the remaining ownership split evenly between Alcoa and Rio Tinto.

Apple is providing an investment of $13 million (CAD). The company helped facilitate the collaboration between Alcoa and Rio Tinto on the carbon-free smelting process, and Apple has agreed to provide technical support to the JV partners.

Rio Tinto and Alcoa will invest $55 million (CAD) cash over the next three years and contribute specific intellectual property and patents.

The patent-protected technology, developed by Alcoa, is currently producing metal at the Alcoa Technical Center, near Pittsburgh in the United States, where the process has been operating at different scales since 2009. The joint venture intends to invest up to $40 million (CAD) in the United States, which would include funding to support the supply chain for the proprietary anode and cathode materials.

Vincent Christ, an experienced leader with more than 30 years' experience at Rio Tinto Aluminium, has been named Chief Executive Officer of ELYSIS.  Most recently, he has served as head of technology, research and development and automation programmes. He holds an engineering degree in electronics and industrial information technology.

Quotes:

"This is a revolutionary smelting process that can deliver a significant reduction in carbon emissions. It builds on the key role aluminium has to play in driving human progress, by making products infinitely recyclable, stronger, lighter and more fuel efficient. Rio Tinto is proud to work with Alcoa, Apple and the governments of Canada and Quebec, to drive an innovation that can transform the industry and our customers' supply chains."

- Rio Tinto chief executive J-S Jacques

"This discovery has been a long-sought goal for the aluminium industry, and this announcement is the culmination of the work from many dedicated Alcoa employees. Today, our history of innovation continues as we take aluminium's sustainable advantage to a new level with the potential to improve the carbon footprint of a range of products from cars to consumer electronics."

- Alcoa President and CEO Roy Harvey

"Today's announcement will create and maintain thousands of jobs for Canadians, significantly reduce Canada's carbon footprint, and further strengthen the aluminium industry in North America. It is a truly historic day for the aluminium industry – and for all Canadian aluminium workers – who play such an important role in our economy and our country's future."

- Prime Minister of Canada Justin Trudeau

"With the establishment of this new facility, Québec will continue to lead the world in the development of advanced aluminium smelting technologies. Our investment will play a key role in the large-scale development of this carbon-free aluminium smelting technology, so it can be deployed and deliver significant environmental benefits with well paid, highly skilled jobs here in Québec."

- Premier of Québec Philippe Couillard

"Apple is committed to advancing technologies that are good for the planet and help protect it for generations to come. We are proud to be part of this ambitious new project, and look forward to one day being able to use aluminium produced without direct greenhouse gas emissions in the manufacturing of our products."

- Apple CEO Tim Cook

About ELYSIS

Our name refers to the process at the center of aluminium smelting, the electrolysis of alumina. It's a tribute to our history, but it indicates a fundamental change that will be known as the ELYSIS process.ELYSIS will directly employ 100 people, including research and development, management and sales.At the ELYSIS facility in Québec, employees will work on the commercialisation of the world's first zero-carbon aluminium smelting technology.In Canada, the technology could eliminate the equivalent of 6.5 million metric tonnes of greenhouse gas emissions, if fully implemented at existing aluminium smelters in the country. That represents an amount roughly equal to taking nearly 1.8 million light-duty vehicles off the road.
