Rio Tinto and Sumitomo Corp look at hydrogen pilot for Yarwun refinery

Rio Tinto and Sumitomo Corporation have announced a partnership to study the construction of a hydrogen pilot plant at Rio Tinto’s Yarwun alumina refinery in Gladstone, Australia, and explore the potential use of hydrogen at the refinery.

The two global companies have signed a letter of intent that focuses on Yarwun as the location for a Gladstone hydrogen plant that Sumitomo has been studying. If the project proceeds, the pilot plant would produce hydrogen for the recently announced Gladstone Hydrogen Ecosystem, Rio said.

The study supports the efforts of Australian, Queensland and local governments to establish Gladstone as a clean hydrogen hub of the future, according to the company.

Rio Tinto Australia Chief Executive, Kellie Parker, said: “Rio Tinto has a long relationship with Sumitomo and we are delighted to partner with them to explore the possibilities of hydrogen, not only for our own refinery, but for Sumitomo to supply industry more broadly in Gladstone.

“Reducing the carbon intensity of our alumina production will be key to meeting our 2030 and 2050 climate targets. There is clearly more work to be done, but partnerships and projects like this are an important part of helping us get there.”

Sumitomo Corporation’s Energy Innovation Initiative Director, Hajime Mori, said: “We are excited about working together with Rio Tinto as our long-term partner to develop this hydrogen project in Gladstone and working toward our company’s vision of achieving carbon neutrality by 2050.

“We believe the pilot plant will play a significant role in establishing the Gladstone Hydrogen Ecosystem.

“Sumitomo has commenced the Design Study and Preliminary Master Planning to build the Gladstone hydrogen ecosystem and we will continue to work towards future hydrogen exports from Gladstone.”

Deputy Premier and Minister for State Development, Steven Miles, said Gladstone is an industrial powerhouse and this partnership presents a great opportunity for the region and for Queensland.

“This is only the beginning of a wave of international collaborations that will lead to new industries and new jobs underpinned by the supply of renewable energy,” Miles said.

“With the Palaszczuk Government’s strong commitment to creating more jobs in emerging industries, we will work to keep Queensland at the forefront of renewable hydrogen and the opportunities that come with it.”

The Sumitomo partnership complements a recently announced feasibility study into using hydrogen to replace natural gas in the alumina refining process at Yarwun and provides the potential for larger-scale implementation if the studies are successful, Rio added.
