Orica says it has achieved another milestone in its decarbonisation journey, eliminating the first 250,000 t of carbon dioxide equivalent (CO2-e) from its Kooragang Island manufacturing facility with an Australian first deployment of tertiary catalyst abatement technology (pictured).

The installation of three tertiary abatement reactors at its Kooragang Island facility has eliminated the equivalent of 20% of the plant’s total greenhouse gas emissions, for the period from November 2022 to August 2023. This means that for every tonne of nitric acid produced at the facility to produce products for many businesses across New South Wales, including the mining, agriculture, health and food industries, there has been a reduction in nitrous oxide emissions of over 95% compared with 2019 levels.

To facilitate the project, the NSW Government’s Net Zero Industry and Innovation Program co-invested A$13.06 million ($8.33 million), together with Orica’s A$25 million financed by the Federal Government’s Clean Energy Finance Corporation. The Clean Energy Regulator also approved the project as eligible to generate Australian Carbon Credit Units.

Orica Group Executive and President Australia Pacific, Germán Morales, said: “This is another proud and critical milestone in Orica’s decarbonisation journey and ambition to achieve net zero emissions by latest 2050.

“We are accelerating action to reduce greenhouse gas emissions today, ensuring a sustainable future for our manufacturing facilities and supporting customers in achieving their sustainability goals. We are already seeing the benefit of this technology at our Kooragang Island facility, with an annual estimated reduction of 500,000 t of carbon dioxide equivalent. Now, as we continue our decarbonisation efforts, we will focus on installing the same proven technology at our Yarwun facility.”

Having invested to deliver significant reductions in net operational Scope 1 and 2 greenhouse gas emissions across some of its major manufacturing facilities, Orica says it is expecting a total reduction of at least 19% at the end of its 2023 financial year, from 2019 baseline levels. This supports Orica’s accelerated climate target to reduce net operational Scope 1 and 2 emissions by at least 45% by 2030, from 2019 levels.

Orica’s Kooragang Island facility is presently one of NSW’s largest industrial users of gas – using approximately 10-15% of total NSW gas per year. The next step for Orica in reducing these site-based emissions will be the use of renewable hydrogen as a feedstock, rather than natural gas used today. Orica hopes to further reduce its Scope 1 emissions while producing low-carbon ammonia for possible export and freeing up domestic gas supply for Australian households.

Partnering with Origin Energy on the Hunter Valley Hydrogen Hub, Orica is aiming to deliver a commercial-scale renewable hydrogen supply chain in the Newcastle industrial and port zone. The Hydrogen Hub will be located next to Orica’s Kooragang Island manufacturing site in Newcastle, in recognition of the competitive advantages of a strategic location on the Port of Newcastle and an established end market. It is also the only ammonia plant operating on Australia’s east coast with direct access to a deep-water port and the Port of Newcastle’s Clean Energy Precinct.

Penny Sharpe MLC, NSW Minister for Climate Change, Minister for Energy, Minister for the Environment, and Minister for Heritage, today announced funding from the NSW Government’s Hydrogen Hubs Initiative of A$45 million to progress the proposed Hunter Valley Hydrogen Hub on Kooragang Island. The NSW Government funding announcement follows a A$70 million contribution from the Federal Government announced in mid-July.

Orica and Origin recently signed a joint development agreement to progress plans and co-fund the proposed Hub through front-end engineering design, and continue to engage with the local community through the recent public EIS exhibition process.

Morales said: “We are deeply committed to continuing support for our customers by future-proofing our regional manufacturing, jobs and economies. As we progress plans to develop the Hunter Valley Hydrogen Hub, by leveraging our unique location, existing operations, experience and end markets, we will not only address some of our most material greenhouse gas emissions but also create future markets for Orica while supporting our customers as the world transitions.”

Rio Tinto, Sumitomo Corp to cut alumina refinery emissions with Gladstone hydrogen plant

Rio Tinto and Sumitomo Corporation are to build a first-of-a-kind hydrogen plant in Gladstone, Australia, as part of a A$111.1 million ($74.6 million) program aimed at lowering carbon emissions from the alumina refining process.

The Yarwun Hydrogen Calcination Pilot Demonstration Program received the green light after a A$32.1 million co-funding boost from the federal government’s Australian Renewable Energy Agency (ARENA).

The program is aimed at demonstrating the viability of using hydrogen in the calcination process, where hydrated alumina is heated to temperatures of up to 1,000°C.

It involves construction of a hydrogen plant at the refinery and the retrofit of refinery processing equipment. If successful, the program could pave the way for adoption of the technology at scale globally, Rio says.

Rio Tinto Aluminium Pacific Operations Managing Director, Armando Torres, said: “This pilot plant is an important step in testing whether hydrogen can replace natural gas in Queensland alumina refineries. At Rio Tinto we have put the energy transition at the heart of our business strategy, and this is one of the ways we’re working towards decarbonising our operations.

“We are proud to be developing this new technology here in Gladstone, in partnership with Sumitomo Corporation, and with support from ARENA.”

The project will consist of construction of a 2.5 MW on-site electrolyser to supply hydrogen to the Yarwun refinery and a retrofit of one of Yarwun’s four calciners so it can operate at times with a hydrogen burner.

The trial is expected to produce the equivalent of about 6,000 t/y of alumina while reducing Yarwun’s carbon dioxide emissions by about 3,000 t/y.

Converting the entire plant to green hydrogen could reduce emissions by 500,000 t/y, Rio estimates, the equivalent of taking about 109,000 internal combustion engine cars off the road.

Construction will start in 2024. The hydrogen plant and calciner are expected to be in operation by 2025.

Sumitomo Corporation will own and operate the electrolyser at Yarwun site and supply the hydrogen to Rio Tinto directly. The electrolyser will have a production capacity of more than 250 t/y of hydrogen.

Sumitomo Corporation Energy Innovation Initiative Director, Seiji Kitajima, said: “We are excited to be delivering this hydrogen project together with Rio Tinto as our long-term partner with the support of ARENA.

“Demonstrating real-world applications of hydrogen in industrial settings with motivated partners is essential to reducing carbon emissions and working toward our company’s vision of achieving carbon neutrality by 2050. Through this demonstration, Sumitomo Corporation aims to venture into the commercialisation project to contribute to Rio Tinto’s decarbonisation.

“Sumitomo Corporation is proud to be working on yet another hydrogen project in Australia and contributing to Australia’s own emission reductions goals.”

The pilot plant follows the success of a A$1.2 million feasibility study co-funded by Rio Tinto and ARENA that was announced in 2021.

Rio Tinto says it is committed to achieving net-zero emissions by 2050 and has targets to reduce Scope 1 & 2 emissions by 50% by 2030 from 2018 levels.

Orica’s Chemicals business eyes new complementary opportunities

Orica’s Investor Day, taking place last week, highlighted potential growth areas in one of the company’s less-publicised ‘verticals’, its Chemicals business.

Mining, Quarry & Construction and Digital solutions often steal the headlines in quarterly updates, but Adam Hall, Group Executive & President of Asia & Chemicals, showed there is plenty going on within the company’s fourth vertical.

This business, which covers the fields of ore processing, chemical stabilisation and recovery & treatment, strengthens Orica’s presence across the mining value chain, having a strong alignment with its global footprint and understanding of customer needs, the company says. It also acts as a complementary component of Orica’s “new solutions offerings”.

Orica’s current exposure is to leaching agents and emulsifiers, with cyanide making up its biggest product today.

As one of the largest producers of sodium cyanide for mining, Orica delivers the leaching agent in briquette form in circa-1 tonne boxes that are easily containerised, or within an Orica-designed Sparge isotainer system, or in liquid form via purpose-built iso tanks suitable for safe road or rail transport around the world.

It relies on the Yarwun, Gladstone Cyanide Manufacturing Facility in Queensland for this supply, which has an annual capacity of 95,000 t/y and is compliant with ISO9002 and the International Cyanide Management Code. This facility is complemented by the company’s sodium cyanide transfer stations in Peru, Ghana and Malaysia.

Hall was positive about potential growth opportunities in the cyanide space, explaining demand for cyanide was expected to outpace the predicted growth in gold ore treated to 2026 as the complexities involved with treating orebodies continued to increase.

He said the Yarwun facility had great brownfield growth opportunities around the site, with the company evaluating potential expansions in the region of “high single digit” or “low double digit” percentages.

Hall was equally positive about cyanide retaining its presence in the gold leaching process, saying that, while substitution questions continued to come up, the realities associated with such a transition meant it was infrequently feasible.

“There is one major mine that has switched away from using cyanide into a different reagent,” he said. “That cost them north of $100 million, and our understanding is they would not necessarily do it again. Also, that specific mine has a certain lithography that lent itself to using that reagent.”

Hall said Orica’s emulsifiers – which allow it to differentiate its explosives products through maintaining the stability of the mixture – represented “a small but mighty part” of the company’s product suite. He saw potential growth opportunities for emulsifiers, which he said contained the “secret sauce for emulsification”.

Outside of these two Orica mainstays, Hall highlighted the potential for Orica to play in both flotation and solvent extraction markets as part of growth opportunities that added up to A$23 billion ($16 billion).

In flotation, collectors, frothers and flocculants are integral to optimising the process. The same can be said for solvent extractants in the SX space.

“We see all of these as potentially interesting for Orica,” Hall said. “These are all big fields…but each of them has something we could potentially partner or bring to our clients, and something we will be looking to do over the next five years or so.”

Partnerships could potentially see Orica team up with big chemical players that have a by-product or comparatively small value stream coming out of an integrated facility where Orica could bring its “deep understanding of what the miners need and how we can deliver against that using the products that are produced”, he explained.

This could see Orica act as an agent, an offtaker, or purchaser of the by-product production unit.

As with all other Orica verticals, the Chemicals business will be looking at any potential bolt-on to the emulsifier and cyanide offering as a way to influence more of the value chain, ensuring changes made up- or down-stream provide value throughout the full flowsheet.

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.

Alpha HPA signs reagent and offtake deal with Orica

The Board of Alpha HPA Limited has executed binding, definitive agreements with Orica Australia in respect of Alpha HPA’s First Project in Gladstone, Queensland.

The agreement relates to the supply of process reagents and the offtake of process by-product to/from Alpha HPA’s First Project and Orica’s Yarwun manufacturing facility within the Gladstone State Development Area in north Queensland.

The nature of the HPA First Project process is such that the use of reagents and the manufacture of by-product is highly complementary to the existing processes in operation at the Orica Yarwun facility, Alpha HPA says. The agreements secure the commitment from both Orica and Alpha to leverage the process synergies to unlock the value from both companies’ projects, it added.

The agreement comprises a Project Implementation Agreement, which describes the capital investment obligations of the parties and the scope for project commissioning and reagent and by-product validation trials. This includes the construction of the full-scale HPA First Project by Alpha HPA and, for Orica, the construction of the piping, tankage and process controls required to deliver reagents to, and receive by-product from the HPA First project.

The agreement confirms a 10-year initial term with an optional extension of 10 years by mutual agreement.

Alpha HPA’s First Project represents the commercialisation of the production of circa-10,000 t/y equivalent of high-purity alumina and related products using the company’s proprietary licensed solvent extraction and HPA refining technology. The technology provides for the extraction and purification of aluminium from an industrial feedstock to produce 4N (>99.99% purity) alumina for the intended use within the lithium-ion battery and LED lighting industry.

Rio Tinto’s debut Amrun bauxite shipment sets sail

Rio Tinto has completed the first shipment of bauxite from its Amrun mine in Queensland, Australia, six weeks ahead of schedule.

At a ceremony on the Western Cape York Peninsula in the far north of Queensland, more than 80,000 t of bauxite was loaded on to the RTM Weipa bound for Rio’s Yarwun alumina refinery in Gladstone.

The US$1.9 billion (A$2.6 billion) investment in Amrun is aimed at replacing production from the depleting East Weipa mine and increasing annual bauxite exports by around 10 Mt. Amrun is expected to reach a full production rate of 22.8 Mt/y during 2019.

Rio Tinto Aluminium chief executive Alf Barrios said: “Bringing Amrun online further strengthens our position as a leading supplier in the seaborne market. We have the largest bauxite resources in the industry and are geographically well positioned to supply China’s significant future import needs, as well as supporting our refinery and smelting operations in Australia and New Zealand.”

The mining major was able to bring Amrun in ahead of schedule thanks, in part, to an innovation in design and fabrication of key infrastructure purpose-built for construction at Amrun’s remote location, according to Rio Tinto Growth & Innovation Group Executive Stephen McIntosh.

This included design and fabrication of the wharf on the Western Cape York Peninsula, which was constructed over water in essentially 13 pieces.

During construction, the Amrun development set a benchmark in supporting local and regional suppliers with US$1.6 billion invested with Australian companies, including $181 million with local Cape York companies, Rio said.
