OceanaGold to set GHG emission targets on its way to ‘net zero’ goal

OceanaGold has become the latest miner to make a climate change pledge, releasing a position statement on the subject that includes an emissions reduction goal to achieve net zero emissions from its operations by 2050.

Included within this position statement is a plan to decarbonise its electrical energy supply and mobile equipment fuel.

The goal is core to OceanaGold’s environmental management strategy to mitigate the risks associated with climate change, establish measures and targets to improve the efficiency of its energy use and to minimise its greenhouse gas (GHG) emission intensity, the company said.

Michael Holmes, President and CEO of OceanaGold said: “OceanaGold has been strongly committed to responsible mining for 30 years, and, with current emissions lower than global industry average, we are already on the journey to reduce our carbon footprint.

“OceanaGold fully supports the Paris Agreement’s goal of limiting the increase in global average temperature to well below 2°C above pre-industrial levels. In line with this objective, we are setting a goal to achieve net zero GHG emissions from our operations by 2050, and we will establish milestone intensity targets (GHG emissions per ounce of gold produced) by 2022 to support this goal.”

Delivery of net zero carbon emissions production will rely on step changes from new and emerging technologies to decarbonise OceanaGold’s electricity supplies and mobile equipment use and incrementally improving energy use, efficiency and reducing energy consumption, the company said.

Since 2018, OceanaGold has been implementing a company-wide program of automation, digital and process transformation called ADaPT. This is helping define the company’s journey to operate the mines of the future, it said.

“Digital transformation presents an industry-wide opportunity to enhance performance and reduce impact,” Holmes said. “Successful implementation of the rapid advances in technology, innovation, automation, digitisation and electrification are central to achieving OceanaGold’s commitment to reduce our environmental impact.”

OceanaGold has established a roadmap of strategic actions to help reduce its carbon footprint and improve energy management, including:

  • Setting the goal to achieve net zero GHG emissions by 2050;
  • Establishing milestone interim emission targets by the end of 2021, linked to employment performance incentives;
  • Establishing a climate change Technical Coordinating Committee to identify opportunities to reduce GHG emission intensity and identify risks, opportunities, priorities and costs across OceanaGold; and
  • Undertaking climate change management and reporting to meet the requirements of the Task Force on Climate-related Financial Disclosures (TCFD).

Targets will be achieved through the implementation of four key strategic areas: improved energy efficiency and energy reduction; decarbonisation of electrical energy supply; decarbonisation of mobile equipment fuel; and carbon sequestration, the company said

ABB and Hydrogen Optimized to study large-scale green hydrogen production systems

ABB and Hydrogen Optimized have signed a Memorandum of Understanding (MoU) to explore the development of large-scale green hydrogen production systems connected to the electrical grid to offer a clean, sustainable and affordable energy source for industries such as mining.

Hydrogen Optimized has ambitions to use its high current water electrolysis technology at scale to produce green hydrogen for emerging clean applications across industries, including chemical, utility and transportation. ABB’s hydrogen research team, meanwhile, will explore electrical power supply optimisation through projects involving ABB high power rectifier (HPR) systems.

Together, the companies plan to prove that Hydrogen Optimized’s RuggedCell™ water electrolysis technology can be used to develop an integrated product solution based on a 100 MW single module plant design concept, they said.

Within ABB’s HPR range, rectifier systems provide DC current in the range of 5,000 A to 550,000 A, as single or multiple units and, as such, can provide nearly unlimited current and voltage combinations and meet most plant specific requirements, the company says.

“ABB is a world leader in the control and electrification solutions designed for large-scale electrochemical processes,” Andrew TB Stuart, President and CEO of Hydrogen Optimized (pictured), said. “Such technology is an excellent fit with our patent pending RuggedCell. Together these technologies create a continuous reduction in the installed capital cost as the scale of the green hydrogen project increases.

“Our joint work will lay the foundations for single-plant sizes up to the hundreds of MWs input power range. Demonstrating the scalability of these two key components of a water electrolysis installation is vital to economic green hydrogen and we are excited about the potential benefits for customers.”

The MoU signed by the companies formalises the agreement to explore the implementation of a demonstration system as well as the preparation of a 100 MW plant design and commercialisation strategies, the two said.

Charl Marais, Global Product Manager, Process Industries, ABB, said: “This project plays to our strengths of building large, highly efficient, customised HPR systems, pushing the boundaries of what is possible from one rectifier unit. Based on our many years of experience in providing control and electrical system solutions for electrochemical industries, we understand that HPR systems have the characteristics required for successful large-scale project deployment.

“This collaboration advances the commercial availability and feasibility of large-scale green hydrogen systems. We have been exploring this type of project for more than two years and the synergies with Hydrogen Optimized have been very apparent. We have a clear vision, and the results could be significant.”

Applications using green hydrogen include zero-emission transportation fuel supply, ammonia and other chemical production with non-fossil sources of hydrogen, and green metal production with hydrogen instead of a coking-type process, the companies say.

2BL to take ‘reuse + repurpose – recycle’ message to battery-electric vehicle market

2nd Battery Life Inc has appointed a new President and CEO that, it hopes, will position the company ahead of the curve on the downstream reuse of batteries for battery-electric vehicles (BEVs) in mining.

Vernon Cameron has been appointed to the top job, joining Chairman & Chief Technology Officer – and battery-electric vehicle specialist – Mike Mayhew on the executive team.

Cameron brings a wealth of experience in private equity, private and public companies with over 30 years of senior level experience on a global basis, according to the company. His hands-on experience in manufacturing environments, as well as global sourcing connections, will maximise profitability and drive enterprise value, it said.

Mayhew, who with Stacktronic is currently working on repurposing and electrifying a personnel carrier for use in the underground mining sector under the guise of his Mayhew Performance company, said he was “extremely excited” to launch 2nd Battery Life Inc to the market.

“The need for 2BL is critical for the future of battery electric as we implement more BEVs within the mining operations, as part of the overall equipment life cycle towards zero emissions.

“2BL will be the cornerstone of ‘reuse + repurpose – recycle” for mining clients on a global basis and we are going to create a Centre of Excellence to manage 2nd Battery Life.”

Cameron, who recently moved back to Sudbury, said: “The timing of entering this emerging market space positions 2BL to be ahead of the curve on downstream reuse of batteries for mining BEVs.”

DEUTZ to add hydrogen engines to zero-emission vehicles blueprint

DEUTZ AG and Munich-based start-up KEYOU have agreed to build on their existing partnership and jointly develop commercially viable carbon-neutral hydrogen engines for off-road and on-road applications.

The letter of intent, which will also include hydrogen engines for power generation, could see the two firms bring these engines to production readiness.

Underground mining equipment manufacturers such as GHH Fahrzeuge use DEUTZ engines in their LHDs.

DEUTZ said: “As a leading global manufacturer of innovative drive systems, DEUTZ is seeking to play a pioneering role in the development of high-quality, eco-friendly and efficient engines.

“Alongside the E-DEUTZ strategy, which launched last year and has been pursued with purpose ever since, the collaboration with KEYOU represents a further step forward in the advancement of alternative drive technologies and fuels.”

DEUTZ CEO, Dr Frank Hiller, said: “The use of alternative fuels such as hydrogen is growing in importance. We believe that this drive solution will be a valuable addition to our electrification strategy and play an integral role in the zero-emission vehicles of the future.”

By working on the development of a hydrogen combustion engine, DEUTZ is also offering an alternative to fuel-cell technology, it said. The company’s expertise in combustion engines is being combined with KEYOU-inside technology, which can convert conventional production engines to run on hydrogen. “The technology is extremely scalable, both for on-road and off-road applications, and it can be used in a range of hybrid configurations, including in combination with electric drives,” DEUTZ said.

KEYOU has developed a prototype for its KEYOU-inside technology that can turn a conventional diesel engine into a drive based on state-of-the-art hydrogen technology, according to DEUTZ.

DEUTZ provided support as a development partner, supplying the engine – one of its standard six-cylinder models – and sharing its engineering expertise. The resulting hydrogen combustion engine is extremely cost-efficient, which makes it an attractive alternative to electric drives, fuel-cell drives and other zero-emission systems, the company said.

KEYOU’s first 7.8-litre prototype DEUTZ engine was unveiled to the public in 2018 at the Bauma China trade fair and will also be showcased in April 2019 at the Bauma fair in Munich, Germany.

Specific pilot projects with vehicle manufacturers and end users are in the planning stage, with the appearance of the first prototype vehicles expected in the first half of 2020. The aim is to bring them to production readiness by 2021/22.

Alvaro Sousa, CTO of KEYOU, said: “Our new KEYOU-inside H2 combustion technology is not only cost-efficient, robust and powerful, but it is also perfect for use with DEUTZ engines thanks to its high degree of scalability.”
