International forum to forge new pathways in zero carbon high temperature mineral processing

HiTeMP-2 Forum

After the success of the inaugural High Temperature Minerals Processing Forum (HiTeMP) held in 2018, delegates from around the world will once again converge on Adelaide for HiTeMP-2. Building on the outcomes of HiTeMP-1, the internationally leading forum will continue to drive a multi-stakeholder perspective of pathways to transition heavy industry toward net-zero CO2 emissions.

High temperature processes are commonly used around the world to produce goods vital to the global economy such as steel, cement, copper and aluminium. They are energy intensive, have a much greater requirement for heat than electricity and operate with large volumes and low profit margins from capital intensive plant in trade exposed markets.

These features, together with the lack of commercially available renewable energy technologies for high temperature process heat, mean that the sector has been identified “difficult to abate” with regard to CO2 emissions. However, these unique challenges are also resulting in new opportunities.

New opportunities are emerging for countries with a coincidence of renewable energy and mineral resources, so that leading mineral processing and refining companies across the world have already started to respond to emerging markets for low carbon products.

These markets are driving industry and governments to invest in the development of new technologies with strong potential to lower CO2 intensity in response. Rapid advances are therefore being made to meet this need at a competitive price.

HiTeMP-2 will bring together some of the world’s best minds and speakers from a range of processes, nationalities and backgrounds to discuss this challenge, spanning industrial end users, technology providers, researchers, government agencies and non-government organisations. The forum will examine how key technologies such as solar thermal, green hydrogen, green electricity and refuse derived fuels can be further developed and commercially implemented at industrial scales.

Mr Toru Ono, Technical Director from Nippon Steel, and Professor Ellen Stechel from Arizona State University are among the many speakers, who will explore the global drivers and technologies that are leading to the ongoing decarbonisation of high temperature processing in heavy industry.

Professor Gus Nathan, Director of the Centre for Energy Technology, at the University of Adelaide and co-founder of the forum, says that HiTeMP-2 presents a unique opportunity for stakeholders to chart the pathway towards net-zero-CO2 emissions for the sector.

“The question of how to transform the heavy industry sector to operate carbon-neutral with emerging technology in an economically sustainable way is attracting growing interest, both nationally and internationally” he says.

“There is no getting around the fact that the high temperature mineral processing industries are vital to the global economy or that demand for their products is expected to grow. However, industry needs support to transform because it is responsible for one third of global CO2 emissions – of which half is for high temperature processes (typically more than 800oC).

“Forums such as HiTeMP are crucial in setting the agenda and bringing leaders from around the world together to create a better future together.”

The event is an open forum to examine the drivers and potential pathways to transform the sector. It will address:

  • Next steps for the iron/steel, alumina/cement and new energy metals industries
  • Emerging opportunities to lower the carbon intensity of these processes
  • Identification of exemplars in lowering CO2 intensity from minerals processing in nations with a strong coincidence of mineral and renewable energy resources
  • key drivers, technologies and trends
  • the next steps for the sector, including key enablers, projects and demonstrations needed to de-risk future investments.

Professor Nathan added, “There is no doubt that the impetus to change the sector is gaining traction world-wide. However, these changes are happening relatively quickly in many places around the world, so that knowledge sharing, new partnerships and coordination is needed to accelerate the technology development, upscaling and demonstration toward commercial implementation.

“HiTeMP-2 will help to foster the linkages and understanding that will ensure the investment in all of our future not only continues, but grows significantly.”

HiTeMP-2 is an initiative of The University of Adelaide’s Centre for Energy Technology (CET), which delivers innovative technologies for sustainable, secure and affordable energy. CET collaborates with industry and other global research leaders to reduce emissions from the heavy industrial sector for the new, low-carbon economy.  The centre works with technologies that are implementable in real industrial processes, both those that have been initiated elsewhere and those that CET has invented.
