About project

Horizon Europe project HAlMan

The project HAlMan stands for Sustainable Hydrogen and Aluminothermic Reduction Process for Manganese, its Alloys and Critical Raw Material Production. The project is co-funded by the European Union under the grant agreement ID 101091936. The project has started on the first of January, 2023.


The aim of the project

The aim is to demonstrate the HAlMan process for Mn and Mn alloys production in pilot scale. These metals will be further used to produce several tons of Mn-containing commercial steels and aluminum alloys. In addition, the project aims to produce manganese dioxide for battery applications and demonstrate the production of metallurgical grade alumina and commercial cements from process byproducts. The mapping and extraction of Critical Raw Materials, including Rare Earth Elements (REEs), is the other aim of HAlMan.

HAlMan will
develop & test

HAlMan consortium will develop and test a unique process that will ensure more effective and sustainable production of Mn and Mn alloys with various potential applications. For example:

The main objectives & the implementation process of the project

Why this project is important?

About 1.4 million tons of manganese ferroalloys were produced in Europe in 2020, relying on about 1.3 million tons of manganese ore that were imported and 0.6 million tons of manganese ores produced, leading to more than 1.8 million tons of CO2 emissions, which is about 2.5% of the EU metallurgical industries total CO2 emissions.

In 2020, Europe imported about 111.000 tons of are electrolytic manganese and 38.000 tons of electrolytic manganese dioxide. The latter is critical in the years to come for the battery industry, which expects significant growth. In addition, for the next few decades, the EU metallurgy industry will have to deal with a requirement to remain sustainable while maintaining economic competitiveness and maintaining the green course.

“One of the most important outcomes of this project is the strategic foundation for increasing the production of valuable metals via sustainable and resource efficient processes in a European framework. The technology developed in HAlMan will benefit mining, ferroalloys, iron foundry, steel, alumina.”

Student involvement in
the project

NTNU is the largest university in Norway and has a prominent profile in science and technology, with about 44000 students. “Knowledge for a better world” is the NTNU vision, and about 400 PhDs graduated from the university, completing their study in various programs. The PhD candidates do research at the NTNU to build knowledge, pave the way for scientific and technological developments, and benefit society. The results of PhD student research will be used to further implement the process on a pilot scale with the consortium partners.

HAlMan team at the first

January, 2023, Trondheim, Norway

The first consortium meeting was a great opportunity for all the consortium partners meet and discuss in detail the implementation of the project. 2-day meeting hosted more than 43 participants in hybrid mode.
