emissions from silicon production.
Elkem, SINTEF and NORCE are completing the first pilot phase of Elkem Sicalo® at
Elkem’s technology park in Kristiansand, Norway. The project entails capturing
the carbon emitted from the silicon furnace and reusing it as a reductant in the
silicon production process. The EU has now granted EUR 9.9 million in funding
for the Horizon Europe project MECALO, which builds on Elkem Sicalo®. MECALO
will develop the concept of carbon looping further for general metal production,
with demonstration of zero CO2 silicon and manganese alloys.
The manganese alloys producer Eramet, with its six smelters in Norway, France,
the United States and Gabon, is the other metallurgical company in the
consortium aiming to develop and use the technology from MECALO. If successful
and fully implemented in all European production of silicon and manganese,
MECALO could save 33 million tonnes of CO2 emissions per year in 2050.
“Our research into carbon looping has the potential to be a game changer for the
metal alloys industry to achieve net zero emissions. We are grateful to the EU
for supporting this groundbreaking project. Strong public-private partnerships
are essential for bridging resource gaps, spreading risk and leveraging
complementary competencies. Together, we are strengthening Europe’s resilience
in the critical raw materials value chains,” said Elkem CEO Helge Aasen.
Silicon is a raw material that is critical for the green and digital
transitions. Its application ranges from electric vehicles to solar cells,
batteries, smart phones and wind turbines. The production of silicon is a source
of greenhouse gas emissions, as the process requires carbon to reduce quartz
into silicon. Some metals, such as steel, can be produced with hydrogen as a
reductant. This is not possible for silicon, manganese and several other metals.
That’s why pioneering projects such as MECALO are needed, to develop innovative
production methods without CO2 emissions.
The MECALO project will research and develop a new production method that
involves capturing carbon oxides from process off-gases, converting them to
solid carbon using low-carbon hydrogen, and reusing the recovered carbon as a
reduction material to produce critical metals and materials. While this method
is showing promising results, it also presents challenges that need to be
resolved, such as increased energy use.
The overall budget for MECALO is EUR 9.9 million (NOK 116 million), with Elkem’s
budget and requested grant amounting to EUR 1.8 million (NOK 21 million).
Key highlights of the MECALO project:
· Innovative carbon capture and reuse:Capturing carbon oxides from off-gases
and converting them into solid carbon using hydrogen, which is then reused in
metal production
· Elimination of external carbon feedstock:The process aims to eliminate the
need for external carbon in carbothermic production
· Researching production of “turquoise hydrogen”: A project partner will
research methane pyrolysis, whereby methane is cracked into hydrogen and solid
carbon, using only a fifth of the energy required for green hydrogen production
Elkem has been working on Elkem Sicalo® with SINTEF as its research partner
since 2021, with support from The Research Council of Norway from 2022-2024. The
research partners are now initiating the second phase of the project with
extensive pilot testing of various stages of the production process, with
support from Enova.
“Significantly reducing greenhouse gas emissions while enabling the production
of green products is the recipe for competitiveness in a low-emission society.
Thanks to an ambitious research agenda, we are now in a position to deliver a
huge impact on European industry,” said Eli Aamot, Executive Vice President of
SINTEF Industry.
“Our ambition is to be the first producer to offer zero CO2 manganese alloys on
the way to decarbonizing the value chain of steel. Carbon looping is an
important lever for the long term, with a potential CO2-reduction of 90 per cent
compared with today’s level. The MECALO project provides a pragmatic and
industry-oriented solution through collaborative work from top European
companies, and I look forward to seeing the results,” said Bjørn Kolbjørnsen,
head of Eramet’s Mn Alloys business unit.
Carbothermic reduction in metal production
· Definition: Carbothermic reduction involves the reduction of metal oxides
using carbon as the reducing agent. This process is typically conducted at high
temperatures in furnaces.
· Applications: Commonly used in the production of metals such as silicon and
manganese, which are crucial for various industries, including electronics and
renewable energy.
· Process: The carbon reacts with the metal oxide to produce the metal and
carbon monoxide (CO) or carbon dioxide (CO\2).
· Environmental impact: Traditional carbothermic reduction processes produce
significant CO\2\ emissions. Innovative projects like MECALO aim to capture and
reuse the carbon, reducing the environmental footprint.
· MECALO Project: This project focuses on capturing carbon oxides from process
off-gases, converting them to solid carbon using low-carbon hydrogen, and
reusing the recovered carbon in metal production.
