Elkem to pilot CO\2\-free silicon production with support from Enova

Elkem to pilot CO\2\-free silicon production with support from Enova

Elkem is researching a groundbreaking new concept for silicon production, which

aims to eliminate nearly all direct CO\2\ emissions. The concept involves

capturing and recycling the carbon in the process off gas and reusing it in the

production process.  Enova has granted Elkem 31 million Norwegian kroner for a

medium scale pilot, to be carried out in Kristiansand, Norway.

Silicon is a critical raw material for the green and digital transitions, as it

is used in electric vehicles, solar cells, batteries, computers, wind turbines

and much more. The production of silicon is however a source of greenhouse gas

emissions, as the process requires a source of carbon to reduce the quartz into

silicon. Elkem's silicon production is based on more than 80% emission-free

electricity and is one of the world's most sustainable silicon production

processes. The emissions from the carbon needed to produce silicon from quartz

is however hard to abate.

- Elkem has a climate strategy aimed at net zero emissions by 2050, and a switch

to more biocarbon and exploring carbon capture are among the company's measures.

With this groundbreaking research into carbon looping, possibly reusing captured

carbon in our own process, we are exploring a potential game changer in the

silicon production industry, said Elkem CEO Helge Aasen.

The new concept, named Sicalo (Silicon production with carbon looping), will

eliminate the need for any carbon used as a reduction material, if realized. In

today's silicon furnace, the process gases end up as CO\2\ emissions. In Sicalo,

the emitted carbon will be captured and reused in the silicon production process

as a reductant.

Elkem is about to complete the first phase of the research and development work

of Sicalo, where the various subprocesses are tested on laboratory and bench

scales together with SINTEF Industry and NORCE. The project has previously

received 16 MNOK in funding from the Research Council of Norway for this

research phase in 2022-2024.

- Enova is impressed by the extensive work Elkem has put into this pilot

project. This is future technology. It is therefore very natural that Enova is

involved and helps mitigate the risk through financial support. Enova knows that

it takes time to commercialize this technology. Now that Elkem is underway, we

can hope that the new solutions and processes can be industrialized early in the

2030s. We are following the results with excitement, says Nils Kristian Nakstad,

CEO of Enova

- We are pleased to receive public funding from Enova for this pilot project.

There is still significant research needed before we can see this as a viable

solution in full scale, but preliminary results are promising, and we are proud

to have world class researchers and pilot facilities for working on these

possible future technologies for the silicon industry, said Helge Aasen.

Elkem also completed the world's first carbon capture pilot in a silicon smelter

in 2023, with capture rates of up to 95 %.
