What Does Electra's Clean Iron Tech Mean for Steel?

As the global expansion of data centres and electric vehicles continues, the demand is increasing rapidly. A Colorado-based startup, Electra, could have a cleaner alternative.

The company has partnered with Meta, Nucor and Toyota Tsusho America as it moves toward commercial deployment, revealing plans for a new demonstration plant in Jefferson County, Colorado, that could begin producing clean iron by mid-2026.

This facility is a critical step in the commercialisation of Electra’s “electrowinning” technology, an electrochemical process powered by renewable energy. It replaces fossil-fuelled blast furnaces with a low-temperature, low-emission alternative.

Scaling clean iron production

Steel is a fundamental component in sectors from construction and automotive to the structural frameworks inside hyperscale data centres.

The steel industry is responsible for approximately 9% of global greenhouse gas emissions, with the majority produced by coal-fired blast furnaces.

Electra's process utilises electricity instead of heat to separate iron from ore. By operating with renewables at a low temperature, this method eliminates the need for coal and high-temperature emissions.

“We started Electra to fundamentally reinvent the way the world makes iron [...] but we’ve always known we could not do it alone,” says Sandeep Nijhawan, Co-founder and CEO of Electra.

He believes that with partner support, Electra is “proving that pure iron can be made resourcefully and scaled quickly to meet global demand.”

The new demonstration project is supported by substantial private and public investment, and will have the capacity to produce up to 500 metric tonnes of iron per year.

Strategic partnerships and low-carbon materials

Electra’s partners include Nucor, the largest steel producer in the US and an early investor in the startup.

Nucor has committed to purchasing clean iron from the new facility.

Toyota Tsusho America will also acquire and distribute Electra’s iron to steelmakers that supply the automotive sector.

Germany’s Interfer Edelstahl Group will use the iron in its speciality steel operations.

“The advanced purchase commitments with Electra are a clear demonstration of Nucor’s belief in their clean iron technology,” says Al Behr, Executive Vice President of Raw Materials at Nucor.

He adds that the facility marks an “important milestone [...] in the journey to decarbonise the steel supply chain” and lays the groundwork for a new era of low-carbon materials.

Meta has taken a different route. Instead of purchasing iron directly, the company will acquire environmental attribute certificates from Electra.

These certificates will enable Meta to apply the emissions reductions from Electra’s clean iron production towards its own sustainability goals.

Through this offtake agreement, it is working towards demonstrating "a pathway for these innovative materials to scale," says John DeAngelis, Head of Clean Technology Innovation at Meta.

Decarbonising the digital infrastructure supply chain

While many decarbonisation efforts have centred on using green hydrogen, Electra’s electrowinning method avoids hydrogen entirely.

The process dissolves iron ore into a water-based solution and then uses electricity to deposit pure iron onto sheets.

This allows for the use of lower-grade ores that would otherwise be uneconomical. It also enables operations to adjust according to renewable energy availability.

The technology’s capacity to run on intermittent renewable power is especially relevant for data centre operators like Meta.

By aligning material production with clean energy supply, Electra’s process presents a potential model for decarbonising supply chains that support data centre construction.

Electra sources 100% renewable energy for its pilot operations and intends to do the same for the new Jefferson County facility.

Sandeep remains optimistic about Electra’s role in transforming the industry.

He insists that “the solutions are in hand and it’s a matter of scaling to drive those economics as fast as we can.”

For the rapidly growing data centre sector, where sustainability goals are now integral to investment and development, Electra’s partnership with Meta indicates a wider trend in the industry.
