Electra has raised $85 million to supply Low-Temperature Iron (LTI) from industrial and low-grade ores utilizing zero-carbon intermittent electrical energy. Electra’s course of emits zero carbon dioxide emissions and carries zero inexperienced premium, which means it should price the identical or lower than current manufacturing strategies powered by fossil fuels.
Electra, based by entrepreneurs with many years of expertise growing complicated electrochemical techniques, has created a novel course of to refine iron ore into pure iron electrochemically at 60 levels Celsius (140 levels Fahrenheit) utilizing renewable electrical energy after which convert the iron to metal utilizing the present infrastructure of electricity-powered arc furnaces.
By comparability, 69% of metal at this time is made at roughly 1,600 levels Celsius (2,912 levels Fahrenheit) utilizing coal, emitting about two tons of carbon dioxide for each ton of metal produced.
Electra developed a way of dissolving iron ore and eradicating impurities whereas retaining iron in aqueous resolution, thereby unlocking the chance to make use of low-grade ores in its course of.
Electra’s Oxygen-Decoupled Electrolysis (ODE) course of overcomes two interconnected challenges for the metal business:
-
Decarbonizing Steelmaking: The metal business produces 1.9 billion metric tons of crude metal and causes 3.7 gigatons of direct and oblique carbon dioxide emissions yearly, or 10% of the worldwide whole. If the metal business have been a rustic, its carbon emissions would rank third on the earth behind China and america. Conversion of iron ore into iron accounts for 90% of steelmaking emissions which may be eradicated utilizing Electra’s course of.
-
The “Iron Ore Problem”: Industrial iron ores with iron content material of 62% or increased are projected to be briefly provide by the early 2030s. Hydrogen or pure gas-based steelmaking requires ores with the best iron content material at 67% or above, making the associated fee and ore provide problem much more acute for these processes. Electra’s course of intakes lower-grade ores with iron content material as little as 35% with out the extra price of grinding, beneficiation, and pelletization, enabling zero inexperienced premium and a extra numerous iron ore provide chain.
Electra’s iron is the fulcrum to decarbonize steelmaking and to de-risk the iron ore problem. Our crew, beginning with a clear sheet, developed an electrochemical course of to refine iron ore to excessive purity iron by radically decreasing the method temperature from 1,600 to 60 levels Celsius, changing coal vitality with intermittent renewable vitality, and displacing industrial ores with lower-grade ores that aren’t getting used or are at present handled as waste at this time. We even have a historic alternative to decentralize the worldwide iron and metal provide chain and re-shore manufacturing and mining jobs.

Electra says that it leverages confirmed electrochemical and hydrometallurgical strategies to achieve industrial scale with low technical and scaling dangers. Electra will full the build-out of a green-iron refining pilot plant in 2023 at its headquarters in Boulder, CO, and plans to have a commercial-scale demonstration plant certified by the second half of this decade.
The 50-person firm lately opened a brand new workplace in Boston, MA to assist develop its roster of engineers, scientists, {and professional} assist employees.
The corporate is backed by Invoice Gates-founded Breakthrough Power Ventures, Amazon, BHP Ventures, Temasek, S2G Ventures, Capricorn Funding Group, Lowercarbon Capital, Valor Fairness Companions, Baruch Future Ventures and others.
Electra plans to forge extra partnerships throughout the complete metal worth chain. Iron ore firms, metal firms, and any firm that depends on metal are invited to collaborate with Electra to speed up the transition to inexperienced metal.
