Boston Metal is at the forefront with an innovative approach to steel production – one that uses electricity. Their aim is to substantially reduce the carbon emissions associated with conventional steel production. With an industry currently responsible for 11% of global CO2 emissions, Boston Metal is on the front lines of an underreported transformation. Their work becomes even more imperative as the world faces the reality of climate change and urgently needs to lower greenhouse gas emissions.
The company’s demonstration plant in Colorado produces 500 tonnes of iron annually through an advanced electric process that extracts iron from ore, marking a departure from conventional methods. Co-founder and chief executive Sandeep Nijhawan elaborated on the process, stating, “These plates are extracted automatically out of the solution and the iron is harvested.” This pioneering method is one of the few ways to proactively remove carbon emissions. It makes renewable electricity the preferred energy source for any steel produced.
The U.S. steel industry is already an environmental outlier. This success is due in large part to electric arc furnaces, which are commonly used by steelmakers. Transitioning from carbon emissions-intensive blast furnaces to electric arc furnaces can reduce carbon emissions more than 90 percent. The move reduces emissions from 2.32 tonnes of CO2 to only 0.67 tonnes per tonne of steel produced. This transition is a big move in the direction of a more environmentally sustainable steel-making process.
Simon Nicholas, lead steel analyst at Institute for Energy Economics and Financial Analysis. He stresses the importance of renewable energy in enabling greener steel production. He noted that a plentiful supply of renewable energy is essential, stating, “We’re running short of time for addressing carbon emissions.” He touted green hydrogen’s ability to revolutionize iron-making. Such green hydrogen, produced from electrolysis powered with 100% renewable energy, would have a potentially key role at Boston Metal and similar places.
Yet, challenges persist for the burgeoning green steel market. Even Cleveland-Cliffs, one of the largest U.S. steel producers, just reduced the scope of its proposed $500 million hydrogen-powered steel plant in Ohio. The company alluded to challenges in the industry as contributing to this decision. Nicholas commented on the current state of green steel projects, saying, “We’re seeing projects cancelled, proponents pulling out of projects all over the place.”
The U.S. government’s changing stance on renewable electricity has impacted Boston Metal’s operations. President Donald Trump’s tariffs on steel imports would significantly increase costs for U.S. customers—including Boston Metal! This challenging economic landscape only serves to heighten the company’s imperative to penetrate the competitive market quickly and efficiently.
Adam Rauwerdink, a steelmaking consultant, gave a poignant example of what the future of steel production looks like. “People are dropping off their kids. That kind of shows you an extreme example of what the future of steel looks like,” he remarked. This complex feeling marks the social change that always comes under the influence of technological progress in steelmaking.
Boston Metal is hard at work creating cleaner production methods. It is at the forefront of the fight in a booming industry ripe for disruption. The company’s approach is not so different from the current processes used to manufacture copper and zinc sheets. It further lays the groundwork for advancing more sustainable, equitable practices.
