Boston Metal Raises $250 Million for Green Steel Production Using Molten Oxide Electrolysis

Boston Metal, a startup spun out of MIT research, has secured $250 million in funding to develop an innovative green steel-making process that utilizes molten oxide electrolysis. The company aims to significantly reduce the steel industry's carbon emissions, which currently account for 7-9% of global CO2 emissions.

The urgency for sustainable steel production is evident, as steel demand is projected to surge to 2.5 billion tonnes by 2050 due to the energy transition. Boston Metal's patented Molten Oxide Electrolysis (MOE) platform offers a cleaner alternative to traditional coal-based steel production methods, setting the stage for large-scale sustainable steel manufacturing.

The startup is working on an alternative to the conventional carbon-based iron oxide reduction method, a major contributor to CO2 emissions. The new process, called Direct Reduced Iron (DRI), employs a reducing gas such as hydrogen or carbon monoxide to directly reduce iron ore, resulting in a substantial decrease in carbon dioxide emissions. Automation and X-ray diffraction (XRD) technology can further enhance the efficiency and monitoring of the DRI process, enabling faster analysis and real-time adjustments to optimize parameters.

Why this matters: The steel industry's transition to sustainable production methods is crucial in the fight against climate change. Boston Metal's innovative technology has the potential to transform the industry and significantly reduce its carbon footprint, contributing to global efforts to mitigate the impacts of climate change.

The transition to electric vehicles presents a critical opportunity to drive the decarbonization of the steel and aluminum industries, as automakers are major buyers of these materials. Automakers can catalyze these transitions by setting ambitious commitments and signing agreements directly with producers for the supply of fossil-free steel and aluminum. However, it is essential to ensure that these agreements are substantive, disclose adequate details, and are ambitious enough to lead industries towards full decarbonization, rather than relying on partial changes that keep production processes fundamentally reliant on fossil fuels.

The U.S. Department of Energy (DOE) has announced $28 million in funding for 13 projects across 9 states to advance zero-process emission ironmaking and ultra-low life cycle emissions steelmaking. The funded technologies aim to meet both emissions and cost parity goals. "The projects seek to transform the entire steel supply chain from ore to final steel production, with the goal of reducing the industry's significant carbon emissions, which account for 7-9% of global CO2 emissions," the DOE stated.
