Boston Metal pioneers route to commercial production for eco-friendly steel method
Boston Metal, a Massachusetts-based company, is on the brink of earning its first revenue, as the demand for green steel continues to grow worldwide. Despite challenges on the supply side, particularly the scant and expensive supply of green hydrogen, the market for low-emissions steel is expected to increase significantly by 2030.
Kaitlyn Ramirez, senior associate with energy transition think tank RMI, has noted that the demand for green steel is there, and momentum is being seen, despite the challenges on the supply side. The technology used by Boston Metal is a promising alternative to traditional, emissions-intensive steel production.
Boston Metal's novel steelmaking process produces a small fraction of the emissions generated by traditional fossil fuel-fired blast furnaces. The company's unique approach involves molten oxide electrolysis, which differs from traditional methods. This process allows for the accumulation of molten iron, which is then tapped out of the chamber in a fiery, industrial process.
Significantly, the molten oxide electrolysis process produces no carbon dioxide emissions, making it a significant step towards sustainable steel production. The only greenhouse gas emissions associated with the process are those related to the electricity used to power the system.
Boston Metal has been financially supported by a range of investors, including Bill Gates, Breakthrough Energy Ventures, Eni Next, Equinor, ArcelorMittal, Saudi Aramco, M&G Investments, the World Bank's International Finance Corp., Microsoft's Climate Innovation Fund, and others, raising a total of over $400 million through various funding rounds since its founding.
Promoting green steel was a major element of former President Joe Biden's economic and environmental agenda. However, the Trump administration's desire to boost fossil fuels has already undermined these efforts, leaving the future of the sector in question.
It's worth noting that the steel industry is responsible for 7% to 9% of global emissions. In the United States, seven coal-fired steel production plants contribute to high pollution levels in the cities where they are located.
As the demand for low-emissions steel continues to rise, companies like Boston Metal are poised to play a crucial role in the transition towards a more sustainable future. The company's innovative technology and financial backing make it a strong contender in the race to develop a reliable and affordable source of green steel.
Despite the current limitations in the supply of green hydrogen, the potential benefits of hydrogen-fueled DRI (Direct Reduction of Iron) are clear. Kaitlyn Ramirez, senior associate with energy transition think tank RMI, has stated that hydrogen-fueled DRI is currently the most promising emerging alternative to traditional steel production.
However, it's important to address the current challenges in the supply of green hydrogen to make DRI a reliable source of low-emissions fuel. As these issues are addressed, the future of green steel looks increasingly promising.
