Eying sustainability gains for its supply chain, BMW backs Boston Metal’s CO2-free iron production tech

Looking to decarbonize the metal industry, Bill Gates-backed Boston Metal raises $50 million

Through a commitment from BMW iVentures, the automaker’s investment arm, Boston Metal will have an in to a company with massive demands for more sustainably manufactured metal. For instance, BMW Group press plants in Europe process more than half a million tonnes of steel per year, the company said.

“We systematically identify the raw materials and components in our supplier network with the highest CO₂ emissions from production,” said Dr Andreas Wendt, member of the Board of Management of BMW AG responsible for Purchasing and Supplier Network, in a statement. “Steel is one of them, but it is vital to car production. For this reason, we have set ourselves the goal of continuously reducing CO₂ emissions in the steel supply chain. By 2030, CO₂ emissions should be about two million tonnes lower than today’s figure.”

Conventional steel production requires blast furnaces that generate carbon dioxide emissions, but using Boston Metal’s process, an electrolysis cell produces the pig iron that gets processed into steel, the company said.

The addition of BMW to its investor group, which already includes Bill Gates’ Breakthrough Energy Ventures and other strategic and financial investors, caps the fundraising process with another corporate partner wielding incredible industry influence.

“Our investors span across the steel value chain, from the upstream mining and iron ore companies to the downstream end customer, and validate Boston Metal’s innovative process to produce high-quality steel, cost-competitively, and at scale,” said chief executive officer and founder, Tadeu Carneiro.
