BMW Group Invests In Innovative Method For CO2-Free Steel Production

The BMW Group announced that it is investing in an innovative method for CO2-free steel production developed by American startup Boston Metal, through its venture capital fund, BMW i Ventures. Over the coming years, Boston Metal plans to expand the new method for steel production on an industrial scale. The investment is part of the BMW Group's far-reaching sustainability activities aimed at significantly reducing CO2 emissions across the supplier network.

To safeguard reserves of raw materials, the BMW Group has set itself the goal of further increasing its percentage of recycled raw materials

With its versatile properties, steel is one of the most important materials in car production and will be no less important for future vehicle generations. Even with the dynamic ramp-up of electromobility, steel will remain an important building material for car bodies and many components. BMW Group press plants in Europe process more than half a million tonnes of steel per year.

The blast furnaces used in conventional steel production generate carbon dioxide. The startup Boston Metal uses electricity for its new technology, which, by means of an electrolysis cell, produces molten iron that is later processed into steel. If electricity from renewable energies is used for this process, then steel production is carbon-free. The young company will build demonstration facilities for this process over the next few years and further develop it for use on an industrial scale.

The BMW Group established close contact with Boston Metal already last year in the context of its own research activities and through the BMW Startup Garage. The company is now investing in the startup as part of its i Ventures activities.

To safeguard reserves of raw materials, the BMW Group has set itself the goal of further increasing its percentage of recycled raw materials, so-called secondary material, by 2030 and using raw materials multiple times in a circular economy.

All steel waste produced at the press plants – for example, when doors are punched out – is either reused through a direct material cycle or sent back to the steel producer via steel traders and processed into new steel. The use of secondary material reduces CO2 emissions substantially compared to primary material, conserves natural resources and also reduces the amount of energy needed for production.
