Expert Q&A: Green steel production

In-Depth

Whilst steel is key to our low carbon future, its production is a leading cause of global CO2 emissions. The Engineer spoke to a panel of experts about progress in the development of so-called green steel production methods.

Used in everything from wind turbines to electric vehicles, steel is a key building block of the green revolution. But with its production responsible for around seven per cent of global CO2 emissions, existing processes clearly need to change. The Engineer spoke to a group of experts from across the steel sector to learn about the challenges of shifting production away from fossil fuels; the technologies that could help achieve this; and when - if ever  - we can expect high volume green steel production to become a reality.
