Green steel

Shutterstock'Green steel' is hailed as the next big thing in Australian industry. Here's what the hype is all aboutJessica Allen, Tom Honeyands, University of NewcastleJune 2, 2021 4.01pm AESTSteel is a major building block of our modern world, used to make everything from cutlery to bridges and wind turbines. But the way it’s made – using coal – is making climate change worse.On average, almost two tonnes of carbon dioxide (CO₂) are emitted for every tonne of steel produced. This accounts for about 7% of global greenhouse gas emissions. Cleaning up steel production is clearly key to Earth’s low-carbon future.Fortunately, a new path is emerging. So-called “green steel”, made using hydrogen rather than coal, represents a huge opportunity for Australia. It would boost our exports, help offset inevitable job losses in the fossil fuel industry and go a long way to tackling climate change.Australia’s abundant and cheap wind and solar resources mean we’re well placed to produce the hydrogen a green steel industry needs.

Hydrogen , heavy industry and Prl are the future
