AST Technology can assist in the design and development of processes that reduce the need for carbon in steel making processes, by using hydrogen for reduction of ores which produces water vapor instead of greenhouse gases.


Steel is a major building block of our modern world, but the way it’s made – using coal – is making climate change worse.

Steel-making requires stripping oxygen from iron ore to produce pure iron metal. This is done using coal or natural gas in a process and releases CO2. Green steel is made by using hydrogen, rather than coal, to strip the oxygen out of iron ore and the by product is water rather than CO2.
