Critical Challenge Ahead:
Transforming the Iron and Steel Industry
Today's main way of making iron and steel remains the blast furnace. The challenge of blast furnace based iron and steel making is that large amounts of CO2 are released into the atmosphere during the process:
For each ton of finished steel, more than 2,000 kg of CO2 are emitted.
With total global steel production expected to exceed 2bn tons of finished steel per year by 2030, blast furnace based iron and steel making is not sustainable.
Our Solution 1:
DRI & Green Hydrogen
An alternative to blast furnace based iron and steel making is the so called Direct Reduced Iron (DRI). In the DRI process, iron ore is deoxidized in a reactor under high pressure with natural gas. This results in lower CO2 emissions.
In Danieli’s modern Energiron technology which we are using, CO2 emissions can be further reduced if natural gas is replaced by green hydrogen.
The challenge of green hydrogen is its cost. Even if powered by the most efficient renewable energy source, the full use of green hydrogen in the DRI process leads to an increase of more than 300 USD per ton of steel.
Therefore, we are taking the use of green hydrogen one step at a time. Our initial target is to use up to 25% of green hydrogen in the DRI process.
Our Solution 2:
EAF & Renewables

Our green steel will thereby help to save nearly 4 million tons of CO2 annually.
That is equivalent to:
Planting 200 million Trees a year
A forest as large as the wider Bangkok area
Neutralizing all CO2 emitted annually
by all private vehicle traffic in Singapore
