Adoption Trends & Obstacles
Key Messages | Steel's Future
- Reaching net zero by 2050 would require a ~25% emissions reduction by 2030
- Policymakers can and should step in to assist with green technologies, such as H2 Green Steel’s and Electra’s new generation plants
- The focus should be on creating low-cost, low-carbon electricity and on driving down capital costs for new technologies
- A production tax credit for low-emission iron would support electrolysis as well as green H2
- Time is of the essence, as Asia’s large fleet of high-carbon legacy blast furnaces (~75% of global iron production) are due for costly relining in the next 10 years. This presents an opportunity to instead invest in newer, greener technologies

Observations
- The International Energy Agency (IEA) expects limited decarbonization progress until 2030, with only a slight increase in scrap EAF production and first production using green hydrogen and electrolysis
- Scrap steel electric arc furnace (EAF) is expected to become the most used production method for steel by 2050 ─
taking 46% market share - In the IEA’s scenario, the remaining 54% is split between green hydrogen, electrolysis-based production, and CCUS-equipped production
- It should be noted that the effectiveness of carbon capture, utilization, and storage on blast furnaces is still challenged and debated within the steel industry
Mission Possible Partnership, on the other hand, expects green hydrogen and bioenergy to drive decarbonization
Notes:
- BAU = Business as usual, assuming production route mix as of 2020 maintained; Increased scrap steelmaking refers to increase in both Scrap EAF production and use of scrap in primary production routes;
- DAC = direct air carbon capture. Sources: Mission Possible Partnership Making Net Zero Steel Possible (2022).

Stranded asset risk
- Existing conventional plant equipment worldwide has an average age of only 13-14 years (<50% of the typical lifetime of 40 years)
- Overhaul of production routes for to transition to Net Zero could result in $345-$518B of stranded assets
- Stranded assets expected to be concentrated in Asia, particularly China and India
Infrastructure and equipment risk
- Green infrastructure, especially zero-carbon electricity generation and hydrogen production capacity, have to expand significantly to enable the steel industry to transition.
- Electrolysis technologies are nascent –production equipment still needs to be proven successful at mass scale
Transport and storage cost of CO2
- As it relates to global carbon storage, demand is outpacing storage space development.
- Without increased efforts to accelerate CO2 storage development, the availability of CO2 storage could become a bottleneck to CCUS deployment, alongside aforementioned drawbacks, like unproven technology.
A consensus definitionfor green steel and iron
- Pressing need for unified definition of green steel and green iron, as diverse approaches are currently being pursued
- Having shared definitions is crucial, but of course, no single definition can accommodate all perspectives
Dwindling steel workforce
- Insufficient educational and training opportunities for the steel industry’s workforce
- Declining interest in younger generations to pursue careers in this field
- Those that are interested typically gravitate toward green steel, meaning employees in the grey steel space are dwindling
Limited governmental support
- Transitioning to new production technologies expected to cost $4.4T over ~30 years
- Production costs per tonne of steel could rise by 30% driven by higher OPEX and required CAPEX of green hydrogen and CCUS technologies
- At present, there is limited governmental support to incentivize producers to adopt greener production routes
