This Friday I'm defending my PhD thesis 'Steel Beyond Coal'.
With nearly 6 years of research on steel decarbonisation coming to an end, here comes a very long 🧵about steel, coal and what we can do radically reduce carbon emissions in line with a just transformation.

First things first. Steel is iron, carbon, and alloys such as nickel and chromium. Yes, carbon is per definition a part of steel. But let this not distract you, this does not mean we cannot phase out fossil fuels (quite the opposite).
Decarbonising industry is critical to EU climate targets and to our economic competitiveness and autonomy. Our new report shows exciting momentum in industrial #cleantech, but also critical policy gaps: materialeconomics.com/publications/s… (1/8)
We found 70+ projects already in the pipeline across Europe, using breakthrough technologies with the potential to sharply reduce industrial GHG emissions. (2/8)
Just 5 of these breakthrough technologies could cut CO2 emissions from steel, chemicals and cement production by up to 70%, bringing those industries much closer to #netzero. (3/8)
Do you already know our #GlobalSteel Transformation Tracker? Our new online tool provides insights on the status quo of #steelproduction worldwide, to the necessary reinvestments, announcements of #greensteel production before 2030 and more. Ready for some insights? 👇 #COP26 1/7
Where are the steel centres located? Are blast furnaces, integrated direct reduced iron or electric arc furnace used for production? Our interactive map with data from @GlobalEnergyMon/@caitlinswalec lets you explore steelmaking around the world. 2/7
Our #GlobalSteel Transformation Tracker visualises the required reinvestments of a country’s #blastfurnace fleet from 2021-2050. That most of the blast furnaces will reach the end of its working life before 2030 is an opportunity to replace them with low-carbon technologies. 3/7

#India recently announced the National Hydrogen Mission & there's growing interest among leading industry players in #greenhydrogen.
But why is green H2 significant for India's #energytransition?

#pressrelease: bit.ly/3l3b8fc
In a new study, we examined how #greenhydrogen can help in cleaner steelmaking. We found that:
▶️9% blend of #green H2 in steel making would ⬇️India's emissions footprint by 68%
▶️This #greensteel would be competitive with upper range of conventional steel costs at current rates
▶️9% blend of #green H2 in steel making would ⬇️India's emissions footprint by 68%
▶️This #greensteel would be competitive with upper range of conventional steel costs at current rates
If #greenhydrogen costs fell to 1.3-2.2 USD/kg from the current 4-4.5 USD/kg, steelmaking based entirely on #green H2 could break even with #coal-based processes in #India. Globally, electrolyser manufacturers have already committed to a green H2 cost of 1.5 USD/kg by 2025.
🆕 Stoked to announce the release of @globalenergymon’s newest report, Pedal to the Metal: No time to delay decarbonizing the global steel sector. 36 pages details here, but I’ll share a few highlights.

The steel industry faces a big choice: move away from dirty, inefficient plants 🏠OR risk climate goals and up to $70bn stranded asset risk 💰 (2/9)
Over 60% of global steelmaking capacity in the GSPT uses the BF-BOF method, which is a difficult and expensive process to decarbonize because of the use of metallurgical coal (3/9)
