Some more numbers on waste gas..
• Reference scale – Tata steel IJmuiden and Arcelor Mittal Gent – each around 7
million tonnes of steel per year (mta)
• Around 2 ton waste gas per ton steel – total around 14 mta per site - around 10 mta
CO2 (all C to CO2)
• Current use of CO is for power energetic value of CO is low

Considerations – product-market sizes, technology readiness
Market size large enough to absorb (very) large amount of product
from one or more steel mills without significant market disruption
Technology status sufficient to have an outlook to reach full-scale
practice with manageable scale-up route
• CO to Specialty Products – limited market size or immature technology
• Syngas to Methanol – market size ok, technology scale-up feasible
• Syngas to FT Fuels – market size good, technology feasible
• Syngas Fermentation – market ok, technology scale-up ongoing
• Hydrogen through WG shift – market expected, technology scale-up ongoing

Hydrogen through Watergas shift (SEWGS)
• CO + H2O CO2 + H2
• SEWGS (ECN technology) promotes selective shift to CO2 + H2
• 0,32 mta H2; 3,2 mta CO2 avoided; total CO2 capture ready 9,4 mta
• 0,65 billion € investment Capex, positive revenues
• Key technical challenge – bring SEWGS technology to scale of steelworks
Alternatives for H2 production
• Electrolysis PEM, Alkaline or Solid Oxide – price range 3 – 4 €/ton
• Capex/Opex for electrolysis high and not (yet) at needed GW scale
• Conventional – Steam Methand Reforming – 2 €/ton
• Stranded hydrogen – unused industrial sources

Methanol from Syngas – classic route
• EU Market for Methanol – 7,5 mta – of which EU production 2,5 mta
• CO + 2 H2 H3COH
• Classic route – H2 from external source
• 2,36 mta MeOH; 4,9 mta CO2 avoided; total CO2 capture ready 4,7 mta
• 1,5 billion € investment Capex, negative revenues
• CO2 avoidance cost – 136 (H2 @ 3400 €/ton) to 46 €/ton (H2 @ 1700 €/ton)
• Key technical challenge to separate CO – N2

Methanol from Syngas – SEWGS route
• EU Market for Methanol – 7,5 mta – of which EU production 2,5 mta
• CO + 2 H2 H3COH
• H2 from SEWGS – no external H2 source
• 1,5 mta MeOH; 2,1 mta CO2 avoided; total CO2 capture ready 7,3 mta
• 1,4 billion € investment Capex, positive revenues
• Key technical challenge – bring SEWGS technology to scale of steelworks

Fischer-Tropsch Naphtha from Syngas
• EU Market for Naphtha – 450 mta of mixed products
• CO + 2H2 -CH2- + H2O
• 0,95 mta FT product; 3,5 mta CO2 avoided; total CO2 capture ready 4,7 mta
• 1,4 billion € investment Capex, negative revenues
• CO2 avoidance cost – 280 (H2 @ 3400 €/ton) to 160 €/ton (H2 @ 1700 €/ton)
• Key technical challenge to separate CO – N2

Ethanol from Fermentation of CO
• EU Market for EtOH – 5,4 mta
• 2CO + 4H2 C2H5OH + H2O Additional H2 not required
• 0,8 mta EtOH; 5,6 mta CO2 avoided; total CO2 capture ready 4,7 mta
• 1,2 billion € investment Capex, expected negative revenues
• CO2 avoidance cost – 175 (H2 @ 3400 €/ton) to 96 €/ton (H2 @ 1700 €/ton)
• Key technical challenge – scale up to full scale

Conclusions on single site analysis
• Business case depends highly on:
• H2 cost price
• CO2 avoidance costs (future CO2 pricing - not included)
• Investment conditions (not included)
• Each route has technical scale-up challenges – can be overcome
but require focused effort to realize in 2030

Conclusions on single site analysis
• Large Capex needed 0,6 – 1,5 B€ per site
• CO2 avoidance – 2,1 to 5,6 mta @ 46 – 280 €/ton
• Additional clean CO2 produced 4,7 – 9,4 mta – ready for CCU/S
December 21, 2017
• Premium on CO2 costs for an average car
• 840 kg steel in car 2400 kg CO2 (50% scrap in manufacturing)
• Worst case 670 € premium per car of €15.000,=
• Compare to CO2 avoidance offshore wind 220 €/ton in 2013, 130
€/ton in 2016 (factsheet Wind op Zee)

Final remarks
First steps towards circular carbon:
• Large capex-intensive operations
• Technically feasible at large scale
• Economically not straightforward – societal support is essential
