Harri Leppänen: SSAB reducing carbon emissions

  1. 1. Defence´s statement
  2. 2. Our message: 1) SSAB’s hot metal production process generates nearly 600,000 tonnes less carbon dioxide emissions than the European steel industry average 2) Special steels are part of the solution to mitigate climate change 3) There is a lot of on-going activity to research and develop breakthrough technologies to solve the CO2 problem for steel industry 4) Sector based ratings of carbon risk give more reliable and relevant picture Wednesday, October 1, 2014 First Last name3
  3. 3. Steel is all around us! ► Housing and construction sector − 50% of global steel production ► Transport sector (cars, trucks, aviation, shipbuilding and rail) − 16% of global steel production ► Almost 200 billion steel cans of food are produced each year ► 25% of an average computer is made of steel World average steel use per capita has steadily increased from 150 kg in 2001 to 225 kg in 20134

  6. 6. CDP’s sector research for investors Wednesday, October 1, 2014 First Last name7 ► POSCO, SSAB and ThyssenKrupp come top in a CDP League Table that ranks companies in an industry grouping on a number of emissions and water- related metrics relevant to steel companies ► China produces 50% of the world’s steel, but only one of the 15 largest steel producers in China discloses CO2 emissions ► SSAB’s emissions reduction target was evaluated as being among the strongest of the companies assessed ► In our opinion, the sector research approach gives a more realistic picture than the cross sectorial approach of the performance and efforts of the companies to reduce CO2 emissions ► Value chains!

SSAB EcoUpgraded Together with our customers, SSAB continu- ally upgrades steel and equipment designs. SSAB EcoUpgradedsaves CO2 both in steel production and during the full lifetimeof the machine. From the CO2 payback time and onwards, every extra hour brings additional savings. Savings on CO2 MINING TRUCK BOX This heavy-duty mining truck was redesigned and upgraded using Hardox 450 in the tipper body. The weight of the tipper body was reduced by 22%. This reduced the weight by 2.5 tons, which increased load capacity. In addition to this, the life-time of the body is now three times longer than the original, decreasing overall steel consumption and reducing the need for lengthy overhauls. 1,005 2 317,000 “Heavy metal getting lighter” TONS/LIFETIME MONTHS L/LIFETIME SSAB EcoUpgraded Fuel consumption, fully loaded 220 L/h Fuel consumption, unladen 120 L/h Vehicle usage per year 7,300 h/year Weight critical transport 50% Service lifetime 10 years Steel saved by increased wear resistance24,500 kg/lifetime Weight reduction 2,500 kg Total weight upgraded parts 8,600 kg Curb weight 69,000 kg Total payload 91,000 kg Maximum weight 160,000 kg
  10. 10. WE WANT TO DO MORE!
  11. 11. The HYBRIT project ► SSAB, LKAB and Vattenfall announced on April 4, 2016, the launch of a project HYBRIT (Hydrogen Breakthrough Ironmaking Technology) that, if proven feasible, can solve the steel industry’s carbon dioxide challenge. ► The aim is to drastically reduce carbon dioxide emissions from ironmaking by eliminating the need to use fossil fuel for iron ore reduction. The idea is to replace the blast furnaces with an alternative process, using hydrogen produced from “clean” electricity. ► This means that the by-product from ironmaking would be water not carbon dioxide.
