The 6-month test campaign of the HIsarna pilot plant in 2016 will establish whether the new technology can produce molten iron in a stable way over a sustained period of time. The EU’s support represents nearly a third of the 25 million euro test costs next year.
If the technology is viable and can be scaled up successfully, it would enable further resource efficiency improvements in steelmaking – using the world’s limited resources in a more sustainable way while minimising impacts on the environment.
Steel companies would be able to use a wider range of raw materials, including recycling materials, and the technology would lead to 20% lower CO2 emissions. If successful, the HIsarna technology could deliver greater environmental and economic sustainability 10 to 15 years from now.
Tata Steel European operations chief executive Karl Koehler said: "We welcome the European Union’s support for this promising and potentially groundbreaking project. The development of this technology still has a long way to go, so support from the EU is vital."
The main advantage of HIsarna technology is that it eliminates two energy-intensive preparatory stages in iron making. There is no need to cluster fine iron ore into sinter or pellet or to convert coal into coke, as there is in conventional blast furnace iron making.
"The steel industry is an integral part of the circular economy, striving for zero waste, 100% recycling and the reuse of materials," Mr Koehler added. "Hisarna could play a future role in the creation of a more sustainable low-carbon European economy.
"Tata Steel and its partners have continued to invest in this potentially breakthrough technology despite some very challenging economic conditions in Europe. But future phases of HIsarna’s development will require very substantial investment that will exceed what the project partners can provide themselves and indeed what current public innovation frameworks are likely to be able to fund.
"We need the European Union’s continued, long-term support for the HIsarna project. If next year’s tests are successful, the following stage would be developing, constructing and testing an industrial-scale plant at a cost of 300 million euros."
Next year’s test campaign is the fifth series of tests since the pilot plant was built in 2010. Tata Steel and its project partners aim to prove the facility can produce liquid iron for sustained periods. The previous four campaigns each lasted about two months, during which iron was produced for a maximum of three days.
Another key objective is to establish HIsarna’s potential CO2 savings. There will also be tests using various types of raw materials, scrap and by-products from the steelmaking process.
The EU’s support is part of its Horizon 2020 SILC-II programme.
If HIsarna becomes commercially available on an industrial scale, steel producers could lower manufacturing costs, reduce energy consumption and CO2 emissions and take resource efficiency to the next level. An additional advantage is that HIsarna reduces the emissions of fine particle dust and dioxins, as well as nitrogen and sulphur oxides.
HIsarna is a Tata Steel and Rio Tinto initiative, with close cooperation from European steel producers ArcelorMittal, ThyssenKrupp and Voestalpine and technology supplier Paul Würth.
