Alfa Laval decided to work with Swedish steelmaker SSAB to build the world’s first plate heat exchanger made with fossil-free steel.


SSAB’s new HYBRIT steelmaking process uses hydrogen for the direct reduction of iron ore rather than traditional blast furnace processing. If the hydrogen comes from “green” sources – as SSAB predicts – the process results in sponge iron with no CO2 emissions along the way. The company plans to have its first demonstration facility in Gällivare, Sweden operational by 2026.


Globally, the steel industry accounts for around 7% of all carbon emissions, and its share of total life cycle emissions from shipyards and marine suppliers – which use large amounts of steel – is considerably higher. high.


Alfa Laval has signed an agreement with SSAB to collaborate in the development and commercialization of the world’s first plate heat exchanger to be made from fossil-free steel. The goal is for the first unit made with hydrogen-reduced steel to be ready by 2023.


Alfa Laval says the deal is part of its goal to become carbon neutral by 2030 – the same deadline set by the IMO for a 40% reduction in carbon emissions from shipping. The company manufactures a wider range of plate heat exchangers for the marine industry than any other supplier, so the agreement could have broad applicability.


“Our marine plate heat exchangers are already key to onboard decarbonization, thanks to their superior level of energy efficiency,” says Peter Nielsen, president of Alfa Laval Marine Separation & Heat Transfer Equipment. “Through our collaboration with SSAB, we will minimize their total carbon footprint. Made with fossil-free steel, plate heat exchangers will be as smart in production as they are in operation.


In addition, Cargotec and SSAB have also agreed to work on introducing fossil-free steel to the cargo handling industry. Last year, the two companies signed a letter of intent to expand the use of SSAB fossil-free steel in Cargotec’s cargo handling equipment.
