Plate heat exchanger to use fossil-free steel

By Mike Brezonick07 September 2022

Alfa Laval has signed an agreement with global Swedish steel company SSAB to collaborate on the development and commercialization of the world’s first plate heat exchanger to be made using fossil-free steel. The goal is to have the first unit made with hydrogen-reduced steel ready for 2023. Alfa Laval said the collaboration to develop the heat exchanger for marine applications is an important step in its journey to become carbon neutral by 2030, which is the same time frame set by IMO for a 40% reduction in carbon emissions from shipping.

Global steel production accounts for 7% of the world’s carbon emissions. With a leading position in high-strength steel, SSAB’s upcoming fossil-free steel made with HYBRIT technology will be a breakthrough for the industry as it transitions to more sustainable operations. The impact of fossil-free steel will be significant in Alfa Laval marine plate heat exchangers, which can be found on countless vessels worldwide.

Alfa Laval’s heat exchanger portfolio includes plate heat exchangers that are suitable for both traditional and alternative fuels. They can be used in applications from engine and lube oil cooling to LPG cargo condensing and fuel cells and their design minimizes fouling and maximizes heat transfer capabilities, the company said.

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

“We’re proud to welcome Alfa Laval as a partner and look forward to jointly exploring ways forward to mitigate climate change,” said Martin Lindqvist, president and CEO of SSAB. “With this collaboration we´re reaching new segments, and hopefully inspiring a whole new range of customers.”
