Tata Steel and Swansea University are developing technology to manage carbon dioxide produced as a by-product of steelmaking operations.

Known as ACCOMPLISH – or Algal Carbon Capture and BIOMass-Linked Supply Chain – is part of Swansea University’s wider EnAlgae project and is based at Tata Steel’s Port Talbot steelworks.

The ACCOMPLISH project analyses the capacity for natural algae to use carbon dioxide as a nutrient for growth and contributes towards the steelmaker’s commitment to reducing unavoidable carbon dioxide emissions from its manufacturing operations.

Tata Steel’s technical director, Martin Brunnock, said that the company was committed to further improving the sustainability of its processes. “It is projects like this, with leading academic partners, such as Swansea University here in Wales, which are making us leaders in the field of sustainable steelmaking,” he said.

Swansea University’s Dr. Alla Silkina said that the ACCOMPLISH project was an important example of how working closely with industry can yield practical results for researchers and businesses.

“We have been able to use the Port Talbot by-product streams as an algal growth nutrient. In addition, a biomass is cultured which can be used for energy (biomethane) production or potentially as a fish feed,” Silkina said.

The wider EnAlgae project is led by Swansea University and funded by the European Union under the INTERREG IVB North West Europe programme. EnAlgae unites experts and observers from 7 EU member states to determine the potential benefits of algae as a future sustainable energy source.
