Steelworks' CO2 to grow algae

Tata Steel is undertaking a project to see if CO2 emissions from its Port Talbot site can be used to grow algae. The collaboration known as ACCOMPLISH (Algal Carbon Capture and BiOMass-Linked Supply cHain) is part of a wider Swansea University project, EnAlgae.

It plans to access the capacity for natural algae to use carbon dioxide as a nutrient for growth.

Dr Alla Silkina, from Swansea University, said: "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."
