This project will involve the implementation of a heat recovery system at the Rio Tinto / Alcoa Strathcona Works’ (SW) manufacturing facility in Edmonton.  This system will convert high grade waste heat to approximately 24 MW of emission free electricity via a steam cycle, enabling advanced pollution controls systems to be utilized onsite. By reducing the temperature of flue gasses, an integrated Flue Gas Desulfurization (FGD) system and fabric filter can be implemented to reduce SOx, NOx, and particulate emissions from the facility. Benefits of the project include new revenue streams through electricity sales and GHG credits as well as reductions in air emissions. This technology would also allow for a possible production increase at the SW facility. Pending final investment decisions, the zero emissions electricity from the proposed waste heat to power plant will offset higher intensity sources of power from the Alberta electricity grid, providing a steady income stream for the facility, and will reduce the SOx and NOx emissions from the facility.

The project estimates GHG reductions greater than 100,000 tCO2e/yr once fully implemented.
