Sweden aims to become carbon neutral by 2045. To support the ambition, Sysav has explored the possibilities of introducing Carbon Capture and Storage at Sysav’s waste-to-energy plant in Malmö, Sweden. With this new initiative, Sysav has a vision to make Sweden carbon neutral already by 2030.
With the introduction of Carbon Capture and Storage, Sysav aims to reduce carbon dioxide emissions from the plant by approximately 90 percent. A possible implementation of Carbon Capture at Sysav’s waste-to-energy plant will have a significant reduction effect on the region’s CO2 emissions.
The investigation of the conditions of implementing Carbon Capture technology at the waste-to-energy plant was the first step to be able to not only reduce carbon dioxide emissions, but also to achieve negative emissions in Sweden.
Ramboll contributed to Sysav’s vision by conducting a feasibility study for a full-scale Carbon Capture solution for the plant with a capacity of approximately 500,000 tonnes CO2 per year. The Swedish Agency’s Climate initiative “Industriklivet” partly funded the feasibility study.
Ramboll is leading the way for Carbon Capture technologies
The feasibility study aimed to identify the most advantageous technology choices for Carbon Capture, process, and energy integration as well as to make a design adjustment of the most important conditions for establishing a unified Carbon Capture and Storage value chain for Sysav’s waste-to-energy plant. In addition, Ramboll investigated the total economic consequences of the establishment and commissioning of CO2 capture, transport, and final storage.
Ramboll’s leading Carbon Capture expertise team knowledge shared and provided technical assistance to highlight which Carbon Capture technologies are suitable for Sysav to implement at their waste-to-energy plant to reduce CO2 emissions.
The design basis of the necessary technical and economic data was developed to create the design basis for the future Carbon Capture plant, and a comprehensive Carbon Capture technology screening identified the most suitable Carbon Capture technologies to use. An amine-based technique with monoethanolamine (MEA) solution and a Hot Potassium Carbonate (HPC) solution were identified as the two most promising technologies.
A comprehensive economic and legal analysis was carried out, which included the overall economic consequences of establishing and commissioning a potential Carbon Capture plant and an assessment of the regulatory conditions with the purpose of assessing whether Sweden’s legislation supports the use of Carbon Capture in Sweden.
