Developing generic tools to assist the design of cation filters for geothermal systems (PERFORM II DK)

The PERFORM II project will drive the development of a new filter technology aimed at cost-effective, sus-tainable, and climate-neutral operation of geothermal heat production. The aim of the project is to reduce environmental impact and operational expenses and support reliable and sustainable geothermal energy production through development and demonstration of innovative cation exchange filters. This scope will be achieved by conducting essential research and development, which requires fundamental understanding of geochemical processes and advanced modelling. The innovative filter technology removes ions to prevent scaling and corrosion and reduces Naturally Occurring Radioactive Materials (NORM) containing waste and may potentially extract valuable metals.
The focus of PERFORM II DK is to develop a complete filter design suite including laboratory tests and numerical models to predict filter performance and to validate the filter technology through pilot tests and demonstrations at geothermal plants. The laboratory program and numerical model activities which will be in focus of the national Danish subproject will inform the selection of filter materials and the design of the filters as well as the piloting and demonstration program.
