The objective of PERFORM II is to develop a new filter technology to improve geothermal plants for a cost-effective and climate-neutral heat supply. To this end, operational issues such as scaling and corrosion and associated Naturally Occurring Radioactive Materials (NORM) must be mitigated. This will be achieved by laboratory experiments on filter material, examining filters' design, and designing and building a mini-plant for tests under plant operating conditions.

The mini-plant will be portable and used for bypass experiments at two geothermal plants in the Netherlands and Germany. Finally, an assessment of the environmental footprint of the filter technology and an economic (market and cost) analysis will be combined with the technical results to produce a roadmap to upscale and commercialise this filter technology.
