Feasibility study of power centre Grindsted


The pollution under the town of Grindsted is defined as one of Denmark’s 10 Generation Pollutions. The water pollution is extensive and runs under most of the town. Therefore, GEV, together with the Region of Southern Denmark, has a declared goal of establishing a sustainable clean-up of the pollution via sector coupling, extracting surplus heat for consumers and supplying purified cooling water to the city’s businesses.



The key technology behind ‘Kraftcentrum Grindsted’ is electrolytically stimulated purification of the generation pollution. This pre-project will therefore, based on pumped contaminated water from the city of Grindsted, uncover the efficiency of the electrolytic purification method and provide a qualified estimate of the economics for large-scale production.

The concept and method is a newer purification method, and despite being well described in the research literature, only a few companies have commercialised the technology. The technology is an electrolytic-based pump-n-treat solution that can break down the contaminant and generate purified water of a quality that can be used for industrial cooling water.

The electrolytic process thus combines multiple degradation mechanisms, which is unique to the method and makes it highly suitable for handling mixed contaminants.



The pre-project will generate data and experience that will be used to design and plan subsequent on-site pilot testing of the method on an existing well.

The goal of the project is to develop a technology powered by locally produced renewable energy that combines purification of contaminated water and utilisation of low-quality waste heat as a contribution to the district heating system in Grindsted.
