    TKI Watertechnology for innovation projects as Blue Battery and RedStack (Reverse ElectroDialysis)

    The Top consortium for Knowledge and Innovation in Water Technology (TKI) offers a support program to bring early stage innovation to market. By the hand of two TKI supported energy from water projects the innovation landscape is presented and the support that can be expected from the TKI to successfully guide innovation from a scientific idea to ultimately the market.

      Value creation through collaboration the Valkenburg case: Integration of wastewater heating and drinking water solutions.

      Climate change and the transition away fossil fuels are key challenges for the stakeholders of Rijnland and Dunea. Former airport Valkenburg is one of the largest development sites in our region with approximately 5000 houses. We believe that collective energy systems and separate wastewater collections are key elements in creating a sustainable community, providing cossavings and enabling future innovationsWe co-developed this solution by applying new ways of collaboration and organisation.

        A revolutionary approach towards exploiting lunar energy on nuclear scale.

        To be able to comply with the Paris Agreement and often for geopolitical and economic reasons too, many governments are switching from fossil fuels to sustainable energy resources. “Lunar energy” is the only 100% sustainable energy resource that is climate-independent and therefore can provide a reliable baseload in the future electricity production of a nation. Dynamic Tidal Power (DTP) is the only available technique that can exploit this energy resource on a meaningful large scale (i.e. many GW’s installed power).

          Drinking water distribution networks: An emerging resource for thermal energy recovery

          Drinking water distribution networks (DWDNs) have huge potential and significance for thermal energy recovery in the form of cold. This can provide enough cooling for buildings and spaces with high cooling requirements and is helpful in reducing carbon footprints by abandoning traditional cooling methods. This study showed that recovery of cold from microbial safe water of high quality by heat exchangers, at temperatures of 15, 25 and 30oC after the heat exchanger, provided 54,225 and 317PJ/y of energy respectively. Furthermore, in subsurface the temperature of water within DWDNs, after having passed the heat exchanger, will be equivalent to surrounding soil temperature within 1km. From human health perspectives, opportunistic pathogenic bacteria like Legionella will not regrow after exposure to cold recovery at these three temperatures.

            Licence for industrial growth: Full scale cases of water reuse

            Water scarcity and stringent discharge standards have raised industrial interests in wastewater reuse. By incorporating membrane technology, industries can be self-supporting in water and maintain sustainable growth. Three full-scale water reuse cases are described from the cosmetics, meat, and cartons industries to reflect the growing demand of water reuse in industrial sectors. 

              Floating solar at Evides: A water quality perspective

              Application of floating solar panels is especially suited for the Netherlands, given the limited availability of land (surface area). Evides Water company owns and operates several open storage basins which can be used for installation of these panels, but this can affect naturally occurring processes and water quality. In this research we evaluate possible effects based on a theoretical approach following the AMSD method (Analysis of Microbiological Safety of Drinking water). Besides the water quality issues, the research will also investigate possibilities of applying alternative storage possibilities using hydrogen.

                Self-sustaining system of biomass energy utilising local bio-resources at wastewater treatment plants

                Iiyama city is located in a mountainous area of Nagano province, Japan and has a population of around 20,000. It has been actively cultivating mushrooms as a local industry. Waste mushroom beds generated as residues of mushroom cultivation are partly used as fertiliser and fuel. However, due to the decrease in agricultural land area, its consumption for effective use is reduced. Moreover, in addition to waste mushroom beds, biomass such as rice husks and harvested grasses are also generated from the city, and its effective use is also an issue. Meanwhile, three sewage treatment plants in the public sewage project are in operation in the city. However, due to the recent declining population, inflow sewage volume is expected to decrease in the future. It is expected that the facilities may have margin, something that was not expected when present sewerage plan was established, because of the declining service population. We evaluated the feasibility to introduce mixed processing.  Mixed processing here means the treatment of the mixture of sewage sludge and the agricultural waste.
