A reduction of flow resistance in pipelines will allow the installation of smaller pipe diameters, smaller pumps, geothermal well and other system components. This will reduce the costs of materials and costs of excavating and limit nuisance in the in the residence environment. DRAGLOW is funded under the Dutch MOOI Innovation program, a Dutch government subsidy scheme that stimulates the development of innovations of sustainable, reliable and affordable energy systems.
A promising concept to reduce frictional drag in pipelines is by injecting specific molecules to the flow, known as Drag Reducing Agents (DRA). This concept is developed and successfully applied in the petro-chemical sector and may offer substantial reduction of costs for the infrastructure of the emerging geothermal district heating sector. In the Dutch Research Centre for Sustainable Geo-energy in Rijswijk (RCSG), existing drag reducing molecules will be tested under the conditions similar to the operating conditions in geothermal district heating systems. The usage of molecules produced with natural green chemistry is an essential part of the goal of the project. Models will be developed to design innovative solutions to maximize the advantage of low drag circulating systems for multi-source heat grid systems addressing cost challenges that the emerging sustainable heat sector is facing.
In DRAGLOW, a sector-wide system development approach is applied that will be built based on the high level expertise of the consortium partners from both the public and the industrial sector including local governments, geothermal heat producers, heat distributors, material suppliers, service providers, well designer, university and research institutes. The partners of the consortium are proud to contribute to energize sustainable heat supply projects, social acceptance and to share the knowledge of this project with interested parties.
The DRAGLOW consortium consists of TNO, ECW Energy, Roemex Ltd, Nouryon NV, TU-Delft, Enertrans BV, Well Engineering Partners, Wayland BV., Nijkamp Aanneming BV, Municipally of Rotterdam and Municipally of Amsterdam. The project will run for 3 years.
