Today in the Lab – Tomorrow in Energy?
Highlighting research projects under development in the Technology Collaboration Programmes
What is the aim of this project?
Borehole heat exchangers, used in shallow geothermal energy generation, interact with the ground in highly complex ways. Ensuring the consistency of such installations requires steady quality assurance throughout design, construction and operation. This project aimed to examine failures of such geothermal plants from technical, economic and ecological viewpoints. Subsequently, the project developed solutions to improve the installation and maintenance of borehole heat exchangers.
How could this technology be explained to a high school student?
Borehole heat exchangers interact with geothermal heat in shallow subsoil layers down to about 400 m below the surface of the ground. They consist of a heat exchanger inside a borehole, in which a heat-carrying fluid circulates. They can be used in heating or cooling systems, or for long-term underground heat storage. To ensure economic feasibility and ecological compatibility, such systems need to be properly designed and assessed throughout their life.
What is the value of this project for society?
At what stage of development is this project?
The project started in October 2016 and ended in March 2020. It was closely related to the Energy Storage TCP Annex 27. The project’s results will be published by the end of 2020 and included in the European standardisation work of CEN TC 451 (working group 2), which is in progress.
What government policies could bring this from the lab to the market?
About the Technology Collaboration Programme on Energy Storage (Energy Storage TCP)
Established in 1978, the Energy Storage TCP facilitates research, development, implementation and integration of energy storage technologies to optimise the energy efficiency of all kinds of energy systems and enable the increasing use of renewable energy. The Energy Storage TCP enables high-level co-ordination in research, development, dissemination and market deployment of energy storage solutions.
