Summary
Projek logo Ice Storage II
The aim of the follow-up project ErdEis II is to prove the economic and technical feasibility of this technology with the realization of a new type of ground ice storage in a pilot project and thus to make a contribution to emission-free, regenerative heat supply in Germany. The research focus is on the large-scale implementation of a ground ice storage system for the heating and cooling supply of a neighborhood in two variants. The distribution of the heat/cold with the help of a cold local heating network also plays a decisive role here due to the complex hydraulic integration of the most diverse sources and sinks. The tool for the planning and design of the ground ice storage developed within the scope of the targeted research project allows the transfer of the results to other construction projects and thus a high multiplication potential. The ground ice storage serves as a heat and cold source for heat pumps to supply the buildings in the planned quarter. Advantages of the ground ice storage are the significantly higher storage density compared to classical geothermal fields and the possibility to shift heat and cold seasonally. Due to the low temperature level, the storage can be used as a source of cooling all year round. In order to be able to investigate a wide variety of application scenarios, two variants are being implemented. In order to be able to fully record the operating mode of the ground ice storage, a geothermal measurement field is implemented in the ground. This enables the comparison of the earth ice reservoir with geothermal fields from other research projects. The knowledge gained about the icing of the earth will be made available to the public and other stakeholders from research and politics in the form of publications and lectures. Through the targeted dissemination of the developed design tool, the technology should find general acceptance and spread.

Project progress
ErdEis II is scheduled to run for three years and is divided into five work packages with a total of 19 sub-packages. The sub-project of Schleswiger Stadtwerke comprises the technological and economic planning, implementation and commissioning of the earth ice storage facility and the cold local heating network (WP 1), the development of billing models for future construction projects (WP 3.3), the development of novel components (WP 4) and the technical project coordination (WP 5.1). The subproject of BUILD.ING Consultants + Innovators GmbH initially deals with the support of the planning of the ground ice storage and the cold local heating network as well as the commissioning (WP 1), the planning of the metrological recording (WP 2), the cooperation in the development of novel components (WP 4) and a practical design tool for ground ice storage (WP 5.2) as well as the scientific project coordination (WP 5.1). The sub-project of the Friedrich-Alexander-University Erlangen includes the planning and implementation of the metrological recording of the ground ice storage (AP 2.1) as well as the investigations of non-technical obstacles in the use of ground ice storage (AP 3). The sub-project of the Technical University of Dresden focuses on the computer-aided planning optimization of the quarter (WP 1.1) as well as the support in the creation of the practical design tool for ground ice storage (WP 5.2). In its sub-project for the follow-up project ErdEis II, the Rheinisch-Westfälische Technische Hochschule Aachen is concerned with the computer-aided planning optimization of the cold local heating network with the integration of a wide variety of producers and consumers and variable interconnection of these (WP 1.1).
