A new PUSH-IT deliverable explores how different models can be brought together to simulate the interactions between all different parts of the heating network. But what exactly is cosimulation, and why is it so useful for underground thermal energy storage? We spoke to deliverable author Ergin Kükrer to find out and to hear about the challenges the researchers faced along the way.
A few weeks ago, several researchers from the PUSH-IT consortium attended and presented at the World Geothermal Congress. One of them was Ergin Kükrer, who talked about cosimulation and digital twins for HT-ATES systems.

As part of the Push-It project, a new hydrogeological borehole at Litoměřice has been established to monitor groundwater flow and quality. Located at a future site for underground heat storage, the borehole will play a key role in observing groundwater velocity, flow direction, and chemical composition at depths ranging from 100 to 400 meters.
Vit Peresty takes us through the drilling of a hydrogeological borehole at the RINGEN research center at Litoměřice.
A cored borehole is currently being drilled on the RINGEN research center site, which will provide rock samples from depths ranging from the surface to 550m. Their analysis and geophysical measurements directly in the borehole will provide valuable information for planning underground heat storage in boreholes of various depths.
Over the last months, two types of logs have been performed on the site in United Downs. Level loggers have been installed in some mine shafts and temperature logs have been performed.
One of the key challenges faced by the PUSH-IT project is the complex regulatory landscape for High Temperature Underground Thermal Energy Storage (HT-UTES) technologies. This varies significantly across different countries.

This is what an interdisciplinary group of researchers recommend in a newly published chapter. They argue that inclusive, early and continuous societal engagement should be prioritised to maximise the benefits of geothermal technologies.
In September, during the PUSH-IT General Assembly in Darmstadt, project members participated in a workshop on local stakeholder engagement and communication.

The long awaited drilling of two research wells began last week in Litoměřice, starting with the core well of 550 meters deep. Litoměřice belongs to one of the six pilot sites in Europe where research on the use of the underground for seasonal thermal energy storage is being carried out.
How does underground thermal energy storage influence microbial diversity?
This is one of the topics being researched using water quality sampling. Maud Watkinson and Sylvain Stephant, researchers at French Geological Survey (BRGM), recently visited the PUSH-IT pilot site in Delft to tackle this question.
This year we will see many new developments in the PUSH-IT project. We have asked the leads of the pilot sites to reflect on the first year of the project and to share their New Year’s resolutions.
There is a high heat demand in winter, while we produce heat that is not used in summer. We call this the seasonal mismatch in heat supply and demand.
How can we collaborate to overcome the seasonal mismatch between heat demand and heat production using underground heat storage? This was the main question we addressed in Prague and Litomĕřice during the PUSH-IT General Assembly.
Welcome to our new series, “Meet the Scientist,” where we dive deep into the research and personal background of the scientists working on the PUSH-IT project.
