LEG-DHC - Large-scale climate neutral Energy Geostructures in District Heating & Cooling systems/networks

Project Description

Previous investigations over the decades have significantly advanced the technological readiness level (TRL) of some EGS (thermo-active piles) to a higher 4+ level with a number of pilot sites. Despite this well-known interest, there still remains some technical barriers on the route of the implementation and integration of EGS at a large scale as the below: • The lack of visibility on positive thermal and mechanical feedback for the stakeholders • The integration of EGS into a district heating system at the regional scale • The collaborative operation and management of geothermal energy, solar and other local energy sources for a climate neutral regional community To breakdown the aforementioned barriers, this project will aim to: - Show the global feasibility in terms of thermal efficiency and mechanical impact on existing complex infrastructure. In particular, the energy production, carbon reduction and other existing data will be analysed to demonstrate the environmental protection over previous efforts. - Provide a structured, easily accessible and clear database presenting feedback on thermomechanical behaviour, energy performance, overall efficiency, durability, etc
