DeepU is a project that has received funding from the European Union's Pathfinder programme under grant agreement No. 101046937. The overall aim of DeepU is to create a deep (>4 km), closed-loop, vitrified, waterproof, non-cracked U-tube heat exchanger by combining laser and cryogenic gas into a single technological drilling solution at laboratory scale in different rock types. The developed fast and effective drilling technology that liquefies and vitrifies the rocks leaves the borehole ready for heat exchange immediately after drilling. The demonstration at the laboratory scale produces the information required for assessing the technological, environmental and economic sustainability and defining the potential and commercial attractiveness of the proposed solution.
