The new technology proposed in DeepU\u00a0will revolutionise the geothermal energy sector,\u00a0increasing the accessibility of deep geothermal resources for low-carbon heating and power generation.\u00a0<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>The unique technology developed and tested involves a laser propulsion drilling method with cryogenic gaseous flushing for cooling the laser drill head. In case a glazed layer is formed on the borehole walls, the obtained systems are physically isolated from the surrounding rocks and ready to be developed immediately after drilling. The increased drilling speed and the lack of casing and production liner in the reservoir section will substantially reduce well drilling costs.<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>So, let\u2019s recap the results of the\u00a0first year\u00a0of activities.\u00a0<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>The most suitable cryogenic gas has been selected based on the required qualities: availability, low price, and thermodynamic properties that allow the gas to remain in a liquid state over long distances to reach the base of the well during drilling.\u00a0<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>New concepts for drill string and drilling platform design are in development. The novel drill string guides the laser beam down inside the inner drill string while transporting the liquid cryogenic gas downward to the drill head. The drilling tower and platform house the laser and the rotary drilling systems, the liquid cryogenic gas tank and the ash extraction plant with the gas separator and recycling system.\u00a0<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>A press container has been set to perform the first laboratory tests with the novel lightweight laser and gas processing drill head and was equipped with monitoring devices. In a preliminary drilling test, a 3D-printed titanium laser processing head\u00a0created precise and symmetrical holes in\u00a0granite, limestone and sandstone samples. In addition, constant rates of penetration upwards of 20m\/hr have been achieved, with relatively low energy inputs and no component wear that would be associated with mechanical engaging drilling methods.\u00a0<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>Health and Safety aspects related to site development, drilling operations and completion, as well as environmental and economic aspects of the DeepU technology uptake are under analysis to achieve regulator acceptance and commercialisation.<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>DeepU has been funded under the EIC Pathfinder programme (G.A. 101046937) by the European Commission as part of Horizon Europe.
