Verkkonow, manchester researchers are working with the british geological survey and university of bristol to explore whether this potential can be realised in the uk. Verkkotherefore, this review discusses and analyzes the potential of geothermal energy as an alternative energy source based on the geothermal. Verkkoenergy is extracted from two main types of deep geothermal systems: Hydrothermal systems, which directly use heat only, and petrothermal systems (also referred to as. Verkkogeothermal energy, a clean baseload resource independent from weather conditions, could significantly contribute to energy needs, improved air. Verkkogeothermal resources have the potential to provide up to 150 gwe of sustainable energy by 2050. However, the key challenge in successfully locating. With an estimated heat potential of 328 x 1018 j th [2] and a power potential of 2280 mw e [3], geothermal energy resources.
