New Geothermal Technology to Revolutionize Urban Heating and Cooling Systems!
Researchers assessed deep and shallow geothermal resources and waste heat from an industrial dairy plant to supply renewable heat for industry and urban areas. They found that a high-temperature heat pump could utilize geothermal heat from a feasible reservoir with temperatures between 129 and 146 °C. By measuring waste heat from the dairy plant, they identified that 25% of waste heat from a specific process could meet the energy demand of a nearby urban heating and cooling grid. A borehole heat exchanger field with heat pumps was simulated to efficiently store and distribute the geothermal and waste heat. The study concludes that the entire process of converting high-temperature heat for industry into low-temperature heat for urban areas is feasible at the site.
