Shallow Geothermal Energy: An Emerging Technology
2018Shallow geothermal energy systems use the upper few metres of the ground below the surface to provide space heating and cooling efficiently. Well-designed systems render year-round coefficient of performance (COP) of about four or more. In closed-loop geothermal systems, high-density polyethylene (HDPE) or cross-linked polyethylene (PEX) pipes are ...

Distribution characteristics and utilization of shallow geothermal energy in China
Energy and Buildings, 2020Abstract This paper summarized the shallow geothermal resources within a depth of 200 m in China. This geothermal resource is divided into five regions based on the geological structures, geomorphology, geology, and hydrogeology. The recoverable amount of shallow geothermal energy (SGE) is equivalent to 7 × 1012 kg of standard coal in a survey area ...

Shallow Geothermal Energy in Denmark – Current Status and Trends
Proceedings, 2012Shallow geothermal energy is a renewable energy source with large potential for reducing CO2 emissions. The application in Denmark, however, is limited compared to e.g. Sweden and Germany. Preliminary estimates indicate that the energy extraction from a 100 m closed loop borehole may be up to 40% lower for an unfavourable geological situation compared ...

High Enthalpy Shallow Geothermal Energy: The Anomaly
The SAGE4CAN project focuses on investigating the shallow geothermal potential of the Canary Islands. During the project execution in 2021, the Tajogaite volcanic eruption took place. This eruption resulted in the deposition of lava flows, totaling approximately 200 million cubic meters, with temperatures ranging between 400 and 900°C ...Alejandro Gil +11 more

Shallow geothermal energy for industrial applications: A case study
Sustainable Energy Technologies and Assessments, 2016Abstract Shallow geothermal energy is of great interest for HVAC (heating, ventilation and air conditioning) designers. While increasingly popular in the residential and commercial sectors, shallow applications are still little used in the industrial sector and unfamiliar to policy makers, designers and stakeholders [1].

De-Risking Shallow Geothermal Energy Storage in Challenging Urban Environments
24th European Meeting of Environmental and Engineering Geophysics, 2018In 2017 TNO and GFZ combined a dense accelerometer based high resolution surface seismic survey with a fibre optic based Vertical Seismic Profiling (DAS VSP) survey. The combined survey took place on a narrow patch of land in a challenging, noisy urban environment, in Berlin, Germany.
