“…The researchers stated that the use of the OWA method provided a model for generating prospective geothermal maps with different optimistic and pessimistic strategies. Tinti et al [41] used a GIS framework and the AHP method to assess the suitability of shallow geothermal technologies. This study, which involved comparing a large number of shallow geothermal source-related criteria and factors, reported that it was possible that one can draw a suitability map of technologies for Europe using the AHP method.…”

In recent decades, many countries have shown a growing interest in the use of renewable energies for power generation. Geothermal energy is a clean and environmentally friendly source of renewable energy that can be used to produce electricity and heat for industrial and domestic applications. While Afghanistan has undeniably good geothermal potential that can be utilised to alleviate the country’s current energy limitations, so far this potential has remained completely untapped. In this study, the suitability of 21 provinces for geothermal project implementation in Afghanistan was evaluated using multiple multi-criteria decision-making (MCDM) methods. The stepwise weight assessment ratio analysis (SWARA) method was used to weigh each criterion while the additive ratio assessment (ARAS) method was used to rank potential geothermal sites. The technique for order of preference by similarity to ideal solution (TOPSIS), the vlse kriterijumsk optimizacija kompromisno resenje (VIKOR), and the weighted aggregated sum product assessment (WASPAS) methods were also used in this study. These rankings were then examined via sensitivity analysis which indicated that a 5% change in criteria weights altered the rankings in all methods except the VIKOR method. Volcanic dome density was ranked the most important criteria. All the methods identified Ghazni province as the most suitable location for geothermal project implementation in Afghanistan.

“…Data on the geology of the area, ambient temperature and amplitude, geothermal heat fl ow, thermal conductivity of sediments and bedrock, thermal diffusivity of sediments and bedrock and thickness of sediments were known for the four selected points with a precision of 1 km ×1 km grid (Tinti et al, 2018). The ground temperature profi les were calculated using Equation 1, without taking into consideration any SUHI effect.…”

The replacement of natural soil and vegetation by artifi cial surfaces increases temperatures of the surrounding air and subsurface throughout the year, because of indirect solar heating of urban structures, building heat losses and land use change. This phenomenon is called Urban Heat Island and it can be better perceived during the nighttime, when the city releases the heat accumulated during the day. During the daytime, due to relatively small amounts of solar radiation received by the urban surface, especially in high-density cities in arid and semi-arid climates, the Urban Cool Island can be identifi ed as well. The present work illustrates a mixed probabilistic-deterministic method to estimate ground temperature at shallow depths, starting from information on geology, hydrogeology, climate, but also urban presence, through correlations with global land cover and population density. A dedicated mapping on a regular grid has been produced. Results have been compared with ground and aquifer temperature available in literature, for some representative cities of the Italian Peninsula and the Alpine Zone. Preliminary validations are encouraging and can be taken as a starting point for more comprehensive mapping of ground temperature evolution at a regional scale.

“…Computational procedures [22] and numerical models and simulations have been developed by different authors [23e27] to allow simulation and design of systems. But to allow an overall assessment, the question about the site-specific potential of the technology is critical, where climatic, building type and underground site-specific information become key when it comes to assessing SGE potential [25,28,29]. Regarding policy decisions, additional local variables must be taken into account, such as environmental benefits or closeness to the resource to be exploited, among others.…”

“…Yet, so far, methodologies assessing spatial SGE suitability or/ and SGE potential developed in Europe cover a broad variety of scales, from small areas (plots to cities) [23,26,35] to larger ones (from regions to countries) [24,36]. Very little literature covers continental areas [29,37] whilst most studies are focused on a regional scale.…”

Spatial analysis of indicators affecting the exploitation of shallow geothermal energy at European scale

Shallow Geothermal Energy (SGE) exploited by vertical close loop Ground Source Heat Pumps (GSHP) is a proven, reliable, and widespread renewable heating and cooling technology. However, in many regions there is still a lack of awareness among policy makers and end users, constituting a major constraint to wider deployment of SGE. In order to contribute to its market consolidation, this work focuses on bringing to light relevant spatial information affecting the suitability of SGE exploitation. This information is the result of the systematization of geological, climatic, and environmental open and available data translated into performance indicators. A set of thematic maps was created using Geographic Information Systems (GIS) comprising the European Member States and other European countries. The relative area and the amount of population affected per indicator was spatially analyzed to determine the most common values found and the affected population. The relationship between area percentage and population affected percentage per indicator was also analyzed and allowed to identify the most common indicators values in areas where high energy demands are expected. Additionally, an example of how this data can be used into a Multi-Criteria Decision-Making (MCDM) framework is shown.
