“…In the recent years, different RES (Renewable Energy Sources), currently adopted in residential buildings, were firstly investigated and then applied to the agricultural and industrial production context [11][12][13][14][15], greenhouses included [16][17][18][19]. To date, one of the most promising RES for farm facilities is represented by shallow geothermal energy [20] already widely used for residential conditioning [21].…”

“…The use of BHEs for long-term thermal energy storage (from solar, waste heat, and other sources) is called BTES (borehole thermal energy storage). The depth of BHEs can vary from a few meters to even 200 m and beyond, depending on the energy needs, the available space, and the ground conditions [8]. In fact, shallow geothermal exploitation is strongly affected by the thermal and hydraulic properties of the ground layers and by the presence of aquifers [9].…”

Borehole thermal energy storage systems represent a potential solution to increase the energy efficiency of renewable energy plants, but they generally have to comply with strict regulatory frameworks, mainly due to the deliberate modification of the subsoil’s natural state. This paper presents the design, testing, and monitoring phases carried out to set up a borehole thermal energy storage (BTES) system able to exploit the excess solar heat from photovoltaic thermal (PVT) collectors. The case study is the refurbishment of a pig nursery barn, hosting up to 2500 weaners, in Northern Italy. This study aims to define a BTES suitable to develop a heating system based on renewable energy, ensuring environmental protection and long-term sustainability. The retrofitting intervention includes the installation of a dual-source heat pump (DSHP), in order to recover the solar heat stored in summer during winter. Specific constraints by the Environmental Authority were as follows: maximum storage temperature of 35 °C, authorization to intercept the shallowest aquifer at a maximum depth of 30 m, obligation of BHE grouting, and the definition of a strategy for continuous measuring and monitoring of the groundwater’s thermophysical properties. The results were used as inputs to optimize the design and installation of the integrated system with PVT, BTES, and DSHP.

“…This natural clean indigenous resource is available all around the globe, and its concentration is highly dependent on the general geological context (greater concentrations in hydrothermal systems in volcanic regions, at plate boundaries, lower concentrations in thermal gradient in shallow levels). Geothermal resources can, thus, be harnessed either for electricity production or directly used for heating, cooling, and hot water [1,2].…”

Geothermal energy is a resource that has the potential for development in many countries around the world. Despite its versatility and economic viability, this resource faces numerous obstacles that hinder its deployment and capacity for achieving a similar market share as other renewable and clean energy sources. Both technical and non-technical barriers can be highly detrimental to the implementation of geothermal projects. A social license to operate (SLO) is a tool that can help the deployment of geothermal energy. As a new concept, SLO is little developed in the business literature but is still being adopted in many industries. Its main challenges reside in its context-dependence and the lack of clear frameworks to utilize it. This paper introduces, in a first known attempt, through a qualitative approach, a conceptual model of the social license to operate in the geothermal energy sector. For its development, three case studies, working group discussion and surveying were conducted in the framework of the H2020 funded CROWDTHERMAL project, which aims to empower EU citizens for direct participation in geothermal projects through crowdfunding. Findings of this paper also drew on existing general conceptual models of the SLO, and experiences from other sectors that have developed their own SLO models. The paper contributes to a more contextualized understanding of the social license within the geothermal sector and sheds the light on practices and challenges that influence the acquisition and maintenance of SLO in geothermal energy projects and initiatives.
