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.

One of the major challenges regarding energy transition is to create active support towards renewable energy installations on a local level. The CROWDTHERMAL project presents practical approaches for involving local stakeholders in different measures in order to develop acceptable solutions. Based on technical evidence and data from concrete case studies, the project shows ways how community funding can increase social acceptance towards geothermal energy installations. The presented solutions are based on alternative financial schemes studies and risk mitigation analysis in geothermal projects.

Geothermal energy has emerged as an alternative heating source that can replace fossil energy. This mature technology is already in use all over Europe, but there are significant differences in its use between European countries. One possible explanation for this phenomenon concerns societal differences directly related to geothermal energy, the topic that is investigated in this study. The present work proposes using the societal embeddedness level (SEL) method to analyze and compare the status of non-technical factors affecting geothermal energy use in Hungary, Iceland, Norway, Poland, and Slovakia. The method considers four dimensions: environment, stakeholder involvement, policy and regulations, and markets and financial resources. Only Iceland fully covers the four dimensions by reaching all the milestones in the SEL framework. Iceland has the advantage of a long history of active use of geothermal energy for domestic use. The other countries face challenges within several of the dimensions, while the form and cause of these challenges are specific to each country. The findings illustrate that to mitigate climate change and drive the energy transition forward, both technical and societal factors related to various renewable energy sources must be assessed.

Due to advantageous conditions thermal wells have been operated in Hungary for over 140 years. With approximately 50 production wells in HódmezoA˝vásárhely and Szentes the largest operating geothermal fields are situated in the Southern part of the Great Hungarian Plain. Their total installed thermal power capacity exceeds 100 MW_th, however, less than 2% of the water produced is injected leading to a significant (cca. 35 m) sinkage of water levels. In this region, a complex geothermal reservoir investigation has been performed in order to provide solutions for sustainable reservoir management.
