One of the goals within the ENGINE project was, as part of the WorkPackage2 (WP2), to locate and classify main Geothermal Lighthouse projects, related to ENGINE topics and significant on a European scale. At first, only projects using geothermal for power/energy production are included; excluding projects using heat pumps.
The intention is to give an overall broad presentation of the most important Lighthouse Projects mainly based on a questionnaire guided by a simplified structure and relevant keywords and on additional information derived from the Internet and the World Geothermal Proceedings (WGC2000 and WGC2005).
The hope was that the questionnaires could lead to a condense description of each project suitable for the public and for displaying on the ENGINE Web-site, - even though some questions could be difficult to answer (project could be in it’s early phase; rules of confidentiality etc..).
Based on a list of the known most important projects possible contact persons, either in charge or persons that could have knowledge of the project, received a questionnaire that was divided into two parts:
1) Comparable facts/statements that, for each project, could pop-up when e.g. the mouse pans over the site-location map on the Web-site; e.g. Web-site link, no. of wells, avg. flow rate, capacity etc.
2) Information to follow the pop-up facts, i.e. a short additional text displayed as information boxes divided into 4 categories; exploitation history, reservoir characteristics, exploitation, and future plans. If possible, a few relevant figures were appreciated.
Out of 17 questionnaires 11 were returned and have resulted in an updated list of contact persons and information on projects covering 4 main types; 1) EGS or related EGS projects, 2) Hydrothermal projects, 3) Technological projects and 4) Other Projects.
Furthermore, the returned questionnaires also served as a good basis for compiling a Web-site suitable for the public displaying. Examples of this will we shown.
Other geothermal projects e.g. in Poland, Denmark, Slovakia and Greece are mainly dedicated for heating purposed and was at first not relevant for the ENGINE project. In the future, it could be informative to incorporate theses projects. Furthermore, projects that have no production or drill sites, but where tools, software or methodologies are implemented for improving the use of geothermal energy could also be appreciated.
