An overview of the international classification and reporting systems for geothermal energy and the first attempts to bring Hungarian practice in line with these systems

Abstract

In the present paper an overview is provided of the most important international classification systems of geothermal energy. This involves a demonstration of the applicability of the UNFC-2009 classification framework to renewable energy resources, especially with respect to geothermal energy. Here an attempt is also made to classify some typical Hungarian geothermal projects which are in accord with the UNFC-2009 scheme, and then to illustrate this harmonization with a Monte-Carlo based resource estimation for the Hódmezővásárhely geothermal district heating project.
