    Abstract

    Globally, low enthalpy (i.e. low temperature, <100°C) geothermal resources are widespread and could offer a valuable long-term source of low carbon industrial or domestic heat. The question is, how low carbon is low enthalpy geothermal heat? We analysed the carbon emissions from low enthalpy deep geothermal heat using the Hill of Banchory feasibility project as a case study. The project constraints represent many typical low enthalpy heat prospects, and the methodology we develop can be readily adapted to suit individual projects.
