The second phase of geothermal investigations in Ireland 1986-1989
This report summarises the results of the work on geothermal energy carried out in Ireland during the third EC Geothermal R&D programme. The investigation of low enthalpy geothermal resources involved regional geological mapping, temperature measurement of springs, geophysical surveys, a study of the hydrochemistry of new springs and both deep (500 m) and shallow drilling. As Ireland is located in a stable tectonic environment, only low enthalpy geothermal energy can be expected to occur, located where deep groundwater circulation is able to take place. Indirect evidence suggests water, at least up to 30 C, does exist. However, the three 500 m deep boreholes drilled during the project failed to find water significantly warmer than the adjacent springs (14 C to 23 C).
