TWI principal project leader, Briony Holmes is set to present findings from the collaborative GeoSmart project at EUROCORR 2022, in Berlin. In this event, Briony will be presenting on ‘Materials Compatibility Study for Geothermal Plant’ during the ‘Corrosion in Green and Low Carbon Energy Technologies’ session. The presentation will deliver details of the testing of a series of materials that are likely to be used in geothermal assets.
Geothermal fluids are an established means of producing energy, with plant efficiencies based on the fluid temperature as well as the reinjection temperature. If heat could be extracted from the geothermal fluids down to lower reinjection temperatures, it would be possible to improve plant efficiency. However, these lower temperatures could also lead to more scaling in components.
To gain these improved efficiencies, modifications to a high enthalpy power plant, with the inclusion of an additional heat exchanger and a retention tank that would allow for the removal of silica from the fluid before reinjection were envisaged.
