Grue & Hornstrup - Geothermal Energy in Beius-Romania

Grue & Hornstrup – Geothermal Energy in Beius - Romania
The Geothermal Energy in Beius is an executed Joint Implementation (JI) project between Denmark and Romania. The project was supported by the Romanian company SC Transgex SA, the Danish Environmental Protection Agency, the Municipalities of Oradea and Beius, and the Danish project developer Grue & Hornstrup A/S.

In Beius-Romania, two geothermal wells supply heat to five substations in the City, which in turn are connected to apartment blocks and public buildings. Included in the project is the increase in well supply capacity, extensions of the primary pipe network, new connections to buildings, and new heat exchanger units in buildings.

New Geothermal District Heating Systems and Rehabilitation
The Geothermal Energy in Oradea and Beius project comprises the establishment of new district heating system components, along with the rehabilitation of existing district heating system components. The geothermal heat/water comes from existing, but underutilized, wells that were established as part of a decade’s long research program by the Romanian Ministry of Research. The capacity of these wells was significantly increased through the project’s new line-shaft pumps, and at the demand side, by new connections to and the rehabilitation of the existing district heating systems.

Emission Reduction
This JI project is reducing net CO2 emissions into the atmosphere through the use of geothermal energy which substitutes the combustion of natural gas, oil, and lignite. The geothermal energy is being used for both space heating and the heating of hot potable water. The project also reduces CO2 emissions related to the reduction of energy losses within the district heating systems.
 

In Beius, approximately 10,000 tons CO2e/yr will be reduced by replacing the use of 130,000 GJ/yr of natural gas and oil which is used in existing individual boiler units. The emission reductions take into account the substitution of electricity production, losses and efficiencies.
