Production of Electricity from Geothermal




Climate change adaptation:

Technical Screening Criteria:
Depending on the primary objective of the activity, refer to:  Screening criteria for adapted activities  Screening criteria for an activity enabling adaptation Users of the Taxonomy should identify and explain which criteria they are responding to.

Climate change adaptation do not significant harm:

Summary:
The main potential significant harm to other environmental objectives from Production of electric energy from high-enthalpy geothermal system is associated with: • Non-condensable geothermal gases with specific environmental threats, such as H2S, CO2, and CH4, are often released from flash-steam and dry-steam power plants. Binary plants ideally represent closed systems and no steam is emitted. • Possible emissions to surface and underground water

Mitigation:
If the activity operates at above the threshold for substantial contribution to climate change mitigation, there should be: • no increase in emissions intensity of the activity as a result of the adaptation; and • no activity can have emissions intensity above the average emissions intensity of all electricity generation facilities in the respective region. The TEG interprets DNSH to mitigation as avoidance of activities which would compromise the EU's net zero by 2050 climate mitigation targets. We have determined that activities which operate below the 100g threshold provide a significant contribution, and that activities that operate above the regional average of 262g (as per the IEA) would cause significant harm. Therefore, while activities below this this 262 threshold are not considered to be providing a substantial contribution, they are also not considered to be doing significant harm.

Relevant regulation:

Water:
• Identify and manage risks related to water quality and/or water consumption at the appropriate level. Ensure that water use/conservation management plans, developed in consultation with relevant stakeholders, have been developed and implemented. • In the EU, fulfil the requirements of EU water legislation.

Regulation:

Pollution:
Discharges to water bodies should comply with individual license conditions for specific operations, where applicable, and/or national threshold values in line with the EU regulatory framework (i.e. EU Water Framework Directive1 and Daughter Directives). Emissions to air: the operations of high-enthalpy geothermal energy systems should ensure that adequate abatement systems are in place to comply with existing EU Air Quality Legislation and BAT ; including but not limited to <1 μg/Nm3 Hg. Thermal anomalies associated with the discharge of waste heat should not exceed 3°K for groundwater environments or 1.5°K for surface water environments, respectively.

Ecosystems:
Ensure an Environmental Impact Assessment (EIA) has been completed in accordance with the EU Directives on Environmental Impact Assessment (2014/52/EU) and Strategic Environmental Assessment (2001/42/EC) or in the case of activities located in non-EU countries other equivalent national provisions or international standards for activities in non-EU countries (e.g. IFC Performance Standard 1: Assessment and Management of Environmental and Social Risks) – including ancillary services, e.g. transport infrastructure and operations). Ensure any required mitigation measures for protecting biodiversity/eco-systems have been implemented. For sites/operations located in or near to biodiversity-sensitive areas (including the Natura 2000 network of protected areas, UNESCO World Heritage sites and Key Biodiversity Areas (KBAs), as well as other protected areas), ensure that an appropriate assessment has been conducted in compliance with the provisions of the EU Biodiversity Strategy (COM (2011) 244), the Birds (2009/147/EC) and Habitats (92/43/EEC) Directives or in the case of activities located in non-EU countries, other equivalent national provisions or international standards (e.g. IFC Performance Standard 6: Biodiversity Conservation and Sustainable Management of Living Natural Resources) – based on the conservation objectives of the protected area. For such sites/operations, ensure that: • a site-level biodiversity management plan exists and is implemented in alignment with the IFC Performance Standard 6: Biodiversity Conservation and Sustainable Management of Living Natural Resources; • all necessary mitigation measures are in place to reduce the impacts on species and habitats; and • a robust, appropriately designed and long-term biodiversity monitoring and evaluation programme exists and is implemented.
