Planned decommissioning of coal-fired plants in Europe requires innovative technical and economic strategies to support coal regions on their path towards a climate-resilient future. The repurposing open pit mines into hybrid pumped hydro power storage (HPHS) excess energy from the electric grid, renewable sources will contribute EU Green Deal, increase value, stabilize regional job market supply security. This study aims present preliminary phase geospatial workflow used evaluate land...
The development of three-dimensional geological models has proven to be critical for conceptualizing complex subsurface environments. This is crucial mining areas due their various hazards and unstable conditions. Furthermore, (3D) can the initial step numerical in order support decisions sustainable planning. paper illustrates results phases a 3D model within boundaries Kardia lignite deposit western Macedonia, Greece. It also highlights usefulness Geographic Information System (GIS)...
The main objective of the present study is investigation adsorption efficiency raw and heat-treated attapulgite clay for removing Pb Cu from aqueous solutions. removal each metal was studied separately with use one-substance effect certain factors, including solution pH ionic strength, contact time, adsorbent concentration, temperature treatment adsorbent, initial studied. In alkaline conditions, > 8.0, precipitation Pb(OH)2 Cu(OH)2 takes place, whereas at range 4.0–8.0 metals probably...
The main objective of the present study is to assess Cr(VI) concentrations in groundwater and surface water Loutraki Schinos areas. Totally, 38 samples were collected from both areas April May 2015. Both are bicarbonate-magnesium type (Mg-HCO3 -) very high Mg2+ (up 266mg/L) whereas vary among different groups (<1,6μg/L-120μg/L). Only 2 out 15 boreholes area have chromium above permissible level for drinking (50μg/L Cr(tot)) with maximum concentration being 74μg/L. In Schinos, three wells...
Energy supply security is currently a key priority for all European countries, and with global push towards decarbonized future, safe reliable energy storage becomes vital. The Union (EU) has introduced the Green Deal, an initiative objective of achieving carbon neutrality by 2050, effectively reducing greenhouse gas (GHG) emissions to zero. As Europe shifts away from fossil fuels, renewable sources like solar, wind, hydropower gain prominence. Hydropower, especially hybrid pumped (HPHS)...
The WINTER project, funded by the EU, aims to develop a web GIS interactive platform that will be used as tool for management of coal regions in transition. guide and engage stakeholders sharing best practices addressing transition challenges pilot at different stages. &#160;The applied methodology involved three-step process: 1) developing geodatabase import standardize geospatial datasets; 2) training implementing Machine Learning (ML) approach [1]; 3) identifying quantifying land...
W artykule zaprezentowana została interaktywna platforma internetowa służąca do efektywnego zarządzania transformacją w regionach węglowych okresie przejściowym opracowana ramach projektu WINTER, finansowanego ze środków Funduszu Badawczego Węgla i Stali. Została ona taki sposób aby mogła być z powodzeniem używana przez lokalne władze interesariuszy sektora węglowego, jak również zapewniający możliwość rozszerzenia na inne obszary stojące przed podobnymi wyzwaniami.
&lt;p&gt;Comprehensive risk assessments for subsurface utilisation projects such as in-situ coal conversion, deep geothermal energy, geological storage, and waste disposal are implemented to a limited extent in common practice. The impacts of processes on environmental hazards (e.g., migration groundwater-borne contaminants, induced seismicity, subsidence) often convoluted therefore not trivially predict. Furthermore, decisions project feasibilities commonly based expert knowledge...
Abstract. Quantifying impacts on the environment and human health is a critical requirement for geological subsurface utilisation projects. In practice, an easily accessible interface operators regulators needed so that risks can be monitored, managed, mitigated. The primary goal of this work was to create environmental hazards quantification toolkit as part risk assessment in-situ coal conversion at two European study areas: Kardia lignite mine in Greece Máza-Váralja hard deposit Hungary,...
&lt;p&gt;The definition of natural background concentration levels (NBLs) geogenic trace metals in groundwater is a challenging issue, particularly areas where anthropogenic activities are also present. The estimation NBLs, combination with environmental quality standards, such important for the establishment relevant threshold values. Over 100 samples were collected and analysed from four Cr(VI) impacted, alluvial bodies central Greece during two consecutive hydrologic years. A...
The CrITERIA project aims to deliver a harmonized data base, assist water resource management organizations and users on decision making when coping with scarcity, climate extreme events contaminated water. Contamination by Cr(VI) is used as an example of specific pressure problem that has be tackled. Comparative, collaborative research using real situation from case study areas in each the participating countries was base our methodology. Such had already been identified Greece Italy were...
The holistic approach of the Driver-Pressure-State-Impact-Response (DPSIR) analytical framework in combination with Geographical Information Systems was applied to selected Cr(VI) impacted groundwater bodies. For characterization “state”, 157 samples including field blanks were collected during wet and dry seasons 2017 2018 several physicochemical parameters determined. In Loutraki, ranged from 12 62 μg/L while NO3 Cl maximum values 157mg/L 218mg/L respectively. Very high concentrations (up...
