Economic Evaluation of Eight Regional Scenarios for the Deployment of Carbon Capture, Use and Storage in Southern and Eastern Europe to 2050

During the three-year EU-funded STRATEGY CCUS project [1] [3] (2019-2022), Carbon Capture, Use and Storage (CCUS) scenarios formulated for eight regions in Southern and Eastern Europe were developed and economically evaluated up to 2050. These regional CCUS scenarios are based on both the performances of local industries in operation and for which CCUS is a relevant mitigation alternative, as well as the regional storage capacities known to date. The eight CCUS regional scenarios are in: 1) Paris basin and 2) Rhône Valley in France, 3) Ebro basin in Spain, 4) Lusitanian basin in Portugal, 5) Northern Croatia, 6) Upper Silesia in Poland, 7) West Macedonian area in Greece and 8) Galati area in Romania. They cover an extensive and original portfolio of possible CCUS business models. While some scenarios assume that the captured CO2 is used for synthetic methane or chemical production, in most cases the captured CO2 is sent to CO2 storage facilities. The biogenic CO2 captured is monitored and its storage time in new uses watched. The economic evaluation considers the negative CO2 emissions resulting from the long-term storage or use of captured biogenic CO2. This paper compares the economic Key Performance Indicators (KPIs) of these eight CCUS business cases with the carbon penalties that would have been charged to the same industries to remain in compliance with the European Union - Emissions Trading System (EU ETS). The calculated KPIs mainly reflect the costs and revenues expressed in euros per ton of CO2 avoided or removed for the whole regional scenario until 2050

BIOSORPTION EVALUATION OF SYNTHETICDYE FROM FOOD INDUSTRY WASTEWATER ONTO SILKWORMCOCOONS: PRELIMINARY STUDIES

The aim of this study was to evaluate thesynthetic azo dye (tartrazine) biosorption onto second line silkworm cocoons. Batch adsorption system was used to investigate the effect of pH and initial tartrazine concentration in theliquid phase. Also, the kinetic mechanismwas investigated at 20°C and pH 2.0.The highest adsorption was obtained at the lowest pH evaluated, while the assays with pH above 3.0 did not show significant adsorption at the first hour of theprocess, indicating that biosorption is more favorable at lower values ofpH.The adsorption kinetic was studied at pH 2.0andcompared withthe kinetic mechanism ofconvective mass transfer and diffusion models.The kinetic behavior of biosorption process showed a high amount of dye adsorbedat the beginning of the process, however, after saturation of the functional groups, the adsorption rate decreased over time until saturation. After 24 hours of batch operation, the uptake of tartrazine onto silkworm cocoons was 40.39 mg g-1,and the rate of adsorption reduces from 3.430 to 0.003 mg min-1g-1, suggesting that the process approaches the equilibrium. The Crank model provided the best fit. The results revealed that silkworm cocoons have the potential to be used as a biosorbent for wastewater treatment containing tartrazin

An active tectonic field for CO2 storage management: the Hontomín onshore case study (Spain)

One of the concerns of underground CO2 onshore storage is the triggering of induced seismicity and fault reactivation by the pore pressure increasing. Hence, a comprehensive analysis of the tectonic parameters involved in the storage rock formation is mandatory for safety management operations. Unquestionably, active faults and seal faults depicting the storage bulk are relevant parameters to be considered. However, there is a lack of analysis of the active tectonic strain field affecting these faults during the CO2 storage monitoring. The advantage of reconstructing the tectonic field is the possibility to determine the strain trajectories and describing the fault patterns affecting the reservoir rock. In this work, we adapt a methodology of systematic geostructural analysis to underground CO2 storage, based on the calculation of the strain field from kinematics indicators on the fault planes (ey and ex for the maximum and minimum horizontal shortening, respectively). This methodology is based on a statistical analysis of individual strain tensor solutions obtained from fresh outcrops from the Triassic to the Miocene. Consequently, we have collected 447 fault data in 32 field stations located within a 20 km radius. The understanding of the fault sets’ role for underground fluid circulation can also be established, helping further analysis of CO2 leakage and seepage. We have applied this methodology to Hontomín onshore CO2 storage facilities (central Spain). The geology of the area and the number of high-quality outcrops made this site a good candidate for studying the strain field from kinematics fault analysis. The results indicate a strike-slip tectonic regime with maximum horizontal shortening with a 160 and 50◦ E trend for the local regime, which activates NE–SW strike-slip faults. A regional extensional tectonic field was also recognized with a N–S trend, which activates N–S extensional faults, and NNE–SSW and NNW– SSE strike-slip faults, measured in the Cretaceous limestone on top of the Hontomín facilities. Monitoring these faults within the reservoir is suggested in addition to the possibility of obtaining a focal mechanism solutions for microearthquakes (M < 3)This work has been partially supported by the European Project ENOS: ENabling Onshore CO2 Storage in Europe, H2020 Project ID: 653718 and the Spanish project 3GEO, CGL2017-83931-C3-2-P, MICIU-FEDE

El almacenamiento geológico de CO2 como solución viable para un futuro sostenible y su aplicación en la cuenca del Ebro

STRATEGY CCUS es un proyecto de tres años financiado por la Unión Europea dentro del programa Horizonte 2020 para apoyar el desarrollo de energía e industria bajas en carbono en el sur y este de Europa. Se centra en ocho regiones europeas seleccionadas por su nivel de emisiones de CO2 y potencial para la captura, utilización y el almacenamiento geológico. El proyecto tiene como objetivo alentar y apoyar iniciativas en estas regiones mediante la elaboración de un plan de desarrollo local y modelos de negocio adaptados a las necesidades de la industria. Estas ocho regiones, en conjunto, representan un 45% de las emisiones producidas por la generación de energía e industria europea durante 2016

A techno-economic Analysis Tool for Regional CO2 Capture, Transport, Use and Storage Scenarios

Carbon capture from industrial, high concentration CO2 sources, combined with CO2 transport, utilization and storage (CCUS) is a way to reduce greenhouse gas emissions. CCUS will play an important role in our transition into, and, also beyond the green shift, as CCUS both significantly reduces emissions from industrial processes and offsets emissions from hard-to-remove sectors – leading to the global net-zero society. We study here how the deployment of CCUS networks and commonly shared infrastructure could be evaluated using a dedicated techno-economic analysis tool presented here. A scenario-approach was taken in the development of CCUS network to decarbonize industrialized regions. In this context, a scenario is defined as a planned deployment of capture, transport, utilization and storage units – each at a given location and at given time between now and 2050. The Excel-based tool presented in this paper, allows for both the design and technical-economic analysis at regional scale. It allowed to define scenarios in a time-dependent spatial network connecting capture points to CO2utilization factories and storage locations via transport by pipelines, or via trains, trucks, or vessels/barges. To set up different scenarios, and to ensure both their internal consistency and comparability with each other, a dedicated tool was developed in the STRATEGY CCUS project funded though EU Horizon 2020 program (grant agreement No 837754). The tool use common input variables shared between different modules of the tool and scenarios which enables comparison between decarbonization of different regions. The tool aims to provide more realistic, and comparable estimates for future energy and material use, emissions avoided and negative emissions, revenues created by downstream industries, broken down in discounted and un-discounted costs per ton of CO2 avoided. The tool allows for future cost reductions due to technology maturation, economy of scale and learning, as well as inflation and energy price outlooks. This paper describes in more detail the structure of the tool, how it was used, and the lessons learned from its development. Basically, the tool underwent two development stages: The first when the internal logic was developed and the tool itself was put together, and secondly, when eight regional European teams used the tool, its quality and internal consistency significantly improved. Feedback and constructive criticism by users were paramount in the development of the tool

Developing a new innovative methodology to integrate geophysical techniques into characterization of potential CO2 storage sites: Lopín structure (Southern Ebro basin, Spain)

Abstract:One of the main challenges facing geological storage is to identify cost-effective methodologicalworkflows for characterizing and monitoring geological storage sites. In the framework of the ALGECO2 pro-ject, led by the IGME (Geological and Mining Institute, Spain), a preliminary study of the Lopín site in the NEof Spain indicated conditions were promising for geological storage of CO2. However, the poor quality of thelegacy seismic reflection data precluded thorough characterization. Within the H2020 PilotSTRATEGY pro-ject, one of the possible selected target reservoirs was the Lopín structure. In order to characterize its geometryand physical properties as required to properly evaluate its storage potential, IGME applied a new emergingmethodology that integrates reinterpreted reflection seismic data with newly acquired and interpreted gravity,passive seismic and petrophysical data. This methodology was successfully applied along one seismic profile. Inthis paper, we present the results of this integration as thefirst step towards characterizing the site and evaluatingits suitability for storage.Funding for this research came from the Horizon 2020 Framework Programme (European Climate,Infrastructure and Environment Executive Agency (CINEA), award 101022664

pilotSTRATEGY project 2021-2026: “CO2 Geological Pilots in Strategic Territories”

[EN] The pilotSTRATEGY (2021-2026) is investigating geological CO2 storage sites in industrial regions to support development of large-scale carbon capture and storage (CCS). It is focused on deep saline aquifers–porous rock formations filled with brine several kilometres below ground – which promise a large capacity for storing captured CO2. The goal of the characterisation is to assess the site’s containment, injectivity, capacity, integrity, hydrodynamics, and monitorability in order to ensure safe and permanent storage of CO2. PilotSTRATEGY covers the initial stages of project development up to the pre-final investment decision (pre-FID), regulatory approval and permitting of storage, and applied on selected structures of Paris Basin in France, the Lusitanian Basin in Portugal and the Ebro Basin in Spain, and in lower detail, in West Macedonia in Greece and Upper Silesia in Poland.The project has received funding from the European Union’s Horizon 2020 programme (10.1 million Euros, No. 101022664).Peer reviewe

Diseño de una metodología para el estudio y recuperación de suelos urbanos degradados: aplicación en Asturias

Se entiende por suelos urbanos degradados aquellos terrenos que, actualmente ubicados en áreas urbanas o periurbanas, se ha originado como consecuencia del abandono o semiabandono de antiguas zonas industriales, comerciales, mineras, u otras actividades tal que, dada su naturaleza, han podido generar contaminación en el suelo y/o subsuelo. Este tipo de terrenos, independientemente del área geográfica donde se ubiquen, presentan fundamentalmente dos características comunes: suponen un riesgo para la salud de las poblaciones o ecosistemas próximos, y su presencia está asociada a un degradado tejido social y económico de las áreas donde se enclavan. A pesar de que son terrenos disponibles y que pueden ser reutilizados, las necesidades de suelo de las áreas urbanas están siendo cubiertas a costa de suelos vírgenes de buena calidad, situación esencialmente inconsistente con el principio de uso sostenible de los recursos naturales. En buena medida las razones de este fenómeno son de naturaleza económica por cuanto no siempre existen incentivos suficientes para fomentar iniciativas, públicas o privadas, que opten por la reutilización de terrenos abandonados. Sin embargo, como se pretende demostrar con este trabajo, es posible y deseable potenciar este tipo de iniciativas, públicas o privadas, que opten por la reutilización de terrenos abandonados. Sin embargo, como se pretende demostrar con este trabajo, es posible y deseable potenciar este tipo de iniciativas, para lo cual deben integrarse y combinarse adecuadamente los tres pilares del desarrollo sostenible: economía, sociedad y medio ambiente
