Harvested from ORCID Public Data FileGuttorm Alendal in OpenAIREAbstractThis paper assesses how parameter uncertainties in the model for rise velocity of CO2 droplets in the ocean cause uncertainties in their rise and dissolution in marine waters. The parameter uncertainties in the rise velocity for both hydrate coated and hydrate free droplets are estimated from experiment data. Thereafter the rise velocity is coupled with a mass transfer model to simulate the fate of dissolution of a single droplet.The assessment shows that parameter uncertainties are highest for large droplets. However, it is also shown that in some circumstances varying the temperature gives significant change in rise distance of droplets.

Harvested from ORCID Public Data FileWagner, F. in OpenAIREAt the Ketzin pilot site, Germany, electrical resistivity tomography (ERT) is a substantial component in a multi-disciplinary monitoring concept established in order to image CO2 injected in a saline aquifer. Since more than five years, crosshole ERT data sets have repeatedly been collected using a borehole electrode array acting as a permanent reservoir monitoring tool. This contribution summarizes the aspects being essential for a successful deployment and operation of such a downhole installation. It is shown that the presented installation can facilitate stable and reliable data collection at least throughout the investigated five- year period of ongoing CO2 injection. Based on the experiences being gained so far, it is concluded that a properly calibrated and integrated downhole ERT system allows for mapping of quantitative CO2 saturation estimates in the subsurface. 12th International Conference on Greenhouse Gas Control Technologies, GHGT-12 Energy Procedia, 63 ISSN:1876-6102

Harvested from ORCID Public Data FileCarsten Leven in OpenAIREAbstractAn integrative hierarchical monitoring approach is proposed, with the aim of reliably detecting and assessing possible leakages from storage formations into the shallow subsurface. This hierarchical approach - with method developments and applications ranging from remote sensing (infrared spectroscopy, micrometeorology-based flux measurement), to regional measurements (geophysics and chamber based soil CO2 flux measurement), to local in-situ measurements (Direct Push Technology) - will allow large spatial areas to be consistently covered. The paper introduces a hierarchical monitoring approach applied in the MONACO project and reveals first results from measurements taken at natural analogue sites in the Czech Republic. These results indicate that the hierarchical monitoring approach represents a multidisciplinary modular concept working in different scales and resolutions.

Harvested from ORCID Public Data FileKempka, T. in OpenAIREAbstractSubsurface storage of fluids triggers pressure and volume changes in reservoirs, caprocks and faults. In this context, hydraulic fault conductivity can increase by several orders of magnitude, promoting upward migration of reservoir fluids into shallow freshwater aquifers. In the present study, we compared one-way and two-way hydromechanical couplings to quantify the impacts of subsurface fluid storage on fluid migration via a fault. Our simulation results emphasize the requirement of two-way coupled hydromechanical simulations, since neglecting petrophysical changes in the one-way coupling leads to an underestimation of fault pressure gradients, and thus fluid migration.

Harvested from ORCID Public Data FileAshok Singh in OpenAIREAbstractIn this paper, conceptual modeling and numerical simulation of two-phase flow during CO2 injection into deep saline aquifers is presented. The work focuses on isothermal transport and deformation processes in the vicinity of the injection well including hydromechanical failure analysis. Governing differential equations are based on balance laws for mass and momentum completed by constitutive relations for the fluid and solid phases as well as their interactions. Constraint conditions for the partial saturations and the pressure fractions of CO2 and brine are defined. To characterize the stress state in the solid matrix the effective stress principle is applied. The coupled problem is solved using an in-house scientific finite element code, and verified with benchmarks.In terms of application-oriented aspects, we examine the mechanical integrity of a deep saline aquifer during the injection of supercritical CO2. The analysis is conducted with a numerical scheme of the capillary pressure and non-wetting phase pressure for the two-phase flow process. In this study, unidirectional hydromechanical coupling is considered. Caprock stability is monitored in time, referenced to the potential for hydraulic fracture and shear slip along an optimally oriented shear plane for a suite of injection pressures. For reasonable parameter values and the chosen aquifer geometry, significant mechanical failure (and potential breach of integrity) is expected in the shale caprock for all but low injection rates. This indicates that the analysis of the hydromechanical response is crucial for proper selection of injection sites, injection rates, and total storage capacity.

More specifically for this paper, the project sets out to reveal the impacts of relevant impurities in the CO2 stream on the design, operation and costs of the capture, transport and storage infrastructure and to provide recommendations for optimized CO2 quality through techno-economic assessments (amongst other considerations). This paper gives an overview of the work being carried out to investigate the impact of CO2 quality in various areas including corrosion, water content in the CO2 stream and the injection and storage processes. The paper reports on the derived impacts of the above mentioned aspects of CO2 quality. These impacts are combined with estimates of the cost of measures to mitigate or prevent these impacts from affecting the operation of the CCS system, or of adapting of CCS system design. Thus, the impacts can be set out as a set of cost functions relating to Capex and Opex and including the effects of overall availability and process efficiency changes. A specifically designed CCS chain model is used to assess the impacts on a number of reference CCS chains, carrying out comparative economic trade-offs to both understand the fullchain whole-life economics of certain CO2 impurities at different levels and then to potentially optimize a purity specification for various sets of circumstances.

Harvested from ORCID Public Data FileMichael Schäfer in OpenAIREAbstractIn future, an additional potential of control reserve as well as storage capacities will be necessary to compensate fluctuating energy generators such as wind and solar power plants. The core objective of the joint research project “arrivee” is the integration of widely available wastewater treatment plants (WWTP) with anaerobic sludge digestion into an optimized control reserve and storage concept. Therefore the excellent technical conditions of those plants such as combined heat and power (CHP) units as well as gas storage units will be used. By means of analyzing energy consumption and production processes of existing WWTPs the potential to provide ancillary services for energy grids is investigated. Using a mathematical model of an existing WWTPs the effects of external interventions for the supply of ancillary services under different conditions are tested. Therefore, different processes will be analyzed in detail. The integration of WWTPs into a virtual power plant (VPP) is mandatory because a single plant can’t provide enough capacity to participate on energy markets. The initial results present a theoretical potential of control reserve of WWTPs in Germany focusing on a CHP/gas unit of a magnitude of 300 MWel. This results show a substantial potential of WWTPs to provide ancillary services, by reshaping the existing infrastructure in a sustainable, ecological and economic way. This may contribute significantly to a stable operation of energy grids and to further integration of renewable energy sources in the frame of energy system transition.

Harvested from ORCID Public Data FileYoshiyuki Yokoo in OpenAIREAbstractRadioisotope concentrations (Cs-137 and I-131) in sewage sludge, obtained on a daily basis in the Fukushima city wastewater treatment plant from end of April 2011 until end of December 2013, have been analysed for their evolution with time, and the time series have been compared to similar data from central Europe after the Chernobyl accident. Additionally, daily rainfall data have been considered for Fukushima.The long-term trends for Cs-137 are very similar between Japan and Europe, indicating a decrease of concentration with an initial half-life of about 1 year with a tendency towards a slower decrease at later times. Short-term Cs-137 data indicate a dominating influence of rainfall – each significant rainfall event leads to a sharp increase of sludge Cs-137 concentration. Absolute values (maximum: ca. 6000 Bq kg-1) are relatively low compared to Europe after 1986 – this is attributed to the different types of sewer systems: separated in Fukushima, collecting only small amounts of rainfall with the wastewater, mixed in many cities in Europe, collecting rainwater and wastewater in the same sewer. I-131 was detectable during short intervals and at relatively constant maximum concentration (ca. 1000 Bq kg-1) during the whole observation period. The origin is suspected to be routine medical application of the isotope, which has been shown to contribute significantly to sewage sludge concentration wherever it is in use.

Additionally, daily rainfall data have been considered for Fukushima.The long-term trends for Cs-137 are very similar between Japan and Europe, indicating a decrease of concentration with an initial half-life of about 1 year with a tendency towards a slower decrease at later times.

The management of marine waste in Latvia is not well developed. Brown algae Fucus vesiculosus is one of the most abundant seaweeds in Latvia. The chemical composition of brown algae Fucus vesiculosus, collected from the Gulf of Riga, was evaluated. Algae contain higher amounts of both macroelements (490 – 21500ppm; P, K, Ca, Mg, Na, Fe, Mn) and trace elements (0.11 – 930ppm; Zn, Cu, Cr, Pb, Sr, As, Cd, Se) than terrestrial plants. The obtained composition was used to describe the potential uses of seaweed. Food, pharmacy and bioenergy were considered as potentially the best sectors for macroalgae use. Due to high levels of heavy metals in seaweed, it is not recommended to use F. vesiculosus from Gulf of Riga as a food. The best potential use is found to be using it as biomass feed to obtain biogas.
