    CRM-geothermal - Gas chemical measurements at the Tuzla, Seferihisar and Dikili geothermal fields, Turkey (2024)
    GFZ Data Services
    Details
    Publication Date: 2024-05-27
    Description: To enhance the EU's economic autonomy, feasible options for local sourcing of critical raw materials that would allow for shorter supply routes along with ethical and responsible value chains are under contemplation. Social acceptance of mining in Europe is, however, low, and the establishment of new mining sites faces strong public opposition. Therefore, innovative solutions for the production of primary raw materials need to be developed. A new idea for raw material extraction is the extraction of essential elements from geothermal fluids. Deep geothermal fluids, increasingly used for energy production, often contain high concen-trations of dissolved ions and gases in commercially interesting concentrations. The EU-funded project CRM-geothermal aims to develop new technologies to extract these highly relevant elements, including helium, during geothermal production cycles. In this way, an environmentally friendly and socially acceptable exploration and exploitation method could be deployed. One aim of the CRM-geothermal project is to gain an overview of the actual quantities of critical raw materials in various geothermal fluids in Europe by taking and analyzing fluid samples. In Turkey for instance, classical high enthalpy (volcanic) systems exist, which are representative for many geothermal areas worldwide. The sites are located at the edges of tectonic plates and close to areas undergoing volcanic activity. The brines are mixed with seawater and circulate in the deeper crust. The data publication contains analyses results of three gas samples from Tuzla, two samples from Seferihisar geothermal power plant and one sample from the Dikili geothermal field in Turkey, taken in 2023 as part of the CRM-geothermal project.

    Publication Date: 2024-05-22
    Description: The EU funded project CRM-geothermal aims to establish an overview of the potential for critical raw materials (CRM) in geothermal fluids across the EU and third countries (Ref). Within this framework, the geothermal sites of Tuzla, Seferihisar and Dikili in eastern Turkey have been visited in March 2023. To estimate the potential of CRM at these sites, a comprehensive sampling program was performed. Rock samples (drill gravel) of the production borehole and scaling from gas-water separators were obtained. Furthermore, sampling of geothermal fluids (gas and brine) and precipitates (salt) along the production line was performed. Here, the results of the geochemical analyses of solid sample materials (drill gravel, scales and salt) are presented. All analyses were performed in the ElMiE-Lab (Elements and Minerals of the Earth Laboratory) at German Research Centre for Geosciences Potsdam, Germany (https://labinfrastructure.geo-x.net/laboratories/8). For their major and minor element compositions, bulk samples of drill gravel and scales were analyzed with XRF and ICP-MS, respectively. Salt precipitates were analyzed for dry loss and mineral composition using XRD

    Survey of critical raw materials in Tanzania East African Rift geothermal araes (2024)
    GFZ Data Services
    Details
    Publication Date: 2024-05-22
    Description: In autumn 2022, an expedition to Tanzania was undertaken within the framework of the research project “CRM-geothermal” and Scintific Priority Program (SPP) 2238 “Dynamics of Ore Metal Enrichment”. Within „CRM-geothermal“ we are looking for an environmentally friendly co-production of critical raw materials together with the provision of geothermal energy. In the EARS, high levels of rare earth elements (REE), Sr, Ba and Mg are expected in waters and solids in areas with alkaline volcanic rocks, while other critical elements, including helium, have been sought in other localities. In particular, the eastern branch is the most juvenile sector and has increased geothermal potential related to hot fluids migrating along permeable faults. Tanzania was crossed from north to south, along the eastern arm of the EARS, to collect gas, water, rock and sediment samples associated with natural hot springs, lakes and vents. On site, physical and chemical parameters were measured in-situ and documented together with the geology, infrastructure and the domestic use of the hot site. In the south, existing drill sites and geothermal development areas were visited and gas and water samples were taken from boreholes and rocks sampled from drill cores. The survey covered 13 sites, from Lake Natron in the north to Lake Malawi in the south (see map).

    Lead(II) biosorption experiments of the fungus Penicillium citrinum under geothermal conditions (2024)
    GFZ Data Services
    Details
    Publication Date: 2024-05-17
    Description: This dataset is the result of an experimental series that was carried out in September/October 2022 at GFZ German Research Centre for Geosciences, Potsdam, Germany to observe biosorption of lead under extreme conditions. Synthetic solutions, simulating the geothermal fluids from the Heemskerk geothermal power plant were were prepared in 30 ml glass vials (Rotalibo screw neck ND24 EPA). To prepare the stock solutions, sodium chloride (NaCl, 99.8 %, Cellpure, Merck, DE) was added at 265 g/L and Pb(II), in form of lead nitrate (Pb(NO3 )2 , Merck, DE), at 1 g/L to ultrapure water. To assess the impact of acetic acid on lead biosorption, two treatments were done: one without acetic acid and one where acetic acid (100 %, Merck, DE) was added at 60 mg/L. Finally, dead biomass of the fungus Penicillium citrinum was added in the samples at a concentration of 4 g/L (Wahab et al., 2017). The samples were incubated in an autoclave at a pressure of 8 bars on a rotative shaker. The temperature was set at 25 °C, 60 °C or 98 °C with three contact times (1, 2 and 3 h). All treatments were performed in triplicates. For each treatment, two controls without biomass were done. Control samples without the addition of NaCl were done in duplicate, at 25 °C and for 2 h. After incubation, samples were filtered through a 0.22 µm nitrocellulose filter (Sartorius Stedim Biotech, FR) to separate the biomass from the liquid. The biomass on the filters was dried for 24 h at 45 °C before being scraped from the filter and kept in a Falcon tube at room temperature.

    Chapter 5 Female agency, resourceful victimhood and heroines in migrant narrative (2024)
    Taylor & Francis | Routledge
    Details
    Publication Date: 2024-05-13
    Description: With a focus on migrant narratives, or the storytelling about migration, this volume considers the ways in which migration is and has been shaped by individual and collective experiences of agency, belonging and community. Driven by an agenda of deep listening, each chapter presents a narrative directly derived from qualitative research, an outline of the methodological framing as well as narrative analysis. Through close attention to the narrative, its performative aspects and its ruptures and silences, authors identify patterns and material in the fabric of such telling and retelling of stories that open up new perspectives on the migrant experience. This book develops a methodology of ""dwelling with stories"" that allows for sustained and slow interrogation of the migrant experience and the accompanying decisions that shape narratives around mobility across borders. Its structure is innovative by emphasising the migrant voice and reflecting on the scholars’ positionality, while also offering new theoretical contributions that will advance the field of narrative analysis. The book will appeal to academics, students and practitioners in a wide range of subject areas within the humanities and social sciences, including anthropology, sociology, human geography, migration/refugee/diaspora studies and oral history.

    Chapter 22 Towards a Better Understanding of Energy Poverty (2024)
    Taylor & Francis | Routledge
    Details
    Publication Date: 2024-05-13
    Description: Living with Energy Poverty: Perspectives from the Global North and South expands our collective understanding of energy poverty and deepens our recognition of the phenomenon by engaging with the lived experiences of energy-poor households across different contexts. Understanding the lived experience of energy poverty is an essential component in the design of any effort to alleviate what is fundamentally a deep-rooted, multi-faceted, wickedly complex problem. This requires a nuanced understanding of the causal factors and the research methods that can respond to the flexible spatial and temporal nature of the condition, as well as its wellbeing and justice implications. Drawing together the expertise and connectedness of authors from the Global South and North, this book presents novel approaches to understanding the often hidden forms of domestic energy deprivation. Case studies from 20 countries provide critical perspectives on this phenomenon while analysing the policy practices, government strategy, and sustainability implications of divergent manifestations. The book takes a multidimensional perspective, challenging the bias towards energy production and service provision, which often do not align with the aspirations and realities of energy households across global contexts, thus facilitating a useful dialogue on the nature of energy poverty. The book is a timely source for policymakers, practitioners, and scholars seeking fresh, diverse insights into the everyday reality of energy poverty and wanting to better understand the challenges a people-centred, just energy transition can present.

    Chapter 1 Getting real about monogamism (2023)
    Taylor & Francis | Routledge
    Details
    Publication Date: 2024-05-13
    Description: This chapter discusses monogamism as a type of systemic oppression enacted through ideas and practices that valorise monogamous people and relationships while systematically devaluing polyamorous and multi-partnered relationships. Instead of focusing on polyamorous/multi-partnered people, this chapter will apply the critical gaze of a sex and relationship therapist with polyamorous lived experience to examine and critique how psychotherapists behave toward polyamorous/multi-partnered people. Ansara explores how psychotherapists routinely engage in three common forms of monogamism: mononormative bias, couple-centric bias, and everyday monogamism. When examining these three forms of monogamism, Ansara explains how some ostensibly “neutral” and ubiquitous language, concepts, and clinical practices can enact monogamist oppression. This chapter then analyses how popular theoretical approaches to relationship counselling promote couple-centric bias and fail to address the key patterns, dynamics, and dilemmas in multi-partnered relationship systems. This includes an anti-racist, decolonial critique of Eurocentric approaches to Attachment Theory and the culture-bounded nature of mononormative biases. Finally, this chapter provides evidence-informed guidelines for anti-oppressive psychotherapeutic practice that can help polyamorous and multi-partnered people to strengthen attachment bonds, improve communications, and meet core emotional needs in their relational systems.
