Deep Geothermal Energy

Abstract. Geothermal exploration will help moving towards a low-carbon economy and provide a basis for green and sustainable growth. The development of new practical, reliable methods for geophysical characterisation of a reservoir has the potential to facilitate a broader application of deep geothermal energy. At the Groß Schönebeck in-situ laboratory, a unique vertical seismic profiling (VSP) dataset was recorded in two 4.3 km deep geothermal boreholes using fibre optic cables in early 2017. The experiment set-up consisted of 61 vibrator points organised in a spiral pattern around the well site to ensure a proper azimuth distribution in the target reservoir section. Data were processed using a standard workflow for VSP. As a result, a detailed 3-dimensional 0.75 × 1 × 4.5 km size image around the existing boreholes was created using the Kirchhoff migration algorithm with restricted aperture. The imaging resolved small-scale features in the reservoir essential for the future exploration of the geothermal research site. Borehole data with vertical resolution up to 16 m revealed the existing depth variations of the Elbe basis sandstone horizon at 4.08–4.10 km depth and indications of an unconformity in the area where we expect volcanic rocks. In addition, in the borehole data a complex interlaying with numerous pinch outs in the Upper Rotliegend reservoir section (3.8 to 4 km depth) was discovered. Thereby, we demonstrate that wireline fibre optic data can significantly contribute to exploration by providing an efficient and reliable method for deep geothermal reservoir imaging.

Carbon Economy

In facing with increasingly serious climate and energy crisis, the society came across with contradictions of environmental crisis and economic development. As to the solution, the development of low-carbon economy is an effective one. By analyzing the tendency of global economic and the necessity of low-carbon agriculture in China, the author raises the opinion that to build low-carbon synthetically integrated system with the agricultural enterprises as the core unit, together with main associations in the industry and synergetic associations in environment, and this is an important way for agricultural enterprises to fulfill their strategic transformation and to achieve sustainable growth. In this paper, theories and integration elements of this system will be analyzed and conceptual model will be constructed and analyzed.

Abstract Recent scientific findings have underscored the need for a rapid global decarbonization. Yet, atmospheric concentrations of greenhouse gases continue to rise despite vast investments in small-scale renewable energy. Meanwhile, the prolonged international climate negotiations have yet to deliver effective mitigation action. By problematizing the issue of scalability and taking into consideration a realist analysis of international relations, this article suggests 1) that national transitions to a low-carbon economy can only serve as stepping-stones to global decarbonization if they contribute to the development of scalable technologies that are significantly cheaper than existing fossil alternatives and 2) that the current diplomatic gridlock can only be broken by technological innovation that severs the link between economic prosperity and greenhouse gas emissions, and thus also severs the link between decarbonization and military power.

SummarySubject and purpose of work: The subject of this analysis and evaluation is the use of renewable energy sources in Poland, particularly in the Lubelskie Voivodeship, as a peripheral region. The purpose of this paper is to identify the role and evaluate the scale and effects of using renewable energy sources (RES), as well as the availability and absorption of financial resources for RES promotion.Materials and methods: The data were obtained from the Office of the Ruda-Huta Commune, the Regional Operational Programme Department of the Marshal Office of the Lubelskie Voivodeship in Lublin and the Department of European Funds of the Ministry of Energy, as well as Statistics Poland (GUS) and the literature on the subject.Results: In Poland the proportion of energy from renewable sources to the total primary energy generated increased in 2012-2018 from 11.73% to 14.46%. A new phenomenon, which has been highly significant for the development of this sector, is the use of innovative, small-scale technologies of energy generation from renewable sources, which created the foundations for the growth of a citizens’ energy sector, based on the initiative of the citizens and their communities. The use of RES contributes to reduced expenditures on the purchase of energy carriers and constitutes an effective method of implementing plans for developing a low-carbon economy and reducing low-stack emissions.Conclusions: The continuing disparities between the regions point to the need for active structural intervention to maintain economic, social and territorial cohesion, particularly in areas which are considered peripheral and have a very low GDP per capita. One of the preferred directions should be to support the use of RES.

The integration of renewable energy sources into the electricity system can contribute to the development of a low-carbon economy. However, due to the intermittency and non-programmability of these sources, problems related to the management of local electricity grids may occur. A possible solution or limitation to these issues is given by the electrical storage. In addition, in the next future, domestic micro-grids are expected to play a fundamental role in electric power networks, driving both the academic and industrial research interests in developing highly efficient and reliable conversion and storage technologies. In this study, the behavior of a small-scale hybrid energy system for hydrogen production and storage has been predicted, by means of a developed calculation model, and the operational strategy of the system has been optimized with the aim to maximize the hydrogen production. In addition, with the aim to maximize the overall solar-to-hydrogen chain efficiency, the whole system model has been applied to different operating scenarios, to identify the optimal management strategy to control it.

The main objective of the European Union's (EU) industrial policy is to increase the competitiveness of European industry so that it can continue to play its role as a driver of sustainable growth and employment in Europe. In order to provide better framework conditions for the EU industry, different strategies have been adopted. At the beginning of the current programming period (2014-2020), the European Commission (EC) calls on Member States to recognize industry's leading role as a factor for economic growth, employment and competitiveness through measures in all policy areas. The new approach to industrial policy, formulated in the Europe 2020 strategy, aims at boosting EU competitiveness, generating growth, creating jobs and enabling the transition to low-carbon economy and efficient use of resources. The EU-prepared and European-level discussion of a "Renewed EU Strategy for Industrial Policy" of 2017 is a first step towards the development of an EU-oriented industrial strategy that needs a common approach based on the competitive advantages of the economy and businesses, taking into account the European model of high environmental and social standards and setting an ambitious long-term vision for industry over a decade and beyond a future for the benefit of citizens and the economy. Industrial policy should not protect aging businesses, but should eliminate unfair commercial practices and draw up an action plan in line with strategic objectives. It should become part of the “Sovereign Europe Program.”
