Energy from the Earth

Publisher: vdf Hochschulverlag AG
ISBN: 3728136549

Languages : en
Pages : 526
Book Description
Switzerland's Energy Strategy 2050 requires energy efficiency to be substantially improved, the proportion of fossil fuels in the energy supply to be considerably reduced, and nuclear power to be phased out, while meeting highly ambitious climate protection targets. One of the core implications is the need for a massive increase of the use of renewable sources for electricity generation. In this context, the Swiss Federal Office of Energy (SFOE) estimates that by 2050 deep geothermal energy could contribute 4–5 TWh per year to electricity generation in Switzerland, which would be a substantial contribution to a projected annual power need of 60 TWh. Geothermal energy is attractive because of the very large scale of the resource, its expected relatively low CO2 emissions, and its reliable, all-day domestic availability. However, the future contribution of deep geothermal energy is subject to major uncertainties: How much of this resource can be exploited and at what economic cost? What are the environmental and risk-related externalities that the public must be willing to bear? How does its overall performance compare to competing energy resources? And will the regulatory framework and public acceptance be sufficient to allow geothermal energy to provide a significant contribution? By way of this major interdisciplinary study, already considered a work of reference, TA-SWISS provides answers to these questions in a comprehensive and balanced way, thereby supplying a sound basis for stakeholder decision-making.

On the dissolution, precipitation and transport processes in sulphatic swelling rocks
Author: Konstantinos Serafeimidis
Publisher: vdf Hochschulverlag AG
ISBN: 3728136468
Category : Technology & Engineering
Languages : en
Pages : 250
Book Description
Sulphatic claystones are among the most problematic rocks in tunnelling due to their distinctive swelling properties. They are known to have caused severe damage, for example, to numerous tunnels excavated in the Gypsum Keuper formation. The repairs were extremely costly and time-consuming, and often provided only a temporary solution. The setbacks experienced in tunnelling through Gypsum Keuper may be attributed, among other things, to our limited knowledge of the macroscopic principles governing the swelling process and the underlying microscopic mechanisms. The issues in question have formed the focal point of long-standing research in the Chair of Underground Construction at ETH Zurich. A series of theoretical and experimental research projects are being conducted to investigate the interactions between chemical reactions, transport processes and the observed macroscopic behaviour. The objective of the investigations is to improve our understanding of swelling processes in order to yield a scientifically established basis for design. This work has achieved important progress towards this objective. It has systematically and comprehensively analysed the thermodynamics and the kinetics of the chemical reactions involved in the swelling process, as well as their interplay with advective and diffusive ion transport. The topic is of great value in terms of further investigation in this area.

Global Change and Protected Areas

Languages : en
Pages : 510
Book Description
High mountains can be considered as particularly appropriate environments to detect effects ofclimate change on natural biocoenoses in a global scale for the following reasons: Firstly, ecosystems at the l- temperature limits of plant life are generally thought to be especially sensitive to climate change [1][2][3]. An already ongoing upward shift of vascular plants at high summits in the Alps, determined by the Austrian IGBP-research [4][5][6][7][8], is most likely a response to the atmospheric warming since the 19th century. Secondly, high mountains still comprise the most natural ecosystems in many countries, being largely untouched by human settlements and agricultural influences, Therefore, climatic effects on ecosystems can be studied without masking effects from human land use. Thirdly, high mountain ranges are present in virtually every major zonobiome of the earth. The research initiative GLORIA aims to establish an urgently needed global monitoring network, by using high mountain ecosystems as sensitive indicators, as required in the “IGBP-Mountain Workplan” [9]. Moreover, a deeper understanding of assemblagemechanisms andassemblage processes in vegetation patterns as a contribution to ecological theory can be expected. This paper gives a short general overview about GLORIA and a first outline about the concept, method, and some few results of the “Multi Summit-Approach”, one of the basic intentions within the proposed network. It aims to encourage the involvement of high mountain researchers and research co-ordinators in a detailed discussion of the proposed research activities and in a co-operation within the planned global monitoring network.
