CO2-capture and geological storage as a climate policy option : technologies, concepts, perspectives
(2007)
The idea of removing carbon dioxide from flue gas and industrial gas flows and putting it into suitable long-term storage sites is referred to as Carbon Capture and Storage (CCS). This publication provides a close look at this new line of technologies, describing its current status and outlining the prospects for development. The approach is both diagnostic and analytical, identifying the questions a technology assessment poses and showing the steps that need to be taken to implement CCS.
CCS is currently moving to the centre of climate policy discussion. Nonetheless this line of technologies is still the subject of controversial discussion. On the one hand there is a clear hope that these technologies will open up opportunities to use fossil fuels without harming the climate and thus make it possible to continue using oil, natural gas and above all coal even under a stricter climate regime. Accordingly, numerous R&D projects have been initiated all over the world, and various demonstration projects are at the planning or implementation stage. On the other hand, CCS (especially the storage part) has given rise to considerable scepticism from an ecological point of view.
Die vorliegende Broschüre setzt sich mit der Technologie der CO2-Abtrennung und Speicherung (CCS: Carbon Capture and Storage) auseinander. Sie bereitet den heute verfügbaren Sachstand auf und beschreibt die Entwicklungsperspektiven und Potenziale. Sie geht dabei sowohl diagnostisch als auch analytisch vor und zeigt die noch offenen Fragen für die Bewertung dieser Technologielinie sowie die noch notwendigen Handlungsschritte für ihre Umsetzung auf.
The analysis of different global energy scenarios in part I of the report confirms that the exploitation of energy efficiency potentials and the use of renewable energies play a key role in reaching global CO2 reduction targets. An assessment on the basis of a broad literature research in part II shows that the technical potentials of renewable energy technologies are a multiple of today's global final energy consumption. The analysis of cost estimates for renewable electricity generation technologies and even long term cost projections across the key studies in part III demonstrates that assumptions are in reasonable agreement. In part IV it is shown that by implementing technical potentials for energy efficiency improvements in demand and supply sectors by 2050 can be limited to 48% of primary energy supply in IEA's "Energy Technology Perspectives" baseline scenario. It was found that a large potential for cost-effective measures exists, equivalent to around 55-60% of energy savings of all included efficiency measures (part V). The results of the analysis on behavioural changes in part VI show that behavioural dimensions are not sufficiently included in energy scenarios. Accordingly major research challenges are revealed.
The book shows that the implementation of a sustainable energy strategy in Iran provides the opportunity for further economic and social development. In this context, the aim of the book is to provide some of the analyses needed to rethink the country’s energy strategy and to grasp the chances. The authors hope to make a contribution to the emerging and rapidly growing discussion on better energy alternatives and the respective opportunities for investment, innovation and modernization. The work presented in the book should provide ideas for such opportunities and create a vision of how this could contribute towards developing a more sustainable, efficient and prosperous future energy system for Iran.
The book is based on long-term academic cooperation between Iranian researchers from several universities and the Iranian Energy Association and German researchers from the Wuppertal Institute, Büro Ö-quadrat and the University of Osnabrück. The book in hand is an important result of the collaboration. So its publication lends itself to taking stock of these twelve years of continued cooperation.
Energiebalance - optimale Systemlösungen für erneuerbare Energien und Energieeffizienz : Endbericht
(2009)
Iran ist eines der größten Erdölförderländer und verfügt über riesige Erdgasreserven - und hat doch ein Energieproblem. Im Zuge des steigenden Energieverbrauchs droht das Land zum Energieimporteur zu werden. Ein Ausweg wird in der Kernenergie gesucht, was durch den Fokus auf den militärischen Aspekt ein großes Konfliktpotenzial birgt.
In seiner Dissertation entwickelt Nikolaus Supersberger "Szenarien eines diversifizierten Energieangebots in OPEC-Staaten am Beispiel Irans - Strategien eines auf klimaschonenden Energieträgern basierenden Umstiegs". Die Ergebnisse sind in diesem Reader zusammengefasst.
Es wird deutlich, dass die Kernenergie für eine langfristig sichere Energieversorgung nicht notwendig ist. Er zeigt das große Potenzial zur Nutzung erneuerbarer Energien und dass eine vollregenerative Stromerzeugung möglich ist. Zudem wird offenbar, dass der Einsatz erneuerbarer Energien und von Energieeffizienz die Ölexporte Irans wie auch anderer OPEC-Staaten deutlich strecken würde.
