In this brochure, WISIONS focuses on how sustainable energy use can support poverty reduction. WISIONS presents projects from Namibia, Brazil, the Philippines and India that have been successfully implemented, with the intention of further promoting the particular approaches used by these projects. Using a key number of internationally accepted criteria, the main consideration for the selection of the projects was energy and resource efficiency with social aspects being of high additional relevance. The assessment of the projects also included the consideration of regional factors acknowledging different needs and potentials.
Solar-Sparprojekt macht Schule : Privatkapital finanziert erneuerbare Energien in den Kommunen
(2007)
For the option of “carbon capture and storage”, an integrated assessment in the form of a life cycle analysis and a cost assessment combined with a systematic comparison with renewable energies regarding future conditions in the power plant market for the situation in Germany is done. The calculations along the whole process chain show that CCS technologies emit per kWh more than generally assumed in clean-coal concepts (total CO2 reduction by 72-90% and total greenhouse gas reduction by 65-79%) and considerable more if compared with renewable electricity. Nevertheless, CCS could lead to a significant absolute reduction of GHG-emissions within the electricity supply system. Furthermore, depending on the growth rates and the market development, renewables could develop faster and could be in the long term cheaper than CCS based plants. Especially, in Germany, CCS as a climate protection option is phasing a specific problem as a huge amount of fossil power plant has to be substituted in the next 15 years where CCS technologies might be not yet available. For a considerable contribution of CCS to climate protection, the energy structure in Germany requires the integration of capture ready plants into the current renewal programs. If CCS retrofit technologies could be applied at least from 2020, this would strongly decrease the expected CO2 emissions and would give a chance to reach the climate protection goal of minus 80% including the renewed fossil-fired power plants.
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.

Inducing the international diffusion of carbon capture and storage technologies in the power sector
(2007)
Although CO2 capture and storage(CCS) technologies are heatedly debated, many politicians and energy producers consider them to be a possible technical option to mitigate carbon dioxide from large-point sources. Hence, both national and international decision-makers devote a growing amount of capacities and financial resources to CCS in order to develop and demonstrate the technology and enable ist broad diffusion.The presented report concentrates on the influence of policy incentives on CCS diffusion and examines the following research question: Which policy strategy is needed to stimulate the international diffusion of carbon capture and storage technologies in the power sector? Based on the analysis of innovation-specific (e.g. CCS competitiveness and compatibility), market-related (e.g. national CO2 discharges and storage capacities) and institutional determinants (e.g. existing national and international policy frameworks) of CCS diffusion, the paper discusses the suitability of various national and international policy instruments to induce the international deployment of CCS. Afterwards, three CCS diffusion paths are derived from fundamentally different carbon stabilisation scenarios which include climate policy measures to stimulate the adoption of CO2 mitigation technologies.
