The brochure summarises the project's objectives and methodological approach, its key findings as well as conclusions. Both case studies have shown that technological solutions for low carbon development should be embedded in a well-developed institutional framework to foster their deployment and implementation. Therefore, recommendations for Wuxi include examples of innovative and integrated technical projects for increasing energy and resource efficiency, combining them with recommendations for the development of institutional frameworks. One element of such a framework could be a local energy agency in Wuxi, which would offer support and expertise to potential investors in low carbon technologies. Also for the German pilot region, the brochure offers concrete recommendations how to facilitate low carbon planning within the region.
Prospects of carbon capture and storage (CCS) in India's power sector : an integrated assessment
(2014)
Objective: The aim of the present article is to conduct an integrated assessment in order to explore whether CCS could be a viable technological option for significantly reducing future CO2 emissions in India. Methods: In this paper, an integrated approach covering five assessment dimensions is chosen. However, each dimension is investigated using specific methods (graphical abstract).
Results: The most crucial precondition that must be met is a reliable storage capacity assessment based on site-specific geological data since only rough figures concerning the theoretical capacity exist at present. Our projection of different trends of coal-based power plant capacities up to 2050 ranges between 13 and 111 Gt of CO2 that may be captured from coal-fired power plants to be built by 2050. If very optimistic assumptions about the country's CO2 storage potential are applied, 75 Gt of CO2 could theoretically be stored as a result of matching these sources with suitable sinks. If a cautious approach is taken by considering the country's effective storage potential, only a fraction may potentially be sequestered. In practice, this potential will decrease further with the impact of technical, legal, economic and social acceptance factors. Further constraints may be the delayed commercial availability of CCS in India, a significant barrier to achieving the economic viability of CCS, an expected net maximum reduction rate of the power plant’s greenhouse gas emissions of 71-74%, an increase of most other environmental and social impacts, and a lack of governmental, industrial or societal CCS advocates.
Conclusion and practice implications: Several preconditions need to be fulfilled if CCS is to play a future role in reducing CO2 emissions in India, the most crucial one being to determine reliable storage capacity figures. In order to overcome these barriers, the industrialised world would need to make a stronger commitment in terms of CCS technology demonstration, cooperation and transfer to emerging economies like India. The integrated assessment might also be extended by a comparison with other low-carbon technology options to draw fully valid conclusions on the most suitable solution for a sustainable future energy supply in India.
Industry

Das Ziel dieser Untersuchung war, das technische Regelleistungspotenzial von BHKW in Deutschland für die Jahre 2010, 2020 und 2030 zu bestimmen. Der Fokus lag auf den kleineren Leistungsbereichen für die objektscharfe Versorgung von Wohngebäuden sowie von gewerblichen Objekten (Nichtwohngebäuden). Ergänzend wurde exemplarisch eine größere BHKW-Anlage mit Wärmenetz und ein industrieller Anwendungsfall untersucht.
The EU has set itself ambitious targets with regards to a significant reduction of its greenhouse gas emissions and has presented roadmaps depicting an overall decarbonisation of its economy by the middle of the century. In this context European policymakers and stakeholders are currently discussing the targets and the level of ambition of the 2030 climate and energy policy framework. The Commission is expected to present its own vision for the further development of the energy and climate policy framework in its White Paper "For a 2030 climate and energy policy framework". At this decisive point in the political debate the Wuppertal Institute presents a brief working paper that analyses some of the analytical work - particularly the underlying energy and GHG emission scenarios - behind the Commission's proposals to be presented in the forthcoming White Paper.
The role of gender concerns in the planning of small-scale energy projects in developing countries
(2014)
Il Wuppertal Institute ha condotto uno studio per valutare quali materiali sono da considerare critici in relazione al previsto incremento di energie rinnovabili in Germania. I problemi relativi a materiali come terre rare e vanadio riguardano la dipendenza da pochi paesi fornitori e gli usi competitivi.
Energieszenarien können in der Diskussion zur Energiewende Orientierung bieten und Entscheidungen unterstützen. Fehlende Transparenz sowie die Vielzahl und Heterogenität der verfügbaren Studien erschweren es jedoch, diese angemessen zu interpretieren. Das vorliegende Diskussionspapier bietet Nutzern eine Hilfestellung und leistet einen Beitrag zur Entwicklung eines grundsätzlichen Analyse- und Interpretationsrahmens, der auch in anderen thematischen Bereichen angewendet werden kann.
Among the factors that decelerate progress of CCS demonstration and deployment is the lack of public acceptance of local projects in Germany as well as in other countries. The study presented here aims to take the issue of public CCS perceptions further by empirically investigating the relevance of different specifications of the three main steps of the CCS chain, i.e. capture, transport and storage. An experimental approach is chosen and applied in an online survey with a representative sample from Germany with 1830 participants. With regard to possible CO2 sources we varied whether the CO2 of a specific setting is captured i) as part of an energy-intensive industry process (e.g. production of steel or cement), ii) from a power plant running on biomass, or iii) a coal-fired power plant. For transport, half of the settings described made reference to transport of CO2 via pipelines, the other half did not provide information about transport. With regard to storage the setting descriptions i) either explained that CO2 can be stored in saline aquifers, ii) can be used to enhance gas production from an emptying natural gas field or iii) can be stored in a depleted natural gas field. We find that overall the average of the ratings for perception of the settings fall into the neutral part of the answering scale. If the source of CO2 is a coal-fired power plant the setting is perceived less positively than if it includes biomass or industry. A significant interaction effect between transport and storage specifications is observed. This points out that storage in saline aquifers is perceived more negatively than a combination with enhanced gas recovery while storage in a depleted natural gas field is rated less positively if a pipeline is mentioned and more positively if no transport option is mentioned.
