A promising candidate that may follow conventional vehicles with internal combustion engines combines hydrogen from regenerative sources of energy, fuelcells and an electric drive train. For early fleets introduced the refuelling infrastructure needs to be in place at least to the extent of the vehicles operational reach. The question arises which strategies may help to keep initial hydrogen and infrastructure cost low? Industrial production, distribution and use of hydrogen is well-established and the volumes handled are substantial. Even though today's industrialhydrogen is not in tune with the long-term sustainable vision, hydrogen production and infrastructure already in place might serve as a nucleus for putting that vision into practice. This contribution takes stock of industrial production and use of hydrogen in North Rhine-Westphalia based on a recently finalized project. It demonstrates to which extent industrial hydrogen could be used for a growing number of vehicles and at which time additional capacity might need to be installed.
This paper reviews the current EU policy framework in view of its impact on hydrogen and fuel cell development. It screens EU energy policies, EU regulatory policies and EU spending policies. Key questions addressed are as follows: to what extent is the current policy framework conducive to hydrogen and fuel cell development? What barriers and inconsistencies can be identified? How can policies potentially promote hydrogen and fuel cells in Europe, taking into account the complex evolution of such a potentially disruptive technology? How should the EU policy framework be reformed in view of a strengthened and more coherent approach towards full deployment, taking into account recent technology-support activities? This paper concludes that the current EU policy framework does not hinder hydrogen development. Yet it does not constitute a strong push factor either. EU energy policies have the strongest impact on hydrogen and fuel cell development even though their potential is still underexploited. Regulatory policies have a weak but positive impact on hydrogen. EU spending policies show some inconsistencies. However, the large-scale market development of hydrogen and fuel cells will require a new policy approach which comprises technology-specific support as well as a supportive policy framework with a special regional dimension.
In this classic collection, some of the world's most eminent critics of development review the key concepts of the development discourse. Each essay examines one concept from a historical and anthropological point of view, highlights its particular bias, and exposes its historical obsolescence and intellectual sterility. The authors argue that a bidding farewell to the whole Euro-centric development idea is urgently needed, in order to liberate people’s minds - in both North and South - for bold responses to the environmental and ethical challenges now confronting humanity. The combined result forms a must-read invitation to experts, grassroots movements and students of development to recognize the tainted glasses they put on whenever they participate in the development discourse.
Renewable energy can become the major energy supply option in low-carbon energy economies. Disruptive transformations in all energy systems are necessary for tapping widely available renewable energy resources. Organizing the energy transition from non-sustainable to renewable energy is often described as the major challenge of the first half of the 21st century. Technological innovation, the economy (costs and prices) and policies have to be aligned to achieve full renewable energy potentials, and barriers impeding that growth need to be removed. These issues are also covered by IPCC's special report on renewable energy and climate change to be completed in 2010. This article focuses on the interrelations among the drivers. It clarifies definitions of costs and prices, and of barriers. After reviewing how the third and fourth assessment reports of IPCC cover mitigation potentials and commenting on definitions of renewable energy potentials in the literature, we propose a consistent set of potentials of renewable energy supplies.

Mobil zu sein bedeutet in unseren Großstädten in vielen Situationen eine Dienstleistung zu nutzen: die Straßenbahn oder der Bus fahren uns zügig und ohne Parkplatzsorgen zum Einkaufen, das Taxi bringt uns nach der Party sicher nach Hause. Diese Mobilitätsdienstleistungen sind feste Bestandteile unseres Verkehrssystems und werden ergänzt durch weitere Elemente, z. B. Reise-Informationen, die uns helfen, Wege zu finden und pünktlich ans Ziel zu kommen, oder Kombinations-Angebote, wie die Möglichkeit, bei Regen das Fahrrad mit in die Bahn zu nehmen. Städtische Mobilität ist dennoch stark geprägt vom Autoverkehr, mit vielfältigen negativen Einflüssen auf Mensch, Umwelt und Stadtbild. Aus Sicht des Gesundheits- Umwelt- und Klimaschutzes sowie zur Verbesserung der Lebensqualität in unseren Städten ist es sinnvoll, vermehrt Mobilitätsdienstleistungen in Anspruch zu nehmen. Die vorliegende Arbeit untersucht die Nutzung von Mobilitätsdienstleistungen in drei deutschen Großstädten. Gefragt wird danach, wer die Nutzer dieser Dienstleistungen sind, welche Motive hinter der Nutzung stehen und welche Schwierigkeiten mit der Nutzung verbunden sind. Auf Basis von Befragungen wird die Bedeutung von Dienstleistungen für die städtische Mobilität insgesamt ermittelt. Es wird untersucht, welche Chancen für eine zukünftig intensivere Nutzung der Mobilitätsdienstleistungen bestehen und welche Voraussetzungen dafür notwendig sind.
Cleaning up the CDM
(2010)
Klimawandel, Rohstoffknappheit, Finanz- und Wirtschaftskrise - die Liste der dringend zu lösenden, globalen Probleme ist lang. Sie greifen ineinander, befeuern sich gegenseitig und sind Symptome einer Krise des gesamten Systems. Die Gesellschaft steht vor einem Umbruch. Doch wie können wir den notwendigen Wandel erfolgreich mitgestalten? Es ist an der Zeit, sich mit Veränderungsprozessen zu befassen: Nur wer versteht, wie dieser Wandel abläuft, kann die Richtung der Veränderungen auch beeinflussen. In diesem Buch werden die wesentlichen Erfolgsfaktoren für Veränderungen untersucht und gezeigt, woran sich Veränderungsprofis aus der Praxis und der Wissenschaft orientieren. Die Autorin entwickelt ein Modell, mit dem Politik, Verbände oder Nichtregierungsorganisationen Veränderungen in der Gesellschaft erfolgreicher anstoßen und gestalten können.
This study provides insight into the feasibility of a CO2 trunkline from the Netherlands to the Utsira formation in the Norwegian part of the North Sea, which is a large geological storage reservoir for CO2. The feasibility is investigated in competition with CO2 storage in onshore and near-offshore sinks in the Netherlands. Least-cost modelling with a MARKAL model in combination with ArcGIS was used to assess the cost-effectiveness of the trunkline as part of aDutch greenhouse gas emission reduction strategy for the Dutch electricity sector and CO2 intensive industry. The results show that under the condition that a CO2 permit price increases from €25 per tCO2 in 2010 to €60 per tCO2 in 2030, and remains at this level up to 2050, CO2 emissions in the Netherlands could reduce with 67% in 2050 compared to 1990, and investment in the Utsira trunkline may be cost-effective from 2020–2030 provided that Belgian and German CO2 is transported and stored via the Netherlands as well. In this case, by 2050 more than 2.1 GtCO2 would have been transported from the Netherlands to the Utsira formation. However, if the Utsira trunkline is not used for transportation of CO2 from Belgium and Germany, it may become cost-effective 10 years later, and less than 1.3 GtCO2 from the Netherlands would have been stored in the Utsiraformation by 2050. On the short term, CO2 storage in Dutch fields appears more cost-effective than in the Utsira formation, but as yet there are major uncertainties related to the timing and effective exploitation of the Dutch offshore storage opportunities.
Life Cycle Assessment (LCA) has matured over the past decades and become part of the broader field of sustainability assessment. To strengthen LCA as a tool and eventually increase its usefulness for sustainability decision-making, it is argued that there is a need to expand the ISO LCA framework by integration and connection with other concepts and methods. This paper explores the potential options for deepening and broadening the LCA methodologies beyond the current ISO framework for improved sustainability analysis. By investigating several environmental, economic and social assessment methods, the paper suggests some options for incorporating (parts of) other methods or combining with other methods for broadening and deepening the LCA.
Comparative analysis of environmental impacts of maize-biogas and photovoltaics on a land use basis
(2010)
This study aims to stimulate the discussion on how to optimize a sustainable energy mix from an environmental perspective and how to apply existing renewable energy sources in the most efficient way. Ground-mounted photovoltaics (PV) and the maize-biogas-electricity route are compared with regard to their potential to mitigate environmental pressure, assuming that a given agricultural area is available for energy production. Existing life cycle assessment (LCA) studies are taken as abasis to analyse environmental impacts of those technologies in relation to conventional technology for power and heat generation. The life-cycle-wide mitigation potential per area used is calculated for the impact categories non-renewable energy input, green house gas (GHG) emissions, acidification and eutrophication. The environmental performance of each system depends on the scenario that is assumed for end energy use (electricity and heat supply have been contemplated). In all scenarios under consideration, PV turns out to be superior to biogas in almost all studied impact categories. Even when maize is used for electricity production in connection with very efficient heat usage, and reduced PV performance is assumed to account for intermittence, PV can still mitigate about four times the amount of green house gas emissions and non-renewable energy input compared to maize-biogas. Soil erosion, which can be entirely avoided with PV, exceeds soil renewal rates roughly 20-fold on maize fields. Regarding the overall Eco-indicator 99 (H) score under most favourable assumptions for the maize–biogas route, PV has still a more than 100% higher potential to mitigate environmental burden. At present, the key advantages of biogas are its price and its availability without intermittence. In the long run, and with respect to more efficient land use, biogas might preferably be produced from organic waste or manure, whereas PV should be integrated into buildings and infrastructures.
Energierevolution : Effizienzsteigerung und erneuerbare Energien als neue globale Herausforderung
(2010)
Die Energieversorgung der Zukunft ist unsicher. Ein radikaler Kurswechsel steht uns bevor: Noch dominieren global die fossilen Energieträger Öl, Kohle und Erdgas das Energiesystem. Doch ihr Ende ist absehbar: Sie verursachen politische und gesellschaftliche Konflikte, Preisrisiken und beeinflussen das Klima in verheerender Weise. Die Atomenergie ist keine Alternative, sie verlagert Risiken statt sie abzubauen. Dieses Buch zeigt, wie eine Energieversorgung ohne fossile Energieträger und ohne Uran gelingen kann. Es verdeutlicht, vor welchen globalen Herausforderungen die Industrie-, Schwellen- und Entwicklungsländer stehen. Es benennt die Technologien und Instrumente, die global Energieeffizienz und erneuerbaren Energien zum Durchbruch verhelfen können. Nur so können Risiken verringert und kann der Energiehunger der Schwellen- und Entwicklungsländer nachhaltig gestillt werden. Die hier skizzierte sanfte Energierevolution ist der Schlüssel zu einem weltweit sozial- und naturverträglichen Energiesystem.

Renania del Norte-Westfalia (RNW) es el mayor estado federal (land) de la República Federal de Alemania. Hasta la década de 1970, la región del Rin-Ruhr, con una población de unos 12 millones de habitantes y una potente industria química, del carbón y del acero, se vio afectada por graves problemas de contaminación. En los años setenta, la protección medioambiental apareció en las agendas políticas nacionales e internacionales. Los gobiernos federales y el estatal lanzaron múltiples intervenciones legislativas y económicas para limpiar ríos, suelos y aire. Como resultado, surgió una ecoindustria muy competitiva. En este artículo, se resumen las características de las ecoindustrias y se describe el cambio estructural de la región del Ruhr. Asimismo, centrándose en el mesonivel y empleando los ejemplos de la gestión energética y la gestión municipal de residuos, se destacan los puntos fuertes y los puntos débiles de las políticas económicas regionales de clusters que apoyan las ecoindustrias en RNW.
In 1990 a sovereign wealth fund was founded in Norway in which the country invests surpluses from oil and gas industry sales. The fund is designed to secure the state's ability to act in a post-petroleum era. At the end of the 1990's the voice of Norwegian civil society insisted that the sovereign wealth fund should not only ensure intergenerational justice, but should also contribute to the implementation of values and norms of the present country. At the end of 2004 the parliament finally agreed upon ethical regulations for the investment of the sovereign wealth fund. Now the second largest sovereign wealth fund in the world only invests in businesses that adhere to those ethical regulations. In the present paper, I seek to illustrate the emergence and outcomes of this new development in the Norwegian sovereign wealth fund.
