Utilization of plastic wastes in a blast furnace - a contribution to ecological and economical recycling of plastic wastes; Kunststoffverwertung im Hochofen - ein Beitrag zum oekologischen und oekonomischen Recycling von Altkunststoffen  

Energy Technology Data Exchange (ETDEWEB)

This article describes the utilization of plastic wastes in a blast furnace. The plastic waste is a substitution for petroleum and coal as a raw material for synthesis gas production. The synthesis gas is the reducing agent in the blast furnace for the reduction of iron ores. You can find here an ecological and economical analysis of this process in comparison to the utilization of petroleum and coal. (SR)

Requirements, design and development of a latent heat store for use in vehicles; Anforderungen, Konzeption und Entwicklung eines Latentwaermespeichers fuer den Kraftfahrzeugeinsatz  

Energy Technology Data Exchange (ETDEWEB)

With the development of the latent heat store and its inclusion in the conventional heating control of cars, success has been achieved both in increasing comfort and in making an important contribution to safety of driving. Great store is set in development of the system on its environmental friendliness, for example by the thorough use of environmentally friendly and reusable materials. This also means the use of clean materials. It was shown that the latent heat store (apart from the aspects of comfort and safety of driving) can also make a contribution to saving fuel and reducing the exhaust gas. The sum total of the advantages makes it clear that the latent heat store introduced here is a very environmentally friendly system with multi-functional properties. (orig.)

Offshore wind power. Position paper of the Minister of the Environment; Windenergienutzung auf See. Positionspapier des Bundesministeriums fuer Umwelt, Naturschutz und Reaktorsicherheit zur Windenergienutzung im Offshore-Bereich  

Energy Technology Data Exchange (ETDEWEB)

The position paper will provide the basis for further strategies on offshore wind power development in consideration of ecological and conservation aspects. [German] Das Positionspapier des Bundesministeriums fuer Umwelt, Naturschutz und Reaktorsicherheit (BMU) einschliesslich des Umweltbundesamtes (UBA) und des Bundesamtes fuer Naturschutz (BfN) ist Ergebnis der Arbeiten der BMU-Projektgruppe 'Windenergienutzung im Offshore-Bereich im Hinblick auf die BMU-Anliegen'. Es beschreibt den derzeitigen Stand einer Strategie zur umwelt- und naturvertraeglichen Erschliessung der Windenergienutzung auf See (Offshore). Es bildet die Grundlage fuer die Weiterentwicklung dieser Strategie und dabei insbesondere zur Abstimmung mit den Anliegen anderer Bundesressorts und den Kuestenlaendern, sowie zur intensiveren Einbeziehung beteiligter Verbaende und Fachkreise. Vor dem Hintergrund der zur Genehmigung eingereichten Antraege fuer Offshore-Windparks, mangelnder Erfahrung der ...

Structure of energy supply, energy analysis, projections for energy demand development and for emission-reducing energy carrier application in powered vehicles in the district Schmalkalden-Meiningen; Struktur der Energieversorgung, Energieanalysen, Prognosen zur Energiebedarfsentwicklung und zum emissionsmindernden Energietraegereinsatz fuer Kraftfahrzeuge im Landkreis Schmalkalden-Meiningen  

Energy Technology Data Exchange (ETDEWEB)

The present publication is based on facts, data, knowledge and projects, which have been incorporated in the development of an energy concept for the district Schmalkalden-Meiningen. The energy concept of a district is a concept oriented at action on and realisation of mid-term and long term decisions in the fields of energy policy, economy and ecology, which must be taken by municipal and economic decision-making bodies. The energy concept accords with the targets of the Agenda 21, the environmental targets of the Federal Republic of Germany and of the Land Thuringia. Accepting this energy concept the district Schmalkalden-Meiningen shows its willingness to contribute to a lasting development in all fields of economy and ecology and thus does justice to its increasing responsibility. (orig.) [German] Die vorliegende Veroeffentlichung baut auf Fakten, Daten, Erkenntnissen und Projekten auf, die in die Erarbeitung des Energiekonzeptes fuer den Landkreis Schmalkalden-Meiningen ...

Isothermal refuelling of natural gas vehicles with condensed natural gas CNG; Isotherme Betankung von Erdgasfahrzeugen mit komprimiertem Erdgas CNG  

Energy Technology Data Exchange (ETDEWEB)

CNG vehicles suffer from an uncontrolled temperature rise of the gas inside the tank during the filling process and heat exchange with the environment leads to variable filling levels. A partly filled tank reduces the range of CNG vehicles and works as a impediment to the spreading of environmentaly more friendly CNG vehicles. The increase of the pressure inside the tank combined with a prolongation of the filling time beyond three minutes can reduce the deficit of the filling process. For economic reasons the time required for refuelling should be as short as possible without the need to operate the filling station with a critical pressure. To meet this target the current technique requires further improvement. (orig.) [Deutsch] Die betriebliche Praxis bei Tankvorgaengen von Erdgasfahrzeugen zeigt, dass waehrend des Tankvorganges die Temperatur des getankten Erdgases im Fahrzeugtank ansteigt. Waehrend und nach Beendigung des Tankvorganges findet ein Temperaturausgleich mit der ...

'Zoxy' - the zinc-air high energy battery system: with decentral charging infrastructure; ''Zoxy'' - das Zink-Luft-Hochenergiebatterie-System mit dezentraler Lade-Infrastruktur  

Energy Technology Data Exchange (ETDEWEB)

Storing electrical energy in batteries is not a viable option for sustaining a country's energy economy. The mass and volume, as well as the costs, of electrochemical components required for this would be beyond all reason. Nevertheless, in certain applications the storage of electrical energy does have significant advantages over other technologies. For example, electrically powered road vehicles emit no exhaust fumes and very little noise at their place of operation. In this way they contribute substantially to air and noise pollution control in urban areas. Photovoltaic applications permit environmentally friendly electricity applications in places remote from the public grid where conventional solutions are prohibitively expensive. More than in the past, battery systems today have to meet a wide range of technical, economic and ecological requirements in order to be marketable. This is why the ''Zoxy'' zinc-air battery system was ...
