AbstractA new industrial revolution is on the verge in the energy domain considering the knowledge and skills acquired through the development of new energy technologies. Shale gas processing, unconventional oil exploitation, new exploring/drilling methods, mature renewable energy or in progress, all generated a wealth of knowledge in new technology. Therefore, this paper aims to analyse the positive and negative aspects of energy solutions, and to reveal the way to a world where a valid sustainable development, based on safe and rational premises, is actually considered. The paper also introduces suggestions for the energy system, which has a crucial importance in coping with the resource management of the future, where the economic, social, and environmental/climate needs of the post-crisis world should be suitably considered.

The decisions taken at the 7th session of the Conference of the Parties to the UNFCCC make it likely that sufficient Parties will proceed with ratification of the Kyoto Protocol to result in its entry into force before the Johannesburg summit in 2002. Can the European Community fulfil the obligations of the Kyoto Protocol? The answer is yes and easily, if it follows the wise-man approach, taking advantage of the flexible mechanisms, using the option to absorb CO2 emissions by proper “land-use-change”, exploiting the greenhouse gas reduction potential outside the energy sector and implementing some of the current proposals in the area of energy and transport policy. Quantitative analysis lead to the result that there is no need to develop new measures to meet the obligations of the Kyoto Protocol. The coming years can be used to facilitate the transition to a new energy system and to start exploring policies beyond 2012.

El actual sistema energético mundial se caracteriza por una alta dependencia de los combustibles fósiles, un paradigma que empieza a encontrar dificultades en tanto se agotan las reservas existentes y aumentan los costos ecológicos. Así, la incorporación de energías renovables, su generación en forma distribuida y el crecimiento del parque automotor eléctrico, se presentan como la triada más prometedora en la conformación de un nuevo paradigma más eficiente y sustentable. Este artículo se centra en la importancia que adquieren los acumuladores energéticos ante este panorama, principalmente por su rol en la estabilización de las redes y posibilitar el autoconsumo y la propulsión eléctrica. Identifica en las baterías de ion-litio un abanico de posibilidades para Sudamérica, que posee las reservas más importantes de litio en el mundo, incorporando la idea del desarrollo dentro del nuevo patrón energético y en un mercado actual y potencial de grandes dimensiones. Abstract The current global energy system is characterized by a high dependence on fossil fuels, a paradigm that begins to encounter difficulties as existing reserves are depleted and ecological costs increase. Thus, the incorporation of renewable energies, their generation in a distributed form and the growth of the electric motor park, are presented as the most promising triad in the conformation of a new, more efficient and sustainable paradigm. This article focuses on the importance that energy accumulators acquire in this scenario, mainly due to their role in stabilizing networks and enabling self-consumption and electric propulsion. It identifies lithium-ion batteries with a wide range of possibilities for South America, which has the most important reserves of lithium in the world, incorporating the idea of ​​development within the new energy pattern and in a current and potential market of large dimensions.

The Given

This chapter returns to the overarching questions of this book, namely, how can national energy transitions be explained, to what extent do patterns of change align and differ in the transitions of this study, and how does policy play a role, particularly with innovations that emerged amid the transitions. To broadly answer, the four cases are comparatively examined here. The conceptual tools from Chapter 3 are also elaborated based on the findings. Implications of the results are discussed, and will serve as a basis for further discussion in Chapter 9 on how to think about energy transitions as a planner, decision-maker, and researcher. Among the more significant findings are the following. Greater energy substitution (in relative terms) occurred initially within the countries that extended or repurposed existing energy systems versus the country (i.e., Denmark) that developed a new energy system from a nearly non-existent one. Cost improvements were evident in all cases; however, a number of caveats are worth noting. Among the energy technologies and their services that were studied, only Icelandic geothermal-based heating was competitive in its home market in the 1970s; nonetheless, the remaining energy technologies that were studied later became cost competitive. As the national industries of this book became globally recognized, increases in the quality of living within the given countries also occurred, as gauged by the Human Development Index (HDI). With respect to timescales, substantial energy transitions were evident in all cases within a period of 15 years or less. In terms of technology complexity, this attribute was not a confounding barrier to change. Finally, government was instrumental to change, but not always the driver. There are countless ways to compare national energy transitions. This section illustrates ways of doing so, first by describing broadly observed, socio-technical patterns with the tool typologies outlined in Chapter 3. A discussion of tool refinement follows. The section then turns to more systematically assess key, qualitative and quantitative dimensions of the four transition cases.

This study deals with new internal combustion turbine power systems in which a steam-gas mixture is the working medium. Heat is delivered to the system by injecting gaseous fuel and steam into the combustion chamber. Unlike in STIG systems, the fluid expansion in the turbine is much deeper (much below the atmospheric pressure) and the exhaust gas is cooled in a heat exchanger-condenser in such a manner that a significant amount of water can be recovered. The non-condensing gases (CO2 + N2 + rest of O2) from the exhaust fluid are compressed, after additional cooling, and discharged into the atmosphere. If a cheap or waste fuel is available, the steam to be injected into the combustor can be produced in a waste fuel-burning boiler or in conventional coal boiler. In this case the heat exchanger between the turbine and condenser can deliver significant amounts of useful (process or district) heat or / and preheated feedwater for the boiler. The efficiency analysis of this new energy system shows a growth by more than 10 percent points in comparison with the conventional STIG engine, at the same pressure ratio and turbine inlet temperature.
