Hydrogen and Fuel Cells - Key Technology for the Energy Revolution

The impact of global CO2 pollution can be mitigate by renewable energies, combined with a variety of more efficient use of energy. Renewable energy generators are among the fluctuating energy producers. The increasing use of renewable energies generally have an effect on the balance between the generated and consumed power. The system can get out of balance. For this reason, storage will be necessary for the future energy supply. These storages must be able to store energy of different periods: hours, days, weeks and months. For the compensation of hours and days will be used batteries, for example. For the longer periods, only gas can be use. By electrolysis, excess current can be convert to hydrogen. This generated hydrogen can be stored into the German gas network to a certain percentage. The gas thus stored will be use for the heat demand. However, it can also been converted into electricity by using gas power plants. Hydrogen can also be stored in pure form. By means of a fuel cell, it can then easily been converted back into electrical energy.

Wave and wind energy extraction in coastal environment – present, perspectives and challenges
 

Abstract:

At present, the most exciting developments foreseen in the area of the renewable energy extraction are in the nearshore and offshore areas. This is mainly due to the huge potential of these areas. From this perspective, a first objective of the proposed lecture would be to provide an up to date overview of the wave and offshore wind resources with the emphasis on the European coastal environment. Furthermore, a general survey of the technological advances related to the renewable energy extraction will be also presented together with an evaluation in various coastal areas of the efficiency of some state of the art wave and wind technologies. This will be made in terms of some indicators as: expected electric power, normalized electric power, capacity factor or capture width. Since the development of the hybrid marine energy farms, resulted by combining the wind and wave projects, might represent the most convenient way, at least for the short to medium term developments, another focus of the presentation will be the assessment of the wave energy in some places where offshore wind turbines already operate. On the other hand, the coastal impact of the marine energy farms represents a completely new challenge and a lot of work should be done in order to evaluate in a correct way the sensitivity of the shoreline wave climate to the renewable energy extraction in coastal areas. From this perspective, another aspect targeted will represent the presentation of a relevant case study related to the evaluation of the expected electrical power and of the coastal impact of a hybrid wind-wave farm operating in the Portuguese nearshore.  Finally, together with some concluding remarks, a discussion on the main challenges related to the marine energy extraction will be also employed.  This involves the LCOE reduction, some trends related to the technological advances, as the new PTO technologies, and also increasing the survival conditions.

“Role of Energy Efficient Automotive Technology and its Impact on Environmental Pollution”
 

Abstract:

The vehicular emissions have public health and environmental issues. Generally, pollutants released by engines are CO, CO2, NOx, HC, smoke and particulate matter etc. 

Today, research and development in the field of IC engines have to face a double challenge; on one hand to reduced fuel consumption, while on the other hand energy efficient with low emissions have to be fulfilled. The development of engines with its complexity requires some more effective technological tools to exploit the full potential for energy with less emission. 

Many scientists and engineers advocate for the use of alternative sources of energy to replace fossil fuels. However, the selection of an alternative source is not the end of the task. The selected alternative sources have to be exploited to its best capacity to serve the task. In case of alternative fuel, the fuel consumption can be further improved by optimizing the amount of heat generated in engines. 

The designs of IC engines being used in automotives by various manufacturers are merely suitable to changing climate conditions. The effect of atmospheric temperature on engines has an important role on vehicular emissions and environment. The detailed analysis on thermal impacts has been done for better emission quality and to environment. 

Keywords: IC engine, energy, temperature, vehicular emissions, environment.
