Energetic Characterization

Saccharum spontaneum, known locally as “Paja Canalera”, is a non-native herbaceous species of Panamanian flora, it is invasive and can spread rapidly, even in critical environmental conditions. In the dry season, it is the object of fires of plant mass affecting other species of flora, fauna and communities. This study focuses on assessing the use of the species as a biomasic material for energy production through the gasification technique. Samples of the material present in the Panama Canal Hydrographic Basin (CHCP) were conducted, where there are approximately 6,932 hectares covered by that species. A thermophysical and energetic characterization of the species was carried out, and the use of said plant species is considered as a renewable energy resource with the potential to be converted into gaseous fuel (syngas) by means of the gasification technique and its subsequent generation of electrical energy. Based on the available Biomass, results indicate an energy potential of 536.5 GWh. Tests of various treatments were carried out based on the physical properties of the biomass and tested with various volumetric air flows in order to find the most efficient form of gasification of S. spontaneum, based on the chemical composition of the resulting gas.

Renewable Natural Resource

Bamboo is a grassy plant that grows rapidly, is also a renewable natural resource and with a high yield. There are many applications and uses of bamboo, which led to its planting around the world. Among the industries in which bamboo has by now experienced extensive exploitation, we can remember the textile, construction, furniture ; even food, pharmaceutical or cosmetic industries. Biomass is the plant material that is used as a renewable energy resource. This is achieved others by cultivating plants specially used for energy production or by using resistors from small industrial sectors. The current paper highlights the potential for the recovery of bamboo as biomass, both in terms of the fact that bamboo is a plant that is believed to be an inexhaustible resource, but also for the wide amount of rest from its multiple uses.

Electrical Energy Production

In recent years, decreasing reserves and environmental problems related with fossil fuels have increased the demand for clean and renewable energy sources, as with all over the world and also in Turkey. Wind energy is the one of the most rapidly growing among the renewable energy sources in terms of technological and utilization. Turkey is one of the rich countries in Europe in respect to wind energy potential. Productive and effective use of this potential is very important for Turkey that is depended on foreign countries especially in respect to fossil energy sources. Wind speed values are the most important data in calculation of electrical energy from wind turbines. In this study, latest developments and energy-power equations related to wind turbines are investigated. Using of the data obtained from the wind measurement station installed in Sakarya-Esentepe region, annual electrical energy production of an example wind plant is predicted.

The present work aims to determine the energy potential of biomass in the province of Manabí, having as main actors the residues of cocoa, dry corn, bananas, and African palm, these being the products with the greatest abundance within the province since during Its production is constant throughout the year and this allows it to be used as a base for energy production. The increase in greenhouse gases in the production of consumable electrical energy has led to a significant advance in the development of biologically friendly alternatives. Among these alternatives, one of the options for immediate implementation is obtaining energy through the combustion of conventionally wasted waste, also known as biomass.

For energy production and also for the glass industry, finding new refractory alloys which could permit to increase the process temperatures to 1200°C or more is a permanent challenge. Chromium base alloys can be good candidates, considering the melting point of Cr itself, and also its low corrosion rate in molten glass. Two families of alloys have been studied for this purpose, Cr-Mo-W and Cr-Ta-X alloys (X= Mo, Si..). A finer selection of compositions has been done, to optimize their chemical and mechanical properties. Kinetics of HT oxidation by air, of corrosion by molten glass and also creep properties of several alloys have been measured up to 1250°C. The results obtained with the best alloys (Cr-Ta base) give positive indications as regards the possibility of their industrial use.

Wind Energy Potential

The significant offshore wind energy potential of Oregon faces several challenges, including a power grid which was not developed for the purpose of transmitting energy from the ocean. The grid impacts of the energy resource are considered through the lenses of (i) resource complementarity with Variable Renewable Energy resources; (ii) correlations with load profiles from the four balancing authorities with territory in Oregon; and (iii) spatial value to regional and coastal grids as represented through a production cost model of the Western Interconnection. The capacity implications of the interactions between offshore wind and the historical east-to-west power flows of the region are discussed. The existing system is shown to accommodate more than two gigawatts of offshore wind interconnections with minimal curtailment. Through three gigawatts of interconnection, transmission flows indicate a reduction of coastal and statewide energy imports as well as minimal statewide energy exports.

Management Issues

The Soultz-Sous-Forêts geothermal site (France) operates three deep wells for electricity production. During operation, scales precipitate within the surface installation as (Ba, Sr) sulfate and (Pb, As, Sb) sulfide types. Scales have an impact on lowering energy production and inducing specific waste management issues. Thus scaling needs to be reduced for which a thorough characterization of the scales has to be performed. The geothermal brine is produced at 160 °C and reinjected at 70 °C during normal operation. In the frame of the H2020 MEET project, a small heat exchanger was tested in order to allow higher energy production, by reinjecting the geothermal fluid at 40 °C. Samples of scales were analyzed by XRD and SEM-EDS, highlighting that mostly galena precipitates and shows various crystal shapes. These shapes can be related to the turbulence of the flow and the speed of crystal growth. Where the flow is turbulent (entrance, water box, exit), crystals grow quickly and mainly show dendritic shape. In the tubes, where the flow is laminar, crystals grow more slowly and some of them are characterized by well-developed faces leading to cubes and derived shapes. The major consequence of the temperature decrease is the increased scaling phenomenon.
