Turning to good account the agricultural potential by encouraging alternative crops of technical plants, such as rape, aiming to provide an alternative energy source of fuel for tractors and self-propelled agricultural machines, represents a current energy expectation with extensive perspectives of development in the field cropping from Romania. During the last years the cropping of plants with a high energy potential: rape, soy beans, sunflower, sugar sorghum etc. on larger and larger surfaces has known an outstanding proportion, most of all that after EU negotiations and the implementation of the Community acquits that refers to arable crops (cereals, oil-bearing plants, protein crops, etc.) each EU-member country received a quota from the overall surface that is lower than the existing one, and thus important surfaces remained that may be used, as such, for the cropping of plants with a high energy potential aiming to assure the required energy for their own consumption in farms, micro-farms etc. (alternative energy sources). In opposition to conventional fuels, “biodiesel” has a reduced content of sulphur, its presence in the air generating acid rains. “Biodiesel” does not contain aromatic matters either, such as benzene. During “biodiesel” burning carbon dioxide is generated, however, no toxic pollutants.

Fact Finding

The DESERTEC project, a European Union (EU) initiative to harness solar energy by means of Concentrated Solar Power (CSP) from Africa for use in Europe, shows the enormous potential that exists in alternative energy sources for the sub-region once there is political will. The Trans-Mediterranean Renewable Energy Corporation (TREC), a network of scientists and politicians who have taken it upon themselves to solve Europe’s energy problem using sun from Africa, conducted three studies which evaluated the potential of renewable energy resources in the Middle East and North Africa (MENA), the expected needs for water and power in EU-MENA between now and 2050 and issues relating to the construction of an electricity transmission grid connecting the EU and MENA (EU-MENA-Connection), with a formula to turn the North African desert sun into electricity and transport same to Europe. This paper harnesses the TREC fact-finding studies in order to estimate how much the same ideas can be applied in many other parts of the world, Nigeria in particular. Investigation reveals that this association exists with huge potentials for an energy-starved country like Nigeria in harnessing her abundant hot sun in the north, which could go a long way in meeting the energy needs in that part of the country and beyond. Other benefits include unlimited supplies of clean electricity, agricultural gains, and creation of new industries, new jobs and new sources of income.

The direct methanol fuel cell (DMFC) is among the most promising alternative energy sources for the near future owing to its advantages of simple construction, compact design, high energy density, and relatively high energy-conversion efficiency. Typically, the electrodes in DMFC is comprised of a Pt-based catalysts supported on great potential of carbon materials such as multi-walled carbon nanotubes (MWCNTs), carbon black (CB), graphene, etc. It is desired to develop an electrode with high surface area, good electrical conductivity and suitable porosity to allow good reactant flux and high stability in the fuel cell environment. This chapter will provide recent advances in Pt-based binary and ternary electrocatalysts on carbon supports for high-performance anodes in DMFC. Through studying the effects of composition-, support-, and shape dependent electrocatalysts, further fundamental understanding and mechanism in the development of anode catalysts for DMFC will be provided in details.

In this article, I state that the IEA predicts that global energy usage will continue to increase over the next twenty years by as much as 45%, driven largely by the emerging economies of North and South Asia. This assessment is most pertinent in relation to oil, which currently accounts for the largest share of global energy use due to the oil dependence of the transport sector. I point out that the major supplier of oil to the global market, West Asia’s Arabian/Persian Gulf, is also experiencing relatively high energy consumption growth, and the Gulf states have thus found themselves confronted with the paradox of needing to develop alternative energy sources for their own domestic use while requiring the world’s traditional dependence on oil to continue so that they can maintain their export revenues. To the extent that alternative energy sources are developed, the commerciality of the oil reserves of supplier states is made less secure. The article explains how the growth in oil consumption has also raised questions about the medium to long-term security of supply for Asian oil-importing states which have invested substantially in supply contracts and in acquiring equity in upstream production in the Gulf. I examine both the potential threats and benefits that might arise from this emerging trans-Asian oil nexus including the increasing dependence by Asian oil importers on supplies from an inherently unstable region, and the pursuit of alternate technologies by suppliers and consumers.

Given Ukraine's high dependence on imported energy, primarily natural gas, and the availability of great biomass potential, it has been proven that bioenergy is one of the strategic directions of the sector's development in renewable energy sources. It is determined that the pace of bioenergy development in Ukraine still lags significantly behind European ones. It is established, that in the developed countries of the world use of biomass as a source of energy continues to play an important role because of a significant increase in prices for oil and gas, as well as the growing demand for protection of the environment. Therefore, the introduction of modern technologies for continuous energy production from biomass is an important condition for the solution of problems of supply of energy and prevent degradation of the environment. The possibility of using biofuels in the Kyiv region is proved, the investment attractiveness of this region as a source of thermal energy is revealed. The methodical approach to estimating the theoretical potential of waste due to the use of alternative energy sources is substantiated. The theoretical energy potential of the biomass of by-products of agricultural crops of private enterprise "Sosnova" was assessed, which made it possible to determine the prospects of an agricultural enterprise in the energy supply of the Kyiv region at the expense of biofuels. According to the generally accepted method, the theoretical energy potential of straw and vegetable waste of private enterprise "Sosnova" was calculated, which in the market turnover in 2019 amounted to 8392 tons of oil equivalent. It was determined that the predominant type of biomass in the studied enterprise were corn stalks and wheat straw. On the example of the object of the school, which is located near the investigated enterprise, the calculation of savings on heating by replacing the traditional type of fuel (natural gas) with biofuel. The calculations show that due to biofuels the company can provide 28% of the school's need for the heating season. The savings will be - 60.6 thousand UAH and its use allow you to save about 43% of fuel annually.

Near Future

The global economy lives a period of great apprehension regarding energy issues for the near future. The developed countries continue to have a steady growth and the emerging countries increase their rates of economic growth, which causes a continuing increase in global energy demand. In that context, RETERM calls the attention of the readers to the growing need for the search of alternative energy sources to the current oil based global economy. This effort certainly involves focus and work of the energy related scientific community, field in which Thermal Engineering is part of. There are several alternatives currently under consideration. The Department of Energy of the United States of America is currently seriously focused on research and development of alternative energy sources, mainly aiming the independence of external suppliers, such as nuclear energy and the hydrogen economy. Therefore, it is vital to any nation the allocation of financial resources to the development and technological control of new processes that lead to self-sufficiency in energy generation for internal consumption and economic growth. The fuel cell systems will be of critical importance in the possible hydrogen economy scenery for the near future, and they are at the forefront of the emerging technologies for electric power generation for stationary, mobile and portable applications. The high energy conversion efficiencies, extremely low onsite environmental pollution and noise are among their major advantages in comparison to other systems. However, there are major technological and economic hurdles to be overcome prior to their large scale practical implementation. Similarly to nuclear technology, in fuel cell technology it is observed that each research group develops its own know-how independently and with little exchange of information.In this fifth number, we continue to publish the best articles written in English language, presented at the 9th Brazilian Congress of Thermal Engineering and Sciences, ENCIT 2002, held in Caxambu, MG, from October 15th to 18th, 2002, that were selected by the Associate Technical Editors of RETERM, according to the scientific criteria of the journal. The idea is to increase the industrial and scientific impact of the research results presented in the Congress. Additional articles that have been submitted and reviewed in the regular RETERM publication process are also included in the current issue.

Abstract Currently, alternative energy sources are attracting attention owing to environmental pollution and the depletion of fossil fuels. Lithium-ion batteries have a light weight, high energy density, high power density, and long cycle life, making them attractive alternative energy sources. Numerous studies have been conducted on high-performance batteries. However, most studies have focused on improving active material characteristics. Thus, there is a lack of research on battery performance enhancement through the improvement of the battery manufacturing process. In this study, we performed electrode structuring using a nanosecond laser in the power range of 1 W to 19 W (2 W intervals). The geometric changes after laser structuring were observed using a scanning electron microscope, and the electrode geometries were classified and measured in terms of ablation width and depth. The aspect ratio, removal amount, and removal rate of the active material were analyzed after laser structuring. A maximum aspect ratio of 0.77 was achieved. Additionally, the removal amount and removal rate of the active material increased with the increase in laser power. Therefore, we concluded that electrode geometry can be controlled using a nanosecond laser.

AbstractDespite enormous challenges in accessing sustainable energy supplies and advanced energy technologies, Ethiopia has one of the world's fastest growing economies. The development of renewable energy technology and the building of a green legacy in the country are being prioritized. The total installed capacity for electricity generation in Ethiopia is 4324.3 MW as on October, 2018. Renewable energy accounts for 96.5% of total generation; however, despite the county's enormous biomass energy potential, only 0.58% of power is generated using biomass. Ethiopia has surplus woody biomass, crop residue and animal dung resources which comprise about 141.8 million metric tons of biomass availability per year. At present the exploited potential is about 71.9 million metric tons per year. This review paper provides an in-depth assessment of Ethiopia's biomass energy availability, potential, challenges, and prospects. The findings show that, despite Ethiopia's vast biomass resource potential, the current use of modern energy from biomass is still limited. As a result, this study supports the use of biomass-based alternative energy sources without having a negative impact on the socioeconomic system or jeopardizing food security or the environment. This finding also shows the challenges, opportunities and possible solutions to tackle the problem to expand alternative energy sources. The most effective techniques for producing and utilizing alternate energy sources were also explored. Moreover, some perspectives are given based on the challenges of using efficient energy production and sustainable uses of biomass energy in Ethiopia as it could be also implemented in other developing countries. We believe that the information in this review will shed light on the current and future prospects of biomass energy deployment in Ethiopia.
