Sudan enjoys abundant solar, wind, hydro, and biomass resources. Like many tropical countries, Sudan has ample biomass resources that can be efficiently exploited in a manner that is both profitable and sustainable. Fuel-wood farming offers cost-effective and environmentally friendly energy solutions for Sudan, with the added benefit of providing sustainable livelihoods in rural areas. Biogas from biomass appears to have potential as an alternative energy in Sudan, which is potentially rich in biomass resources. This is an overview of some salient points and perspectives of biomass technology in Sudan. The current literature is reviewed regarding the ecological, social, cultural and economic impacts of biomass technology. This article provides an overview of biomass energy activities and highlights future plans concerning optimum technical and economical utilization of biomass energy available in Sudan. © 2011 by Walter de Gruyter.

The move towards a low-carbon world, driven partly by climate science and partly by the business opportunities it offers, will need the promotion of environmentally friendly alternatives if an acceptable stabilisation level of atmospheric carbon dioxide is to be achieved. This requires the harnessing and use of natural resources that produce no air pollution or greenhouse gases (GHGs) and provides comfortable coexistence of humans, livestock, and plants. Ground source heat pump systems (GSHPs) are receiving increasing interest because of their potential to reduce primary energy consumption and thus reduce emissions of GHGs. The main objective of the research is to stimulate the uptake of the GSHPs. This paper describes the details of a prototype direct expansion GSHP test rig and details of the construction and installation of the heat pump, heat exchanger, heat injection fan and water supply system. It also presents a discussion of the experimental tests currently being carried out. Source

Sudan is an agricultural country with fertile soil and ample water resources, as well as livestock and forestry resources, and agricultural residues. Energy is one of the key factors in the development of Sudan's national economy. We present an overview of the energy situation in Sudan, with reference to its end uses and its regional distribution. We separate energy sources into two main types: conventional energy (biomass, petroleum products, and electricity) and non-conventional energy (solar power, wind energy, hydro-electric, etc.). Sudan has a relatively high abundance of sunshine and solar radiation, and has moderate biomass, hydro-electric and wind energy resources. Exploiting the available new and renewable energy sources to provide part of the local energy demand, as alternatives to conventional fossil energy, has become a major issue in Sudan's strategic planning of future energy policies. Sudan presents an important case study with respect to renewable energy, as it has a long history of meeting its energy needs by use of renewable sources; Sudan's portfolio is broad and diverse, due in part to the country's wide range of climates and landscapes. Like many African frontrunners in the utilisation of renewable energy, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios in the new century emphasize the importance of exploiting the untapped potential of renewable resources. Sudan's rural areas in particular, can benefit from this transition. The increased availability of reliable and efficient energy services will stimulate the development of new alternatives. We conclude that using renewable, environmentally friendly energy must be encouraged, promoted, implemented, and demonstrated by full-scale energy plants or collection devices, in particular for use in remote rural areas.

The imminent exhaustion of fossil energy resources and the increasing demand for energy were the motives for those reasonable in Sudan to put into practice an energy policy based on rational use of energy; and on exploitation of new, and renewable energy sources. After 1980, as the supply of conventional energy has not been able to follow the tremendous increase of the production demand in rural areas of Sudan, a renewed interest for the application of wind energy has shown in many places. Therefore, the Sudanese government began to pay more attention to wind energy utilisation in rural areas. Because the wind energy resource in many rural areas is sufficient for attractive application of wind pumps, and as fuel is insufficient, the wind pumps will be spread on a rather large scale in the near future. Wind is a form of renewable energy, which is always in a non-steady state due to the wide temporal and spatial variations of wind velocity. A number of years worth of data concerning wind speed in Sudan have been compiled, evaluated and presented in this article. The need for the provision of new data stations in order to enable a complete and reliable assessment of the overall wind power potential of the country is identified and specific locations suggested. This paper presents the background and ideas of the development of the concept as well as the main results, and experience gained during ongoing project up to now. In Sudan, various designs of wind machines for water pumping have been developed and some designs are presently manufactured commercially. Results suggest that wind power would be more profitably used for local and small-scale applications especially for remote rural areas. It is concluded that Sudan is blessed with abundant wind energy. Source
