Sustainable Energy System

Access to modern energy services is one of the pre-requisites to improved livelihood, yet the poor, particularly in developing countries, remain tied to unhealthy and inefficient traditional fuels. Renewable energy technologies are increasingly popular energy supply alternatives to fossil-based fuels in many countries. This study presents sustainable energy system implementation options for increasing energy access in developing countries, with special emphasis on Sub-Saharan Africa. A feasibility case study and various implementation options are presented for possible deployment of these systems. Hybrid optimization of multiple energy resources software was used to simulate and validate the proposed hybrid system design and performance. The simulation results indicate that hybrid systems would be feasible options for distributed generation of electric power for remote locations and areas not connected to the electricity grid. Such a hybrid energy system, through providing modern energy services, gives promise to free-up rural communities to engage in productive activities. The opportunity to power or facilitate productive activities such as agro-processing, fabrication and services can potentially reduce poverty.

Storage Technologies

Hybrid microgrids, integrating renewable energy sources and energy storage, are key in extending energy access in the remote areas of developing countries, in a sustainably way and in providing a good quality of service. Their extensive development faces a financing gap, having a high capital expenditure (CAPEX) also due to high storage costs. In the present work, a case study of a Ugandan microgrid was used to compare various battery technologies employed on their own and in a combination with a flywheel, in terms of their durability and the overall levelized cost of energy (LCOE) of the plant. Simulations show how hybrid storage configurations result in a lower LCOE for the current load profile of the microgrid and even more so for two reference residential and industrial load scenarios, suggesting this would remain the best solution even accounting for future socio-economic development. The resulting LCOE for hybrid storage configurations is lower than the average values reported for microgrid projects and represents a promising solution to speed up the development of such electrification initiatives.

The World

Nowadays, ensuring access to energy is one of the serious challenges the world confronts. For those who live in poverty, a shortage of access to energy services desperately influences and undermines health, affects education and development. The problem of energy access for the poor countries has become even more intense because of the impacts of climate change, the global financial crisis and volatile energy prices. Then a use of another sources of energy such as wind power could be a good alternative in these countries. This paper represents a design of a vertical axis wind turbine that will produce an output power of 883 W for 9 m/s wind speed from a synchronous generator. The project involves the design and the sizing of all the components of this wind turbine. Oil barrels will be used as blades, Filippini was one of the first ones who developed a wind turbine architecture with half cylinders. Later, some modifications were introduced which leads to Thiès rotor and C-rotor. A simple design was established to facilitate its implementation and reduce its cost. This wind turbine was designed to be used in developing countries. These facts had led to think about an uncomplicated conception and use accessible and cheap equipment which could be available all over the world. Afterwards, a scaled prototype was realized to make some tests in order to examine its efficiency, some modifications were done to observe the feedback. The procedure of the design of the wind turbine was accomplished from the beginning to the end, no step has been skipped. Later, an estimation of cost was completed. The initial cost remains lower than the cost of a wind turbine in the market. Finally, this wind turbine could be constructed easily with accessible materials. An implementation of this machine in developing countries could help people in their lives. An economical model applied to an African country shows that using one turbine could save about 1400 € per year.
