Due to the lack of fossil fuels and its products quantities,
obtaining difficulties, and its global and local high price. It has
become necessary to look for other means and methods of
providing electrical energy far from fossil resources or suppo
rt
the existing ones.
The study is focused on renewable energy sources, especially
solar energy (both thermal and photovoltaic), wind energy as
well as biomass which are sufficiently available in the Syrian
Arab Republic.
Utilizing the renewable energy sources is the main focus of
this study, in which the investment in the field of photovoltaic
energy and economic efficiency will be reviewed and
compared to generating electricity using diesel generators.
The Research aimed to use the technology of the fermentation to produce the biogas from the cow manure. The digester has benn carried according to the Indian model. The digester consit of one cylinerical tank with 9.42m3 volume (height 3m, diameter 2
m) and gastank with 6m3 (height 1m) and inlet pipe and outlet pipe. The study showed the following:
The accumulated production of biogas was through the 30 days retention time 48m3. The heighest production was in the thirteenth day with 4.5m3. The farm became after the use of digester clean and with little insect and smell.
With use 1m3 of biogas could we use one cooker for 2.5 hour and with the same quantity could we use one inner combustion diesel motor (90% biogas and 10% diesel) for half an hour.
3/4m3 from digester volume is enough for one cow with 12 kg manure daily. So we can design the suitable digester for any farm.
The power supply in remote areas has been usually provided by thermal power plants, usually diesel
generators. Recently the use of renewable resources to generate electricity and protect the environment
increased rapidly. Hybrid power systems may c
onstitute the most economical solution in many
applications in the near future, especially for electrification remote area.
Hybrid systems by definition contain a two sources or more of power generation (or storing) to supply
electricity to the loads. These sources may be pure traditional, traditional and renewable, or may be
renewable only.
This paper describes a case study for a remote area. It shows importance of using the hybrid system to
electrify a remote area. The suggested hybrid system consists of wind turbine, PV, traditional generator,
and batteries to supply a load (72 kWh/d). A real wind data related to Alsukhna near Homs is used. We
perform a technical and economical analysis using Homer to determine the optimal design of a hybrid
System for a Reliable Load Supply in Remote Area with least cost.
The integration of various renewable energy sources as well as the liberalization of
electricity markets are established facts in modern electrical power systems. The increased
share of renewable sources within power systems intensifies the supply
variability and
intermittency. Therefore, energy storage is deemed as one of the solutions for stabilizing
the supply of electricity to maintain generation-demand balance and to guarantee
uninterrupted supply of energy to users. In the context of sustainable development and
energy resources depletion, the question of the growth of renewable energy electricity
production is highly linked to the ability to propose new and adapted energy storage
solutions. Recent advancements in hydrogen technologies and renewable energy
applications show promise for economical near to conversion to a hydrogen-based
economy. As the use of hydrogen for the electric utility and transportation sectors. This
paper briefly discusses provides a historical perspective for hydrogen production and the
role of hydrogen as an energy carrier, discusses hydrogen economy, the process of
electrolysis for hydrogen production (especially from solar and wind technologies).
A comprehensive techno/socio/economic study of long term hydrogen based
storage systems in electrical networks is addressed. the excess produced hydrogen during
high generation periods or low demand can be sold either directly to the grid owners or as
filled hydrogen bottles. The affordable use of Hydrogen-based technologies for long term
electricity storage is verified. The results indicate that ample resources exist to produce
Hydrogen from wind and solar power. However, hydrogen prices are highly dependent on
electricity prices.
Building a photovoltaic system is the process of designing,
selecting and calculating the ratings of the equipment’s employed in
the system. This process depends on a variety of factors such as
geographical location, solar irradiation, and load re
quirements. this
paper presents a practical way to calculate the elements and
components of the Stand-Alone PV energy system, And procedure
an economic analysis for the system, will allow GUI designed by
MATLAB knowledge of these components depending on the
efficiency of the Inverter, power solar panels and capacity of
batteries in local market, taking into account the climatic factors and
hours of solar radiation in the system installation area, as well as the
cost of the system and the payback time.
The research problem is neglecting urban policies and construction
systems to use renewable energy within urban fabric, in particular
solar energy. And it aims to study the relationship between urban
morphology and solar energy potential and its r
ole in the
establishment of more suitable cities in terms of energy, and thus
guide the planning policies to increase utilization of solar energy
within cities.
