RENEWABLE ENERGY PROVIDERS
S&C is a Renewable Energy Service Provider. Together with our stakeholders, we strive to reduce carbon emissions by supplying renewable energy from a decentralized basis of production facilities within within our structures, in energy performances and invest in new innovative value chains for PV Solar, Biogas, Wind and Waste-to-Energy.
Electric power supply in Africa is nothing to write home about. Many Africans still live without sustainable electricity – not being connected to any grid. In many countries on the African continent, less than 20 percent of the population have access to electricity; the situation is much worse in rural areas where fewer than 5 percent are connected to the grid. With an average of 325 days of bright sunlight every year, solar power remains one of Africa’s most abundant but scarcely used resources. Fortunately, a few African countries are taking advantage of this resource but there is still more to be desired. When thinking about renewable energy it’s common to think of wind power and solar. However there is massive potential in Africa for the utilisation of renewable gas for power generation. Some naturally occurring microbes are able to break down organic material in the absence of oxygen to produce different types of biologically created gas – ‘biogas’ that consists primarily of methane and carbon dioxide. Renewable energy from biogas has the added benefit of being able to produce a consistent source of power, ‘base-load’, rather than just when the sun shines or wind blows.
Biogas is a gas that is formed by a variety of anaerobic microorganisms. These microbes feed off carbohydrates and fats, producing methane and carbon dioxides as metabolic waste products. This gas can be collected by man as a source of sustainable energy.
Biogas is considered to be a renewable fuel. Biogas creation is also called biomethanation. Biologically derived gases are produced as metabolic products of two groups of microorganisms called bacteria and Archaea. These microorganisms feed off carbohydrates, fats and proteins, a complex series of reactions including acetogenesis, methanogenesis,hydrolysis and acidogenesis then take place to produce biogas made up of carbon dioxide and methane.The organic materials required to produce biogas are available in many forms on the African continent – some uniquely so. These are biogases from dumpsites –landfill gas, biogas from human waste – sewage gas, biogas from food wastes or agricultural materials and finally naturally occurring biogas.
A waste-to-energy plant converts solid waste into electricity – an ecologically sound, cost-effective means of energy recovery. The energy plant works by burning waste at high temperatures and using the heat to make steam. The steam then drives a turbine that creates electricity.
Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth’s surface, and rotation of the earth. Mountains, water bodies, and vegetation all influence wind flow patterns of wind. Wind turbines convert the energy in wind to electricity by rotating propeller-like blades around a rotor. The rotor turns the drive shaft, which turns an electric generator. Three key factors affect the amount of energy a turbine can harness from the wind: wind speed, air density, and swept area. The African Landscape makes Africa a viable farm for electricity from wind.
