SEF energy company manages energy generation from renewable sources at a local level. We are a major operator in the field of energy generation from renewable sources mainly from water, the Sun, wind and the Earth's heat, meeting the energy consumption of many families and avoiding million tonnes of CO2 emissions per year.
We are committed to contributing to sustainable development. We believe that renewable sources play a central role in promoting the competitiveness of production systems and ensure secure energy supplies. Indeed, widespread electricity generation from water, the Sun, wind and the Earth's heat help improve a country's energy independence, while also protecting the environment.
SEF energy aims to grow by substantially increasing its partnerships with the world's most experienced renewable power equipment manufacturers to drive the evolution of products and technologies in Africa while building on SEF's expertise in this sector. We also work for families and companies in order to achieve energy self-production, -consumption and -management.
We brag about the good stuff that pays its way and improves the way we power our future. We are supporting our efforts to advance the best of what it means to be SEF, furthering our mission to empower consumers and "Reform Your Energy… Transform the World"
Marine current generators use marine or tidal currents to generate electricity that is both renewable and predictable.
Photovoltaic (PV) employs solar panels, each comprising a number of solar cells, which generate electrical power. The first step is the photoelectric effect followed by an electrochemical process where crystallized atoms, ionized in a series, generate an electric current. PV Installations may be ground-mounted, rooftop mounted or wall mounted.
When photons (the particles that make up the sun's rays) meet the surface of a cell, they transmit their energy to the cell's electrons causing them to move and create a direct electric current. This current is then converted into alternating current by a converter so that it can be fed into the distribution grid.The photovoltaic energy can be harnessed industrially at a solar farm or individually by homeowners or at sites isolated from the rest of the network.
Geothermal heat stored in the earth's subterranean layers can be used to produce thermal or electrical energy. Two types of geothermal energy can be produced, depending on the temperature of the heat extracted.
Low-temperature geothermal Energy (below 150 °C): the energy captured is useful for air conditioning or heating systems in buildings. Geothermal probes capture energy which is used in heat pumps via heat exchangers.
Medium and high temperature geothermal energy (above 150° C): this energy is strong enough to produce electricity or to use directly as heat. Two types of technology are used: either the use of steam reservoirs or hot water
Wind power is currently enjoying spectacular growth around the world. This form of renewable energy is one of SEF energy's main focus for growth.
Tidal energy seeks to harness the differential between low and high tides. There are many advantages in using tides to generate electricity: tides are a perfectly predicable phenomenon (unique for a renewable energy source), they are inexhaustible and carbon-free, and they have low environmental impact.\
The principle involves building a barrage to create an artificial reservoir and so a differential in water levels to drive the turbines and alternators that will generate electricity. A tidal power plant uses the rising and falling movement of tides to create the level differential needed to produce energy.
Biomass is the world's second largest source of renewable energy
The combustion of organic plant or animal matter has a calorific value that can be harnessed to produce heat or electricity. This provides a solution to the problem of how to manage municipal and farm waste.
The word "biomass" encompasses a very broad range of materials: wood, wood processing industry waste, farm waste (straw, liquid manure, etc.), the fermentable fraction of household waste and food & beverage industry waste, landfill biogas, and the by-products from anaerobic digestion (liquor, treatment sludge, solid residue, etc.)
This organic matter is recovered through thermal processes (pyrolysis, gasification and direct combustion) or biochemical processes (anaerobic digestion) to produce energy. Municipal and farm waste can thus be used as infeed for thermal power plants or electricity generators.
Two categories of biomass are used in this instance:
• ligneous biomass: wood, straw or bagasse (sugarcane fiber) used in thermal power plants
• fermentable biomass: liquid manure, residual liquor and waste. This biomass is first converted into biogas by microorganisms, which is then burned in specifically designed electricity generators.
This Environmental Management Plan (EMP) has been prepared for SEF Energy Co. Ltd. for the purpose of providing a stand-alone plan for managing the potential environmental and social impacts of upstream oil and gas operation activities within Ghana. The Environmental Management Plan is based on the assessments and findings of the Environmental Impact Statement (EIS).
