What is Cogeneration? Cogeneration is the simultaneous production of two useful forms of energy, such as electricity and heat, from a single fuel source. This is in contrast to conventional power plants, which only produce electricity. Cogeneration can be used in a variety of applications, including hospitals, hotels, schools, and manufacturing facilities. How does Cogeneration … Read more
Waste to Energy Introduction Waste to energy (WTE) is a process that converts waste materials into energy. This can be done through a variety of methods, including incineration, gasification, and pyrolysis. WTE can be a valuable tool for managing waste and reducing greenhouse gas emissions. How does waste to energy work? There are a number … Read more
Combustion/Incineration Combustion is a chemical reaction that occurs between a fuel and an oxidizer, releasing heat and light. The most common type of combustion is the burning of fossil fuels, such as coal, oil, and natural gas. Combustion is also used in many industrial processes, such as the production of electricity and the manufacture of … Read more
Pyrolysis/Gasification Pyrolysis and gasification are two thermochemical conversion processes that are used to convert organic materials into a variety of products, including fuels, chemicals, and biochar. Pyrolysis is a thermal decomposition process that occurs in the absence of oxygen, while gasification is a partial oxidation process that occurs in the presence of a limited amount … Read more
Tidal energy is a form of hydropower that extracts energy from the rise and fall of tides. It is a renewable energy source that has the potential to provide a significant amount of electricity. Tidal energy is currently being harnessed in a number of countries around the world, and there is potential for further development … Read more
Biomass Biomass is a renewable energy source that comes from plants and other organic materials. It can be used to generate electricity, heat, and transportation fuels. Biomass is a carbon-neutral fuel, which means that it does not release any more carbon dioxide into the atmosphere than was absorbed by the plants when they were growing. … Read more
Anaerobic digestion is a process that converts organic waste into biogas and digestate. Biogas is a renewable energy source that can be used to generate electricity, heat, or fuel vehicles. Digestate is a nutrient-rich soil amendment that can be used to improve crop yields. Anaerobic digestion is a natural process that occurs in the absence … Read more
What is a pumped storage hydro power plant? A pumped storage hydro power plant is a type of hydroelectric power plant that uses two reservoirs at different elevations to store water. During periods of low demand for electricity, water is pumped from the lower reservoir to the upper reservoir. When electricity demand is high, the … Read more
Ocean Thermal Energy Conversion (OTEC) is a renewable energy technology that uses the temperature difference between the warm surface water and the cold deep water of the ocean to generate electricity. OTEC is a promising source of clean, sustainable energy that has the potential to provide a significant portion of the world’s electricity needs. OTEC … Read more
Wave energy is a form of renewable energy that can be harnessed from the waves of the ocean. It is a clean and sustainable source of energy that has the potential to provide a significant amount of power to the world. Wave energy is generated by the rise and fall of the waves. As the … Read more
