The National Bio-Energy Mission (NBM) is a government initiative to promote the use of bio-energy in India. The mission aims to increase the share of bio-energy in the country’s energy mix from the current level of 2% to 10% by 2022. The NBM has identified the following sub-topics as being important for the development of … Read more
The greenhouse effect is a natural process that warms the Earth’s surface. When sunlight hits the Earth’s atmosphere, some of the energy is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the Earth’s atmosphere and surface. The greenhouse effect is essential to life on Earth. … Read more
Here is a list of subtopics without any description for Fuel Cells: Fuel cell types Fuel cell components Fuel cell operation Fuel cell applications Fuel cell advantages and disadvantages Fuel cell research and development Fuel cell future A fuel cell is an electrochemical device that converts chemical energy from a fuel into electrical energy and … Read more
Pyrolysis/Gasification subtopics: Pyrolysis Slow pyrolysis Fast pyrolysis Enzymatic pyrolysis Gasification Direct gasification Indirect gasification Coal gasification Biomass gasification Waste gasification Syngas Char Biochar Coke Tar Oil Gaseous products Liquid products Solid products Environmental impact Health impact Economic impact Future of pyrolysis/gasification Pyrolysis and gasification are two thermochemical conversion processes that can be used to convert … Read more
Here is a list of subtopics on renewable energy: Solar energy is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Wind energy is the use of wind to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power, which is then … Read more
What is a Fuel Cell? A fuel cell is an electrochemical device that converts chemical energy from a fuel into electrical energy and heat. Fuel cells are similar to batteries in that they both convert chemical energy into electrical energy, but fuel cells do not run down and need to be recharged. Instead, they can … 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
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 Renewable Energy? Renewable energy is energy that comes from natural sources or processes that are constantly replenished. These include sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy does not produce greenhouse gases or other pollutants, and it is becoming increasingly affordable as technology improves. Why is Renewable Energy Important? Renewable energy … Read more
