The present energy crisis and pollution problems are the incentives for the search of alternative energies from renewable resources or using the existing resources with less environmental impacts. This course will pave the way to manipulate the existing energy technologies, to search for alternative fuels and to keep the environment clean for our needs. The following modules have been majorly planned as a part of this course. Lab visits and pedagogy sessions are also included in this course.
Solar Energy: Solar energy is suitable for heating and electricity generation using solar thermal/electric power plants. These solar thermal/electric power plants generate electricity by concentrating/non-concentrating solar energy to heat a fluid and produce steam that is then used to power a generator. The disintegrated nature of solar power makes it a practical and viable energy source in remote areas located far from the electricity grid. Also, this is crucial for agri-business in farms for running irrigation, greenhouses, and crop and hay dryers, making agriculture risk-free. However, the challenge in solar energy harvesting and utilization is far from being solved and there needs to be more access to its technology and more progress needs to be made regarding integrating solar energy into enduse applications in buildings, transport andindustry.
Biomass: Biomass is one of the foremost vital essential, renewable energy resources for an anticipated renewable and sustainable energy market. There's an urgent requirement to develop most competent technologies to convert lignocellulosic and municipal solid waste (MSW) biomass resources into maximum useful energy based on thermodynamic feasibility and system technology, as well as from an environmental perspective. This course will discuss the resources necessary to overcome obstacles and challenges in biofuel research.
Gas & Coal Gasification: This technique helps in burning all the mass without leaving any carbonaceous residue. Although there was no worry of the carbon footprint, now the world is horrified to see any increase in it. The carbon capture technology, underground coal gasification, natural gas production and transportation come under this module. Study on this will help the participants to enlighten the ways of carbon foot print reduction.
Hydrogen Energy and Fuel Cells: Many of our fuels, for example, gasoline, natural gas, methanol, and propane contains hydrogen. Hydrogen can be isolated from hydrocarbons through the application of heat called as reforming. As of now, most hydrogen is made through this route from natural gas. An electrical can also be utilized to isolate oxygen and hydrogen from water. This procedure is known as electrolysis. Some microorganisms (algae and bacteria), utilizing sunlight as their energy source, even give off hydrogen under specific conditions. An engine that burns pure hydrogen creates no pollution. Hydrogen fuel cells combines hydrogen and oxygen to produce electricity and a clean by product – pure water. Fuel cells are a promising technology for use as a source of heat and electricity for buildings, and as an electrical power source for electric motors propelling vehicles. Fuel cells operate best on pure hydrogen and other fuels like natural gas, methanol. The challenges and recent developments in these technologies will be addressed in this course.
