“…In TN, the use of rooftop solar installations has been suffering from the non-availability of net meters (bidirectional meters), leaving several plants in an idle state for months (Prabhakar 2019). Net meters are bidirectional meters that are used for net metering; that is, to track the difference in energy supplied to and consumed from the grid.…”

This paper explores electricity generation technology options for the sustainable energy transition of Tamil Nadu (TN). Renewable and clean energy options such as wind (onshore, offshore, small wind), solar PV, bioenergy, energy storage, and green hydrogen are selected, considering the available renewable resources in the state and the projected installation or market potential. The paper describes the current landscape of these renewable options in the state by looking at multiple aspects such as installed capacities, targets, technologies used, developments, policies, and barriers.

“…By the time "Prospects for Tapping Solar Energy on a Large Scale" and "Solar Energy Conversion and Storage Systems for the Future" were published, the advantages of storing energy as hydrogen created by electrolysis was already very clearly documented as the subject of "considerable research at OSU since 1961". These papers also discuss production and operation of a 10kW system, (Ramakumar, 1974) (Ramakumar, 1975).…”

Energy storage based upon converting electricity from water to hydrogen gas provides a solution to the problem of intermittency in renewable energy systems. These benefits are not specific to isolated solar and wind energy production but can also be derived as a complement to load and demand variations on the fully integrated electrical grid. The main components of this system are electrolytic cells, which use electricity to generate hydrogen and oxygen from water, compressed gas hydrogen and oxygen storage tanks and fuel cells, which recombine hydrogen with oxygen to generate electricity.At times of excess energy availability, electrolytic cells are used as a controllable load by which the excess energy is converted into hydrogen and oxygen gas. When there is insufficient energy to meet demands, the fuel cell is used to recombine hydrogen and oxygen into water and create electricity. Water storage and compressed gasses can be used to further tune the load. Water can be pumped from one reservoir to another to create artificial demand, and can be allowed to flow by gravitational power to create electricity on demand. Compressed gasses can similarly be managed to create load or increase generation capacity at will. These complements are key to effectively managing electrolytic cell arrays for maximum potential, but also provide for very high versatility and resilience of the system, which can allow operators to micro-manage electrical supplies and demands. This work examines the technical details of such systems and extracts some of the lessons learned from more than fifty years of related research, prototyping and implementations. Keywords-electrolysis; fuel cell; hydrogen; energy storage.I.

“…During the past half century, wide research in the area of AE has been done regarding the feasibility studies, control, modeling and simulation, and experimental work. [8][9][10][11][12][13][14][15][16][17][18][19] Electrification of the isolated and far-flung rural areas, where the grid supply is absent, has acquired much magnitude as a useful way for improving the living values. Based on the AE sources, a number of off-grid systems have been designed for this purpose.…”

The world will need greatly increased energy supply in coming years because of the rapidly increasing world population and depleting natural resources. For a long time, conventional energy sources have been utilized for power generation, but now it is of great concern that the rapid depletion of conventional sources added with their economic and environmental concerns are incompatible to address issues like growing electricity demand and environmental damages. Utilization of the alternative energy sources is compulsory to minimize the energy crisis around the world. Based on the alternative energy sources, a number of power generation systems have been designed to contribute for the management of optimized energy supply systems. The unpredictable nature of alternative energy sources is their common drawback, and they do not harness usable power for some considerable duration of time over the year. Therefore, trends are in progress to integrate two or more than two of these alternative energy systems to meet the required electricity supply in power generation operations. These systems are designated as hybrid systems and can be grid connected or off-grid depending upon their purpose and mode of fabrication. Off grid hybrid systems are popular for the electrification of the isolated and far-flung areas, where the grid supply is absent. This study mainly focuses on main 10 off grid, bi-source hybrid systems for power generation highlighting their role in energy stability. Systems' hybridization, power generation, energy flow schemes, operation schemes, and storage and backup needs have been addressed thoroughly in this study to provide a handy reference to stake holders for further work in this regime.
