Energy is an indispensable element for human survival. Most of the energy sources that we are currently using are nonrenewable forms of energy. These sources are limited and are exhausting at a fast rate. For non-renewable sources we have oil, coal, petroleum to list some. In this scenario of scarcity of energy, renewable form of energy provides a better and more secure option. We need to use the renewable sources to their full extent in order to reduce the burden on the non-renewable sources of energy. But these sources do have some limitations. Solar energy is not available at night, wind energy depends on the intensity of the wind speed and hydro power plant’s installation takes a toll on the environment as it damages the environment and its nearby habitat adversely. We have the technologies for the generation and implementation of these renewable sources of energy but we lack in the storage sector. The energy systems in India have an outdated storage method. We need some reliabl...

Hydro energy still remains the highest RE contributor to electricity generation globally, nevertheless, trends in solar and wind energy has shown increasing investment in RE. Though a decline in investment was observed between 2012 and 2013, yet investment in RE exceeded that of non-RE in the excess of $80 billion dollar. In 2014, investment increased by 16%. As developed countries get saturated with RE technologies, developing countries are now the focus for investment. Wistfully, path dependency problem, lack of adequate infrastructure and policy framework have been highlighted as the major barrier to RE deployment in developing countries. Also, lack of harmonised government agency for RE implementation, incentives and educational gap are the institutional and social barriers. Energy Storage (ES) is being promoted as the "game changer" with capability of smoothening the variability associated with two RE technologies, wind and solar, with the highest deployment rate. Recent developments are indicative of cost reduction for ES. This paper therefore presents a concise and holistic review of renewable energy (RE) technologies for electricity generation and assess the roles of ES in mitigating intermittency associated with their generation profile.

The purpose of any electrical network is to provide electrical power reliably wherever it is needed, avoiding any loss of load. To do this effectively, electricity networks usually consist of various different types of plants, giving a generation portfolio. Energy storage plays a very vital role in renewable energy generation and allows for supply and demand. The action of the energy storage should allow for a reduction of the overall system fuel cost while still meeting the load demand. The fuel cost supply curve is plotted to estimate energy storage in order to minimise the overall system fuel cost. We have used the historical data for the electricity demand from the website of Central Electricity Authority of India. The energy storage is optimised to minimise the overall fuel cost for the system in order to maximise profit.

Electricity generated from renewable sources, which has shown remarkable growth worldwide, can rarely provide immediate response to demand as these sources do not deliver a regular supply easily adjustable to consumption needs. Thus, the growth of this decentralized production means greater network load stability problems and requires energy storage, generally using lead batteries, as a potential solution. However, lead batteries cannot withstand high cycling rates, nor can they store large amounts of energy in a small volume. That is why other types of storage technologies are being developed and implemented. This has led to the emergence of storage as a crucial element in the management of energy from renewable sources, allowing energy to be released into the grid during peak hours when it is more valuable.
Developing technology to store electrical energy so it can be available to meet demand whenever needed would represent a major breakthrough in electricity distribution. Helping to try and meet this goal, electricity storage devices can manage the amount of power required to supply customers at times when need is greatest, which is during peak load. This paper focuses on four storage technologies that can be used as storage for wind energy conversion system. For each storage technology, the advantages and disadvantages, costs involved, the efficiency, the energy density and some major break-through in technology are discussed.
