Flywheels are a form of kinetic energy storage that can provide both energy and high power capabilities. They use rotating composite materials to store energy, offering advantages over other storage like batteries including higher efficiency, longer lifetime, and more flexible charge/discharge. Challenges include losses, bearing design, and material costs, but flywheels have been successfully implemented in applications from seconds to hours including spacecraft, locomotives, and military pulsed power.
As the penetration of renewable generation increased, it
had become obvious that the variability of these sources
and the fact that renewables are not always available when
the power is needed, were becoming a problem. As a
consequence, fossil-based operating reserves are required to
augment renewable generation to ensure reliability. Energy
storage can provide a superior solution to the variability
problem when compared to fossil-based generation, while
also improving the availability of renewables to provide
electricity upon demand. Energy storage is a flexible
resource for grid operators that can deliver a range of
grid services quickly and efficiently. The rapid growth of
policy mandates and incentives for renewable generation
and, more recently, for energy storage, the need for
modernization of the grid infrastructure, and the desire to
decarbonize the economy, are the principal drivers behind
the renewed interest in energy storage.

A 'gasoline-electric hybrid car' or 'Plug in hybrid electric vehicle' is a vehicle which relies not only on batteries but also on an internal combustion engine which drives a generator to provide the electricity and may also drive a wheel. It has great advantages over the previously used gasoline engine that drives the power from gasoline only. It also is a major source of air pollution. The objective is to design and fabricate a two wheeler hybrid electric vehicle powered by both battery and gasoline. The combination of both the power makes the vehicle dynamic in nature. It provides its owner with advantages in fuel economy and environmental impact over conventional automobiles. Hybrid electric vehicles combine an electric motor, battery and power system with an internal combustion engine to achieve better fuel economy and reduce toxic emissions.
In HEV, the battery alone provides power for low-speed driving conditions where internal combustion engines are least efficient. In accelerating, long highways, or hill climbing the electric motor provides additional power to assist the engine. This allows a smaller, more efficient engine to be used. Besides it also utilizes the concept of regenerative braking for optimized utilization of energy. Energy dissipated during braking in HEV is used in charging battery. Thus the vehicle is best suited for the growing urban areas with high traffic. Initially the designing of the vehicle in CAD, simulations of inverter and other models are done. Equipment and their cost analysis are done. It deals with the fabrication of the vehicle. This includes assembly of IC Engine and its components. The next phase consists of implementing the electric power drive and designing the controllers. The final stage would consist of increasing the efficiency of the vehicle in economic ways.
Energy storage system can actually store energy and use the stored energy whenever the need arises.
As the need for clean energy arises, the need to replace current existing power plants have become a global issue.

Energy storage systems are the set of methods and technologies used to store various forms of energy.
There are many different forms of energy storage
Batteries: a range of electrochemical storage solutions, including advanced chemistry batteries, flow batteries, and capacitors
Mechanical Storage: other innovative technologies to harness kinetic or gravitational energy to store electricity
Compressed Air: utilize compressed air to create energy reserves. Electricity can be converted into hydrogen by electrolysis. The hydrogen can be then stored and eventually re-electrified.
Pumped hydro-power: creates energy reserves by using gravity and the manipulation of water elevation
Thermal: capturing heat or cold to create energy
The choice of energy storage technology is typically dictated by application, economics, integration within the system, and the availability of resources.
Multiple Energy Storage Technologies are being developed & are maturing, Gensol did an analysis of 1635 Energy Storage Projects developed globally to come up with which technology has captured market share.

Wind energy is playing a critical role in the establishment of an environmentally sustainable low carbon economy. This paper presents an overview of wind turbine generator technologies and compares their advantages and drawbacks used for wind energy utilization. Traditionally, DC machines, synchronous machines and squirrel-cage induction machines have been used for small scale power generation. For medium and large wind turbines (WTs), the doubly-fed induction generator (DFIG) is currently the dominant technology while permanent magnet (PM), switched reluctance and high temperature superconducting generators are all extensively researched and developed over the years. In this paper, the topologies and features of these machines are discussed with special attention given to their practical considerations involved in the design, control and operation. It is hoped that this paper provides quick reference guidelines for developing wind turbine generation systems.
