Energy storage: from compressed air to nanotubes

With the imminent energy crisis it is necessary to develop new systems of energy storage. Currently there are a large number of technologies forenergy storage (or energy storage) but what we have doesn't seem to be enough.

Energy storage for electric mobility
Currently, research for the development of new systems forenergy storage is financed by car manufacturers for the expansion of the electric mobility sector. Research is aimed at developing more efficient lithium-air, sodium-air, lithium-ion batteries, while salt batteries and solid electrolyte accumulators have already spread successfully. The hunt for systems forenergy storage in the automotive sector it is also strongly desired for the diffusion of hydrogen cars and compressed air cars.

Energy storage, power plants
One of the techniques of energy storage the oldest is the transformation of energy. In modern days, the most striking example is given by the hydroelectric plants that "they store energy"Exploiting the water: at night the power stations pump water into a sort of dam / cirsterna. During the day, when the energy demand rises, the power plants drop the water which, as it flows, drives a turbine capable of producing electricity. Other forms of energy storage through "transformations " can be found with the conversion of energy in the form of heat or in the form of compressed air.

Energy storage, compressed air
A practical example is to use the energy produced by the solar panel to power a compressor that pumps air into a tank. To reuse the energy produced, just let the air out and use it to power an electricity generator. One of the main problems of compressed air energy is its efficiency since the heat created by the process is still lost.

Energy storage in the renewable energy sector
To lighten the national electricity grid, Germany has provided incentives for the purchase of energy storage vital when it comes to renewable energy. Still in Germany, however storing energy produced from clean sources such as the sun and wind, a rather complex but effective system has been developed: it starts from the kinetic energy of the rotational movement of the wind turbines, passes through hydrogen and ends with the storage of biogas. A real Energy Trio: wind, hydrogen, biogas.

Energy storage in the home
Even in the home, the need may arise to adopt a system of energy storage to store the energy produced by the photovoltaic roof or by the domestic wind. There are many new generation wind turbines that incorporate an energy storage system in the column, as well as numerous solutions for energy storage proposed by companies in the sector. So, whoever wants storing energy clean produced by your plant can choose one of the products offered by the market, an example are Panasonic accumulators, storage devices such as Energy Storage E3 DC, SMA Solar Technology ... other solutions to be applied in the home are shown in this article.

Energy storage with your own electric car
Anyone who owns an electric car can storing electricity produced by its own systems using the car's internal storage system. To understand what we are talking about, read Cars that become photovoltaic accumulators.

Energy storage, hydrogen
Hydrogen is a precious resource, it does not exist in nature in free form and for this reason it is defined as a "energy vector ". Hydrogen is an energy source with infinite applications, thus,energy storage in the form of hydrogen is a great opportunity for all the sectors mentioned above, from the automotive to the strictly energy sector.

Storing hydrogen is not at all simple, the latest technology created forenergy storage in the form of hydrogen involves the use of carbon nanotubes. L'hydrogen it can be stored in liquid or gaseous form, in the first case the big limit is given by the possibility of maintaining a suitable pressure, in the second case, the limit is imposed by the volume: large spaces are needed to store hydrogen in gaseous form. Discover all the systems for storing hydrogen.
