Introduction
Today's world of competition, green energy
plays an important role. For zero emission in 2050 is expecting growth in using
solar and wind energy. We should have to store this for a short period, which
will be the good days of batteries. In 2070 man will construct cities on ocean
surfaces.
Energy conception is linked with a
countries growth. Government will try to raise GDP in every possible ways to
generate and consume maximum energy. Fossil fuels and uranium quantities are
small never increase only decreasing
R and D in battery manufacturing is till
going on. Some achievements are got.
One Sun and One World
Climate change has been a problem of the
present world. Entropy is ever increasing, do it possible to decrease it by
changes electricity. Solar energy must be using, which is cheap and richly
available. A solar energy power grid is a universal need.
Types of Energy Storages
These can be grouped in to five technology
categories., Batteries, Thermal,
Mechanical, Pumped hydro and hydrogen. There are 12 types of batteries in
common use. Metal-air and flow batteries are new additions to the list.
Present Scenario
Energy storage will reach cost parity with
conventional technologies and soon its growth will get faster. Global li-ion
battery manufacturing in 2010 was 10GWh, this became 500GWh in 2020 and could
exceed2000GWhin 2025. Battery storage is essential for solar projects in
universal power grid
Engineers and scientists must hard work for
cheaper storage of energy for long duration. Several types of batteries are in
the market. A new type of battery is under development having infinite number
of charges. Energy storage systems play a major role in grid management.
Actually it is a power station.
Conclusion
Long duration storage can be able to supply
electricity during natural calamities. Engineers and technicians are to be
trained for operating virtual power station made by batteries.
