As the United States and other countries face growing global electricity demand and the need to reduce greenhouse gas emissions that contribute to climate change deterioration, the fight to build better batteries is intensifying, seeking to expand carbon emissions
Free renewable energy such as wind energy and solar energy.
S. today Energy News is the key.
They can power electric cars and buses directly or indirectly for homes and large buildings by storing solar and wind energy when the sun does not shine and the wind does not blow.
They balance renewable energy sources that produce energy intermittently, so consumers can power laptops or refrigerators 24/7 of the time. The race is on.

\"This is the dawn of energy --
\"Storage times,\" said Bill Radvak, president of American Vanadium Company, which partnered with German battery maker Gildemeister.
Storage could be the \"holy grail\" of renewable energy, he said \".
\"There was no major battery market three years ago,\" he said . \" The situation is changing rapidly, he added.
In February, California requested 33% of its electricity from renewable sources by 2020, requiring Los Angeles-
Ensure that part of the capacity comes from regional utilities for energy storage.
In May 1, Germany began subsidizing homeowners to buy batteries to store electricity from solar panels, and Germany is shutting down nuclear power plants to boost renewable energy. China\'s five-
The annual plan requires 5% of all electricity to be stored by 2020.
In the United States, the most common form of energy storage is pumped storage, which is about 2% of the power capacity.
According to a report from IMS Research this month, the global market for solar panels to store electricity is expected to explode, from less than $0. 2 billion in 2012 to $19 billion in 2017.
One factor driving this growth is the slump in renewable energy prices, especially solar panels, which have fallen by at least 60% since the beginning of 2011.
As a result, with the development of the US economy, the industrial group reported historic growth. S.
In the last year alone, the power generation of solar panels increased by 76%, and the power generation of wind turbines increased by 28%.
Obstacles to the battery include cost and safety. Lithium-
On January, ion batteries on two Boeing 787 jets failed, causing one aircraft to catch fire and another to smoke.

A series of batteries using magnesium instead of lithium.
However, there are still a few years to go before commercializing.
\"Batteries are still a challenge,\" Esther Takeuchi, a chemistry professor at SUNY Stony Brook, said at the same meeting, especially electric vehicles.
\"Things are not what we want, but they are getting closer and closer.
\"Her university and some other universities with federal funding are not only focusing on new chemical mixtures, but also on nanometers.

Batteries are just one of the many ways to store the gridscale energy.
The most common is pumping water and electricity, in which water is delivered to the reservoir and then released to run the generator.
\"Storage is the glue that connects the grid together,\" said Matthew Malone of GE Energy . \".

Earlier this month it was announced that Nvidia will install its brilliant wind turbine with Durathon Batteries at a wind farm in Texas later this year. The U. S.
The government is promoting energy storage.
On November, DOE announced grants for 23 R & D projects and selected the Argonne National Laboratory in the sick Lemmon.
As the first national innovation center for batteries and energy storage \".
Within five years, Argonne will receive $0. 12 billion in revenue.
Batteries have received special attention because of their wide use.
Although pumping water and electricity facilities require a large amount of land and water and are used for utilities --
Scale projects, batteries can be used anywhere and are easy to scale, so they can power not only the car, but also the factory.
\"Everyone finally realized, \'Hey, this works. \'. . .
This is the key to the future, \"said Brad Roberts of the power storage association of the industry group.
The industry\'s problems are part of its growth, he said, adding: \"I don\'t see any hesitation from venture capitalists.
\"The replacement for Allan Schurr at WORKSIBM is very optimistic about his company\'s new lithium --
The air battery, which absorbs oxygen from the air, forms a chemical reaction that generates a charge.
It\'s lighter and more dense than lithium.
Most electric vehicles today use heavy metal oxides to drive ions that produce chemical reactions to electricity.
\"So far, we have seen performance in our tests that has met or exceeded our expectations,\" he said . \".
He said, charging 500 miles at a time, \"you will remove \'remote anxie\' from the equation.
\"The current Nissan Leaf can drive 75 miles on a single charge, Mitsubishi I-MiEV, 62 miles.

Radvak said that if his project is approved, it can provide 5% of the world\'s vanadium supply and help reduce battery costs.
The Land Authority is reviewing the project and will hold a public meeting on Tuesday in Eureka, which said the mine could lead to the loss of larger pine chicken habitat and livestock grazing areas.
\"There are no consequences for mining operations,\" Radvak said . \".
But he said that the Eureka Mine does not need to move a large number of the Earth, because vanadium is in the surface sediment and can be simply leaching with sulfuric acid.
\"This is a very low one.

Lagging behind other countries in energy storage, especially Germany, he expects Germany to be the world leader in the long run.
Common battery vocabulary: even with different metals, batteries often work in the same basic way.
They are small power plants that generate electricity by generating chemical reactions.
When atoms move between two different metals through a chemical solution called an electrolyte, the voltage they produce is discharged through the metal wire on the other side. Lead-
Acid: (automatic ignition ).
Their atoms are transferred from metal lead plates to solid oxidized lead plates through sulfuric acid. Lithium-
Personal electronic products, electric vehicles.
They have carbon at one end and metal oxides at the other end, using lithium salt from organic compounds as electrolyte in the middle. Lithium-
