batteries of ice, iron and glass store renewable power - battery energy storage system

We had to turn to coal and gas when the wind stopped blowing and the turbine slowed down
Power stations that meet our energy needs.
This unpredictable nature makes it difficult to rely on renewable energy for sustained energy supplies.
Storage is a solution, but it is expensive for traditional batteries to hold enough power.
General Electric Portland (PGE)
Oregon has become ice.
The company will soon launch a pilot project to use cold mud to store their energy when wind turbines are overproducing, and use it when the turbines are still.
This is just an innovative solution to the growing problem.
Last year, California passed legislation requiring more than one energy company in the state to create.
By 2020, the energy storage between them reached 3 gigawatts.
Lithium-ion batteries seem to be the obvious solution.
These batteries are a mature technology, and Elon Musk announced plans to spend & dollars last week;
2 billion, develop a large number of electric vehicles for his electric vehicle company Tesla Motors.
But while they are perfect for electric sports cars, the batteries are not cheap and flexible enough to cope with the various loads stored in the grid.
Cold solution of PGE, a thermal method for energy storage in power grid (TAGES)
Developed by a company called Applied.
It uses a heat pump, driven by excess energy generated by wind turbines or solar panels, to cool water into pumped smoothies and store it.
Slush uses a heat pump in another way to recover energy and power the turbine when it melts.
Using the waste heat of the coal-fired power plant to power the heat pump means that the energy of 80 that enters slush can be recovered.

Portland, Oregon, is also using a mobile battery with a solution containing iron and water.
By injecting iron ions with excess electrons, electricity is stored in the system.
When electricity is needed, the iron is pulled between the two electrodes, which peel off the excess electrons.
The company plans to install a lithium-ion battery in a local vineyard to help growers balance their energy more effectively and get more energy from solar panels and wind turbines.
Lithium-ion batteries should help vineyards get more from solar panels and wind turbines. A more familiar material is being used for energy storage glass.
The halogen process Company in emmerville, California has developed a phosphate-
The base glass with a melting point low enough to make it a storage medium.
"We are developing a glass that can be pumped like a liquid," said Justin Raade, CEO of halotechcrunch . ".
"Its viscosity is several orders of magnitude lower than that of traditional window glass, and at 400 °c its viscosity is about the viscosity of honey.
"Glass can be pumped to where energy is needed.
When it cools and sets, it releases heat and drives the steam turbine to generate electricity.
Raade plans to install a pilot version at the aluminum plant.
The glass energy capture system will recover the waste heat in the smelting process to improve energy efficiency.
Chris Dieterle, a power analyst at PGE, said the new batteries are promising in dealing with renewable energy.
California's legislation changed the rules of the game, he said.
"It sends a message to others that this is a very serious problem that needs some breakthroughs.
