google's parent company alphabet wants to store renewable energy using salt in an attempt to save millions of megawatts of power each year - energy storage companies

To store renewable energy, Google's parent company turned to two unexpected resources-salt and antifreeze.
Alphabet, which owns Google, is developing a project code-named "malta" to store renewable energy that would otherwise be wasted.
If successful, the system can run almost anywhere, saving hundreds of megawatts of energy each year, which is repeatedly lost worldwide every year.
According to a Bloomberg report, the mysterious X department of the video alphabet is on the "moon landing" project in Malta.
According to X executives and researchers, the system may last longer than lithium.
Can compete with other clean energy storage methods.
X's director, felfelton, said in an interview with Bloomberg: "If the lunar probe factory abandons major issues like climate change, then it may never be resolved.
If we start to solve this problem, the market opportunity will reach trillions of dollars.
According to Felten MS, while there is no formal X project yet in Malta, the team of 10 researchers is now looking for partners to build and operate a prototype for the grid.
A lot of energy is wasted every year because there is no effective way to store it.
For example, in the first half of this year, California wasted 300,000 MW of energy from solar panels and wind farms, while China wasted more than it did, according to Bloomberg New Energy Finance.
The Malta system looks like a small power plant with four water tanks attached to the heat pump.
X says the system can have a variety of different sizes, from the same size as the garage to the full size
Expand traditional power plants as needed.
Julian Green, product manager in Malta, told Bloomberg when describing the system: "From a very simple point of view, imagine it as a refrigerator and a jet.
Two cylindrical cans are filled with salt, while the second is filled with antifreeze.
Energy enters the system in the form of electricity, which becomes a separation flow of hot and cold air.
Hot air heats salt when cold air cools antifreeze. To re-
Generating energy, the process is reversed, so that the hot and cold air rushes over each other, generating strong winds, rotating the turbine and generating energy again.
The system can store energy for several days according to the amount of insulation.
Mr. Green said: "The thermodynamic physics is very good --
People who study it in college know it.
"The trick is to do it with cheap materials at the right temperature.
This is very striking.
The project is now supported by Nobel Prize winner Robert Laughlin.
Physicist, his research is the basis of this system.
Mr. Laughlin said: "There is a blessing in the sky.
X came in and took a bite from this issue.
It is not clear when the system can be installed.
