#科技头条#【用盐储存能源这种操作,也就谷歌玩儿得出来了】谷歌母公司Alphabet正在进行一个名为Malta的项目,打算用盛着盐和防冻液的罐子作为容器,储存太阳能电池板或风力发电机产生的电热能。研究人员表示,这项技术的成本会比现有的锂电池和其它存储技术低上数倍。

Google's parent company Alphabet wants to store renewable energy using SALT in an attempt to save millions of megawatts of power each year

  • Alphabet, which owns Google, is working on the project under code name Malta
  • The system is made up of four cylinders - 2 filled with salt, and 2 with antifreeze
  • Energy is taken into the system, where it is tranformed into hot and cold air
  • The hot air heats up the salt, while the cold air cools the antifreeze
  • To recover the energy, the process is reversed, powering a wind turbine 
  • It is unclear when the system will be ready to be installed 

In an attempt to store renewable energy, Google's parent company is turning to two rather unexpected resources – salt and antifreeze.

Alphabet, which owns Google, is working on a project under the code name 'Malta' to store renewable energy that would otherwise be wasted.

If successful, the system could be located almost anywhere, saving millions of megawatts of energy that are currently lost worldwide each year.

THE MALTA SYSTEM

The Malta system looks like a small power plant, with four tanks connected to a heat pump.

X says the system can come in various different sizes, ranging from the same size as a garage, to a full-scale traditional power plant, depending on needs.

Two of the cylindrical tanks are filled with salt, while the second two are filled with antifreeze.

Energy is taken into the system in the form of electricity, which is turned into separate streams of hot and cold air.

The hot air heats up the salt, while the cold air cools the antifreeze.

To re-generate the energy, the process is reversed, so that the hot and cold air rush towards each other.

This creates powerful winds that spin a turbine, producing the energy once again.

The system can store the energy for days, depending on the amount of insulation.

Alphabet's mysterious X division is working on the 'moonshot' project Malta, according to a report in Bloomberg.

According to X executives and researchers, the system has the potential to last longer than lithium-ion batteries, and could compete with other clean energy storage methods.

Speaking to Bloomberg, Obi Felton, director at X, said: 'If the moonshot factory gives up on a big, important problem like climate change, then maybe it will never get solved.

'If we do start solving it, there are trillions and trillions of dollars in market opportunity.'

While Malta is not yet an official X project, the team of 10 researchers is now looking for partners to build and operate a prototype to the grid, according to Ms Felten.

Each year, huge amounts of energy are wasted, because there is no efficient way to store it.

For example, in the first half of this year, California wasted 300,000 megawatts of energy produced by solar panels and wind farms, while China threw out more than 17 per cent of its energy produced, according to Bloomberg New Energy Finance.

Describing the system, Julian Green, the product manager for Malta told Bloomberg: 'Think of this, at a very simple level, as a fridge and a jet.'

Mr Green said: 'The thermodynamic physics are well-known to anyone who studied it enough in college.

The project now has the backing of Robert Laughlin, a Nobel prize-winning physcists whose research is the basis for the system. It is unclear when the system will be ready for installation

'The trick is doing it at the right temperatures, with cheap materials. That is super compelling.'

Mr Laughlin said: 'A blessing came out of the sky. X came in and took a giant bite out of this problem.'

It is unclear when the system will be ready for installation.
