The latest salt-melting device can provide electricity 24 hours a day, which can greatly reduce the electricity fee
In addition to solar and wind energy, clean energy companies are also considering using molten salt to generate electricity. Specifically, "Solar Reserve" is one of several companies trying to prove that molten salt can generate electricity as efficiently as solar energy and wind energy. In 2015, Solar Reserves launched a 1,100 MW crescent-shaped dune solar facility in Nevada, USA, capable of generating 1,100 megawatt-hours of energy storage and supplying electricity to 75,000 families in Nevada.
“Solar Reserve†company established Redstone Solar Project in Africa.
Similar "Concentrated Solar Energy (CSP)" projects will be implemented in southern Australia, Africa, Chile and other countries around the world.
Unlike salt and wind power generation, the latter can only produce electricity to reduce the demand for fossil fuels, and solar power and wind power can be used to run electricity at any time, 24 hours a day. Store electricity for up to 10 hours. This type of power generation is very simple. Sunlight is focused on a tower-like device that can heat molten salt above 1000 degrees Fahrenheit and then used to make steam and turn the turbine.
At the same time, the cost of the salt-water power plant is low. It is alleged that the cost of manufacturing a 1 kWh electricity at the new moon-shaped sand dune power plant in Nevada is $0.06. If a recent study by the International Renewable Energy Agency (IRENA) is predictable, the price of the power plant will become even lower.
Even according to their own standards, the reserve reserves of solar reserve companies began to gradually decrease. The crescent-shaped sand dune power station can produce 500,000 megawatt-hours (MWh) of electricity each year, but media reports show that it has not yet reached this target.
At the same time, Spain’s Sener Engineering Company has two projects in the Ouarzazate area of ​​Morocco, where it uses molten salt. The prices of the two projects are not low enough, but the expected price drop may put the company in a good position to advance the progress of the “Concentrated Solar Energy†project. Currently, Google also plans to store renewable energy in molten salt, but the plan still needs to be tested systematically to determine whether it can be used for commercial purposes.
Before solar energy can be provided 24 hours a day by solar concentrator solar (CSPs) projects, utility officials and energy policy makers need to understand the importance of energy storage and when renewable energy is needed. Kevin Smith, chief executive of Solar Energy Reserves, pointed out that public facilities in the United States only want to obtain electricity. In other words, they are not concerned about the use of renewable energy.
Smith explained that things are gradually changing. For example, in some parts of California, USA, a large amount of renewable energy will be generated at a specific time of the day, only when the official dialogue is switched to how to deal with these excess energy, and how to construct an integrated power grid. This problem can be solved.
