Energy storage: no more “squandering” of energy
Have you ever wondered why we can't just save our excess electricity for later?
Well, we've been doing that for a long time! It's all about energy storage.
What is energy storage?
Energy storage, simply put, is the process of storing excess energy until it is needed and then taking it out and using it. It's like keeping food in the refrigerator and taking it out to eat when we're hungry.
Why do we need energy storage?
Balancing supply and demand: The amount of electricity generated from clean energy sources such as solar and wind can be affected by weather and fluctuate greatly. Energy storage balances supply and demand on the grid by storing excess electricity and releasing it at peak times.
Improve energy utilization: For example, we can charge an electric car at night when electricity consumption is low, using electricity with lower tariffs, and then use the on-board electricity to power the home during the day.
Improve energy security: Energy storage systems can be used as a back-up power source to provide electricity in the event of an unexpected power outage, safeguarding our livelihoods.
Common types of energy storage
Battery storage: The most common type is the lithium battery used in our cell phones and computers. Large battery storage systems can provide power for homes, neighborhoods and even the entire power grid.
Pumped storage: Using excess electricity to pump water to a higher elevation and then releasing the water to generate electricity when it is needed. This is used on a large scale in areas with abundant water resources.
Flywheel energy storage: Converting electrical energy into kinetic energy by making a huge flywheel spin at high speed and then converting the kinetic energy into electrical energy when electricity is needed.
Compressed air energy storage: compressed air is utilized to compress excess electricity, stored in underground caves or man-made containers, and then released when electricity is needed to push the turbine to generate electricity.
Application Scenarios of Energy Storage Products
Home: Home energy storage systems can help families reduce their electricity bills and increase their self-sufficiency in electricity consumption.
Industrial: Industrial enterprises can utilize energy storage systems to smooth out the peak and valley differences in electricity consumption and reduce electricity expenses.
Grid: Large-scale energy storage systems can improve the stability of the grid and promote the development and utilization of new energy sources.
Electric vehicles: The battery of an electric vehicle is a kind of energy storage device, which can convert electrical energy into kinetic energy to drive the vehicle.
The future of energy storage
With the continuous progress of science and technology, energy storage technology will become more and more mature, and the cost will become lower and lower. In the future, energy storage will play an increasingly important role in our lives, bringing us a cleaner, more efficient and convenient energy life.
Energy storage, make our life better!
