Previously, electricity was primarily generated by the combustion of fossil fuels. However, issues with energy transportation, air pollution, and global warming have increased the use of renewable energy sources like wind and solar energy. This renewable energy source, however, is affected by climatic conditions, weather, geographical location, radiation intensity, and so on. As a result, there is a growing interest in energy storage solutions from many sources all over the world.

Why should energy be stored?

Why should energy be stored?

Vietnam has many favorable conditions and a high potential for developing renewable energy sources such as solar and wind power. Solar power generation, in particular, currently accounts for approximately 25% of the total capacity of the entire system (according to Electricity of Vietnam – EVN, 2021). However, because the solar radiation at noon (10h00 – 14h00) is high, the electrical energy produced by the panels is large, resulting in a line overload. Meanwhile, the peak time for electricity use shifts from 5:00 p.m. to 8:00 p.m., and the amount of radiation has decreased, reducing generating capacity.

Furthermore, the current transmission grid cannot keep up with the development of electricity sources, necessitating an urgent need to combine power storage technology with the development of renewable energy in order to postpone the time on upgrading the power grid.

Because of the aforementioned difficulties and deficiencies, the implementation of energy storage solutions is a critical and pressing issue.

Energy storage methods

Energy storage methods

A variety of methods and technologies can be used to store energy. Here are some examples:

  • Natural method

Storing fossil fuels such as coal, oil, and gas…

  • Mechanical method

Compressed air energy storage, steam locomotive; flywheel system and supercapacitor; gravitational potential energy; hydroelectric power plant (with pump).

  • Electrical and electromagnetic methods

Condensers, supercapacitors, superconducting magnets, and superconducting coils can all be used.

  • Biological method

Animals store energy as glycogen, while plants store it as starch.

  • BESS (Battery Energy Storage System) (electrochemical method)

Flow batteries (energy storage); lead-acid batteries; “ultra battery” battery; lithium-ion battery,…

  • Heat method

Energy storage through the use of a Eutectic cold storage system, liquid air energy storage, seasonal heat storage, and insulation

  • Chemical method

Storing energy in the form of biofuels; utilizing the reaction energy generated when salt is hydrated, hydrogen storage technology, and electricity-to-gas conversion technology

Some forms of energy storage

Stored hydroelectric power plant

Stored hydroelectricity works on the principle of storing electricity during times of low demand for use during times of high demand. As a result, the solar power plant does not generate additional electrical energy, but rather helps to coordinate the amount of electricity based on load (electricity demand) between peak and off-peak times.

CAES, the air compressor system

CAES operates on the same principles as a stored hydroelectric power plant. The difference is that instead of using a water flow rate to turn a turbine to generate electricity, CAES will heat the compressed air to release heat.

Flywheel energy storage

Flywheel Energy Storage (FESS) operates on the momentum conservation principle. Initially, electricity was used to rapidly rotate the flywheel. The flywheel will continue to rotate if it is not subjected to a strong force. It generates a large amount of kinetic energy as it spins, which it stores for later use. When this kinetic energy is converted into electricity, the flywheel’s rotation speed decreases.

Flow-charging battery

To generate an electrical charge, the flow battery combines two chemical components that are dissolved in a fluid separated by a membrane. By replacing the electrolyte liquid, the battery can be recharged. The flow battery system only requires the addition of electrolyte liquid to increase capacity, so storage capacity is determined by the volume of the solution.

BESS, the industrial energy storage systems.

The Battery Energy Storage System (BESS) is a type of energy storage technology solution that employs specially designed lithium-ion (Li-ion) batteries. The fundamental idea is that this stored energy can be used later. To balance energy production and consumption, these systems supplement energy sources such as solar and wind power.

Four energy storage solutions that will assist the world in achieving net zero

In its most recent estimate of what it will take to reach net zero, the consulting firm McKinsey describes a “fundamental transformation of the global economy” that will necessitate an annual investment of just over $9 trillion for decades. Decarbonizing the energy supply is an important and complicated component of the transformation. We’ll need a variety of solutions, including energy storage, which has emerged as a priority in recent years as a complement to widespread renewable energy use and the expansion of local electricity grids.


Renewable energy can be converted to hydrogen, then stored until needed before being converted back to electricity on demand.

One of the benefits of hydrogen is its scalability, which allows for long-term seasonal storage.

Synthetic fuels

Excess energy from renewable sources can be stored as synthetic fuel, such as methanol, which can be produced from green hydrogen and captured CO2. As a result, it is a net carbon-neutral fuel, and demand for it is rapidly increasing: To 2027, the global methanol market is expected to grow at a compound annual growth rate of 4.6 percent.

Because synthetic fuels are easy to store and require little infrastructure investment, they can help usher in a net-zero transportation future.


Electric vehicle adoption has been boosted by a growing awareness of the need to decarbonize, as well as government policies phasing out the internal combustion engine (EVs). EV sales reached 6.6 million in 2021, more than tripling their market share from two years earlier.

EVs can store surplus electricity each time they are charged, feeding it back into the grid to make up for shortfalls during times of high demand. Utility companies will be able to use any excess electricity more efficiently as more electric charging stations are added to roadsides, homes, and commercial real estate.


Advances in lithium-ion battery development are expected to increase storage, allowing batteries to power thousands of homes in the near future. Lithium-ion technologies can be scaled up as needed as a source of backup energy to the grid by storing an electrical charge in tanks of liquid electrolytes.

Such energy storage systems could one day be used in multi-unit apartment buildings, bringing us closer to a future of energy-efficient, low-carbon cities.
