21 Best Energy Storage Companies & Manufacturers

As the world increasingly turns to renewable energy sources to combat climate change, energy storage companies are key to making sure that power stays on when the wind isn’t blowing and the sun isn’t shining.

Energy storage is an important part of the transition to a clean energy future. Wind and solar power are intermittent, meaning they only produce electricity when the wind is blowing or the sun is shining. That’s why energy storage is essential to ensuring a reliable supply of renewable energy.

What is Energy Storage?

In short, energy storage is a huge power bank that releases energy when the energy is insufficient, and stores energy when the energy is sufficient.

There are many different ways to store energy, but some of the most common methods include using batteries, pumped hydro, and compressed air. Each type of storage has its own advantages and disadvantages, so choosing the right technology depends on factors like cost, efficiency, and location.

Energy storage is divided into three categories according to technical principles, physical energy storage, electrochemical energy storage and electromagnetic energy storage.

Physical energy storage includes pumped hydro energy storage, compressed air energy storage, flywheel energy storage, etc.

Electrochemical energy storage includes lithium-ion batteries, lead-acid batteries, flow batteries, etc., and electromagnetic energy storage includes supercapacitors, superconducting electromagnetic energy storage, etc.

Among them, pumped storage is the energy storage method with the highest cumulative installed capacity in the world. It stores water during periods of low power load, and then releases it when the power load peaks, using gravitational potential energy to regenerate power.

By the end of 2021, the proportion of pumped storage in the global energy storage market will be lower than 90% for the first time, and China’s pumped storage will account for 86.3%.

Why is energy storage so important?

In order to achieve carbon neutrality goals, many countries have established new power systems based on new energy sources.

The main task of the new power system is to maximize the consumption of new energy. New energy is also called renewable energy, such as solar energy, wind energy, geothermal energy, hydrogen energy, etc.

Compared with conventional energy sources such as coal, oil, and natural gas, the most important feature is clean carbon, flexibility and efficiency.

The status of new energy power generation is becoming more and more important.

However, the biggest problem of new energy power generation is that it is too dependent on natural resources and energy is unstable. For example, the power generated by photovoltaics is very large at noon, but it is basically zero at night.

Therefore, the development of energy storage is the key to solving the problems of supply and demand matching and volatility in the new power system. Energy storage is so important, is he really going to rise?

Answers first. The energy storage industry is at an inflection point. What is the main driving force for the development of energy storage? To sum up three points, the short-term depends on policy-driven, the medium-term depends on the business model, and the long-term depends on cost reduction.

Market analysis of energy storage industry

The upstream of the energy storage industry chain mainly includes suppliers of battery raw materials, electronic components, etc.

The midstream mainly includes suppliers of battery systems, energy storage converters, energy management systems and other accessories, and the downstream includes energy storage system integrators, installers, etc. To end users including industrial and commercial power grid companies, wind and solar power plants, etc.

The application scenarios of energy storage are divided into power generation side, grid side and user side. The power generation side refers to the peak shaving and valley filling of renewable energy power generation by configuring energy storage.

On the grid side, the energy storage power station provides auxiliary services in the power market to ensure the stable operation of the grid. On the user side, the price difference is used for arbitrage to reduce the cost of electricity consumption. Energy storage faces the dilemma of low investment returns on both the power generation side and the grid side.

The most important means of making energy storage profitable is to reduce battery costs in the long term. To reduce the cost of the virgin system, either the battery cost will be reduced, or the battery cycle life will be improved.

Taking lithium batteries as an example, the energy density of lithium-ion batteries has nearly doubled in the past five years, the cycle life has more than doubled, and the cost of energy storage systems has dropped by about 60%. The inflection point of energy storage is known, how big is the future market space?

Take the Chinese market as an example. In 2025, the installed capacity of new energy storage in China will reach more than 30 million kilowatts, while by 2021, the cumulative installed capacity of new energy storage is only about 5.7 million kilowatts.

Therefore, by 2025, there will be at least 5 to 6 times more space for new energy storage installations, with an average annual compound growth rate of more than 50%. Energy storage has at least 5 to 6 times the installed capacity.
