Energy storage itself is not a new technology, but it seems that the concept of energy storage has become popular overnight. In September 2020, China promised to achieve carbon peak by 2030 and carbon neutrality by 2060, while Western countries aim to achieve carbon neutrality by 2050. Now, countries have reached a consensus on carbon emissions and have developed very strict standards. In the future, the key to whether a product can prosper is not whether it is useful, but whether it is environmentally friendly.
Under the carbon reduction target, electricity, as the central link of energy transformation and a key area for carbon reduction, has global significance for achieving the goal of carbon peak and carbon neutrality. As a major emitter of carbon, thermal power plants need to undergo significant changes under the requirements of transformation. Although China currently cannot do without thermal power generation, stopping and reducing thermal power is undoubtedly an important aspect to be taken seriously under the constraints of China's carbon peak and carbon neutrality goals. The future power generation method will gradually shift towards clean energy, such as nuclear power, hydropower, wind power, photovoltaic power, and biomass power. So, how can energy be stored?
How can energy be stored? Considering the advantages of comprehensive clean energy generation, wind energy and solar energy are inexhaustible resources, so wind power and photovoltaic power have no fuel cost constraints and have become the fastest growing industries in clean energy. In terms of installed capacity, wind power and photovoltaic power have the most potential to replace coal power. However, due to the instability of wind power and photovoltaic power generation and the problem of grid connection and consumption, they are still limited, which has also slowed down the pace of commercialization.
In short, wind power and photovoltaic power generation have a key weakness - unstable output, unable to achieve on-demand production. Both wind power and photovoltaic power generation rely on natural conditions, hence the need for "solar energy storage system". The emergence of energy storage will solve these shortcomings in power generation. How can energy be stored? Energy storage can regulate the randomness, fluctuations, and intermittency of wind and photovoltaic power generation, achieve complementary output in terms of wind, light, and storage, improve the predictability, controllability, and dispatchability of new energy generation, and make it reach or approach conventional power supply, solving the problems of safe and stable operation and effective consumption of new energy.
In the process of replacing fossil energy with new energy, energy storage technology can be said to be the core of the new energy industry revolution, and the energy storage market has also experienced explosive growth, which will inevitably lead to fierce competition in the new energy market. According to different capacity ranges, HEZON has developed effective and reliable methods for commercial, industrial, and household use, allowing renewable energy generated by the power system to be stored and used when needed.
