Battery electricity storage: key technology for the energy future

The use of battery power storage: A key technology for the energy future

Power storage is one of the key technologies that play a significant role in the energy transition. It makes it possible to store energy that has been generated and release it again at a later time when demand is higher or when renewable energies such as solar or wind are not available. This flexibility is crucial to ensure a reliable and sustainable energy supply. Below we give you an overview of the use of power storage, its advantages, challenges and our battery specialization, which is available on the market.

1. Introduction to the world of battery storage
Our battery storage systems are technical systems and facilities that store electrical energy in the form of chemical energy in order to release it later according to your needs. This storage technology is often used to temporarily store excess energy, for example generated from renewable energy sources such as solar or wind power plants, and to use it at a later time when electricity production from these sources decreases or demand increases. The lithium iron phosphate batteries we use are the most efficient technology in modern battery storage systems, both in private households and in large industrial plants, due to their high energy density and long service life (8,000 cycles).

2. The importance of electricity storage for the energy transition
Renewable energies such as solar and wind power have the advantage of being climate-friendly and sustainable. However, they also pose a major challenge: they are not always available when electricity demand is high. An electricity storage system can help overcome this challenge by storing excess energy that can then be used when the production of renewable electricity is not sufficient.
For example, a battery storage system can store the excess energy generated by solar cells during the day and feed it back into the grid at night or on cloudy days. In this way, the use of renewable energy is optimized and dependence on fossil fuels is reduced.

3. Advantages of electricity storage
The use of electricity storage brings a number of advantages:
• Flexibility and grid stability: Power storage systems can react to fluctuations in the power grid in real time and thus help to stabilize the grid. They are able to absorb excess energy and release it again quickly when needed, which increases the reliability of the energy supply. In this way, they support the frequency stability of the grid by reacting quickly to frequency fluctuations and either feeding in or absorbing energy. This avoids potential grid instabilities and power outages. The power storage systems can also help to maintain a stable grid voltage by balancing out voltage fluctuations.
• Energy independence: Battery storage systems are particularly suitable for private households and companies in order to reduce dependence on public power grids or to achieve complete self-sufficiency. For example, if you have a photovoltaic system, you can use a suitable battery storage system to store the electricity generated for your own use and use it as needed. In households and companies, battery storage systems therefore serve as a backup system to maintain the power supply in the event of a power failure.By temporarily storing energy, electricity storage systems can cut load peaks and thus counteract overloading of the network infrastructure. This in turn leads to an extended service life of the required network elements and reduces the need for costly expansions and retrofitting.
• Optimization of energy costs: By storing electricity, you as a consumer can take advantage of cheap energy prices when you charge your battery storage and use this energy at a later time when electricity prices have increased. This is particularly beneficial in markets with variable electricity tariffs. These dynamic electricity prices do not have a constant price for the respective electricity consumption, but change depending on market conditions (e.g. supply and demand). This means that prices are higher or lower at certain times. The unpredictability of electricity prices can be detrimental to consumers, especially if individual electricity consumption cannot be adjusted to the low-price times.
• Reduction of CO2 emissions: Storing and using excess electricity from renewable energy sources helps reduce the use of fossil fuels and lower CO2 emissions in the energy sector. This serves as an important building block in limiting global warming and minimizing the negative effects of climate change.

4. Challenges in the use of battery power storage
Although battery power storage offers numerous advantages, there are also challenges that need to be addressed and overcome.
The initial cost of battery energy storage, such as our more advanced lithium-ion batteries, can be higher than other energy storage models. However, lithium-ion batteries are proving to be the backbone of many modern technologies. Their cost has long had a significant impact on overall prices, such as those of electric cars and other battery-powered devices. In recent years, however, several factors have led to a significant price reduction. Government subsidies and incentives have significantly reduced the price of battery cells. These subsidies, the associated tax incentives for battery production and investments in research and development promote the technology (for example, improving cell chemistry or optimizing production processes) and help to further reduce costs.

5. Areas of application of electricity storage systems
Power storage systems are used in various areas, both in the private and in the commercial and industrial sectors:
• Private households: In combination with photovoltaic systems, battery storage systems offer an excellent opportunity to store solar power for your own use and to optimize energy consumption.
• Industry and Commerce: Companies that consume large amounts of electricity can use electricity storage to reduce their energy costs and make their energy supply more flexible. Battery storage also plays an important role here, but technologies such as compressed air and pumped storage power plants are also of interest.
• power grids: Large electricity storage facilities are important for grid operators to ensure the stability of the grid and to cushion peak loads. They can help to balance out short-term fluctuations in electricity production and demand and thus make the operation of electricity grids more efficient.

6thOutlook: The Future of Power Storage
Electricity storage technology has made enormous progress in recent years, and it will continue to play a central role in the transition to a greener and more sustainable energy supply. The expansion of energy storage is being driven by increasing innovations in battery technology, the expansion of renewable energies and the improvement of recycling technologies.
Of particular interest is the development of larger, more cost-effective and more sustainable storage technologies that are suitable for broader use in industry and the public sector. New approaches such as solid-state batteries or liquid energy storage could be even more efficient and environmentally friendly in the future.
In addition, intelligent smart grid technologies and artificial intelligence are increasingly being integrated into the management and control of electricity storage systems in order to optimize their use and improve interaction with the power grid.

Conclusion
Electricity storage is an indispensable tool on the way to a more sustainable and flexible energy future. It helps to meet the challenges of the energy transition by enabling the integration of renewable energies, stabilizing the energy supply and helping consumers reduce their energy costs. Despite some challenges, especially in terms of costs and recycling, electricity storage offers a promising solution for the future of energy supply and plays a crucial role in the transformation towards a climate-neutral society.
