The energy transition is a process of fundamental change in the way energy is generated, transmitted and consumed. In an era of growing demand for sustainable energy, energy storage plays a key role in integrating renewable energy sources and in building flexible, low-carbon energy systems. The future of the energy sector rests on an effective and safe energy transition, in which energy storage forms the foundation for development and makes a significant contribution to the growth of green energy.

What is the energy transition?

The energy transition involves moving away from traditional fossil fuels towards modern and environmentally friendly solutions:

• the use of renewable energy sources (RES), such as solar, wind and biomass,
• improving energy efficiency at every stage of the process,
• the development of smart grids,
• the decentralisation of the electricity system, which increases its resilience to outages.

Such an energy transition is essential to switch to green energy and reduce greenhouse gas emissions, thereby building a safer and greener future for future generations.

Why are energy storage systems the cornerstone of the future of the energy sector?

Energy storage plays a crucial role in the energy transition, enabling an effective response to the challenges posed by the intermittency of renewable energy sources (RES) and improving the flexibility and security of the electricity system.

Balancing unstable RES

Energy from photovoltaics and wind power is variable and dependent on weather conditions, which poses challenges to the stability of the system. Energy storage enables:

• the storage of surplus energy during periods of high production,
• the release of stored energy when production falls,
• the smooth management of supply and demand within the electricity system.

Thanks to these functions, energy storage facilities contribute to the stabilisation of the entire electricity system.

Reducing emissions and easing the strain on the grid

Energy storage facilities support the decarbonisation of the energy sector, which is a key objective of the energy transition. They enable:

• a reduction in the use of coal-fired power stations,
• the strengthening of local energy systems and microgrids,
• and a reduction in the pressure to upgrade costly transmission grids.

Such measures directly contribute to reducing the carbon footprint and support the development of green energy.

System flexibility and security

Energy storage systems enhance the flexibility of the power system, which is one of its most important features in modern power engineering. They enable network operators to:

• secure power reserves in the event of failures or sudden spikes in demand,
• effectively manage peak demand (peak shaving), which reduces grid loads at critical moments,
• increase the system’s resilience to blackouts and other disruptions, thereby ensuring the reliability of energy supply.

Thanks to energy storage in the energy transition, the flexibility of the energy system is significantly higher, allowing for better adaptation to dynamic conditions of energy production and consumption and increasing the security of the entire system.

Energy storage in Europe and Poland – current trends

Europe recognises energy storage as a key element in achieving the energy transition. The European Commission forecasts that storage capacity will need to be increased to over 200 GW by 2030. Investments are focusing on modern technologies, such as lithium-ion systems, hydrogen-based storage and heat pumps, which will become a pillar of the European Green Deal.

Energy storage facilities in Poland are also playing an increasingly important role in the development of the energy sector. Under national strategies such as the KPEiK and PEP2040, energy storage is treated as a strategic technology supporting the development of renewable energy sources (RES), grid digitalisation and the dynamic growth of prosumerism. Poland is stepping up investment in energy storage, drawing on significant support from EU funds such as the National Recovery Plan (KPO) and other EU programmes.

The growing importance of energy storage in Poland directly contributes to the stability of the national electricity system and enables better adaptation to dynamic changes in the energy market. In this way, energy storage in Poland is becoming an indispensable element of the future of the energy sector, whilst supporting the country’s environmental and economic objectives.

Frequently asked questions:

Why are energy storage systems important in the energy transition?

Energy storage plays a key role in stabilising renewable energy sources (RES), which, due to their intermittency, require effective balancing. They allow surplus energy to be stored during periods of low demand and released when renewable generation drops. As a result, they reduce harmful greenhouse gas emissions by reducing the need to rely on fossil fuel-fired power stations. Furthermore, energy storage facilities enhance the security of the electricity system by providing power reserves and flexibility in managing energy flows, which translates into greater reliability of supply.

Is Poland investing in energy storage?

Yes, Poland is investing very actively in the development of energy storage, which is an integral part of national energy strategies such as the Polish Energy Policy 2040 (PEP2040) and the National Energy and Climate Plan (KPEiK). Financial support also comes from EU programmes such as the National Recovery Plan (KPO) and FEnIKS. Thanks to this, Poland is accelerating the implementation of modern energy storage solutions, which are essential to support the development of renewable energy sources, grid digitalisation and an increase in the share of prosumers.

Which energy storage technologies dominate?

The dominant energy storage technologies include lithium-ion systems, which are characterised by high energy density and long service life. There is also growing interest in the use of hydrogen as an energy carrier, particularly with a view to large-scale storage and integration with industry. In addition, battery container systems are popular; they are mobile and scalable, allowing for flexible deployment in various environments. Thermal storage systems are also significant, as they store energy in the form of heat, which is later used for heating or generating electricity.
