Thermal Energy Storage Market: Key Drivers, Trends, and Challenges
Based on our research output, there has been a negative impact on the market growth during and post COVID-19 era. The increasing demand for CSP is notably driving the thermal energy storage market growth, although factors such as competition from alternate sources of energy storage may impede market growth. Our research analysts have studied the historical data and deduced the key market drivers and the COVID-19 pandemic impact on the thermal energy storage industry. The holistic analysis of the drivers will help in deducing end goals and refining marketing strategies to gain a competitive edge.
Key Thermal Energy Storage Market Driver
One of the key factors driving the thermal energy storage market growth is the increasing demand for CSP. Thermal storage improves the system flexibility of solar plants by extending the contribution of solar electricity generation to improve their coincidence with the normal demand. Thermal energy storage accomplishes this by reducing the constraints of ramping and minimum generation levels in CSP plants. Thermal energy storage in CSP plants allows power to be generated even under severe weather circumstances with little or no loss in operating efficiency. In addition, the cost of generating power with CSP facilities has dropped dramatically in recent years. As a result of these causes, new CSP plants have been installed over time. Thermal energy storage is used in these facilities because it can sustain significantly higher temperatures than other storage technologies like as batteries. Therefore, thermal energy storage has become the primary source of energy storage in CSP plants. The rising demand for CSPs will drive the growth of the global thermal energy storage market.
Key Thermal Energy Storage Market Trend
Another key factor driving the thermal energy storage market growth is the growing demand for renewable energy sources. Renewable energy is a non-polluting, inexhaustible source of energy. It does not emit greenhouse gases or harmful pollutants, both of which are substantial contributors to climate change. As a result, renewable energy is regarded as one of the most dependable methods of electricity generation. According to the IEA, global electricity demand is expected to grow by 60%-70% by 2040, owing to population growth and rapid industrialization. Furthermore, during the projected period, global fossil fuel price volatility is expected to stimulate demand for renewable energy sources for power generation. The advantages of renewable energy, such as the creation of reliable, CO2-free baseload electricity and low reliance on imported fuels, are likely to increase demand for renewable energy, resulting in further growth of the sector.
Key Thermal Energy Storage Market Challenge
One of the key challenges to the thermal energy storage market growth is the competition from alternate sources of energy storage. Electricity grids require a balance between supply and demand at any given moment. It necessitates continual supply modifications to account for known demand variations as well as unanticipated changes owing to equipment overloads or force majeure events. These factors make it necessary for energy storage systems to create a balanced and reliable grid system. There are a variety of energy storage system technologies currently on the market, including battery energy storage systems (BESS), flywheel energy storage systems, hydrogen energy storage systems, compressed air energy storage (CAES) systems, and thermal energy storage systems. Other alternate storage technologies include the flywheel energy storage, which stores the electricity in the form of rotational energy; CAES, which improves the efficiencies of gas turbines by using the elastic potential energy of compressed air to store energy; and hydrogen energy storage, in which hydrogen is created to generate electricity for later use. The growing adoption of alternative technologies is a challenge for thermal energy storage systems, as it hinders the growth of the global thermal energy storage market.
This thermal energy storage market analysis report also provides detailed information on other upcoming trends and challenges that will have a far-reaching effect on the market growth. The actionable insights on the trends and challenges will help companies evaluate and develop growth strategies for 2021-2025.

COVID Impact and Recovery Analysis
In 2020, the outbreak of COVID-19 adversely affected the growth of the market in the region, owing to a decline in new capacity installations for different energy sources, including solar, hydro, and wind energy sources. A significant decline in the demand for electricity, temporary suspension of operations at new power plants due to lockdown measures implemented by governments of various countries, and disrupted supply chain are the major factors resulting in a decline in the consumption of thermal energy in the region. Therefore, with a decrease in new capacity installations and energy consumption, the market for thermal energy storage declined in the region during 2020. However, with the advent of vaccination drives in the region, the lockdown norms were lifted in the first half of 2021. This has led to an increase in industrial activities in the region, which, in turn, has led to a rise in power generation. Therefore, such factors are expected to boost the growth of the market during the forecast period.
