The global energy transition is increasingly dependent on advancements in thermal engineering and energy storage technologies. In Portugal, the government has introduced a National Strategy for Energy Storage to reach 6.9 GW of capacity by 2030, focusing on technologies like batteries and pumped hydro to manage renewable intermittency.

On a broader scale, the residential energy storage market is seeing rapid growth, with global capacity projected to reach 46.1 TWh. Europe, led by Germany, Italy, and Austria, remains a central market, while interest is growing in Asia and Oceania. The manufacturing sector is highly competitive, with companies such as ESS, Sigenergy, and Deye maintaining significant market shares.
