Energy storage technologies and flexibility solutions are indispensable components that facilitate the transformation of energy systems towards sustainability and decarbonization. With increasing penetration of renewable energy sources, there is a need to apply technologies such as battery storage, thermal storage, hydrogen storage, smart grids, and demand response solutions to ensure balance between supply and demand for electricity, improve grid reliability, and increase energy resilience. The Journal of Energy Transition and Net-Zero Technologies encourages submissions of papers dealing with various energy storage technologies, smart grid systems, and other energy management solutions related to renewable energy integration.
