Concentrated solar thermal. As mentioned above, concentrated solar thermal power can be used in conjunction with a heat storage system. This means that, unlike most forms of solar energy, concentrated solar thermal power can provide baseload or dispatchable energy. This may be a very important innovation for renewable energy in general.
1. INTRODUCTION. As the global climate continues to deteriorate, reducing carbon emissions and building a low-carbon society is the consensus of all countries in the world [1]. Since China announced its carbon peak and carbon neutral goals in 2020, the concept of a "low carbon" future has garnered attention across various domains [2].
Video. MITEI''s three-year Future of Energy Storage study explored the role that energy storage can play in fighting climate change and in the global adoption of clean energy grids. Replacing fossil fuel-based power generation with power generation from wind and solar resources is a key strategy for decarbonizing electricity.
