Undecided - Why This Liquid That Stores Solar Energy for Years Matters, 02082022

'Heat' is a way we can store solar energy more directly (compared to Lithium-Ion batteries). For instance, concentrated solar energy plants can use that heat for producing electricity, cement, steel, green hydrogen, or anything else that needs high temperatures, or for storing that thermal energy for days. A recent breakthrough could allow us to store solar energy directly into a liquid for up to 18 years. How does it work? And could this be a viable path forward for solar energy storage?
