A fluid can store solar energy and then release it as heat months later
A DNA-inspired breakthrough could finally solve seasonal solar energy storage.
Deep Dive
Researchers have developed a fluid that stores solar energy in chemical bonds for months and releases it as heat on command. Inspired by DNA damage from sunburn, the system uses a modified molecule that folds under sunlight and unfolds to release heat. This molecular solar thermal (MOST) storage approach aims to overcome the major limitation of storing solar heat for long periods, potentially competing with fossil fuels for heating, which accounts for nearly half of global energy demand.
Why It Matters
This could decarbonize heating by providing a renewable, storable alternative to natural gas and heating oil.
