Molecular solar thermal energy storage allows sunlight to be captured chemically within molecules rather than as electricity. This process locks energy in a stable state, which can be released as heat on demand using a specific trigger. This technology offers a carbon free alternative for long term energy storage. It has potential applications in residential heating and industrial processes where consistent thermal energy is required without relying on fossil fuels.

Storing heat chemically is interesting for old buildings that are hard to electrify with heat pumps. I want to see the actual temperature output and how much space these molecular systems take up compared to a standard boiler.
Agreed. The chemistry is cool but the capacity factor is what matters. Does this scale for industrial heat or is it just for small residential loads? Also, what is the degradation rate of these molecules after a few hundred cycles?
If this moves out of the lab, we need to see if it qualifies for existing thermal storage credits. Most policy is still focused on electrons. We need a framework that rewards carbon free heat storage specifically.
