6 FAQs about [Chemical reaction thermal energy storage]

How does thermochemical heat storage work?

Thermochemical heat storage works on the notion that all chemical reactions either absorb or release heat; hence, a reversible process that absorbs heat while running in one way would release heat when running in the other direction. Thermochemical energy storage stores energy by using a high-energy chemical process.

How long can heat be stored in a thermochemical reaction?

Unlike sensible or latent heat storage, which stores heat in a single material, in a thermochemical reaction heat can be stored indefinitely by keeping compounds B and C separate. Figure 1.
