6 FAQs about [Thermochemical energy storage ppt]

What are the principles of thermochemical energy storage?

Principles of Thermochemical Energy Storage C + heat A + B In this reaction, a thermochemical material (C) absorbs energy and is converted chemically into two components (A and B), which can be stored separately. The reverse reaction occurs when materials A and B are combined together and C is formed.

Can thermal energy be stored in a heat storage media?

Thermal energy (i.e. heat and cold) can be stored as sensible heat in heat stor-age media, as latent heat associated with phase change materials (PCMs) or as thermo-chemical energy associated with chemical reactions (i.e. thermo-chemical storage) at operation temperatures ranging from -40°C to above 400°C.

How much energy does a thermochemical storage system store?

In most cases, storage is based on a solid/liquid phase change with energy densities on the order of 100 kWh/ m3 (e.g. ice). Thermo-chemical storage (TCS) systems can reach storage ca-pacities of up to 250 kWh/t with operation temperatures of more than 300°C and efi ciencies from 75% to nearly 100%.

Why does thermochemical storage have a higher energy density?

Thermochemical storage has inherently higher energy density than latent- or sensible-heat storage schemes because, in addition to sensible heat, energy is stored as chemical potential.

What is thermochemical TES?

Thermochemical TES is an emerging method with the potential for high energy density storage. Where space is limited, therefore, thermochemical TES has the highest potential to achieve the required compact thermal energy storage. Thermochemical TES is presently undergoing research and experimentation.

Why are thermochemical storage materials so expensive?

Materials for thermo-chemical storage (TCS) are also expensive as they have to be prepared (e.g. pelletised or layered over supporting structures). Also expensive are the containers and the auxiliary TCS equipment for both heat and mass transfer during energy charging and discharging.
