Can thermal energy be stored as chemical energy?

Thermal energy from the sun can be stored as chemical energy in a process called solar thermochemical energy storage (TCES). The thermal energy is used to drive a reversible endothermic chemical reaction, storing the energy as chemical potential.

What is concentrating solar power (CSP)?

Incorporating storage into concentrating solar power (CSP) systems enables dispatchable generation, whereby utilities produce power to match demand. This efficient method of power production overcomes intermittency challenges faced by other forms of renewable energy production. It also reduces the cost of solar energy through higher utilization.

Is solar-to-chemical energy conversion a viable solution?

Nature Reviews Materials 6, 168–190 (2021) Cite this article Solar-to-chemical energy conversion for the generation of high-energy chemicals is one of the most viable solutions to the quest for sustainable energy resources.

Can thermochemical heat storage be used in next-generation power plants?

Sensible heat storage has been already incorporated to commercial CSP plants. However, because of its potentially higher energy storage density, thermochemical heat storage (TCS) systems emerge as an attractive alternative for the design of next-generation power plants, which are expected to operate at higher temperatures.

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.

Can solar energy reduce CO2?

Photocatalytic reduction of CO 2 by using solar energy is emergent not only for environmental concerns but also production of suitable chemicals and fuels. Metal-organic frameworks have been considered in forefront in photocatalysis due to porous and adjustable structure.
