A solar reactor that operates on air, CONSTISOL, has successfully been tested by researchers of international solar thermal energy so as to come up with a solar fuel such as hydrogen and to enable smooth running of it during night or day. CONSTISOL makes use of concentrated solar power (CSP) that comprises storage of thermal energy.
Limitless Supply of Sunlight to Fuel the Process
Solar fuels come with zero carbon fuels such as hydrogen and it comes with a promise to not to emit climate-damaging carbon that is utilizes produce hydrogen from natural gas in the today’s world. As such, better and improved solar reactors are the key to the future that would have 100% clean energy.
Rather than burning fossil fuel that is required for the generation of heat and to drive the process of the thermal chemistry, for various chemical reactions such as the instance of separating H2 (hydrogen) from H2O, the researchers have been examining different types of reactors that are heated by solar’s thermal form, CSP, which makes use of mirrors so as to concentrate on solar flux on a receiver.
In an effort to achieve zero-carbon heat for thermochemical reactions that would be operational at temperatures as high as 1,500 C, researchers consider that the direct heat from CSP would be more of an efficient clean energy source than any form of electricity from wind or PV.
The unlimited and constant supply of sunlight over the centuries and there would be no adverse effect on the climate when thermochemistry is fuelled by solar energy. The only negative point is the fact that sun goes down in the night.
The said paper was published on Applied Thermal Engineering.
