Technical FAQs 4

How does a sulphuric acid plant work?

The resulting gas is sulphur dioxide (SO 2 ), which can be fed into a conventional sulphuric acid plant to produce sulphuric acid and large amounts of heat. This heat then drives a steam turbine that generates additional electricity. The cycle can then begin again with the decomposition of the sulphuric acid.

Could sulfur be a suitable storage material for base-load electricity production?

“Solar power plants effectively capture process heat and sulfur might be a suitable storage material to use this power for base-load electricity production,” Professor Dimosthenis Trimis of KIT’s Engler-Bunte Institute says. Sulfur and sulfuric acid are used in many industrial applications.

Why is sulphur used in power plants?

Why sulphur? Sulphur can be used as fuel for gas or steam turbines in power plants. In addition, sulphur is a promising energy storage medium for solar thermal power plants. Combining these two power plant technologies is a further step towards climate-neutral electricity production.

How sulphuric acid is converted into fuel?

This process is based on a chemical cycle. It involves burning sulphur in special power plant turbines and converting the exhaust gases into sulphuric acid. Using solar energy, the sulphuric acid can then be converted back into pure sulphur, without producing carbon dioxide; this sulphur can then be reused as fuel. Why sulphur?
