- Statement 1 is incorrect because geothermal plants, while having lower emissions than fossil fuel plants, can still release some greenhouse gases like carbon dioxide, methane, and hydrogen sulfide (H2S) that are dissolved in the geothermal fluid. The claim that they "do not release any" is false. - Statement 2 is correct. Hydrogen sulfide is a toxic gas naturally present in geothermal reservoirs. Geothermal power plants often use emission control systems, such as scrubbers, to remove H2S from the steam or fluid before it is released, meeting environmental regulations. - Statement 3 is correct. Geothermal power plants utilize the Earth's internal heat to produce electricity. This heat source boils water (or another working fluid) to create steam, which drives a turbine. Unlike conventional power plants, they do not rely on burning fossil fuels.
Which of the following statements are correct regarding “Geothermal energy”? 1. Geothermal plants do not release any carbon dioxide and sulphur compounds while generating electricity. 2. Geothermal power plants use scrubbers to remove the hydrogen sulfide naturally found in geothermal reservoirs 3. Geothermal power plants do not burn fuel to generate electricity
