EGP to Test use of Bacteria to reduce H2S Emissions from Geothermal Plants
The bacterial consortium is able to produce hydrogen from the demolition of H2S in a more efficient and less expensive way compared to alternative methods.
Italian multinational Enel Green Power (EGP) is considering testing the use of a bacterial consortium to reduce Hydrogen Sulphide (H2S) emissions from geothermal plants.
The bacterial consortium is able to produce hydrogen from the demolition of H2S in a more efficient and much less expensive way compared to alternative methods.
The idea was entered in EGP's challenge launched in September 2017 through the Open Innovability online platform to search for innovative solutions to reduce the emission of hydrogen sulphide, while avoiding or reducing the use of soda, in the geothermal plants and to make the Mercury and Sulferized Hydrogen Reduction (AMIS) systems in EGP geothermal plants more effective.
The winning idea presented by Luigia Lona involves a change in the last stage of the AMIS cycle, where soda is used to regulate the level of acidity in the liquid solution coming from the H2S reduction process. Specifically, the change involves halving the entry of soda in the scrubber and introducing a system that allows for the optimization of the quantity of soda consumed for different sections.
The winner, Luigia Lona, is a researcher, entrepreneur and scout for innovative solutions and has a degree in biological sciences with a specialization in bimolecular sciences, and a research doctorate on methods of desulphurization from Enea's biomass laboratory. On top of having her idea tested, Luigia will get the 15,000-euro prize for her idea.
