Heriot-Watt University scientists have successfully used wastewater from the distilling industry to produce green hydrogen.
Dr Sudhagar Pitchaimuthu and PhD student, Michael Walsh, developed a nanoscale material – dubbed a nickel selenide – to allow distillery wastewater to replace fresh water in the production of green hydrogen.
The nickel selenide treats the wastewater and, in this project, produced similar or slightly higher quantities of green hydrogen from the wastewater, compared to fresh water results. The research has been published in the Royal Society of Chemistry journal, Sustainable Energy & Fuels, in a paper authored by Walsh.
