Direct Air Capture (DAC) is recognized as the ‘gold standard’ for CO2 removal due to its durability and scalability. However, its widespread adoption has been hindered by high energy needs and limited availability of renewable energy. Geothermal energy, which provides both heat and electricity, offers a practical solution. This project will assess the impacts of Hydrogen Sulphide on DAC adsorbents, optimizing performance, thus paving the way for cost-effective deployment.
