Currently 50 million tonnes of Hydrogen are produced globally every year. It is predicted that the production will increase substantially over the coming decades. Currently 95-96% of global Hydrogen production is obtained from fossil fuels, which produces 90-99% purity Hydrogen with greenhouse gases (GHGs) as a by-product.
Water electrolysis represents only 4-5% of global Hydrogen production. The process involves passing an electrical current through water, to split water molecules into Hydrogen and Oxygen. The Hydrogen produced is very pure (>99.99%) and therefore will not poison the highly expensive platinum catalyst in Proton Exchange Membrane Fuel Cells (PEMFCs).
Dan’s PhD primarily focuses on the design, build and testing of electrolysers for alkaline and PEM technologies. These electrolysers can then be incorporated into much larger systems for application on a much larger scale. Systems will be designed, built and tested for stationary and mobile applications.
These systems can incorporate renewable resources such as solar and wind energy to provide electrical energy to electrolysers which produces no (GHG) emissions. Since water electrolysis produces no GHG emissions, ‘Green’ Hydrogen is produced since it has a zero carbon footprint.
