Columbia Engineers Develop Floating Solar Fuels Rig for Seawater Electrolysis #Hydrogen

Hydrogen is a clean fuel currently used to propel rockets in NASA’s space program and is widely expected to play an important role in a sustainable energy future. Water electrolysis using electricity from solar PV offers a promising route to produce H2 without any associated CO2 emissions. Esposito’s team has now developed a novel photovoltaic-powered electrolysis device that can operate as a stand-alone floating platform. His floating PV-electrolyzer can be thought of as a “solar fuels rig” that bears some resemblance to deep-sea oil rigs, except that it would produce hydrogen fuel from sunlight and water instead of extracting petroleum from beneath the sea floor. The study (DOI: 10.1016/j.ijhydene.2017.11.086), “Floating Membraneless PV-Electrolyzer Based on Buoyancy-Driven Product Separation ,” was published recently by International Journal of Hydrogen Energy . The res...
