Hydrogen fuel is one of the most promising alternatives to fossil fuels with virtually zero emissions of harmful combustion products.The problem is that hydrogen (H2) are obtained as a result of a process known as “methane evaporation”, in which, alas, CO2 is the main factor of global warming .

Daniel Esposito, associate professor of the Chemical Engineering Department of the School of Engineering and Applied Sciences at Columbia University, together with He developed a technology for the electrolysis of water (separation into hydrogen and oxygen O2) without the release of CO2, and the pilot plant, called a “floating photovoltaic cell,” would be a prototype of equipment for the production of hydrogen on an industrial scale. floating oil platform.

The device is a unique configuration of electrodes that separate and collect hydrogen and oxygen, taking into account the buoyancy of their bubbles in water. The system does not require pumping the liquid inside the device, resulting in a clean 99% hydrogen.

Esposito's laboratory facility is not yet ready for testing in the marine environment. However, in the future, scientists intend to improve its design and make it more efficient and productive.

“There are many possible technological solutions in the field of future energy, although so far only in theory,” explains Daniel Esposito. “Our task is to create scalable and economical technologies that convert sunlight into useful energy that can be stored in the dark.”
