In a groundbreaking development, researchers from the Technion Faculty of Materials Science and Engineering have introduced a new technology for producing green hydrogen using renewable energy, as published in Nature Materials.

This innovation offers significant advantages over existing processes and holds the potential to accelerate the adoption of green hydrogen as a sustainable alternative to fossil fuels.

Hydrogen, when used as a fuel, stands out for its potential to reduce greenhouse gas emissions across various sectors, including transportation, material and chemical production, and industrial heating. The traditional method of hydrogen production, however, involves natural gas or coal, emitting substantial carbon dioxide and compromising its environmental benefits.

The newly presented technology, known as E-TAC, addresses key challenges in electrolysis, the process used for green hydrogen production. Unlike conventional electrolysis that requires expensive membranes and sealing components, E-TAC separates hydrogen and oxygen at different stages, eliminating the need for these costly components.

Dr. Hen Dotan and Dr. Avigail Landman, under the guidance of Prof. Avner Rothschild and Prof. Gideon Grader at Technion, spearheaded the development of E-TAC. The innovative technique has the potential to significantly reduce production costs, making green hydrogen more economically competitive.

Green hydrogen, produced through electrolysis powered by renewable sources like wind and solar energy, is crucial for achieving global net-zero emissions—a pivotal target in the fight against climate change. With estimates suggesting that green hydrogen could constitute approximately 10 percent of the global energy market at net zero emissions, the importance of such technological advancements cannot be overstated.

The researchers have collaborated with entrepreneur Talmon Marco to explore commercial applications of E-TAC, marking a step closer to realizing its potential impact on mitigating carbon emissions and replacing environmentally harmful fossil fuels with a clean and sustainable energy alternative.
