Scientists create hydrogen with no direct CO2 emissions at source

Scientists have developed a new way to create hydrogen without releasing CO₂ at the source. The process uses bioethanol from agricultural waste and reacts it with water at 270°C. A special catalyst enables this reaction, producing hydrogen and valuable acetic acid, which is used in food preservation, cleaning, and medicine.

Traditional methods require high temperatures and release large amounts of CO₂. This new approach lowers energy use and supports a cleaner hydrogen economy. Researchers from Peking University and Cardiff University believe it could help replace fossil fuels in chemical production.

Hydrogen is a key energy source for a sustainable future, but 96% of current production still relies on fossil fuels, leading to high carbon emissions. The new process allows for hydrogen production without these emissions, making it a promising alternative.

The study builds on years of research into catalysts that improve hydrogen production. The co-production of acetic acid also increases economic benefits, making the method more practical for industries. Scientists see this breakthrough as a step toward carbon neutrality and a more sustainable chemical industry. Their findings are published in Science, highlighting its potential impact on global energy goals.
