Scientists have developed a hydrogen sensor that could accelerate the transition to clean hydrogen energy. As the world transitions away from fossil fuels, hydrogen is considered a key player to the transition to cleaner energy. However, the clear, odorless and highly flammable gas is hard to detect using human senses and poses a challenge for its safe deployment.<\/p>\n

The sensor, developed by a scientist at The University of Manchester, can reliably detect even the tiniest amounts of hydrogen in seconds. It is small, affordable, and energy-efficient\u2014and its results outperform portable commercial hydrogen detectors.<\/p>\n

The research, in collaboration with the King Abdullah University of Science<\/a> and Technology<\/a> (KAUST) in Saudi Arabia, was published<\/a> today in the journal Nature Electronics<\/i>.<\/p>\n

“This sensor could offer a breakthrough in hydrogen safety technology. By combining affordability, reliability, and high performance, it has the potential to transform how we handle hydrogen across industries, homes, and transportation. I hope our organic sensor will help build trust in emerging hydrogen technologies, making them more accessible and safer for everyone,” says Thomas Anthopoulos.<\/p>\n

The operation of the new organic semiconductor sensor relies on a process known as “p-doping,” where oxygen molecules increase the concentration of positive electrical charges in the active material. When hydrogen is present, it reacts with the oxygen, reversing this effect and causing a rapid drop in electrical current. This change is fast and reversible at room temperature up to 120\u00b0C.<\/p>\n

The sensor was tested in various real-world scenarios, including detecting leaks from pipes, monitoring hydrogen diffusion in closed rooms following an abrupt release, and even being mounted on a drone for airborne leak detection. In all cases, the sensor proved faster than portable commercial detectors, demonstrating its potential for widespread use in homes, industries, and transport networks.<\/p>\n

Importantly, the sensor can be made ultra-thin and flexible and could also be integrated into smart devices, enabling continuous distributed monitoring of hydrogen systems in real time.<\/p>\n

The team is now focusing on advancing the sensor further while assessing its long-term stability in different sensing scenarios.<\/p>\n
