Paving the Way for Clean Hydrogen Energy

Fast and accurate sensors will be crucial in a sustainable society where hydrogen is an energy carrier. Hydrogen gas is produced by water that is split with the help of electricity from wind power or solar energy. The sensors are needed both when the hydrogen is produced and when it is used, for example in cars powered by a fuel cell. In order to avoid the formation of flammable and explosive gas when hydrogen is mixed with air, the hydrogen sensors need to be able to quickly detect leaks

Paving the Way for Clean Hydrogen Energy

Chalmers University of Technology

Hydrogen is a clean and renewable energy carrier that can power vehicles, with water as the only emission. Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed. Now, researchers from Chalmers University of Technology, Sweden, present the first hy
