New noble-metal-free electrocatalyst decreases the energy required to generate hydrogen gas from water

As a combustible fuel, the burning of hydrogen gas does not contribute to global warming. Today, the majority of hydrogen gas is generated from fossil fuels, however, and this process releases greenhouse gases into the atmosphere. Generating hydrogen gas from clean sources, such as the splitting of water molecules with electricity through electrolysis, is important to achieving future carbon neutrality, but current methods are inefficient and limit the commercial practicality of hydrogen-based technologies.
