Power-to-gas

Power-to-gas is a process that converts surplus electricity—especially from renewable sources like wind or solar—into stored fuel, typically hydrogen or methane. This is done through electrolysis, where electricity splits water into hydrogen and oxygen. The produced hydrogen can be stored, transported, or used directly as clean fuel, helping to balance energy supply and demand. When renewable energy generation exceeds immediate needs, power-to-gas provides a way to store excess energy and reduce reliance on fossil fuels, contributing to a more flexible and sustainable energy system.
