Natural gas as an energy source for fuel cells


Natural gas is a fossil fuel that primarily consists of methane. Methane is a hydrocarbon with a high energy content that causes the least carbon dioxide emissions among all fossil fuels. This hydrocarbon is broken down into hydrogen and carbon monoxide and converted into electricity in the fuel cell system. There is already a comprehensive infrastructure set in place for producing and using natural gas. While natural gas resources are vast, they are, however, ultimately finite. 


Biomethane or organic natural gas is produced from organic gas, which, in turn, is not produced from fossil fuels but by fermenting biogenic substances, (e.g., from organic waste).


Current developments in wind gas aim to generate hydrogen in an electrolyser using fluctuating energy sources, such as wind turbines and using excess electricity to convert it into methane. The resulting methane can be stored and transported in the existing infrastructure. That is why wind gas is referred to as storage gas.
