Hydrogen can be burned in combustion engines, similar to traditional fossil fuels. When hydrogen is combusted with oxygen from the air, it produces heat and water vapor as byproducts. The heat generated during the combustion process can be harnessed to produce mechanical work, such as driving a vehicle or generating electricity in power plants.
This application is particularly useful in industries where high-temperature processes are required, such as steel manufacturing and certain heating applications.
One of the most promising and environmentally friendly methods of using hydrogen for energy production is through fuel cells. Fuel cells are electrochemical devices that convert hydrogen and oxygen into electricity and water.
Fuel cells are highly efficient and can produce electricity with almost no emissions if the hydrogen used is produced through renewable energy sources (green hydrogen). This makes fuel cells a vital technology for achieving sustainability goals and transitioning to a low-carbon energy system.
Hydrogen’s ability to be produced using renewable energy and its use in fuel cells makes it a key component in the quest for a clean and sustainable energy future. As the world moves towards reducing greenhouse gas emissions and achieving net zero goals, hydrogen is expected to play an increasingly critical role in energy production and decarbonisation efforts across various sectors.
