Understanding Clean Renewable Hydrogen
Clean renewable hydrogen is one of the most abundant elements on Earth and has the highest energy content of any common fuel by weight, but it rarely exists alone, therefore it is produced by extracting it from its compound. When combusted, hydrogen produces water vapor, not greenhouse gas emissions. It can be safely produced, transported, stored, and blended into the existing gas grid to help decarbonize the pipelines. This can require a lot of energy and resources which is why hydrogen technology must be improved to lower the costs involved with using it.
Hydrogen has been safely used for decades in aeronautics to fuel space exploration and in the industrial sector to process food, manufacture electronics, and make glass and metal. Some processes can produce greenhouse gas emissions so it is important to focus on technology that will focus on low to zero emissions. For example, hydrogen can be renewable or decarbonized if produced using renewable or carbon free electricity such electricity produced from wind turbines.
