Explanation:
Green hydrogen can be used as a fuel for internal combustion engines, but it requires modifications to the engine design to accommodate hydrogen fuel. It is not commonly used directly as a fuel for internal combustion engines due to infrastructure limitations and the availability of more established alternatives.
Green hydrogen can indeed be blended with natural gas and used as a fuel for heat or power generation. This blending allows for the gradual integration of hydrogen into existing natural gas infrastructure, reducing carbon emissions.
Green hydrogen is commonly used in hydrogen fuel cells to generate electricity and power electric vehicles. Fuel cells combine hydrogen with oxygen from the air to produce electricity, with water as the only byproduct.
