- Hydrogen can be used as a direct fuel in modified or specially designed internal combustion engines. - Hydrogen can be blended with natural gas (methane) and used in existing gas infrastructure and appliances for heating or power generation, reducing the carbon intensity of the natural gas stream. - Hydrogen is a key fuel for hydrogen fuel cells, which electrochemically convert hydrogen and oxygen into electricity, water, and heat, commonly used in fuel cell vehicles and stationary power generation.
With reference to green hydrogen, consider the following statements: 1. It can be used directly as a fuel for internal combustion. 2. It can be blended with natural gas and used as fuel for heat or power generation. 3. It can be used in the hydrogen fuel cell to run vehicles. How many of the above statements are correct?
