All three statements describe potential and current applications of green hydrogen. Green hydrogen, produced using renewable energy, is a versatile energy carrier.
– 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.
Green hydrogen is considered a crucial part of future decarbonization efforts, particularly in hard-to-abate sectors like heavy industry, transport, and long-term energy storage. Its versatility allows for use in various energy applications, either directly, blended, or via conversion technologies like fuel cells.
