Clean Fuel Alternatives Through Green Hydrogen
Clean Fuel Alternatives: Green hydrogen is positioned as a substitute for diesel, natural gas, and coal in heavy transport and industries. It helps lower carbon intensity in energy systems.
Green hydrogen itself is a critical Clean Fuel Alternative, but it is also a versatile precursor for a range of hydrogen-derived clean fuels, often referred to as e-fuels or Renewable Fuels of Non-Biological Origin (RFNBOs). These alternatives are essential for decarbonizing sectors where direct electrification or pure hydrogen use is impractical. The most prominent hydrogen-derived clean fuels include Green Ammonia and Green Methanol.
Green Ammonia is produced by combining green hydrogen with nitrogen from the air. It is a vital clean fuel for the maritime shipping industry and is also a low-carbon fertilizer feedstock. Crucially, ammonia is easier and cheaper to transport and store than liquid hydrogen, making it an excellent hydrogen carrier for international trade. Similarly, Green Methanol (e-methanol) is synthesized from green hydrogen and captured carbon dioxide. It serves as a drop-in fuel for parts of the shipping sector and is a key chemical building block for plastics and other materials.
Its market acceptance is growing rapidly, particularly in the maritime industry, where major container shipping lines are ordering dual-fuel vessels. For aviation, green hydrogen is used to produce Sustainable Aviation Fuel (SAF) via the Power-to-Liquids (PtL) route. While adoption is currently limited by the high production cost of these e-fuels, market acceptance is rapidly accelerating, driven by strict regulatory mandates (like the EU's ReFuelEU Aviation initiative) and the clear need for zero-carbon liquid fuels in hard-to-abate transport sectors. These clean fuel alternatives effectively expand green hydrogen's utility beyond a simple gas, enabling the decarbonization of the global liquid fuels supply chain.
