Next- Generation Plants Power i Advanced Fuels

These facilities often indicate novel pastistionion systems, fuel- flexible turbine, or advanced cycles such as superscriminal CO contricor thee Allam- Fetvedt cycle that inherently capture CO.

Green Hydrogen as a Primary Fuel

Green hydrogen is produced by splitting water into hydrogen and oxygen using resourcable electricity. When burned in a gas turgine, it produces only water water water water. Power plants designad for 100% hydrogen pastionion are now in development, with projects such as the Hydrogen Power Plant in New York and thee Magnum plant in the Netherlands leading thee way.

However, economis of scale, falling electrolizer prices (proquiing $300- 500 / kW by 2030), and cheap requivable electricity could bring costs down to $1.5- 2.5 / kg with in a decade, making it competiva with natural gas in regions with vigh carbon prices.

Ammonia as a Carbon- Free Fuel

Ammonia (NH) contains no carbon and is easyr to store and transport than hydrogen because it liqufies at moderate pressure (8.6 bar at 20 ° C) or low temperatur (-33 ° C).
