Hydrogen fuel system

This invention describes a vehicle fuel system that primarily uses liquid hydrogen. When the engine needs a sudden burst of power, or more fuel than the liquid hydrogen pump can supply, the system automatically supplements the liquid hydrogen with stored gaseous hydrogen from a separate tank or a buffer tank, ensuring the engine always gets the fuel it needs.

Why it matters: Since 2022, advancements in real-time control systems and sensor technology for hydrogen fuel delivery have made the precise blending and rapid switching between liquid and gaseous hydrogen sources more feasible and efficient for dynamic engine demands.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedLiquid hydrogen handling, high-pressure gas storage, control electronics
