Hydrogen exists as a gas at room temperature, so the pumps have to operate cold to prevent the liquid from boiling. Inherently, the system still has boil-off gas that gets wasted. So what’s the ...

For example, due to how cold liquid hydrogen is, engineering a durable fuel pump is incredibly difficult. In fact, during the Fuji race, Toyota's team had to replace the fuel pump twice ...

The station uses a new type of pump that raises the pressure of liquid hydrogen, turning it into supercooled liquid hydrogen, according to Daimler. This allows for higher storage density ...

Liquid hydrogen has almost twice the energy density ... From the tank, a high-pressure pump injects the fuel into a vaporizer, where it becomes a gas again and then heads to the engine to ...

It's a surprisingly simple facility with a cryogenic hydrogen storage tank with a capacity of 4,000 kg, and pump for transferring the liquid from the storage tank to the truck's tanks, and ...

Liquid hydrogen’s journey into a cylinder head is also somewhat more complex than gaseous hydrogen’s. Fuel pumps are a particularly thorny issue: Hydrogen’s small molecular size and the ...

Credit: Rolls-Royce Rolls-Royce has begun tests of aerospace-rated pumps able to handle hydrogen in its cryogenic liquid state. The effort is part of the engine-maker’s growing research into the ...

Rolls-Royce has embarked on cryogenic tests to pressurise liquid hydrogen and pump it into an engine’s combustion chamber, as part of its effort to develop hydrogen-based propulsion for future ...

Kurita worked with the stakeholders to design, deliver and implement an integrated treatment system to ensure a continuous ...
