Abstract
The present disclosure relates to hydrogen pumping systems for pumping hydrogen from a fuel tank (where the hydrogen is stored as liquid hydrogen LH2) to a power generation device at which the hydrogen is used as fuel. The pumping systems include features providing system redundancy, effective heat exchange for warming the hydrogen, gas turbine air bleed cooling, component cooling and removal of hydrogen gas.
Claims21
(canceled)
A fuel system for supplying hydrogen to a gas turbine engine, the fuel system comprising:
- a tank for containing hydrogen in a liquid form;
- a fuel line that extends from the tank to the gas turbine engine;
- a pump for pumping the hydrogen through the fuel line in a direction from the tank toward the gas turbine engine;
- a heat exchanger positioned along the fuel line between the pump and the gas turbine engine for heating the hydrogen pumped through the heat exchanger by the pump;
- wherein the heat exchanger is configured to transfer heat from bleed air sourced from a compressor of the gas turbine engine to the hydrogen in the fuel line.
A fuel system for supplying hydrogen to a gas turbine engine, the fuel system comprising:
- a tank for containing hydrogen in a liquid form;
- a fuel line that extends from the tank to the gas turbine engine;
- a pump for pumping the hydrogen through the fuel line in a direction from the tank toward the gas turbine engine;
- a heat exchanger positioned along the fuel line between the pump and the gas turbine engine for heating the hydrogen pumped through the heat exchanger by the pump;
- and
- a valve positioned between the heat exchanger and the gas turbine engine for controlling a flow of hydrogen to an injector of a combustor of the gas turbine engine.
A fuel system for supplying hydrogen to a power generation device, the fuel system comprising:
- a tank for containing hydrogen in a liquid form;
- a fuel line that extends from the tank to the power generation device;
- a pump for pumping the hydrogen through the fuel line in a direction from the tank toward the power generation device;
- and
- first and second electric motors for powering the pump, the first and second electric motors being mechanically coupled to an input shaft of the pump by a gear set.
