  • Patent number: 10829369
    Abstract: A system for distribution of hydrogen gas in a metal hydride reactor is disclosed. The system comprises a hydrogen distribution conduit positioned within a metal tube so as to define an annular space between the hydrogen distribution conduit and the outer metal tube. The hydrogen distribution conduit provides a flow passage for the hydrogen gas. A metal sponge matrix containing hydrogen-storing metal powder or hydrogen-storing alloy powder is filled in the annular space. The system provides a more uniform distribution of hydrogen across the particles of the hydrogen-storing metal/alloy powder, provides mechanical support to the hydrogen distribution conduit, improves the thermal conductivity of the powdered metal/alloy bed and reduces the size and production cost of the reactor.

  • Patent number: 10829384
    Abstract: Oxycombustion systems and oxycombustion methods include thermally integrated ammonia synthesis. The oxycombustion systems may include an air separation unit that separates air into an oxygen stream and a nitrogen stream. An ammonia synthesis unit synthesizes ammonia from a hydrogen feed and the nitrogen stream to form a crude ammonia stream. An ammonia separation unit condenses the crude ammonia stream and separates the ammonia from any unreacted nitrogen and hydrogen to form a purified ammonia stream. An oxycombustion reactor combusts a fuel from a fuel feed stream in the presence of the oxygen stream from the air separation unit to generate hot water or steam. At least one thermal integration may be present in the oxycombustion systems and may be chosen from a reactor thermal linkage of the ammonia synthesis unit with the oxycombustion reactor, a separator thermal linkage of the air separation unit with the ammonia separation unit, or both.

  • Patent number: 10781099
    Abstract: An underwater hydrogen generator can include a watertight reaction housing enclosing a metering chamber. The metering chamber can have an upper portion that terminates at a piston opening, and a lower portion that merges into a funnel, which can further terminate at a metering opening. The metering chamber can be filled with an acid accelerator, and the watertight reaction void can be partially filled with NaBH4 in solution. The generator can further include a seawater float valve that can be in fluid communication between the external environment, the metering chamber and the void defined by the reaction housing. The float valve, metering chamber and reaction housing can cooperate to generate hydrogen when said generator is submerged, by allowing seawater to contact both the acid accelerator and the NaBH4. The size of the metering opening can determine the rate at which acid accelerator is added to the NaBH4 solution.
