Catalyst That Makes Hydrogen Gas Breaks Speed Record
Looking to nature for their muse, researchers at PNNL have used a common protein to guide the design of a material that can make energy-storing hydrogen gas.
Adding Natural Elements to Synthetic Catalysts Speeds Hydrogen Production
By grafting features analogous to those in Mother Nature's catalysts onto a synthetic catalyst, scientists at PNNL created a hydrogen production catalyst that is 40% faster than the unmodified catalyst.
PDX and PNNL Explore Hydrogen Fueling for Hazard Resilience
PDX, PNNL, and Sandia National Laboratories are exploring the feasibility of hydrogen fuel for the PDX bus fleet—an idea that could have novel benefits for hazard resilience.
New Catalyst Dives into Water to Produce Hydrogen
Few catalysts are energy efficient, highly active, stable and operate in water, but a nickel-based catalyst designed at the Center for Molecular Electrocatalysis at PNNL quickly produces hydrogen molecules in solutions with 75 percent water
Wet Aluminum Hydroxide and Oxyhydroxide Particles Release Hydrogen When Irradiated
Vitrifying nuclear waste for storage is complicated by aluminum and understanding this behavior is vital. Research suggests that upon radiolysis, the properties of humid aluminum particles do not change substantially but hydrogen is formed.
ACTIVE MAGNETIC REGENERATIVE PROCESSS AND SYSTEMS EMPLOYING HYDROGEN AS HEAT TRANSFER FLUID AND PROCESS
A process for liquefying a hydrogen process gas comprising: introducing a hydrogen heat transfer fluid into an active magnetic regenerative refrigerator apparatus that comprises (i) a high magnetic field section in which the hydrogen heat transfer fluid flows from a cold side to a hot side through at least one magnetized bed of at least one magnetic refrigerant, (ii) a first no heat transfer fluid flow section in which the bed is demagnetized, (iii) a low magnetic field or demagnetized section in which the hydrogen heat transfer fluid flows from a hot side to a cold side through the demagnetized bed, and (iv) a second no heat transfer fluid flow section in which the bed is magnetized; continuously introducing the hydrogen heat transfer fluid from the cold side of the low magnetic field or demagnetized section into the cold side of the high magnetic field section; continuously diverting a portion of the hydrogen heat transfer fluid flowing from the cold side of the low magnetic field or demagnetized section into an expander; and isenthalpically expanding the diverted portion of the hydrogen heat transfer fluid to produce liquefied hydrogen.
