Responding to commercial space launch vehicle providers developing rocket engines fueled by liquefied natural gas (LNG) in recent years, NASA began exploring the so-called “weathering” of the cryogenic mixture—the preferential evaporation of lower boiling point constituents over time, leading to a change in the bulk liquid composition. Due to relatively long delays between launches...
The transition of the energy market to sustainable resources demands a variety of energy storage technologies. Existing systems propose energy storage from kWh to GWh levels, each with its strengths and limitations. The presented research proposes a novel energy storage method (patent pending) of cryo-adsorbed hydrogen energy storage (CAHES), aiming for large scale applications, in order of up...
Liquid hydrogen-fueled electric aircraft is a promising approach to achieving zero-emission aviation goals, particularly when combined with high-temperature superconducting (HTS) power device technology. Liquid hydrogen serves as an energy source and a cryogenic heat sink, enabling multiple high power-density superconducting devices and conventional components onboard the aircraft. Liquid...
The increased demand for hydrogen as an energy vector and storage medium drives the need for higher liquefaction capacities. However, the design of the necessary ortho-parahydrogen converters has long been associated with substantial uncertainty. Until now, the only available data on the activity of the standard catalyst, hydrous ferric oxide—commercially available as the “Ionex-Type O-P...
As the demand for climate-friendly mobility solutions increases, hydrogen stands out as a key enabler, especially in heavy-duty sectors like transportation and aviation. Liquid hydrogen, with its high energy density, holds significant promise for these industries. Many studies focus on the application of liquid hydrogen in these sectors. However, also the supporting infrastructure – including...
Evaluating the boil-off rate (BOR) of liquefied natural gas (LNG) transported in cargo containment systems is crucial for assessing system performance. Research has focused not only on static cryogenic storage tanks but also on tanks under sloshing conditions. Numerical simulations have demonstrated that sloshing significantly affects the thermophysical processes and boil-off gas (BOG)...
The growing demand for cleaner and more efficient fuel solutions in the maritime industry has caused an increased adoption of liquefied natural gas (LNG) as a primary fuel source. To support this transition, a high-performance submerged electrical centrifugal LNG fuel pump has been developed to meet the stringent operational and safety requirements of this industry. The design of a two-stage...
