To achieve the GHG reduction goals, hydrogen, Natural Gas and ammonia are considered as marine fuel in their liquefied form. Hydrogen and Natural Gas need to be liquified at cryogenic temperatures, whereas ammonia can be liquefied through the application of moderate pressure, approximately 10 bar, or through the reduction of temperature to approximately -33 °C. LNG is already employed in...
As hydrogen continues to gain adoption as a global energy carrier, a renewed focus on hydrogen liquefaction technologies has emerged. The hydrogen liquefaction process requires extremely pure hydrogen feed gas to prevent the freeze out of impurities which can damage equipment. This study investigates the impact of temperature on the nitrogen adsorption performance of three widely used...
Hydrogen is widely regarded as an ideal clean and renewable energy source. Liquid hydrogen (LH2) is often used for storage due to its high energy density and suitability for various applications. However, in the event of an accidental LH2 release, the liquid rapidly and extensively evaporates into gaseous hydrogen, posing significant safety risks. To address these concerns, a study utilizing...
Investments in the hydrogen economy, including the 7-billion USD Hydrogen Hub initiative, are poised to greatly expand employment in the hydrogen sector. Training and education at all levels will be essential for ensuring hydrogen fuel maintains an excellent safety record amid expanding use. However, few cryogenic hydrogen safety programs are available and little to no data on program...
