Applications of ortho-para hydrogen catalyst

Strategies to recover and minimize boil-off losses during liquid hydrogen storage

“…In o-H 2 isomer, the hydrogen nuclei spin in the parallel direction while the nuclei of the p-H 2 isomer spin in the opposite direction, as illustrated in Figure 3a. ) and heat of conversion from normal to para-hydrogen as a function of temperature (after [45,46]).…”

Recent Advances and Reliable Assessment of Solid‐State Materials for Hydrogen Storage: A Step Forward toward a Sustainable H2 Economy

“…As shown in Figure 14c, at room temperature (300 K), hydrogen exist as a mixture of 75% ortho‐ and 25% para‐hydrogen, while at 20 K, hydrogen exist as 99.8% para‐form. [ 342,343 ]…”

“…As shown in Figure 14c, at room temperature (300 K), hydrogen exist as a mixture of 75% ortho-and 25% para-hydrogen, while at 20 K, hydrogen exist as 99.8% para-form. [342,343] Considering the lower energy state of para-hydrogen, it is theoretically convenient to store hydrogen in the para form. However, www.advsustainsys.com Figure 12.…”
