While hydrogen is set to play a leading role in global decarbonisation, significant challenges remain regarding methods for its reliable storage and transportation. Hydrogen liquefaction has emerged as a promising approach in this regard due to its high energy density and hydrogen purity, but is currently prohibitively expensive. In this project we will exploit the peculiar spin physics of hydrogen to alleviate liquefactions costs through the provision of controllable refrigeration (so-called 'cold energy') following regasification. In particular we will measure, optimise and exploit the highly endothermic catalysed conversion of para- to ortho- hydrogen, which can provide up to 525 kJ/kg of cooling at convenient temperatures.

尽管氢将在全球脱碳中发挥主导作用，但其可靠的储存和运输方法仍然面临重大挑战。由于其高能量密度和氢气纯度，氢气液化已成为这方面一种有前途的方法，但目前价格昂贵。 在这个项目中，我们将利用氢独特的自旋物理学，通过在再气化后提供可控制冷（所谓的“冷能”）来降低液化成本。 特别是，我们将测量、优化和开发对氢至正氢的高吸热催化转化，该转化可以在方便的温度下提供高达 525 kJ/kg 的冷却。
