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.

虽然氢将在全球脱碳中发挥主导作用，但在其可靠的储存和运输方法方面仍然存在重大挑战。由于其高能量密度和氢纯度，氢液化已经成为这方面有前途的方法，但目前过于昂贵。 在这个项目中，我们将利用氢的特殊自旋物理学，通过在再气化后提供可控制冷（所谓的“冷能”）来降低再气化成本。 特别是，我们将测量、优化和利用高度吸热的催化转化帕拉氢到邻氢，这可以在方便的温度下提供高达525 kJ/kg的冷却。
