Aviation sector decarbonization within the hydrogen economy A UAE case study
arxiv(2024)
摘要
The UAE aviation sector is vital for its economy and is forecast to grow
substantially in the coming decades, increasing thereby fuel consumption. At
the same time, the country is committed to cutting greenhouse gas emissions to
mitigate climate change. Liquid green hydrogen is expected to emerge as an
important aviation fuel in the future. The UAE can use its vast solar energy
resources to produce cost-competitive hydrogen at scale, securing so its
aviation fuel supply. This development, however, needs several decades to
materialize. The PV farms needed to produce the electricity for water
electrolysis need yet to be constructed. The infrastructure to produce,
liquify, store and transport hydrogen is yet to unfold. Hydrogen-powered
aircrafts need to yet evolve from the current small scale demonstration
projects to long-haul commercial airplanes. It is realistically by 2050 when
hydrogen gains momentum and by 2070 when it becomes the primary aviation fuel.
This paper details why and how liquid green hydrogen will find its gap as
aviation fuel in the UAE and provides the strategy and policy recommendations
to facilitate this development.
