Since hydrogen energy, in particular green hydrogen, is increasingly regarded as an important energy carrier in the EU's transition strategies towards a carbon-neutral future, questions concerning both the shape and size of a hydrogen economy need to be asked now. Green hydrogen, it is assumed, can play a significant role in the de-carbonization of high-energy-intensive industries and (some means of) transport as it can both deliver and store a tremendous amount of energy. For hydrogen energy to be sustainable - in other words, for it to be "green" - it must be produced from renewable energy sources, such as wind or solar. However, since at least in some EU countries, such as Germany and the Netherlands, the potential of renewable energy production is limited in the sense that it won't be able to meet projected green hydrogen demands, policymakers are increasingly looking to establish international partnerships to produce green hydrogen outside the EU and import it for national use - with a particular focus on countries in the Global South.
