On 8th July, the EU announced its hydrogen strategy as a priority within the Green Recovery Plan. Clean hydrogen will be a key tool for cutting greenhouse gas emissions in sectors that are highly dependent on fossil fuels. The European Commission aims to achieve 40GW of renewable hydrogen capacity by 2030, which is an ambitious target as it represents 2.7 times the estimated global capacity in that period. Even so, it is only 5% of the global capacity that would be needed to achieve the Paris agreement objectives.
