The European Union (EU) has set itself a long-term goal of reducing greenhouse gases (GHG) emissions by 80-95% by 2050 in comparison to 1990. Hence, the use of renewable energies is mandatory in order to achieve this goal. In order to avoid this problem, it is essential to move our energy matrix towards to a sustainable and renewable one. Hydrogen is anticipated to be one of the best candidates for carbon-free fuels. It is a clean fuel, and its burning causes no harmful emissions. However, the cost to produce, storage and compress it is very high. Ammonia appears to be a potential solution as a hydrogen storage.
