In both cases there will be challenges of public acceptability, even if some perceptions do not reflect the real risks involved. 2. Low-carbon production and use of hydrogen and ammonia. Hydrogen and ammonia ofer opportunities to provide low carbon energy and help reach the target of net-zero emissions by 2050.
Ammonia, a molecule that is gaining more interest as a fueling vector, has been considered as a candidate to power transport, produce energy, and support heating applications for decades. However, the particular characteristics of the molecule always made it a chemical with low, if any, benefit once compared to conventional fossil fuels.
Ammonia is of interest in energy storage, as a zero-carbon fuel and as a hydrogen carrier [54]. A key benefit is its established infrastructure for production, storage, and distribution.
Diagram of ammonia-hydrogen-electricity cogeneration system. In this simulation, the heat source power is set at 250 MW, which results in the production of 538 kmol/h of NH 3.
