Ammonia as alternative renewable fuel
Renewable ammonia, a green umbrella for sustainable future.
To move from large centralised ammonia plants with high-energy consumption and CO2 emissions to ammonia as a renewable fuel, it is necessary to switch to smaller scale decentralised ammonia production facilities with electricity produced from renewable sources such as wind turbines and solar photo-voltaic cells. Observing the highly efficient nitrogen fixation occurring in nature by bacteria and plants at ambient conditions, we were inspired to explore the electrochemical route to ammonia synthesis.
The reactors for ammonia synthesis will be combining catalytic and magnetic nanoparticles for heating, embedded in high-surface area 3D printed ceramic supports.
Full cell fuel-cells will be assembled and tested for N2 reduction to ammonia in water using new NRR and new OER electrocatalysts at FE>60% and cell potentials of up to 2V.
Plasma-assisted electro-catalytic reactor
CPlasma will activate nitrogen molecules and shift selectivity towards ammonia synthesis at higher current densities to improve the overall production rate.
