Abstract
Abstract Ammonia is a dense energy carrier with high energy density and established supply chain for transport, and storage of hydrogen. Ammonia is a common commodity used in the fertiliser and chemical sector and has a potential to become an affordable and sustainable energy carrier to meet growing demand for industrial decarbonisation. The transport of hydrogen over long distances require an efficient and cost competitive carrier. Potential options for hydrogen carrier are ammonia, liquid organic hydrogen carrier (LOHC), liquid hydrogen, compressed hydrogen, and methanol. This paper describes an innovative ceramics-based solid oxide fuel cell technology for conversion of ammonia into fossil fuel parity energy at a thermal efficiency of 85%. The technology is based on proton conducting ceramics (PCC) electrochemical pathway which eliminates NOx emissions by design and ammonia slippage by catalyst performance and reactor design. The technology has been developed over 7 years, between 2016 to 2022, and the ammonia utilisation capabilities has been proven through demonstrations conducted for O&G and industrial companies. The technology uses low-cost and widely available ceramics-based catalyst. The technology is particularly suited for industrial decarbonisation because of the ability to yield high efficiency and the ability to produce low-cost heat at 700C and hydrogen as byproducts.
