Design and Analysis of an Offshore Wind Power to Ammonia Production System in Nova Scotia

Green ammonia has potential as a zero-emissions energy vector in applications such storage, transmission and distribution, transportation. Renewable offshore wind been proposed to power its production. This paper designed analyzed an on-land small-scale power-to-ammonia (P2A) production system with target nominal output of 15 tonnes per day, which will use 8 MW turbine off the coast Nova Scotia, Canada main source. The P2A consists reverse osmosis system, proton exchange membrane (PEM) electrolyser, hydrogen storage tank, nitrogen generator, set compressors heat exchangers, autothermal Haber-Bosch reactor, tank. uses electrical grid back-up for when is insufficient process assumes steady state. Two scenarios were Scenario 1 producing state 2 being one that switched rates whenever speeds low 55% capacity. results show connected significant emissions both scenarios, larger than traditional fossil-fuel based production, using provinces like even if it just during generation. levelized cost (LCOA) was calculated be at least 2323 CAD tonne−1 not competitive this small scale. Scaling up whole reducing reliance on electricity grid, increasing service life, decreasing windfarm costs could reduce LCOA make more competitive.
