Ad 1.
The use of surplus power from offshore wind will be used for production of “green” hydrogen that can be blended with “gray” hydrogen and used in Haber-Bosch process for ammonia synthesis. Source of nitrogen can be either cryogenic (low-cost, but unflexible) or membrane (high-cost, but flexible) separation. Produced ammonia will be partly “green”, or decarbonised. Ammonia can be stored with relatively low cost and used afterwards.
This will be modelled in Matlab or Python. We can provide Python model which can be translated to Matlab.

Ad. 2. Ammonia can be used for decarbonisation of:
energy sector via direct combustion in gas turbine (after blending with additional H2) – likely to happen
energy sector as an energy carrier for DAFC (direct ammonia fuel cell) – only prototype of DAFC exists
final consumption sector – agriculture (as fertilizer) – could happen
final consumption sector – transport (for combustion in internal combustion engines) – not likely to occur, may be skipped
final consumption sector – transport (as an energy carrier for DAFC or PEM fuel cells) – could happen.
Options will be tested in EnergyPLAN, a model that simulates national energy systems.
