Green Ammonia Production
Conceived as a pan-European asset, The Hub is designed to interconnect with other European Hubs, creating a networked web of resilience. By physically and operationally connecting to European sea-side energy hubs, the Hub helps diversify European Green Hydrogen and Green Ammonia supply routes, reducing reliance on any single geographic area or transport corridor
GREEN AMMONIA HUB
The Hub's technology ecosystem is cutting-edge integration of renewable energy generation, green hydrogen and ammonia production, and transportation to end-users – first for Eastern Europe and on this scale
Renewable Power & Green Hydrogen
At the heart of the Hub is a green hydrogen production facility. New solar photovoltaic and wind farms (around 350 MW combined capacity) will generate clean electricity, which feeds into an electrolyser unit. The electrolyser uses this renewable power to split water into hydrogen and oxygen (via electrolysis), producing emissions-free green hydrogen gas. This hydrogen is then chemically reacted with nitrogen (extracted from air) to synthesise green ammonia NH₃ – an energy-dense fuel and fertiliser
The first phase of the ammonia synthesis plant will have a 100 MW electrolyser unit capacity and yield ~83,000 tonnes of green ammonia per year
Ammonia Storage & Export:
The produced ammonia will be stored safely in liquid form using refurbished cryogenic storage tanks at the port site. Leveraging the port’s existing ammonia infrastructure, Hub can store significant volumes and load ammonia directly onto tanker ships at the deep-water berths or into rail tank-cars for overland transport​
​
Presence of an old ammonia pipeline route in the region also creates opportunities for upgraded pipeline connections, linking the Hub to domestic fertiliser consumers and export terminals.
The Energy Hub will produce 83 ktpa of green ammonia for export. Ukraine currently does not have a significant ammonia export capacity
Energy Storage & Grid Stability
To guarantee reliable operations, the Hub will incorporate a Battery Energy Storage System (BESS). During periods of high renewable energy output (sunny or windy hours), surplus power will charge the batteries. When renewable generation dips (night or calm periods), the batteries discharge to keep the electrolyser and ammonia plant running steadily. This buffering capability ensures continuous hydrogen production despite the intermittency of renewables. In addition, the BESS and the Hub’s flexible electrolysis equipment will provide grid-balancing services – absorbing excess electricity or supplying it to the grid as needed – which helps stabilize the wider Odesa regional grid. This is particularly important as Ukraine rebuilds its energy system and integrates more renewables.
Integrated Design Efficiency
All components of the Hub are co-located within one industrial complex, creating an efficient closed-loop system. This integration minimizes energy losses and transportation costs – for instance, oxygen released by the electrolyser can be piped directly to nearby industrial park tenants who need it, and waste heat from processes could be reused on-site. By sharing utilities and infrastructure, the Hub optimizes operational costs and reduces resource waste. The co-location also improves safety and monitoring
