Conventional ammonia production is emissions-intensive, relying heavily on fossil fuels. Solid oxide electrolysis enables efficient, high-purity hydrogen production for green ammonia synthesis. As demand for clean ammonia rises across agriculture and energy sectors, the market for low-carbon production technologies is growing rapidly.
Global market
Ammonia is used for fertiliser production. Most hydrogen used in ammonia is produced using fossil fuels, referred to as grey hydrogen, and it represents 38% of existing grey hydrogen consumption. Green hydrogen, produced using renewable sources, will replace this to make green ammonia which can also be used as a clean fuel for shipping, in co-firing power stations and as a hydrogen carrier.
~95GW
potential electrolyser capacity demand
Green ammonia supply is forecast to reach 16.8 million tonnes per year by 2030, with the largest electrolyser installations in China, Europe and North America, representing an electrolyser capacity demand of 95.4GW.
Why Ceres?
Ceres solid oxide electrolysis solutions
- Can provide low-cost hydrogen for an ammonia plant at high efficiency
- Minimise the cost of hydrogen compressors by operating pressurised
- Can be thermally integrated with ammonia synthesis plants to further increase production efficiency by using process heat to generate steam for the electrolyser
- Can follow renewable profiles and take full advantage of the low-cost green power available for the plant
