The ARENHA systems offer a solution to produce, store and use green hydrogen using ammonia as energy carrier. Main exploitable results are foreseen:
1. Advanced SOEC electrolyser for renewable hydrogen generation.
2. Advanced ammonia synthesis loop.
3. Novel ammonia decomposition unit based on a membrane reactor.
4. Advanced ammonia energy storage system capable of storage of massive amount of renewable electricity and long-distance transmission for industrial (feedstock or power) or mobility application.
ARENHA delivers strong environmental, social, and economic benefits by advancing sustainable technologies that support the energy transition and the development of the hydrogen economy.
- SOEC has the potential to become competitive with low-temperature electrolysis technologies, especially in scenarios characterized by high electricity costs and waste heat availability for steam integration to the electrolyser.
- ARENHA integrated Power-to-Ammonia solution based on SOE could become competitive with low-temperature electrolysis-based solutions and traditional ammonia production pathway (this latter in case of low electricity costs and high system utilisation).
- The recovery of H2 from green NH3 (Ammonia-to-Power) using membrane reactors can be achieved at lower costs compared to the benchmark technology. The membrane reactor technology holds significant potential in advancing the decarbonization of the current energy system.
- Preliminary estimates project revenues of approximately €192 million by 2035 for industrial partners involved, with the potential to support around 5,376 jobs through both direct and indirect employment. These numbers are approximately €1,166 million and 32,468 jobs by 2045. ARENHA’s technologies foster high-efficiency, low-emission solutions that reduce reliance on fossil fuels and contribute to global decarbonization. These systems also improve air quality and public health by enabling clean fuel applications. By offering a flexible, storable, and transportable energy vector, ammonia helps integrate higher shares of renewables into the energy mix and avoids the consumption of over 20 million barrels of oil per day. The development and demonstration of ARENHA’s solutions thus play a key role in enhancing energy security, reducing CO2 emissions by up to 10 ton annually, and improving quality of life across sectors while supporting a just and inclusive clean energy transition.
