ARENHA

Reliable energy storage has fast become the target technology to unlock the vast potential of renewable energy. Researchers are increasingly investigating the potential of renewable energy storage in the form of liquid ammonia. Its high energy density, carbon-free composition and relative ease of storage make ammonia an excellent energy carrier. The EU-funded ARENHA project plans to demonstrate a flexible and profitable power-to-ammonia-to-usage value chain based on the development of innovative materials. In particular, the project will develop advanced solid-oxide electrolyser cells for renewable hydrogen production, catalysts for low-temperature/pressure ammonia synthesis, solid absorbents for ammonia synthesis intensification and storage and membrane reactors for ammonia decomposition to pure hydrogen (> 99.99 %). The project will prove the competitive potential of ammonia as an energy carrier to produce pure hydrogen for fuel cell electric vehicles and as a possible fuel for internal combustion engines and solid oxide fuel cells.
