Renewable energy storage

Energy storage in batteries or chemical fuels such as hydrogen or synthetic natural gas (produced through water electrolysis) will be crucial to the worldwide large scale deployment of fluctuating renewable energies.

As the use of renewable energies grow and technologies mature, the market for storage will gradually increase, offering strong first-mover advantages to a range of potential stakeholders.

Among the different technologies that can be deployed as energy storage, Redox flow batteries and electrochemical generation of hydrogen  have been identified as “strategic”

At De Nora, we are therefore focusing our R&D on:

• pure flow batteries (hydrogen / bromine, and other redox couples),
• hybrid flow batteries (zinc / bromine)
• metal / air batteries.

Regarding water electrolysis, strong efforts are currently being made on Alkaline Water Electrolysis for medium – large scale installations (> ≈ 50 Nm³/h as hydrogen generation capacity).
