Energy Storage Revolutionized
Prometheus delivered the first energy to mankind.
We've tamed hydrogen to continue his work.

Hydrogen is the future of energy. It is abundant, clean, and poised to redefine the global energy landscape. However, its full potential can only be realized by innovative storage solutions that address the challenges of cost, logistics, practicality, and safety.
Our solid-state storage is the key to unlocking this potential, providing the foundation for a hydrogen-powered economy. We are paving the way for a cleaner, more sustainable future by enabling efficient storage, transport, and use of hydrogen.
Solving hydrogen’s storage issue is the key to enabling the hydrogen economy
Clean & Safe
Forget what you know about hydrogen safety. Hydrogen represents clean, safe energy with the potential to revolutionize the global energy landscape.
Storage is Key
Efficient storage defines the feasibility of hydrogen; directly impacting its cost, transport, and practical use.
Solid-State Storage is Essential
Solid-state storage offers unmatched performance and remains the only method with significant potential for improvement, making it essential for unlocking the hydrogen economy.
Prometheus Hydrogen's technologies make
Solid State Storage a reality today
Prometheus Hydrogen offers unique, ground-breaking, and independently validated energy storage and hydrogen power system solutions that are extremely safe and simple to operate.
