Technology
The breakthrough lies in hydrogen storage using salt solutions – a simple yet revolutionary approach to storing hydrogen. This method relies on non-toxic materials and ensures a very high level of safety, redefining the standards for energy storage and transport.
We convert hydrogen gas into a hydrogen rich solution. The reversible process relies on potassium bicarbonate (salt-) and potassium formate (salt+) – two safe and readily available compounds. The simplicity of our approach is the key for its affordability and safety.
