E-TAC (Electrochemical, Thermally Activated Chemical) is a revolutionary method for splitting water. Similar to electrolysis, E-TAC uses electricity to split water into hydrogen and oxygen. However, unlike conventional electrolysis, hydrogen and oxygen are generated separately at different phases - an Electrochemical phase and a Thermally Activated Chemical phase.

Phase 1

In the Electrochemical Phase, electricity is consumed and hydrogen is generated. At the same time, the nickel-based anode, similar to the one found in Ni-MH batteries - is “charged”.

Phase 2

In the Thermally Activated phase, the anode is heated up - spontaneously “discharging” it, releasing oxygen.

Energy Efficiency

The process is highly energy efficient.
E-TAC doesn’t require expensive rare-earth metals, and is relatively simple to manufacture, promising low capital costs. The solution’s architecture yields longer durability as well as an overall more robust system. As such, H2PRO’s solution is expected to become the most efficient and effective way to produce sustainable hydrogen at scale.
