This innovative method offers an efficient and environmentally friendly way to produce hydrogen, with a significantly lower external energy demand compared to traditional electrolysis.
Traditional Electrolysis
In traditional electrolysis, the activation energy required for the reaction is greater than the energy released during the endothermic reaction. This inevitably results in energy loss.
Catalytic Electrolysis
The technology introduced by EF-Hydrogen in the Benelux and Germany for Stellar utilizes an exothermic reaction. By using a catalyst (6% HCl) in combination with an alloy, the activation energy is drastically reduced. The result is a net energy gain, allowing the reaction to sustain itself.
Features
Closed system: The catalyst (HCl) is fully recovered and reused.
Optimized electrodes: A unique coating ensures tthe electrodes remain functional indefinitely without depletion of elements or contamination of the solution.
Low temperature and pressure: The process operates at just 60°C and under a pressure of 0.5 bar.
Technological Breakthrough
The coating on the electrodes plays a crucial role. It allows hydrogen to pass through while preventing contamination buildup. This keeps the electrodes clean and ensures the reaction continues indefinitely.
Efficiency
The numbers speak for themselves: while traditional electrolysis consumes 12,500 MW to produce 250,000 kg of hydrogen, Catalytic Electrolysis achieves the same output with just 375 MW – an astounding improvement in energy efficiency.
Capacity
The offered reactors (40-foot containers) produce up to 32 kg of hydrogen per hour or 250,000 kg annually. This is equivalent to a 1 MW electrolyzer. The Stellar capacity can be scaled up or down by stacking reactors.
The introduction of this technology represents a significant step towards the hydrogen economy. With unprecedented efficiency and broad application possibilities, it provides a solution to both the energy crisis and the challenges of climate change.
