with our Unique Patented

with our Unique,
Patent-Pending Technology


Caplyzer is a leading provider of clean energy solutions based on our groundbreaking electrolyzer technology. Our team of experts has extensive experience in the field of energy production and is dedicated to providing innovative and sustainable solutions that can help protect the environment.

Our Approach

At Caplyzer, we believe that technology can play a crucial role in addressing this challenge. Our innovative electrolyzer technology can provide a clean and sustainable solution for energy and resource production. By using our technology, industries can significantly reduce their carbon footprint and decrease their reliance on fossil fuels.

Value Proposition

High Efficiency

Up to 90% efficiency due to decoupling of OER and HER

Dynamic Response

Easy to integrate with renewable energy or intermittent energy sources

Simple Design

Membrane-free stack design with use of earth-abundant materials

Improved Safety

Decoupled gas production reduces the risk of hazardous mixtures


Caplyzer is the world’s first electrolyzers that operate like a
capacitor, simplifying the design at industrial scales

Outstanding innovation in design does not only provide an advantage in terms of cell construction but also successfully addresses the major dilemma of decoupled-water electrolysis. Through our patent-pending technology that works as an electrolyzer-capacitor(thus the name Caplyzer) we have developed this technology for green h2 production.

Made in Sweden the water electrolysis unit consisting of an electrolyzer stack and the electronics necessary to control the operation at desired conditions. The absence of any potential mixing of the gases lead to safer production of highly pure hydrogen or oxygen.


Our electrolyzer technology has diverse applications across several industries.
