Accelerating the transition to Green Hydrogen

Caplyzer’s patented technology is world’s first electrolyzer that operates like a battery, making green hydrogen production safer, cheaper and scalable

Our technology

A patented Supercapacitive Electrolyzer technology simplifying electrolyzer design at industrial scale

Decoupled production

  • Hydrogen and oxygen are produced separately
  • Eliminates risk of gas mixing & increases purity of H2

Membrane-free

  • No expensive membranes with complex assembly
  • Reduces resistance, lowers costs & improves efficiency

No precious metals

  • Designed with use of earth-abundant materials
  • Sustainable, avoid supply bottlenecks, lowers cost

Dynamic response

  • Superior performance even with variable power output
  • Integrates easily with renewable energy sources

About us

Caplyzer is a deeptech startup that aims to transform the hydrogen economy and enable heavy industries to a carbon-neutral future

Over 90% of hydrogen today is produced using fossil fuels, emitting 920 Mt of CO2 annually. Despite rising demand for green hydrogen, current electrolyzers are costly, inefficient with renewable energy sources & have high safety risks.

Caplyzer was born in 2022 at KTH Royal Institute of Technology in Sweden by Professor Joydeep Dutta and Esteban Toledo as a result of their research and a passion for innovating clean energy solutions.

We have a granted patent, are supported by KTH Holding, Vinnova (Swedish Innovation Agency), the Swedish Energy Agency (Energimyndigheten) and behind it is a team with over 30 years of experience and passion for sustainability.
