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 680 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 5+ years of research and a passion for innovating clean energy solutions.

We have been granted the patent and are supported by KTH Holding, Vinnova (Swedish Innovation Agency) and the Swedish Energy Agency (Energimyndigheten).
