Blykalla is on a mission to change the energy future of the world, by providing green, safe, baseload energy through next generation small modular lead-cooled reactors. Blykalla is a Swedish deep-tech company founded in 2013 by Janne Wallenius, Peter Szakalos and Jesper Ejenstam as a spin-off from the Royal Institute of Technology in Stockholm, where Janne Wallenius carried out research on design and safety analysis on lead-cooled reactor systems since 1996. We develop and build lead-cooled small modular reactors (SMRs) to deliver safe, scalable and carbon-free baseload power supply. Thanks to lead-cooling, we achieve high safety in a very compact format, allowing for a simple and cost effective design that can be mass produced. Our unique reactor design will provide safe and green baseload energy that is a perfect complement to solar and wind power.
