Ligna Energy AB is a Swedish company that specializes in creating sustainable supercapacitors from waste streams generated by forest industries. The company was founded in 2017 by Magnus Berggren and is based in Norrkoeping, Sweden. The company's journey began in the laboratories of Linköping University, where a material concept based on lignin was developed and commercialized. Ligna Energy has since moved from labs to fabrication and has developed the S-Power 2S, a compact and powerful supercapacitor that is also environmentally friendly. The company aims to provide power sources for the estimated 27 billion IoT devices that will be connected to the internet by 2025, reducing the number of batteries that are discarded daily and pose risks to humans and the environment. The CEO of the company is Peter Ringstad.
