About Blykalla
Blykalla is Sweden's only SMR vendor, commercializing lead-cooled fast reactors for industrial use. Based on 20+ years of research, their SEALER technology is a compact 55 MWe unit designed to offer a safe, efficient, and scalable power solution. With a strong foundation within Sweden, Blykalla is well positioned to deliver Europe's first advanced SMR, providing reliable and sustainable baseload energy to power AI and clean industries.
Backed by partners such as Uniper, ABB, KSB, Höganäs, and the Royal Institute of Technology, Blykalla has secured close to EUR 50 million in funding, including a SEK 99 million grant from the Swedish Energy Agency and a EUR 17 million investment from the EU. The company plans to complete its first SEALER reactor by 2030 and begin serial production in the 2030s. By 2050, their technology could generate up to 500 TWh of clean electricity annually, cutting global CO₂ emissions by 0.5 gigatons each year.
