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.
