Company Overview

Steady Energy is a Finnish deep-tech startup that spun out of the VTT Technical Research Centre of Finland. The company designs, constructs, and operates compact, advanced nuclear heating plants. Its flagship product is the LDR-50, a small modular reactor (SMR) that operates at low temperatures and pressures, specifically designed to provide carbon-free heat for district heating and industrial applications. The company aims to make nuclear heating simple, affordable, and scalable, with a goal of deploying the first commercial nuclear heating plants by the early 2030s.
