Capacity Added With Demand
Fourth Generation Nuclear Power. A New Paradigm For Energy Production.
Global electricity demand reached 31,779 TWh in 2025 and keeps climbing. Artificial intelligence, electrified transport and heavy industry are all arriving on the grid at once. Meeting it takes power that is carbon free, available every hour, and sited where the demand actually is. Modular construction cuts capital cost and build time compared to large-scale plants. Shorter builds carry less project risk, which brings the total cost of advanced nuclear down to an estimated 50% of large-scale projects.
Driven by clean energy goals and rising electricity demand.
A Breakthrough Materials Innovation. Finally Enabling Commercial Use.
Lead is close to an ideal reactor coolant. It shields radiation, carries heat at atmospheric pressure, and stays liquid across the entire operating range. It has been used as a coolant for over 60 years, but with one key challenge: liquid lead corrodes conventional steel. This is the problem Blykalla solved.
For decades, our founders researched materials that could withstand liquid lead. The answer was a self-healing, aluminum-alloyed steel. It grows a thin layer of aluminum oxide that keeps the lead and the steel apart, and where the surface is scratched, the layer reforms on its own using the oxygen already dissolved in the lead. This is the materials breakthrough that paves the way for commercial deployment.
Now taking lead-cooling to market.
