Solar power plants actually get better at making heat right when their pipes start rotting away from the inside out.

The Takeaway
As corrosive salts eat into metal pipes, they create a rough surface that stirs up the flow, making it better at carrying heat. It is a "dead man walking" scenario where the system performs better because it is destroying itself.
From the abstract
Material degradation in molten chloride salts remains a critical barrier to the deployment of high-temperature thermal energy storage (TES) systems in concentrated solar power (CSP) applications. However, existing studies typically decouple corrosion behavior from system-level performance, limiting the ability to assess long-term operational viability. This work presents a multiscale modeling framework that integrates experimentally derived corrosion kinetics with system-level simulations to qua
