OPEN 2018
Madison, Wisconsin
Project Term:
02/04/2019 - 08/03/2022

Technology Description:

The University of Wisconsin’s integrated toolset seeks to expedite molten salt materials development for technology by two orders of magnitude, compared with current methods. The team will combine advances in additive manufacturing, in-place testing for materials/salt compatibility, new molten salt-resistant mini-electrode designs, and machine learning algorithms to optimize and accelerate identification of molten salt corrosion-resistant materials. Those materials can be used in energy applications including molten salt nuclear reactors, concentrated solar plants, and thermal storage.

Potential Impact:

This high-throughput material compatability evaluation technology would dramatically lower the cost required to identify corrosion resistant metal alloy and molten salt pairs. This capability would enable better-performing, lower-cost, and/or more durable molten salt nuclear reactors, concentrating solar power plants, and thermal storage systems and consequently would:


Mitigate the costs and risks associated with adapting to climate change and enable more diversified domestically-produced energy options


Enable proliferation of lower-emission energy technologies


Enhance U.S. economic productivity by reducing the cost of generating electric power
